Is anyone fairly knowledgeable about new Macs? If a Mac system seems to be running poorly and slower after a couple of recent system upgrades..is there a way to "return to previous settings"...as in go back to a recent version of the Mac system before the upgrades? The upgrades I speak of are the ones that come from Apple...basically.
Any help here or in PM would be appreciated.
You should always repair disk permissions after installing new software or upgrades. Applications>Utilities>Disk Utility (Just do "Repair" as there is no need to "Verify".)
For real technical advice about your specific issue, I'd go to apple.com>Support>"your OS version">Forums
You should already have a computer maintenance program: use the free
Onyx from Titanium Software. I run it once a week. If you've never cleaned out your system, this alone can work wonders for speed.
