Hi,

I am trying to install Slackware64 14.2 on my Late 2013 Mac Pro, AKA the trashcan Mac. However, everytime I try to boot the installation media off of my USB drive, the boot hangs after selecting the default huge.s kernel from the GRUB menu. It says it is loading the huge.s kernel and to please wait, however, it never proceeds beyond this point.

I have seen a couple other threads regarding Macs hanging at this point, but I didn't see any of them resolved, and most of them were of other Mac models.

I have tried setting nomodeset, however this doesn't change anything. I have also tried the KMS boot option as well with the same results.

Also, other distributions including those with the same kernel version as 14.2 do boot fine on my Mac Pro.

Any help would be greatly appreciated!

Okay, so not the same model, so may not be relevant. When installing on a white 2007ish MacBook a couple of weeks ago, I had a similar issue that was resolved by installing from a dvd (as opposed to a usb stick). I installed rEFInd first but unsure that's needed or not.

Thank you for the reply. Unfortunately, I don't have an external DVD drive to test that with. I did try Slackware-current, and it's installer is able to boot up fine, I even gave it a small partition to test an actual install, and it installed and runs fine too. However, I would prefer to use 14.2 if at all possible.

Does anyone else have suggestions as to what is causing this, or is there another way to start the installation media other than with the provided GRUB on an EFI system? Or, is there a way to make GRUB more verbose and actually display what it's doing, so I can see where it is actually hanging?
