mavericks system preferences problem
System Preferences panel says: Preferences Error...You can't open because it dosen't work on intel-based Mac. True on Mac 27" and Mac Mini just purchased last month.
Mac Mini, Mac OS X (10.4.10)
You have 90 days of free AppleCare telephone support, I'd recommend you all AppleCare immediately. I suspect either your download of Mavericks or the install went haywire.
BTW you can easily reinstall Mavericks by restarting, when you hear the start up tone hold down the Option Key and then select Install OS X and install to your internal drive. Don't worry all your data will be in-tact however that being said it is ALWAYS smart to backup prior to any major update or change.
