Ok, thx!
From a clean install:
1- iCloud contacts are not working. Contact app crashes when iCloud contacts are enabled. There is nothing wrong in my contacts. I deleted all my contacts (of course after an export for local use) and still it doesn't work.
2- Safari bookmarks aren't shown.
These 2 have always been only problems since first beta release. Nothing changed with GM. Is there any option to do a "clean set up" for iCloud?
Dashboard doesn't work; Notifications doesn't work; Hot Corners don't work.
