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. Shutdown both the MBP and iMac and then try rebooting the iMac as normal from its internal drive that now has Snow Leopard installed.I just installed a new HD 160G on a macbook pro, late 2008 to 2009.10.6.8) so that you know for sure it’ll boot the iMac fine

Reboot the MBP from the iMac drive and then upgrade Snow Leopard to the latest version (i.e.

Now install Snow Leopard onto the external drive (i.e.Boot the MBP from the Snow Leopard disc.Connect it to your Mid 2009 MBP with a FireWire cable (once connected it’ll be seen by the MBP as an external hard drive).Boot your iMac into Target Disk Mode by pressing and holding the T key as you startup.The only ways to get around this is to use another disc or do the following: It’s either one that belongs to another Mac or it’s a retail version that’s earlier than 10.6.6. My guess is that you’re not using the grey disc that shipped with your iMac. In other words, the Snow Leopard disc you’re trying to boot from contains a version of Snow Leopard that is earlier than version 10.6.6 (the earliest your iMac can support). And Yes, it’s trying to tell you something!Ī looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware. Upon checking after Monomeeth's answer I can add that the original Snow Leopard disc I am trying to boot from is indeed a retail version containing 10.6.3.

checked with Apple KB - About Mac startup tones and this pattern is not listed as an official form of communication.They beep as follows:īEEP BEEP BEEP BEEP BEEP BEEP and it continues until I power off. When I try to boot my Mac I get nothing but strange beeps.
