Reezy Posted November 14, 2020 Share Posted November 14, 2020 Hey guys! Yesterday I updated my system from Catalina to Big Sur. There were no issues during the installation and the system has since been running fine with the new OS. But there is one exception: fontd is constantly running at 100 % CPU. This has been going on for the last 15 hours. When I kill it it just comes back within seconds and is at 100 % again. The logging console is flooded with thousands of copies of this message: XType - FontAsset update timer fired. This clearly indicates to me that something is going wrong with fontd. I have no idea what is causing this, but it is somehow locking up this service. What I have tried so far: killing the service -> comes right back at 100 % CPU as soon as some application needs access to fonts clearing the font cache (atsutil databases -remove) -> no effect validating all fonts in Font Book.app -> all fonts are fine removing all user installed fonts -> no effect disabling the service using launchctl -> no effect completely reinstalling the OS -> no effect My setup: macOS 11.0.1 (20B29) OpenCore 0.6.3 config.plist and everything else carefully created using the Dortania guides I don't even think it is related to any Hackintosh stuff and it might just be a bug in Big Sur, but maybe some of you have an idea. The ultimate measure might be a clean install, but I really want to avoid that. Thanks guys! Quote Link to comment Share on other sites More sharing options...
