deeveedee Posted January 27 Share Posted January 27 (edited) @Thebes Knossos are you noticing any Tahoe performance improvements when you disable Solarium? EDIT: I am currently testing with the following: System Settings > Accessibility > Display > Reduce Transparency: Enabled System Settings > Accessibility > Motion > Reduce Motion: Enabled Terminal: defaults write -g com.apple.SwiftUI.DisableSolarium -bool YES I'm also experimenting with per-app settings like: defaults write com.apple.Preview com.apple.SwiftUI.DisableSolarium -bool YES Edited January 27 by deeveedee 2 Link to comment https://www.insanelymac.com/forum/topic/362254-guide-how-to-disable-liquid-glass-and-big-round-corners/#findComment-2846890 Share on other sites More sharing options...
Thebes Knossos Posted January 27 Author Share Posted January 27 Hi deeveedee, as you know I'm still waiting for metal OCLP patch and this Haswell Acer, so I can't do real animations tests ... I have apply the setting from post 1 to have 'normal' interface with reduced round corners.

deeveedee Posted January 27 Share Posted January 27 (edited) @Thebes Knossos No, I wasn't aware that you didn't have any systems on which to test your proposed settings. Thanks for posting. I have added "Terminal: defaults write -g com.apple.SwiftUI.DisableSolarium -bool YES" to my existing "Reduce Transparency" and "Reduce Motion" settings to see if this further improves Tahoe graphics performance on my hacks.

Thebes Knossos Posted January 27 Author Share Posted January 27 Yes, I'm always waiting for legacy Wifi patch .. and OTA updates are not working too, see my tests here and 2 pages before Link to comment https://www.insanelymac.com/forum/topic/362254-guide-how-to-disable-liquid-glass-and-big-round-corners/#findComment-2846894 Share on other sites More sharing options...
Thebes Knossos Posted January 30 Author Share Posted January 30 A better patch: Instead command: defaults write -g com.apple.SwiftUI.DisableSolarium -bool YES Create the directory under sudo: /Library/Preferences/FeatureFlags/Domain. Then save the following below to SwiftUI.plist via sudo nano. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Solarium</key> <dict> <key>Enabled</key> <false/> </dict> </dict> </plist> Save and reboot 1 Link to comment https://www.insanelymac.com/forum/topic/362254-guide-how-to-disable-liquid-glass-and-big-round-corners/#findComment-2847006 Share on other sites More sharing options...

Thebes Knossos Posted February 2 Author Share Posted February 2 Disabling Liquid Glass works on all components except new control center. I have try with additional command defaults write com.apple.controlcener com.apple.SwiftUI.DisableSolarium -bool YES without succes. The Control Center have just horrible look on my internal panel, hope things change with upcoming releases: Link to comment https://www.insanelymac.com/forum/topic/362254-guide-how-to-disable-liquid-glass-and-big-round-corners/#findComment-2847068 Share on other sites More sharing options...

I have reverted to using just "defaults write -g com.apple.SwiftUI.DisableSolarium -bool YES". I am continuing to use ReduceTransparency and ReduceMotion to improve performance in Tahoe.
