Not sure if this is the right sub but i'll ask anyway, hopefully anyone can help me.
So I found 2 MacBook Pros from my workplace and the manager said I can keep them. They're a Mid-2012 13 inch and a late 2011 13 inch. I wanted to move my SSD and RAM to the 2011 because the 2012 only has the left tinny sounding speaker working and I was going to sell the 2012 instead. The 2011 is in better physical shape, I didn't mind about the slightly lower specs as I already have a Main Computer i use daily. But when i put the SSD in 2011, it refuses to upgrade to High Sierra, while I create a bootable usb the whole system crashes, try internet recovery, gets stuck while updating, tried a bootable usb it says failed firmware update, with the HDD it worked fine. The only way I was able to get High Sierra was to download it on 2012 MacBook and then put the SSD in the 2011 and then it worked, but when I tried using OpenCore legacy patcher, everything worked but creating the USB Install the whole system froze again. Does anyone know what the issue is? Is the SSD Incompatible?
Edit: Forgot to mention I did swap the SATA cable between 2011 and 2012 and the 2011 the problem still persisted
