Hi- I've read many threads about this, but none that solve my problem. I'm trying to upgrade from 10.4.11 to 10.5.2. I have the discs to upgrade, yet when I try to install, I get an error message saying that it can't be installed on my computer - but with no explanation. This is what I've got: Model Name: MacBook Model Identifier: MacBook2,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 4 MB Memory: 1 GB Bus Speed: 667 MHz Boot ROM Version: MB21.00A5.B07 SMC Version: 1.13f3 I am NOT a techie, and am looking for detailed, step by step instructions for whatever I have to do to get this upgrade on my computer. I have an external hard drive to copy all my data to, so not worried about losing anything. Thank you!
When you boot the install disc try reformatting the drive with disk utility. This will remove all your data. Create 1 HFS+ partition and then try to install to that volume. If it still fails check the log which is also under utilities. That should give you the reason why it is failing.
The grey OS discs are machine specific and will only work on the system the grey disc came with. You will need to get a retail version of Leopard to install it on your system.
