Changing security setting on M1 MacBook Pro 16" running macOS 12.6.7 Situation as in title. So I restart keeping the Start button depressed until the Recovery utility asks me for a startup disk and an admin user. I only have the built in boot disk and an external clone, so I select the built in boot disk and login with an admin user. Then I select Security Settings in the system bar. I am then prompted to select the the disk on which the security setting will be change. Only the one disk is displayed. It seems to be the boot disk ... BUT underneath the name, Macintosh HD, there appears "macOS 13.4.1", not "macOS 12.6.7"! Where did 13.4.1 come from, and why is there no choice 12.6.7? Might it be my configuration of Update, namely, download but do not install? I see that security has been reduced, which is what I wanted (i.e., to allow apps by developers recognized by Apple to load things at boot time). Nevertheless, when I then restart, the app, OWC SoftRAID 7.5, is still telling me that I need to go to Security & Privacy and click the botton "system software from Other World Computing to load", which, however, doesn't appear. (The fix, according to OWC, is to set the system security, as described above.)

No Option to allow booting from external drive. Macbook Air M2, 2022 I have tried just about everything. But in the picture below, the bottom of half of it that gives the option to allow booting from an external drive doesn't even exist. It just isn't there at all. And as far as the Startup Security Utility options goes, I only get to choose from "full security" or reduced security. So I have found nothing that addresses this issue. Please help. Thanks in advance.

Your 2017 model-year MacBook Pro does not have a T2 chip. T2 chip was introduced in the 2018 model-year.

When attempting to change these settings on a Mac that does NOT have a T2 chip, settings you can not change are already allowed.

No more excuses -- Get to work! ;-)
