My FIRST Crash I spent the previous day installing EOS as a dual boot on my MacBook Pro. Its was working great. I shutdown and restarted several times booting into macOS or EOS. No problems... Today when I booted up, and selected EOS, logged in, and that's when the problems started. The login seemed to go okay, except that I didn't have the top menu bar or the bottom launch bar, just my wallpaper. I did a hard shutdown and rebooted with the same result. Shutdown again, rebooted but this time I didn't get the the rEFInd boot menu to select either macOS, EOS or even my recovery drive. I'm thinking that my EFI partition had been corrupted. I had no choice to reinstall macOS, partition my drive and reinstall EOS. I'm back up and running pondering what went wrong. So what had I done. 1. Updated all the apps through the App Store. 2. Installed Chromium through the App Store. 3. Added Dashlane to Chromium (My password manager) 4. Installed and activated Express VPN through the CLI (using my VPN account) 5. Installed Evolution email and set up my iCloud mail account. 6. Tried to setup Calendar with my iCloud account (no luck) I had followed the install instruction from GitHub and the only thing I did different was to install rEFInd from my macOS desktop rather than from the macOS recovery desktop. Any thoughts on what may have gone wrong?
