asklemmy is not a support channel. I haven't found any macOS related support channel on lemmy and while Im searching the internet for macOS forums, Id like to know if you have any recommendation. Some questions I have are:

how to reinstall an OCLP unsupported macOS security copy from a usb stick to the original partition

Would it make sense to ask an apple vendor to change the notebook's keyboard? It's Portuguese, I want an American keyboard)

Where do I get more memory, a new battery and can I change both things at home or is it all glued together and the only way to do it is through a vendor?
