alt Hacker NewsI don't agree, as someone who lived that era. Snow Leopard was the best OS X release in terms of performance, made immediately apparent by the disastrous release of 10.7 Lion and several years beyond.
You have to remember that 10.5 was a bad and slow release. 10.6 cleaned that up, and gave you a lot of storage space back alongside the fixes and improvements.
I lived that era too, and Snow Leopard was no less buggy than any other release. What actually happened is that engineers had been shifted over to iOS, which delayed Leopard. By the time of Snow Leopard, to put a positive spin on that lack of resources, Snow Leopard was a "no new features" release...even though it actually did receive new features as well as new bugs.
There was even an infamous data loss bug involving guest accounts (https://www.reuters.com/article/lifestyle/snow-leopard-bug-d...)! But people have forgotten about that and only remember the marketing now.
