After 4–5 years, my MacBook Air M1 16GB has met its match: macOS Tahoe is slow on it. Double screen with 5K external monitor.
Partly a story as old as old operating systems: "visual treats" slow the computer down. Partly: feels bloated. Hopefully some is "new install" settling.
Liquid Glass is nice on iPad and iPhone, but weird on Mac. I sometimes cannot see which Safari window is active as the title bars look so different (depending on Safari window content). Crazy.
Third party apps seem to work quite well, including "background" stuff like Keyboard Maestro etc.
I've now turned on a couple of Accessibility features:
- reduce motion, because I didn't like the "physics" of scrolling in Messages.app
- reduce transparency: after which some performance returns
Enjoying things belonging where they should:
- Journal.app on macOS (and iPadOS).
- folders have colours and symbols
- Spotlight (as Launchbar/Quiksilver/Butler etc) works much better.
