MacBook Pro 2019 Setup

Setting up the new machine. I found a few tips on brightness, dark mode and notifications from this Digital Trends article, but I had a few other things I wanted to tweak.

Fixing the AppleTV app red badge notification:
I quickly noticed a red “1” badge above the AppleTV app. This badge would not go away even after launching the AppleTV app. I had to delete some .prefs files and reboot using instructions found on Apple support: Specifically, deleting ~/Library/Preferences/ and ~/Library/Preferences/ worked for me. Don’t worry, the files are recreated when you launch the app again. That allowed me to then configure the badge notifications in the System Preferences.

AutoBoot on lid open:
AutoBoot on lid open is a neat feature, but can be problematic when wanting to clean your keyboard and magic pad area. Disabling AutoBoot is just a quick terminal command can make all the difference.

Disable AutoBoot on lid open on MacBook Pro 2019:

sudo nvram AutoBoot=%00

Return to default:

sudo nvram AutoBoot=%03

During this research I also discovered a similar command to bring back the startup chime.

Enable startup chime on newer Macs:

sudo nvram StartupMute=%00

Disable startup chime:

sudo nvram StartupMute=%01
