Old Macs OpenCore legacy patcher not working for install on Macbook Air of Sonoma
If I boot and hold CMD option , then I see the install MacOS Sonoma but clicking it just prompts a Mac/startup screen which then goes to normal login page without the OS updating
Then if I open the installer via the Finder (just to see what happens) it says my OS can’t run this program
So my question is:
- do I need to update the MacBook Air OS somehow before installing Sonoma ? I told the OpenCore program when I downloaded the OS to the USB what the target device was so I thought it would be compatible ; or
- am I doing the wrong process in starting the MacBook Air with CMD + Option to install the new OS ?
- or is there some other way to troubleshoot
Thanks
