As a sometime mac diehard (iOS & Mac developer, ObjC enthusiast), I find it a little hard to imagine how anyone could continue paying through the nose for Apple's dreadful hardware at this point. A reasonable platform conservatism did encourage me to
consider another mac when my 2013 MB Pro outlived its usefulness, but only briefly.
Shame. Last time I used it (early 2018) I still found OS X to be have the best overall balance of good to bad things (no current OS is exactly 'good'). But the hardware is a complete deal-breaker.
