Installer Hangs on MacBook Pro [Video showing problem]

I am trying to install Slackware64 14.1 on my Mid 2009 MBP (5,5).

I downloaded the ISO, and burned it to my USB using Universal USB Installer on a Windows 7 machine. When I boot into the USB on my MBP, I get greeted with a GRUB welcome screen, then a prompt to choose mode, then it says to wait, then it hangs.

I let it sit for an hour and it never gets to the select language, keyboard and login as root prompts.

I have been using Slackware on and off since 2010. I have always used SW on PCs (both laptops and desktops), but I have never tried it on any Mac.

I recorded what I was experiencing and uploaded it to YouTube

I DO NOT wish to use refit/refind, I simply want to hold the Option Key at boot and choose "Linux", and have it boot into Slackware

First, thanks you for posting this video, that makes thing very clear.

To burn the ISO image on an USB stick, I suggest that you try Rufus instead of Universal USB installer, then please tell us if you get the same results. I've been successful using that for Slint installers, (though I couldn't make it recognized as bootable on a Mac yet, but that's probably for other reasons) and this is the tool recommended for Windows users on the Syslinux mailing list.

PS of course choose UEFI/GPT, not UEFI/MBR.

I was never able to get Linux on the metal of my 2009 17" the dual graphics seem to be the issue

Did it hang or was it just the display that froze up? (I notice the GRUB cursor isn't blinking, but do not know if this is normal.)

On my MBP Early 2011 8.3, using ELILO to boot the USB, I found it was just the display freezing up. I added nomodeset to the command line options and the installer worked properly. I don't know if it might be something similar for your MBP.

As for not using refit/refind, you could create a small FAT32 partition, create an EFI/BOOT directory and place the kernel/bootloader (whichever works better for your MBP) in there, renamed to BOOTX64.EFI. The Macbook EFI firmware doesn't recognise linux partitions. There may be other ways to do this, but this was the approach I used.

Sorry for the delay in getting back to you guys. I just finished Finals Week, so now I have more time for the Internet .


Ok, So I made another USB Disk using Rufus. I get the same result. However, I did play around with the usb-and-pxe-installers/ and put the USB installer on a Memory Card (My two USB ports are too close together to use two USBs at the same time). I also don't have a optical drive, I have a 1TB HDD there instead.

My thinking was that I could use the Memory card to get into Setup, then select the USB as the "source dvd" and have it install from there. And then I'd be on my merry way. However I run into some problems.

I tried to change the vga=normal to 773 and ask, and I couldn't tell if I was doing it right(not featured in video). It looks like it it doing this weird split and overlap thing. but I can select my keyboard layout, login as root, even start setup, but i just can't read anything.

Also, if someone could explain what to use of format the predefined partition My Macintosh SSD Partition layout (yes, I know there is nothing in my Windows partition, there WAS, but it was killed when I followed some old guides on the Internet, I wanna get this going, I will reinstall Windows and then SW later)

I am also not sure on what partition I should install the boot loader.

I didn't realize how much more difficult this would be on a Mac vs a PC, but it'll be worth it.

I think it should be nomodeset, not nomemset, that you should try.

Triple booting OS X, Linux and Windows on an older Mac is a bit of a pain. My partition setup is Mac(HFS+), Linux(EXT4), then Windows(NTFS). The partition type doesn't really matter. Some websites say the order matters, I don't know if it does but I decided to play it safe.

Booting with EFI requires an additional FAT32 partition, either on a USB stick or on your second hard drive. The pathname of the bootloader/EFI Stub kernel should be /EFI/BOOT/BOOTX64.EFI. This is probably the best way to do it as long as everything on your Mac works properly in Linux though it might be harder to set up.

Booting via emulated BIOS can be done by going through Windows first. AlienBob's instructions will work. I don't recommend this method if you are installing Windows 8 unless there is no other choice.
