My G5 will sometimes take several reboots to login. Once logged in, it will lock up if idle for several minutes.  Logic board has been fixed.  New hard drive has been installed. Memory check shows no errors.  Any ideas?


iMac, Mac OS X (10.7)

    You show as using Lion 10.7. That means you have an Intel iMac not a PPC G5 iMac.

     

    Or is this a different iMac?

    I'll verify the OS Version.  It's the highest OS Level for a PPC.  Sorry, I'm still kind of new to the Mac World.

    The highest version of OS X for a PPC Mac is Leopard OS 10.5.

     

    Please go to your Finder Menu/Apple/About this Mac and copy the results here.

     

    Do NOT include your Mac's serial number.

    You don't have a lot of RAM but 1GB will suffice.

     

    One more question:

     

    How much free space do you have on your hard drive?

    Klaus,

     

    I have roughly 350GB free.  A new 500GB drive was put in machine prior to me owning it.

     

    I used the Disk Utility to check the drive and found that there were no evident drive errors.

     

    Thank you for taking the time to try and assist me.

     

    Regards,

     

    Bob C

    So that's not it then!

     

    Did you also repair permissions?

     

    Repairing permissions is important, and should always be carried out both before and after any software installation or update.

     

    Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).

     

    In First Aid, click on Repair Permissions.

     

    This only takes a minute or two in Tiger, but much longer in Later versions of OS X.

    and here:

    An article on troubleshooting Permissions can be found here:

     

    http://support.apple.com/kb/HT2963

     

    By the way, you can ignore any messages about SUID or ACL file permissions, as explained here:

     

    http://support.apple.com/kb/TS1448?

     

    If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.

     

    Once that is complete reboot again from your usual start-up disk.
