I've just upgraded from mavericks to yosemite, the download was sluggish but eventually worked so I don't think any of the files were corrupted. There was no hitch with the installation as far as I know either. All I know is that when I woke up after leaving my MacBook Pro (15 inch, mid-2010) its fan was spinning out of control at the login screen.
When I restarted and looked at the activity monitor I saw that core audio and launchd were the culprits. I've tried the following to fix my problem:
- Clearing the PRAM.
- Clearing the SMC.
- Deleting the plist for the audio preference pane.
- Verifying disk permissions.
- Repairing disk permissions.
Additional info: I've run etreCheck a few times and have fixed most of the things it pointed out, all that is left is:
System launch daemons with problems : [fail] com.apple.systemstatsd.plist
Launch daemons with problems : [invalid?] com.adobe.SwitchBoard.plist Aide
I've searched and haven't found any answers that worked yet. Anything else I can do apart from a reinstall?
Also I've noticed that bluetooth can't be turned off anymore although it doesn't actually seem to be on, any fixes for that would be appreciated too.
