How do you tell how many cycles you've burned?

System Menu > About This Mac. Click on More Info, then look for the "Power" section. It should show battery status, including Cycle Count.

2011 2.2 is my mbp, but i'm not going to update. Probably would sell it before it reach 500 cycle mark

My 2010 i5 15" Macbook Pro has 1100 cycles and the battery seems as strong as ever.

Update worked fine.

Cheers, good to know.
I also updated couple of days ago without a glitch.

Firmware Upgrade

I installed this upgrade on my mid 2012 rMBP, all went well computer worked fine. I shutdown the system and that was that. My machine will now have to go back to Apple.

That would be a different firmware update than the one in the thread. Unfortunately there is a risk in updating firmware that if something goes wrong, the device can become useless.

Having gone through 15-20 firmware updates in my time, I think this might be a PEBKAC issue.

1000 cycles? How on earth does a 2011 MacBook Pro reach 1000 cycles that fast? Crazy! Must be that 0.000001% of the Apple-owning population that reaches such a number.

When I was in school I was using 2-3 full cycles a day, so a thousand cycles in a year was easy!
