    I just got a 2018 MacBook Pro with the new T2 chip. I'm passing information this along as a general FYI... When booting up my new MBP, the keyboard backlight and the Touch bar wouldn't turn on for the login screen. No Touch Bar, so I can't adjust the keyboard backlight. I find this annoying...

    iMac Pro Slow Boot - FileVault?

    I picked up a refurbished iMac Pro recently. I set it up and have FileVault running. I noticed when it starts up it takes a very long time (40 seconds +) after I hit the login screen (the one with the icons) before the Bluetooth mouse connects. The loading also feels a little glitchy and the...

    Hi there. I own an old iMac but don't really use it that often. One day after attempting to start it up again, instead of the typical boot, I was greeted with a blinking folder with a question mark. As of a month ago, my iMac worked just fine. I had a relative login as a guest on it but I don't...

    Slow boot (black screen before Apple logo) after HFS+ to APFS conversion of external boot SSD USB-C

    Hello! :-) I have an iMac 5K 2017 3.4 GHz and was running High Sierra with an external SSD disk (WD My Passport SSD 512GB) as boot disk. The macOS High Sierra allowed me to skip the conversion from HFS+ to APFS. The latter caused slow boot times last year. I was running fine with that system...
