Hello. I just bought a used Macbook Pro. It's an early 2015 model, if that makes a difference. Anyhow I'm reinstalling macOS. I notice there are two partitions (I think that is what it is called), one is the Mac SSD 256GB and the other is Recovery, like 650mb. I was wondering if I can, or should delete that partition. I mean, it is not a lot of space, but I don't know if it has anything in there from the previous owner or is it strictly a recovery thing. Please forgive me, I am a novice when it comes to this. Thank you in advance for your help and responses!
