Firmware passwords of all kinds disabled for Silicon-chip Macs
I knew that firmware locks sent via MDM command didn’t work on the new Silicon-chip Macs, but I didn’t realize that the manual setting of a firmware password was also disabled (makes sense, since the two are probably linked in terms of how they’re implemented or the firmware mechanisms they use).

Semi-automating profile installation in Big Sur

Rolling back versions in Munki and using blocking applications arrays
Downgrading software in Munki can be a bit tricky. One of the tricks you can use is to remove the higher version number from your Munki repo, and replace an .app bundle–based installs array with a binary-based one.

How to check the Carbon Black version installed
Update Thanks to Clay Haynes for pointing out you can get the version more easily by running /Applications/VMware\ Carbon\ Black\ EDR.app/Contents/MacOS/CbOsxSensorService -v Back story In Carbon Black 6.3.0 and 7.0.1, it isn’t super obvious how to check for the version installed.

2 June, 2021 Update Special shoutout to Armin Briegel for pointing out that the zsh version runs just fine if you use a different variable name from USERNAME. I’ve tried it with USERACCOUNT instead, and I’ve confirmed it works fine with zsh. Original Post Apple is moving toward making zsh the default shell instead of…
