Mac 10.10 Yosemite available

Just downloaded it and and installed on a spare HD and running now.
Seems to be running nice.
If you've signed up for it goto to:

Seems to be suffering the usual Apple problems of server overload atm.

Oh, sorry - didn't spot this:

Been playing for a couple of days - seems quite solid (although I can't enable iCloud Drive 'cos I still use the old system).

Visually a very nice refresh and so far everything I use seems to play nicely. Some finder actions maybe a bit slow.

I installed this last night.

First thing I seem to have problems with is that iTunes does not load.

Not really used much else yet but will post once I have.

Have you downloaded iTunes 12?

I suspect Yosemite requires it.

Yeah, it popped up in the App Store as an update so I loaded it. Well, I think I did.

Has the dock icon turn red?

Yep, it red. Still doesn't load up.

Hmm. Mine's been trouble free. Delete the com.apple etc prefs file?

What files do I need to delete and from where?

I'd try

~/Library/Preferences/com.apple.iTunes.plist and nearby files as a start

(You have to hold down the option when using the Go menu to get to the Library)

No quarantees of course, but borked pref is always a good place to start.

If that doesn't work, trash ~/Music/iTunes Music Library.xml (If I remember rightly, you will be prompted to create a new file at launch)

Also, don't forget to use the feedback agent.
