#218 rEFIt on MBP late 2011

John Doe

Hi! I've tried to install rEFIt on my MacBook Pro late 2011 but i've had no success, i think that there is something in the MBP firmware that block the installation...

Any suggestion or prove that i'm wrong is welcome..

Sorry for my poor english ;-)

    i found here the info why the macbook late 2011 not work
    18:23 <Branes> Apple changed the UEFI structure with the newest MacBook Pro's and the latest
    iMac refresh.
    18:23 <Branes> As such, neither rEFIt nor grub (nor grub+) will work.
    18:25 <Branes> The change is a little over five weeks old.
    18:26 <Branes> Until the rEFIt people wake up and fix the limitation, it won't work at all
    with the newest EFI firmware that's been shipping in all machines for just over
    a month.
    18:26 <Branes> rf you just bought it, then it has the new UEFI structure.
    18:28 <Branes> Apple use 'Protected GPT' which is a dogs' breakfast.
    18:30 <Branes> The main problem with pGPT is twofold: 1) no linux loader knows how to deal
    with it, and 2) it is no better than MBR in that you are limited to four
    partitions ... and Apple already use three, one for EFI, one for the main OSX volume,
    and a third for the Recovery partition.
    18:34 <Branes> Best be thankful, then, that you bought a new machine now, and not in four
    18:35 <klausa> What will they change in 4 months ?
    18:35 <Branes> klausa: They adopt the changes to UEFI proposed by Microsoft.
    18:35 <Branes> Machines then will *only* be able to boot Mac OS X, iOS Desktop, or
    Windows 7 -- the hardware will not aloow any other OS.

    I repro this bug on my MBP8,3 with OSX Lion.

    1) install refit
    2) reboot several times
    3) observe every other boot, spins forever, the only way past is to power down, then it will boot into normal mode not refit.

    I do recommend that you contact the author of rEFIt and offer donations.

    If the author of this project would be sure that with updates rEFIt will work, i'll surely donate something to help him..

    There is an IRC channel of rEFIt?

    Can you say a bit more about what you're trying to boot with rEFIt and when the installation breaks?

    I got rEFIt to work on a MacBook Pro 8,2. I don't know if there is any difference between the 8,2 and 8,3 models beyond screen size, as they came out at the same time.

    This is a shameless plug, but I wrote a guide about using rEFIt on a MBP8,2 here: http://jeriko0x7e.blogspot.com/2011/12/triple-booting-os-x-lion-ubuntu-and.html
    Depending on what you're trying to do, this guide could be helpful.

    The list at http://support.apple.com/kb/HT1237 says that all the 2011 MacBook Pros use the same EFI Boot ROM version MBP81.0047.B24 (EFI 2.3)

    Maybe the problem is hardware dependent - type of graphics or type or size of hard drive? Anything connected to USB or FireWire or Thunderbolt?

    Use the bless command to manually bless refit.efi. Or try blessing shell.efi to see if that will show up.

    jeriko0x7e's guide suggests putting rEFIt on a separate partition. This will let you select either rEFIt or Mac OS X when you press the option key at startup, incase rEFIt doesn't work.

    has anyone with had anymore luck with a solution to this?

    heres what ive got:
    MacBookPro8,3, Intel Core i7, 2.3 GHz, 4 GB
    Boot ROM Version: MBP81.0047.B27
    SMC Version (system): 1.70f5

    report from rEFIt partition inspector:

    *** Report for internal hard disk ***

    Current GPT partition table:
    # Start LBA End LBA Type
    1 40 409639 EFI System (FAT)
    2 409640 1463879591 Mac OS X HFS+
    3 1463879592 1465149127 Mac OS X Boot

    Current MBR partition table:
    # A Start LBA End LBA Type
    1 1 1465149167 ee EFI Protective

    MBR contents:
    Boot Code: None

    Partition at LBA 40:
    Boot Code: None (Non-system disk message)
    File System: FAT32
    Listed in GPT as partition 1, type EFI System (FAT)

    Partition at LBA 409640:
    Boot Code: None
    File System: HFS Extended (HFS+)
    Listed in GPT as partition 2, type Mac OS X HFS+

    Partition at LBA 1463879592:
    Boot Code: None
    File System: HFS Extended (HFS+)
    Listed in GPT as partition 3, type Mac OS X Boot

    and i get the same thing. i install, reboot comes up to Apple login screen, reboot, hangs at loading screen, force power off, power on, Apple login screen. nvr a refit screen. ANYONE have any idea what in the world is going on? i desperately want to be able to run refit on this mac. =\

    misterogwannabe, have you tried the various suggestions already listed on this page? Have you tried installing rEFIt on a separate partition? rEFIt is working just fine for me.

    I was having this same issue but fixed it by running the "Repair Disk Permissions" function in the Disk Utility tool.
