My machine asked to be switched off after OSX was installed. It then would not boot. I had an Apple approved technician come to my home and get the machine to at least boot. But it is so slow a 386 would be faster. Should I clear my disk? I have backed up the machine prior to the first download.
iMac, Mac OS X (10.6.7)
First backup to a storage drive using the emergency quick copy method, then disconnect the external drive, do NOT rely solely upon TimeMachine.
Most commonly used backup methods
Next follow this procedure for reinstalling OS X 10.6, Security Zero Erase the entire drive in Disk Utility (important)
How to erase and install Snow Leopard 10.6
Update fully to 10.6.8 and exrtract your free iLife from your 10.5 disks or buy new from AppStore if needed.
Run the machine with no files returned for some time to rule out a hardware or file problem, then return copies of your files from backup and then make a TimeMachine and/or bootable clone drive.
Don't upgrade to 10.7 or 10.8 as that won't run your older software and slows older 10.5 era machines down quite a bit
