I've read enough of buggy behaviors on MacOS that I'm not sure I'd buy a Mac today. Wasn't their new filesystem a giant mess? Even the shiny new M1 had SSD wear problems in the beginning, hmm, great QA, guys!
No? It was a very smooth rollout (even more impressive if you consider it also rolled out to all iOS devices). I can’t think of a similarly large technical change that went so smoothly.
There are things to complain about with the software quality of Macs, but the file system isn’t one of them in my opinion.
The Longhorn project did include an attempt at doing a fancy new filesystem, more database flavoured; I'm not sure if they ever finalized the feature list, much less got it working, and now everything ships with NTFS which is slow but reliable.
