Fonts in Safari, Google Chrome or Mac Mail display incorrectly when Suitcase Fusion is running.
Some Suitcase Fusion users have reported text rendering problems on certain websites while using Apple's Safari and Google's Chrome web browsers (and sometimes the Mac Mail application). If you're seeing font substitution, garbled fonts, incorrectly bold fonts, or hieroglyphics, then your web browser is confused and is displaying a font that is either currently active or was used recently, instead of the system font that the web page requested. There are several ways to address this issue:
1) Clear System Font Caches
If text in your web browser still looks strange, use Suitcase Fusion to Clean Font Caches. From Suitcase Fusion's File menu select Clean Font Caches. This will purge your system font caches. Once this is complete, restart your Mac.
Additional applications, such as Font Nuke can also assist in cleaning out and resolving Font Cache issues. Please visit their site here:
2) Minimize your system fonts
Try minimizing your system fonts by following the recommendations appropriate for your operating system:
Please use this guide to minimize your macOS system fonts.
3) Deactivate all "web-safe" fonts in Suitcase Fusion
If you have a Postscript version of a "web-safe" font (fonts commonly used on the web) active in the Suitcase Fusion "Font Library", then that can confuse your web browser. Deactivate the font and refresh your web page.
Web Safe Fonts:
Arial Bold Italic
Arial Italic Arial
Comic Sans MS Bold
Comic Sans MS
Courier New Bold Italic
Courier New Bold
Courier New Italic
Georgia Bold Italic
New Roman Bold Italic
Times New Roman Bold
Times New Roman Italic
Times New Roman
Trebuchet MS Bold Italic
Trebuchet MS Bold
Trebuchet MS Italic
Verdana Bold Italic
Note: If you are a web developer or spend a lot of time on the web, then it makes sense to:
a) Remove the above "web-safe Fonts" from Suitcase Fusion
b) Copy them to [Macintosh HD]/Library/Fonts
c) Fonts placed here are activated by Mac OS X itself and will always be available for you across all web browsers with out needing an external font manager.
4) Use the Chrome Font Changer Extension
Try using the Chrome Font Changer extension. It allows you to change fonts on a webpage on the fly, replacing garbled text with another font of your choosing from your Font Library.

5) Use Firefox or another non-Webkit Browser
Use a web browser that does not use Apple's Webkit framework, such as Mozilla Firefox: Firefox, and tends to have less font-rendering issues.
