Snow Leopard is the gateway to update your Mac to a newer operating system via Apple Purchases. Having seen the negative reviews, I thought I'd give it a go and see what happens. Nothing to lose.

Snow Leopard is fondly remembered by many longtime Mac users, both because it was a remarkably refined release and because it was the last version produced before Apple really started porting iOS features over to the Mac.

Some of those people will be using Macs that aren't compatible with newer versions of OS X, and others will be sticking around because of their personal preferences (or spite, or stubbornness). Either way, if you're still running 10.6, fire up your software updaters for the first time in years because Apple has just issued a small update to 'ensure future compatibility with the Mac App Store.'

This doesn't mean that Snow Leopard is suddenly supported again. Rather, it allows Apple to continue offering modern OS X versions to the Snow Leopard users whose Macs can run newer versions. You can upgrade directly from Snow Leopard to any newer version of OS X, including the current El Capitan, and the Mac App Store is the main delivery method for those upgrades.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.
