I'm a retired electrical engineer who has been working with PCs since 1981. I have used MS-DOS, Windows, Mac-OS, Linux Mint, Chrome OS & now Elementary OS. I am most experienced with Mac-OS from version 10.4 - 10.14 first on an iMac & then on a Mac-Mini. I eventually became annoyed with Apple's restrictions & tried to switch to a Chromebook, but could not get used to the way they handled files. So I finally installed Elementary OS on my 2014 Mac-Mini (Intel Core I5 @ 1.40GHZ,4GB RAM, 500Gb SSD). I think it's a great OS & it runs faster on my Mac-Mini than Mac-OS 10.14!!!
