Hi,
I have made the EFI Upgrade to my early 2011 Macbook Pro (13'') - Mac OS X 10.7.2. The EFI version 2.3.
Now, every time I reboot or turn on the computer, it beeps like installing a new EFI, reboots three times and boots normaly.
I know this is normal when upgrading EFI, but it is happen every time I turn on or reboot.
Any tip? Do I need to restore the EFI?
Thanks!
MacBook Pro, Mac OS X (10.7.2)
You MUST be plugged in and charging the battery when the EFI is installing. Try that and see if it resolves you issue

It's plugged in. No mather if it's plugged or not I alway get the beep on boot. It seems that the EFI has not been installed correct, and is trying to do the instalation.
I have this issue too

Do you the original he installed? I have read that if you have altered the hd - replaced with a sad or another hd, the efi may not install at all. The solution would be to replace to the original hd and then install the efi update. Good luck!
It's the original HD. I'll do a hardware test to see if there's anything wrong with it.
