Can I upgrade macOS again after downgrading
Hi all,
I have a 17'' MacBook Pro suffering from the infamous gpu failure. This laptop is great and I don't want to have to buy a new one. The only fix I can do requires me to downgrade my machine lower than its current OS, (High Sierra 10.13.6). I plan on reinstalling MacOS to the original version it came with (Snow Leopard), but after downgrading, can I upgrade back again to Sierra?
Thanks
Jake
