If your HDD is a secondary storage disk and your boot disk is SSD, I think that, by default, FileVault should only encrypt/decrypt the SSD boot disk.  If your HDD is your boot disk, I can understand why you wouldn't want to enable FileVault.

No, in Tahoe I will wait 8 hours to decrypt, it is not EFI on SSD or on HDD, it is whole macOS partition.

Open Core 1.0.8 adds an attribute to UEFI drivers that suppresses verbose output:

One use of this new attribute would be to silence the textual output of apfs_aligned.efi as discussed here.

I just installed macOS Catalina 10.15.7 on my HP EliteBook 850 G7 laptop, because I'm doing some testing that may benefit from the older macOS and the first MBP16,2 Macs were shipped with Catalina.  Not much of a surprise, but the installation was effortless and without any issues.  macOS detected the recently released 10.15.8 / Safari updates and applied them without issues.  The credit for this goes to the Open Core and Kext Devs who have continue to maintain backward compatibility.  With exactly the same EFI, this laptop boots Catalina through Tahoe.

 

Thank you OC Devs and all the supporting Devs who continue to provide us with the essential Kexts.  You have made our hackintosh journeys possible.

 

Posting this with Safari Version 15.6.1 (15613.3.9.1.16, 15613) in Catalina 10.15.8 and it still works!

EDIT: I'm using the same version of itlwm.kext (2.3.0) and Heliport (1.5.0) to enable Intel Wi-Fi across the different versions of macOS.
