Initial experiences with Snow Leopard weren’t as blissful as more recent commentary remembers. The troubled rollout of MobileMe, iCloud’s precursor, was still an open wound. Soon after release, a major bug was discovered in Snow Leopard that would cause the home directories of guest accounts to be wiped completely. The issue was prevalent enough that Apple publicly responded and later issued an update, 10.6.2, to address the problem.
Sure, Snow Leopard had it’s problems too as almost all macOS up to this point. So I’m still not subscribed to this Apple software quality is in decline bullshit. Most of it just nostalgia, for example: I remember a lot of kernel panics on my old white MacBook back when it was running Tiger but I had not seen them since Lion.
