Comment 7 for bug 774089

Hello all,

First of all Who thank you for the extensive information. I was a little sloppy in describing the condition but can confirm that I have the same symptons as you (first power on: flashing 'sleep' light, then loud beep, then a couple of power-ons where nothing happens, then booting seems to work fine.

* I have also tried wiping the hard disk clean and to freshly install MacOS X which __does not__ resolve this issue. So it seems that it is not limited to the hard disk.

@Colin: I am afraid this rules out getting any install logs from me, sorry I only read your post when my reinstall was already under way. I think that Canonical should maybe put a warning out somewhere prominently, if I had not performed the upgrade / install and was a Macbook Pro user, then I most certainly would appreciate being warned of this issue.

* I could also not find a firmware restore cd for the Macbook Pro 5,5.

discuss that topic, nobody seems to be able to find the appropriate cd.

* I will try to do the PRAM (Command-Alt/Option-P-R) and SMC (http://support.apple.com/kb/HT3964) reset, but have little hopes that this will solve the issues as Who described it wasn't working in the Apple store.

* Will then investigate firmware updates further - it seems really off that installing ubuntu would prompt something like a logic board replacement...
