I just purchased a mid 2009 macbook pro so I can use Apple products for all my computer needs and only use my dell laptop to program my digital ham radios. That being said, my new to me mid 2009 macbook pro is only supported to El Capitan, however i see there is a patch tool that can be used to make High Sierra install on it. I am debating if I should attempt to do the patched install or leave the laptop alone running El Capitan since it is running perfect as it is. Just wondering what people's thoughts on this are?
