disabling liquid glass on macOS 26 because it's a rushed piece of crap

are you a macOS beta tester? did you install macOS 26 on your main device even though literally everyone told you not to? well, congratulations, i've discovered a way to make you feel slightly better about your poor decisions.

simply un-Tahoe-ing macOS!

thanks to Apple Engineering™, we are able to simply disable the redesign (internally called "Solarium") and restore our mac almost completely 1-1 with how it was in sequoia.

to start, create the directory /Library/Preferences/FeatureFlags/Domain. save the following as SwiftUI.plist then FULLY REBOOT.

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
  <plist version="1.0">
  <dict>
      <key>Solarium</key>
      <dict>
          <key>Enabled</key>
          <false/>
      </dict>
  </dict>
  </plist>
