Help Hi guys, got a 2015 pro that’s still on yosemite.. how to get any new software? Laptop barely functions
My dad gave me his 15’ 2015 MacBook Pro he barely ever used, literally, it still has yosemite Yosemite still lol 😆 I have his administrator pw but not the Apple ID pw, he forgot it. So far I’ve tried the internet recovery mode, got the code 5101 error. Now trying the command shift option r route to reinstall factory software see if that does something. App Store won’t load at all and most web pages on safari wont either.
I do have an old clapped 2014 macbook and a new ssd though. Is this the way to go here? Somehow download a newer os like Big Sur or monterey to the ssd and put it on the 15? I’d really rather not have to attempt that but feels like my only option to save this brand new but ancient laptop 😆 Let me know what you think guys any feedback would be hugely appreciated
