I just updated my 2008 Mac Pro to Mountain Lion. Now the fans run constantly. I looked at Activity Monitor(all processes) and nothing was using more than 7%...
Any fix for this?
thanks!
Mac Pro, OS X Mountain Lion (10.8.3)
Welcome to the Apple Support Communities
In this case, start resetting the SMC > http://support.apple.com/kb/HT3964 This will reset the fans speed, so check if this solves the problem
Is Spotlight re-indexing? How long since you applied the update?
A lot happens after a numbered update.
Also, what percentage of your startup drive is free space?
That could also be a contributing factor.
I reset the SMC. The update was done yesterday, so Spotlight shouldn't be the issue.
I have166Gb out of 500 available on the startup disk. (This is on a Mac Pro not a Macbook Pro)
tia for any other ideas...
