Mavericks Forever. This reminded me that I still have my old MacBook Pro from late 2013, which came with Mavericks pre-installed. I ended up my Apple journey with Mojave running on a Macbook 12”, which has always been my preferred version of OSX, and one of the best laptop I used to use over the years. Now the MBP is waiting for Ubuntu to upgrade thousand of packages (I haven’t used it for two years now) before I perform a do-release-upgrade.
