Catalina and T2 Chip Question

[canyonlight]

I am running a new Mac Pro (2019) that has the T2 security chip.

I am running macOS Catalina 10.15.5, and SuperDuper! 3.3.1 (v121).

My question is whether or not I will be able to boot the Mac Pro from the external hard drive where the SuperDuper! backup is located - connected via Thunderbolt.

I understand from another software vendor (SoftRaid) that to be able to boot the Mac Pro with the T2 security chip from an external hard drive that I will have to restart the Mac Pro into Recovery Mode and disable secure boot.

Do you know anything about this?

Thanks,

Stan

You have to turn on the ability to boot from external devices in the security utility (in Recovery), but otherwise it should boot fine. (Note that 10.15.5 has other issues; see http://www.shirt-pocket.blog).

Thanks for the quick reply Dave. Catalina is certainly presenting its challenges.

Indeed. As they say, "interesting times".
