The biggest hangups I had with using Mavericks in 2022 was the web experience. Mavericks on the other hand offered a much more modern feeling experience despite being only a year older. While Mountain Lion was fun, it had some weird internet issues when trying to connect to my phone’s hotspot and I couldn’t really use it for much.
A couple weeks back I posted an article called called Let’s See What We Can Do with an Old Mac, and in it we looked at a couple of older versions of OS X - namely 10.9 Mavericks, and 10.8 Mountain Lion.
