- Install process was a train-wreck. Installer misconfigured my update (since this is GM, I foolishly updated my day-to-day SL), and the OS wouldn't boot. My internet was down, so I couldn't reinstall. Basically bricked my computer. Led to my first backup/reinstall as an Apple customer (> 6yrs). Not impressed.
- Mail, Contacts, Calendars does not support Address Book for Gmail (you have to go to Address Book > Sync with Google)
- You cannot resize icons in the Launchpad (I'm on a non-multitouch MB, so I don't know if there's a gesture)
- Why exactly do you need a multitouch trackpad for inertial freaking scrolling?
- CTRL+scroll doesn't seem to work for zooming the screen (I've enabled it in settings, but still nothing)
- AirDrop: where?
- All My Files impressively fast, completely useless
- Mission Control is ugly with 2 windows
- hold ctrl, press left/right to switch desktops. You need to release and repress ctrl before pressing up to go to M/C.
- I want devices above favourites in the finder sidebar
- Can't hide apps from launchpad
- Check out the Microsoft-style blue gradients in the help!
- I'm sure I'll find more. Apple seem to have removed (or "removed" by changing completely and poorly documenting) as many features as they've added.
Sometimes I think the new OS is great, sometimes I hate it. Never been so polarised with an OSX release before.
