A retrospective look at Mac OS X Snow Leopard
But back to my gut-reply', I wanted to be certain that my fond memories of Snow Leopard weren't just nostalgia. While I am confident when I say that Snow Leopard is the most stable version of Mac OS, I wanted to make sure its user interface was really the good user interface and experience I was remembering. So, after a few frustrating attempts at creating a virtual machine on my current iMac with Mac OS High Sierra, I decided to install Snow Leopard on a USB flash drive, and boot my 2009 MacBook Pro (yes, it's still alive & kicking) in Snow Leopard from that flash drive.
It seems to be a rather widespread conviction that it's been downhill for macOS for years now, and I can't say I disagree. Especially the current version looks like a touch-first operating system, but without a touchscreen. So many huge targets, lots of needless whitespace, things you have to swipe, buttons hidden until you mouse-over - it feels like Apple is trying to out-Windows 8 Windows 8.
