Unable to boot on Thunderbolt-equipped Macs

[bobrost]

Apple Macintoshes with Thunderbolt ports (2011 and later models) are unable to boot Haiku.

Using ReFit as the boot manager, selecting the Haiku partition results in either a hung "other os" boot icon, or a black screen with white text "Unable to find boot device" (or similar). This applies to both my MacBook laptop and my Mac Mini desktop, whether attempting to boot from USB stick, CD, or internal disk partition.

This has been true for all alpha versions of Haiku I have tried, and is not new with alpha 4.

For reference, this was an issue with all Linux distros as well when these machines were first released, but a quick internet search shows that Linux now has either a workaround or a full solution. I expect the issue stems from changes in the OpenFirmware disk controller.

Is this still an issue?

rEFIt hasn't been updated since 2010. Try rEFInd instead. ​http://www.rodsbooks.com/refind/

I guess EFI booting should be used on these machines anyway?

I've tried booting on a mac mini 2012 and mac mini 2014 with a 64bit efi version.

I'm wondering if this is the issue I am encountering. I will try using refind to boot haiku and see if that works around it

(for reference, for both of those machines the kernel boot icon never lights up, but the image is drawn correctly)
