I've a 2015 MBP, which I've not used for years. I need it and forgot the password. The router was changed, so it's not connected to the internet and apparently I can't update it. The ⌘ Command R shortcut to enter recovery mode seems not to work - I tried both holding before restart, pressing it during restart, pressing it many times, etc. and it doesn't work.
I'm considering taking the hard drive out, buying an encase and trying to reset the password from my current M1 MBP but not sure what's the path to follow here.
What should I do?
