I thankfully don't use it everyday, but Mac and literally everything on Mac (even the terminal started crashing on resize towards the end of the time I used it every day). Over time, I started keeping a note where I put every bug, missing feature, malicious feature, performance issue, driver issue I had with my 2 different MacBooks day to day, and it's loooong. I'll probably never organize it unless I'm forced to use…
Compared to Windows it's an absolute dream. I left Windows because it was a mess and applications constantly crashed and also the OS crashed and the multitasking is thoroughly crap. I have a Windows machine and every now and then I think "maybe it's all better now", and I give it a try and instantly the same crashy problems and really bad multitasking.
