I was starting to get issues with a macbook from 2012 (specifically homebrew / xcode) when I upgraded. I'm going to be honest: Having a powerhouse of a machine for 10 years before it becomes obsolete, I'm not going to complain for one second. Got myself a new macbook, and it runs like the wind. Works seamlessly with all the tools I need in an environment where we rely on gfortran / gcc, and a lot of my coworkers use Linux.

To be fair: Part of the reason I waited for so long before upgrading was that I was waiting for them to ditch the butterfly keyboard / touchbar, and get some ports back into the machine. Once they did that I was sold. My only issue with macbooks would be the absurd price for an adequate amount of RAM, but as far as having a good computer, once it's paid for it's fantastic.
