I have a macbook that has lion installed but I want to downgrade to 10.5. I have the 10.5 install discs which came from an older iMac. Will I be able to simply insert the discs to remove lion and install 10.5?
Could I downgrade my MBP late 2011 to snow leopard? the MBP came installed with lion, which I have several issues with.
I need to reinstall OS on my MacBook Pro. It originally came with OS X 10.5, then I upgraded to OS X 10.7. When I use the original CD's that came (10.5) and reboot, it just starts rebooting and I never get to the installation page.
Same applies when I access the 10.5 CD and reboot from the installation point "Click the button below to restart your computer and begin the installation process."
Am I doing something wrong? I think I should be able to downgrade to the original OS with the original software? Need to do a clean install since I don't think I can do it with 10.7 as I bough that one on the App Store. At least I don't know how to do it. When I login to the App Store, it tells me the 10.7 is installed, and it's grayed out.
Any help is greatly appreciated.
To help with the Lion problem in the App Store. When opening the Mac App Store hold down the Option key and now Lion won't be greyed out and you can go about your day no problems.
Not sure what is happening when booting. As long as the Disk's are the Grey machine specific installation media then you should be fine.
Did you hold down the 'c' key or 'option' key when trying to boot from the DVD??
Cheers
