The humble font isn’t as humble as you might think, especially on a Mac. Fonts are more like plug-ins than you’d imagine, and because they’re loaded by macOS and the apps that run on it, a bad font can have some unexpected consequences.
Those consequences can range from the relatively benign, like some characters being displayed incorrectly, to something more annoying, like apps refusing to load or functions not working quite as they used to. Faulty fonts are rarely the cause of macOS system problems, but if you’re experiencing issues that don’t make a great deal of sense, checking out your fonts is a great first troubleshooting step to take.
Thankfully, Apple includes a tool for installing, validating and generally troubleshooting fonts with each Mac. The next time your Mac is misbehaving, and you’re out of ideas, validating your fonts is a good troubleshooting step.
How to Validate Fonts on a Mac
To begin, open the Font Book app. You’ll find it in your Applications folder. (Open Finder and click Go > Applications to open the folder.) Once open, select all of your fonts by clicking one and pressing Cmd+A.
Right-click one of the fonts and click “Validate Fonts.”
Once the validation is complete, a new window will appear confirming whether any of your faults are damaged. A green icon indicates they’re fine, a yellow icon indicates there are warnings about the font, and a red icon indicates validation failed.
How to Remove Damaged or Duplicate Fonts
If any of your fonts are indeed damaged, tick the checkboxes next to them and then click the “Remove Ticked” button.
The selected fonts will be removed from your system. If this is indeed required, restart your Mac once the fonts have been removed.
Для использования шрифтов в приложениях необходимо сначала установить их с помощью приложения «Шрифты». Во время установки шрифтов приложение «Шрифты» отображает все проблемы, найденные для данных шрифтов. Проверку шрифтов можно также выполнить позже.
Установка шрифтов
На Mac можно сделать следующее.
В приложении «Шрифты» нажмите кнопку «Добавить» в панели инструментов, найдите и выберите шрифт, затем нажмите «Открыть».
Перетяните файл шрифта на значок приложения «Шрифты» в Dock.
Дважды нажмите файл шрифта в Finder, затем в появившемся диалоговом окне нажмите «Установить шрифт».
При установке шрифта приложение «Шрифты» автоматически проверяет его на наличие ошибок.
Установленные Вами шрифты могут быть доступны только Вам или любому пользователю компьютера в зависимости от размещения, заданного по умолчанию для установки шрифтов. См. раздел Изменение настроек приложения «Шрифты».
Загрузка системных шрифтов
Системные шрифты, доступные для загрузки, затемнены в списке шрифтов в окне приложения «Шрифты».
В приложении «Шрифты» на Mac нажмите «Все шрифты» в боковом меню.
Если боковое меню не отображается, выберите «Вид» > «Показать боковое меню».
Выберите затемненное семейство шрифтов либо один или несколько затемненных стилей.
В панели предварительного просмотра нажмите «Загрузить», затем в появившемся диалоговом окне нажмите «Загрузить».
Если панель предварительного просмотра не открыта, выберите «Вид» > «Показать окно просмотра». Если кнопка «Загрузить» не отображается, переключитесь на другой режим предварительного просмотра. (Кнопка «Загрузить» недоступна в режиме просмотра информации).
Проверка шрифтов
Если шрифт отображается некорректно или документ не открывается из‑за поврежденного шрифта, проверьте шрифт на наличие ошибок и удалите этот шрифт.
В приложении «Шрифты» на Mac выберите шрифт, затем выберите меню «Файл» > «Проверить шрифт».
В окне «Проверка шрифтов» нажмите стрелку рядом со шрифтом, чтобы просмотреть сведения о нем.
Зеленый значок свидетельствует о том, что шрифт прошел проверку; желтый значок означает предупреждение, красный — что обнаружены проблемы.
Установите флажок рядом со шрифтом, не прошедшим проверку, затем нажмите «Удалить выбранные».
Совет. Чтобы найти предупреждения или ошибки в длинном списке шрифтов, нажмите всплывающее меню вверху окна «Проверка шрифтов», затем выберите «Предупреждения и ошибки».
Устранение дубликатов шрифтов
Если шрифт является дубликатом, то рядом с ним отображается желтый значок предупреждения.
В приложении «Шрифты» на Mac выберите меню «Правка» > «Найти включенные дубликаты».
Выберите нужный параметр.
Устранить автоматически. Приложение «Шрифты» выключает дубликаты шрифтов или переносит их в Корзину в зависимости от настроек приложения.
Устранить вручную. Перейти к следующему шагу для просмотра и устранения дубликатов шрифтов вручную.
Просмотрите дубликаты и решите, какой из них сохранить.
Копия, которую приложение «Шрифты» рекомендует использовать, выбрана и отмечена как «Активная копия». Для просмотра других копий выбирайте их.
Нажмите «Устранить этот дубликат». При наличии нескольких дубликатов нажмите «Устранить все дубликаты».
Если нужно переместить неиспользуемые шрифты в Корзину, установите флажок «Устранять дубликаты перемещением дублированных шрифтов в Корзину».
В некоторых приложениях, таких как Почта или TextEdit, можно выбрать шрифт, который будет по умолчанию использоваться в приложении. Подробнее см. во встроенной справке соответствующего приложения.
Your Mac comes with many built-in fonts, and you can download and install more from Apple and other sources. If you don’t want a font to appear in your apps, you can disable or remove it.
Install fonts
Double-click the font in the Finder, then click Install Font in the font preview window that opens. After your Mac validates the font and opens the Font Book app, the font is installed and available for use.
You can use Font Book preferences to set the default install location, which determines whether the fonts you add are available to other user accounts on your Mac.
Fonts that appear dimmed in Font Book are either disabled (“Off”), or are additional fonts available for download from Apple. To download the font, select it and choose Edit > Download.
Disable fonts
You can disable any font that isn’t required by your Mac. Select the font in Font Book, then choose Edit > Disable. The font remains installed, but no longer appears in the font menus of your apps. Fonts that are disabled show ”Off” next to the font name in Font Book.
Remove fonts
You can remove any font that isn’t required by your Mac. Select the font in Font Book, then choose File > Remove. Font Book moves the font to the Trash.

macOS supports TrueType (.ttf), Variable TrueType (.ttf), TrueType Collection (.ttc), OpenType (.otf), and OpenType Collection (.ttc) fonts. macOS Mojave adds support for OpenType-SVG fonts.
Legacy suitcase TrueType fonts and PostScript Type 1 LWFN fonts might work but aren’t recommended.
Stay away from corrupt font files on a Mac

Fonts seem like innocuous files, and most times, they are. However, like any computer file, fonts can become damaged or corrupt. When that happens, they can cause problems with documents or applications. Use Font Book on your Mac to validate installed fonts to ensure that the files are safe to use.
Information in this article applies to Font Book in Macs with macOS Big Sur (11) through OS X Panther (10.3).
If a font doesn’t display correctly in a document, the font file may be damaged. If a document won’t open, it’s possible one of the fonts used in the document is the problem. Using Font Book, you can test fonts for problems and remove them.
You can also validate fonts before you install them to head off future problems. Validating fonts at installation cannot prevent the files from becoming damaged later, but it prevents you from installing problem files.
Font Book is included with macOS Big Sur (11) through OS X 10.3. You can find Font Book in the Applications folder. You can also launch Font Book by selecting the Go menu in the Finder menu bar, choosing Applications, and then double-clicking the Font Book application.
How to Validate Installed Fonts With Font Book
If you have a problem with a font, check it in Font Book. You can also verify all fonts on your Mac occasionally to err on the side of caution. Here’s how to validate installed fonts in Font Book:
Open Font Book by clicking it in the Applications folder or by accessing it from the Go menu.
Select the font or fonts you want to validate by selecting the font name or names in the list of fonts in Font Book. You may have to scroll down to find the font.
Select File in the Font Book menu bar and choose Validate Font from the drop-down menu.
Evaluate the results in the Font Validation window. Hopefully, you’ll see all green circles with check marks in them next to the font names, which indicates the fonts are safe to use.
If you see a problem font indicated by a red circle with an X in it, select the check box next to the font name and select Remove Checked to delete it.
You are prompted by your Mac to enter your password before it removes the damaged font.
If you have a large number of fonts installed, you can validate them all at once, rather than selecting individual fonts or font families. Select Edit on the Font Book menu bar and choose Select All. In the File menu, select Validate Fonts, and Font Book validates all the installed fonts.
Remove Duplicate Fonts
If you validate all your fonts, you may find duplicate fonts. A banner at the bottom of the Font Book screen notifies you if you have duplicates.
Choose Resolve Automatically to remove duplicates all at once without a review. A more cautious approach is to select Remove Manually to find out more about the duplicate fonts on your Mac.
Each font with a duplicate is displayed, one at a time. You are shown samples of both fonts, and the active copy is identified. You can choose to resolve the duplicate, which moves the inactive copy to the trash, or you can leave everything as is.
If you do plan to remove duplicate fonts, make sure you have a backup of your Mac’s data before proceeding.
How to Validate Uninstalled Fonts With Font Book
If you have collections of fonts on your Mac that you have not installed, you can wait until you install them to validate them, or you can check them in advance and toss any fonts that Font Book labels as possible problems.
Font Book is not foolproof, but chances are if it says a font is safe to use (or that it has problems), the information is correct. It’s better to pass on a font than risk problems down the road.
To validate a font file before installing it:
With Font Book open, select File in the menu bar and choose Validate File.
Locate the font on your computer. Click once on the font’s name to select it, then select Open. (Select multiple fonts by holding down the Shift key and clicking the fonts you want to validate.)
The font validation window displays whether the chosen font is safe to install or has potential problems. If the font is OK, place a check mark in front of its name and select Install Checked to install the font. If the font has problems, it is best not to install it.

To begin, open the Font Book app. You’ll find it in your Applications folder. (Open Finder and click Go > Applications to open the folder.) Once open, select all of your fonts by clicking one and pressing Cmd A.
Right-click one of the fonts and click “Validate Fonts.”

How to Remove Damaged or Duplicate Fonts
If any of your fonts are indeed damaged, tick the checkboxes next to them and then click the “Remove Ticked” button.
The selected fonts will be removed from your system. If this is indeed required, restart your Mac once the fonts have been removed.
To use fonts in your apps, you need to install the fonts using Font Book. When you’re installing fonts, Font Book lists any problems it finds for you to review. You can also validate fonts later.
On your Mac, do any of the following:
In the Font Book app , click the Add button
Drag the font file to the Font Book app icon in the Dock.
Double-click the font file in the Finder, then click Install Font in the dialog that appears.
When you install a font, Font Book automatically validates or checks it for errors.
Fonts you install are available only to you, or to anyone who uses your computer, depending on the default location you set for installed fonts. See Change Font Book preferences.
Download system fonts
System fonts you can download appear dimmed in the font list in the Font Book window.
In the Font Book app on your Mac, click All Fonts in the sidebar.
If you don’t see the sidebar, choose View > Show Sidebar.
Select a dimmed font family or one or more dimmed styles.
Validate fonts
If a font isn’t displayed correctly or a document won’t open due to a corrupt font, validate the font to find issues and delete the font.
In the Font Book app on your Mac, select a font, then choose File > Validate Font.
In the Font Validation window, click the arrow
A green icon indicates the font passed, a yellow icon indicates a warning, and a red icon indicates it failed.
Select the checkbox next to a failed font, then click Remove Checked.
Tip: To find warnings or errors in a long list of fonts, click the pop-up menu at the top of the Font Validation window, then choose Warnings and Errors.
Resolve duplicate fonts
If a font has a duplicate, it has a yellow warning symbol next to it in the list of fonts.
In the Font Book app on your Mac, choose Edit > Look for Enabled Duplicates.
Click an option:
Resolve Automatically: Font Book disables or moves duplicates to the Trash, as set in Font Book preferences.
Resolve Manually: Continue to the next step to review and handle duplicates yourself.
Examine the duplicates and their copies, then select a copy to keep.
The copy that Font Book recommends keeping is labeled “Active copy” and is selected. To review other copies, select one.
Click Resolve This Duplicate or, if there’s more than one duplicate, Resolve All Duplicates.
If you want the inactive copies to go in the Trash, select “Resolve duplicates by moving duplicate font files to the Trash.”
In some apps, such as Mail or TextEdit, you can select a font to use as the default in the app. For more information, search the built-in help for the app.

I’ve found that I have serious problems with font validation in 40% of my fonts. Many of these are system fonts I cannot simply remove or disable. How can I best replace or repair these fonts. Older advice I’ve found about diskutil repairPermissions seems to be outdated as diskutil no longer has such a command listed.
I’ve run first aid from Disk Utility normally and in Recovery Mode and found no issues with the drive.

Hello! I didn’t get any emails about replies to my question, so just seeing all these comments now. I have since removed all fonts that were possible and was left with PingFang.ttc and Symbol.tcc
The computer already seems to be running more smoothly, but is still hanging a bit. I’ll report back after I’ve had a chance to look over these responses and make another attempt.
Sep 29, 2018 8:05 AM
I went through the steps you suggested and had hopes it was all solved. I started up Font Validation, and now instead of just Ping Fang and Symbol throwing System Validation errors, now I’m getting errors on all fonts that follow PingFang in the list!
Sep 29, 2018 8:31 AM
It may have been this way before I removed problematic fonts but only PingFang and Symbol were unable to be removed.

Is it possible my restore volume or just its fonts are somehow corrupted, resulting in a problematic install every time? I feel like this machine has always felt painfully slow, perhaps this is a root cause?
Luckily this machine is basically only used as a media player.
When I first got it, I ran it off an external drive because I wasn’t sure I’d keep it. It was fine that way. Is there a way to restore the restore volume from a network source? I reinstalled the whole thing a year ago and it seemed fine at first but quickly began to exhibit the same symptoms. I feel like this is getting closer to the cause but not quite.
To change the text font in HTML, use the style attribute. For example, click on the Paragraphs menu and you’ll see the Moxy Roxie download from Fontsly.com various style options for paragraphs in style tab like Scripts, Font Family, Font Weight, etc. It will look funny if one of your newsletter typefaces is in Comic whereas the other one was in Times New Roman. Now with retina displays, and 4k screens, serif fonts are becoming more readable on the web. Downloading web fonts is as easy as finding it and downloading the in eitherOTF (OpenType Font) orTTF (TrueType Font) format. Crimson Text -a serif font inspired by old-style typefaces- for the headings, combined with Work Sans -a modern, kind of grotesque sans-serif- for the body, make a solid combination of tradition + modernity.
After the payment process is complete, the fonts you have licensed become available in your Typotheque account for download. There are other aspects that can differ among font styles, but more often these are considered immanent features of the typeface. Which is why Sans-Serif is a great typeface for the body of text. A CSS Reset (or Reset CSS”) is a short, often compressed (minified) set of CSS rules that resets the styling of all HTML elements to a consistent baseline. Once you’ve done that, you’ll need to add the font to your stylesheet. Use a base font size of 16 CSS pixels. You should use the and files as a starting point to add your code to (see the live example ). Make a copy of these files in a new directory on your computer now.
The Latest On Clear-Cut Secrets In Popular CSS Fonts
Web browsers normally ignore extra spaces in the HTML of a page, reducing them to a single space character between words and other elements as described on Nonbreaking Spaces The pre” option functions just like the HTML tag: Extra white space (like tabs, multiple spaces, and hard returns) that you put in the HTML code appear in the document window (see Editing Styles for more on this option). Font-style: The default value is normal. You can add and install new fonts to inject some personality into your work. RGCA is supported in all modern browsers, so you can use these values with confidence that it’ll work for most viewers, but you can also set an easy fallback.

To style the text within a table, you use the same CSS properties that you would use in styling any text. The font will appear in the Fonts window and in other applications on your system after it’s installed. The Web Open Font Format (WOFF) is a web font format that is compatible with multiple web browsers and web viewers, including the latest versions of IE, Firefox, Chrome, Opera and Safari. Browsers pick the first one that is embedded in the page using @font-face or installed on the operating system. Fa-example padding: 15px; color: white; background-color: gray; border-radius: 50%; font-size: 1.5em; Using the i element produces the cleanest code.
Although I discovered this late, it likely predates Facebook’s code above and may even be the origin of this aliased approach for system fonts. Evolve Sans includes 10 fonts in multiple weights and a futuristic alternate that’s fun for specific characters or uses. Like the monospaced fonts described above, this font is reminiscent of typewriter text and has a mechanical quality. Do research and choose carefully, as some say, that this font family tends to make readers skim through content. They’re more calligraphic than other sans-serifs, meaning they have a greater variation in line widths. After the font preview opens, in the Font Book window click the Install Font button.
The result is IE and other browsers whose defaults are not set in px give users who have not made further corrections 20px @ 12pt instead of 16. Recently, FontFont, in my opinion one of the better foundries in the world, introduced several typefaces to Typekit. Modern monitors display both fonts equally well. These fonts have become popular for their clarity and saved the day for designers in the past, who would attempt displaying fonts in small sizes. Dubiel, a classic inspired font, designed by David Rakowski has long thin serifs in an elegant style. In browsers and apps that do not support SVG color fonts, the fonts will fallback to monochrome glyphs.

Whether you want to use a new font in a Word or just change your operating system’s system font to give it a different look, you’ll first have to install the font on your operating system.
The installation process makes the font available to all programs on your operating system. Most applications don’t allow you to simply load a font file and use it — they provide a list of installed fonts for you to choose from.
Warning: Too Many Fonts Can Slow Down Your Computer
Having too many fonts installed can slow down your computer. Don’t go out of your way to install a large number of fonts for no particular reason — install only fonts you actually want to use. Don’t uninstall fonts that came with your operating system, but feel free to uninstall fonts you’ve installed after you’re done using them.
This slow-down happens with all operating systems — Windows, Mac OS X, and Linux. The operating system has to keep track of the larger amount of fonts, and each program that uses fonts will have to load and deal with them.
Windows
To install a font on Windows, download it in OpenType (.otf), PostScript Type 1 (.pfb + .pfm), TrueType (.ttf), or TrueType Collection (.ttc) format. Right-click the downloaded font file and select Install. If the font file comes in an archive — such as a .zip file — extract it first.
You’ll find a list of installed fonts in your Fonts folder. Open the Control Panel, click Appearance and Personalization, and click Fonts to access it. You can also press the Windows key once to open the Start menu or Start screen, type “Fonts” to search your system, and click the Fonts folder shortcut that appears.
From here, you can preview your installed fonts. Uninstall a font by right-clicking it and selecting Delete. To install multiple fonts at once, drag and drop them into the Fonts window.
Mac OS X
To install a font on Mac OS X, download it in OpenType (.otf), TrueType (.ttf), Datafork TrueType Suitcase (.dfont), or an older type of font file Macs supports, like PostScript Type 1. Double-click the downloaded font file to preview it. Click Install Font in the preview window to install it.
You’ll find a list of installed fonts in the Font Book application. To open it, open the Finder, click Applications in the sidebar, and double-click Font Book. You can also open Launchpad and click the Font Book shortcut. To launch it from your keyboard, press Command + Space to open Spotlight search, type “Font Book,” and press Enter.
Preview a font by clicking it. To remove a font, right-click it and select Remove “Font Name” Family. To disable a font you’ve installed, right-click it and select Disable “Font Name” Family. You can then re-enable it from the same menu later.
To install multiple font files at once, drag and drop them onto the Font Book window.
Linux
Different Linux distributions come with different desktop environments, and those different desktop environments contain different applications for this.
To install a font, first download it in TrueType (.ttf), PostScript Type 1 (.pfb + .pfm), or OpenType (.otf) format. You can then double-click the font to preview it. On Ubuntu or any other GNOME-based Linux distribution, GNOME Font Viewer will appear. Click the Install button to install the font for your user account.
You can install fonts manually — or install multiple fonts at once — by placing them in your user account’s .fonts directory. First, open your Home directory in a file manager. In Nautilus, click View > Show Hidden Files to view hidden folders. Locate the .fonts folder and double-click it. If it doesn’t exist, right-click in your home directory, create a new folder, and name it .fonts. Place font files in this directory to install them for your user account.
You will need to update your font cache before fonts you place in this folder are available in applications. Open a terminal and run the fc-cache command.
To delete a font, open the .fonts folder in your home directory and delete the font files from there. If you added the font with GNOME Font Viewer, browse to the .local/share/fonts directory in your home folder instead. Run the fc-cache command afterward to unregister the fonts from the system.
If you need to use a very large number of fonts for some reason, you may want to use a font management program. You can load all your fonts into a single program so you can preview and manage them in one place. You can then use the font management program to install the fonts on your system when you need them and uninstall them when you don’t, avoiding slowdowns.
