False positive on encryption check for Fusion Drives

[dayglojesus]

There is anecdotal evidence that this app will refuse to run on Fusion drives because it falsely detects the "drive" is already encrypted.

How are you doing the detection of an encrypted drive? Are you using "fdesetup status" or some other means?

[dayglojesus]

Not fdesetup. It uses some CoreFoundation functions which worked in all my testing until today.

I don't suppose you have any unencrypted fusion drives you can try launching this app on?

[rtrouton]

I don't, but it should be possible to create one in a VMware Fusion VM using these instructions:

I tested my FileVault 2 check scripts against a homebrew Fusion drive inside an OS X VM running in Fusion. It was a good simulator and gave me the same results as an actual Apple-provided Fusion drive.

That sounds promising. Unfortunately, it will be at least a week before I can test and patch this. I will see if any of the team can give it a whirl.

In the meantime, if you have time to test it, please let me know how it goes.

Thanks, Rich!

Thanks for the suggestion @rtrouton. This issue should be fixed now.
