Help needed: Intel-based Mac dual boot testing

[Kamil Paral]

Hi folks,
if anyone has an Intel-based Mac (Macbook, Mac Mini) which could be used
for dual-boot testing with Fedora 41, that would be very helpful. We don't
have any such hardware at hand at the moment.

The testing instructions are here:
https://fedoraproject.org/wiki/QA:Testcase_dualboot_with_macOS

and the latest F41 release candidate (RC) can be found here:
https://lists.fedoraproject.org/archives/list/[e-mail]...

If anyone has such a device and can test dual-boot, please do and report
back either here, or submit the result to our test matrix:
https://fedoraproject.org/wiki/Test_Results:Current_Installation_Test#Miscel...

Thanks!

Yes. And already on it.

Okey-dokey, will keep you posted. Hope will manage to do it tonight
because it's already 8pm here in the UK and I am still at the stage of
reinstalling macOS.

Note Igor had some issues with this, as anaconda (and lsblk) seem to
see his macOS partitions as just a blob with the label 'cs_fvault2',
which to me indicates they're under Apple's "FileVault" encryption
thingy. The test case doesn't account for this at all.

Igor verified in macOS that filevault is set to 'disabled', but Neal or
Chris (I forget which) pointed out the filesystems might still be kept
in a sort of inactive filevault volume to allow for encryption to be
enabled again if desired.

From googling around it looks like we *could* potentially support
accessing and even maybe installing into a filevault setup, since
cryptsetup supports it since 2022, but anaconda/blivet maybe just don't
have support for this wired up the way they do for LUKS.

I'm not sure what we ought to do about this? Only support macOS dual
boot on systems on which filevault is completely and utterly inactive,
and document that in the test case? Lobby anaconda devs to use their
copious spare time to support filevault (hah)? Give up on macOS dual
boot as a supported/blocking case?

CCing devel@ as there may be more folks there with knowledge about
this.

[Snip]

Not supporting filevault installs would be analogous to what we do with 
BitLocker on the Windows side.

I would love to see us support both but I don't think there's the 
manpower to make it happen.

Hi Kamil,

Happy to test! I already submitted a success using `relval` with the Fedora
41 Beta 1.3 ISO.

Note: this was already discussed in Matrix at Fedora Quality.

Best,
Osama
