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..

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
months
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.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
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.

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.
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?

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.

Thank you for this info! So the only thing that we can do is wait...
sadly...
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.
i've contacted the author.. no reply received yet...
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.

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