I am having trouble with my almost 4 yr old iMac (version 10.6.8) and am thinking about getting a "new" Mac but I like my 21" screen.

Question

Would it be  possible to hook up a Mac Mini or laptop to my iMac's screen?  Thanks.

Answer 1

Have you reset the SMC?
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
While you're at it, resetting the PRAM won't hurt anything and 'might' help is SMC reset didn't work (PRAM does some port control):
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Something else you might try .... you don't say how you're updating to 10.6.8, however, if you're using Software Update, you might try downloading the 10.6.8 combo update, which contains all updates to 10.6. Sometimes, Software Update doesn't work quite right, and installing the combo update fixes that. Download the update from Apple's download site at http://support.apple.com/downloads/ , using Disk Utility repair permissions, apply the combo update, then repair permissions again.
