It might also be worth working out a fix for anyone with their computer out-of-warranty. To this end the following debug information might also be useful
* I could not run the latest firmware update utility because it told me 'my computer does not need the update' * This message persisted even after a complete re-install of OS X/redownload of the firmware utility * I could not find a firmware recovery CD for the macbook pro 5,5 (http://support.apple.com/kb/HT2213) (could we modify one of these to use the latest firmware for 5,5?) * More annoyingly, I couldn't get the computer in to the right mode to reflash anyway. The Apple manual says " # Turn on the computer and continue holding the Power button. The sleep LED will blink rapidly, then slowly, then rapidly (3 quick blinks, 3 slow blinks, 3 quick blinks). On Macs that don't have a sleep LED, tones are used instead. Hold down the power button until you hear 3 long tones, then 3 short tones, then 3 long tones. On Macs that use a tray-load optical drive, the tray will open to allow the Restoration CD to be inserted. # Insert the Firmware Restoration CD while the lights are blinking or tones sounding, then release the Power button. A long tone is played once the recovery process has started." However I could not get the '3-quick, 3-long, 3-quick' pattern to occur. I did not try this as many times as I should have done to be certain. I was using the firmware restore cd 1.9, which doesn't list 5,5, but its list is wrong anyway: it incorrectly lists 5,1 as a 2010 model when it is really the mid 2009 17" (http://support.apple.com/kb/ht4132 vs http://support.apple.com/kb/DL1320) Here are some useful debug docs that don't jump out of Google as easily as I'd have liked: http://support.apple.com/kb/HT2674 - bootup sequence and status lights. I can't correlate anything on their to our problem http://support.apple.com/kb/HT1533 - key combos at startup -- You received this bug notification because you are a member of Mactel Support, which is a direct subscriber. https://bugs.launchpad.net/bugs/774089 Title: Booting fails 3 times, works every fourth time after new install of Natty Narwhal amd64 on Macbook Pro Status in Ubuntu: Confirmed Bug description: Dear all, I am experiencing a severe problem after a new install of Natty Narwhal on my Macbook Pro last night: The install worked fine, but after reboot nothing came up except fo a black screen. After forcing the machine off and on multiple times I was able to bring up the rEFIt boot menu by pressing and holding the 'Alt' (or Option) key and I can then boot into MacOSX or Ubuntu without a problem. After restarting / powering off I then have to turn the computer on / off the same number of times (3 or 4, I don't remember exactly) where nothing happens until it works again. I am using a MacbookPro 5,5 (13.3 Inch). My harddisk is setup as follows: 200MB Partition for EFI 20GB Partition for OSX 18.6 GB Partition for / (ext4) 108.49 GB Partition for /home (ext4) 1.86 GB Partition for swap Other people also seem to experience the same issue: http://ubuntuforums.org/showthread.php?p=10743955&posted=1#post10743955 This is a pretty big problem for me, so your help is very much appreciated.
