It should be the first partition on the drive for the best results if not, that may be the reason for the 15s delay. Speaking of that reserved bios partition, where did you put it ? From your text it seems to be at the end of the drive. Note I may be wrong on that last point, and you should check what partition scheme is used on your drive with sudo parted -list.

that you made a Legacy install on GPT, as hinted on by you saying you have "a 1MB reserved bios partition" (which is necessary for Legacy on GPT). It assumes that your hard drive is already formatted as GPT, i.e. If you dont want to reinstall, the procedure I gave above can convert your install to EFI mode. If you are okay with reinstalling, follow the instructions by CaptainKirksChair, they are perfect (and they will give you a recovery macOS partition, which can always be useful, and a backup of the firmware will be available on the EFI partition, which can also be useful).

When the Mint install finishes, your hard drive will be setup to something the Apple hardware requires and Mint can take full advantage of. If you forget the step above, the system won't boot. The screen shot above is NOT the same system as the iMac 9.1 - it's just an example. At the bottom of the Installation Type screen, be sure to choose the EFI partition as the Device for boot loader installation as shown below: When you go through the install process, remember to choose Something Else. The 320GB hard drive on my iMac 9.1 looks like this:Įxit Gparted and install Mint. In the empty partition, create your Mint root, home, and swap partitions.

Boot into the Mint LiveUSB and use Gparted and remove the Mac OS and data partition. When you are finished, you'll have an EFI partition, an OS and data space, and a recovery space. The macOS install process will create a GPT partition table and the necessary Mac partitions. It doesn't matter because everything is going to get removed later except the EFI partition.

The recommended way is to install the macOS from the DVD that came with the computer. You need to create an EFI partition before you do anything. Sun 10:50 amIf I were to install mint again, how do I keep from installing it in legacy mode? I have another macbook pro I will be installing 18.3. Make a note of the name of that EFI partition (in the following I'm going to assume it's /dev/sda2) and the / partition (in the following I'm going to assume it's /dev/sda3)Ĥ ) mount the / partition at /mnt and the EFI partition at /mnt/boot/efi :

* stay in Legacy mode, and use these instructions to cut the 30s delayġ ) boot your linux live USB in EFI mode (by pressing alt/option during boot and choosing the option "EFI Boot"), open gparted, resize the / partition to leave about 50MB freeĢ ) make an EFI partition in this free space you just made : make a fat32 partition and set the "boot" and "esp" flags. So everytime you boot, the firmware looks for an EFI bootloader hopelessly, until it gives up (after 30s) and boots in Legacy mode.

What happens is that you installed Linux in Legacy mode, that's why you get "EFI variables are not supported on this system".īut the firmware is still set to boot in EFI mode (the native booting mode for Macs) by default. It's not a problem of grub, it's before that, at the firmware level.

I'm glad I can boot into mint, but it would awesome if the mac would start mint immediately. when I went to run it, it came back with: EFI varibles are not supported on this system. what is controlling the boot, the OS firmware or Linux? I installed efibootmgr. all worked perfectly.Ĭan anyone tell me what's going on during the boot process to cause it to delay that way? I've restarted and powered down and restarted, every time it repeats the with same method. then, went to a dark screen again and then it came up to the desktop with the chime.

it then went dark screen and the mint logo appeared with the small dot timer below it. the apple chime sounded, and it went to a grey screen for about 24 seconds. when it came time to reboot, it got a little strange. I partitioned the disk as follows: / partition, /home partition, a swap partition and a 1MB reserved bios partition. I just installed a new HD 160G on a macbook pro, late 2008 to 2009.
