Hello Mac people! New here, new to Macs (but I have an iPhone 7) and this is my first post. I tried searching around for an answer online but I didn't seem to get a clear one. I have an older MacBook Pro that has XCode. Got it from a friend and he left it on there since he knows I'm studying computer science--he had messed with it a little bit. I have a bit of history in HTML/CSS but XCode, apps and stuff is still new. I see that I can't go beyond High Sierra on this Mac but it's cool. Just wondering how XCode works, if it'll still work in High Sierra and for how long. I did a security update and it seems that it's still working when I open it. Just wanted to say hi and make my first post on here. Peace
