Back in my day, Apple never used to have OS upgrade quality issues. Why have they abandoned pros? Ah, too true. I remember the golden days, back in Yosemite, OS X East Bay, OS X Delayed BART train, 10.6, 10.5, 10.4.8, 10.3, Mac OS X Puma, Mac OS X Llama, Mac OS X Rabid Kitten Beta 3, System 8, System 7.5.3 revision 2, System 7.blergh, System 6, PowerBook 5300 On Fire, Apple III Drop It On A Table Until It Starts Working… no problems whatsoever. Everything "just worked," back when Steve Jobs was with us and I used my Mac Classic at school which I went to and from uphill in the snow both ways even in September, until the sad day when Gibson bought Studio Vision Pro and killed Christmas forever and the End Times were nigh.
