The original post needs to be edited, because that is not the "Correct Answer" listed in it.
I have tried every suggestion made on this thread and none has worked.
I did the upgrade from SL to Lion the day after it was listed in iTunes.
My MBP is now acting like it is running Windows ME.
W.T.H.
It is not hardware or software. No 3rd party software booting in background, minimal services, not connected to a network even. It is so slow. I can start the mac and go make coffee and come back and the screen will still be booting. I have tried all applicable boot commands offered by Apple support as well, in an effort to fix any problems
I was hoping the update provided by apple the other day would fix this, but it does not.
I have since purchased 13 MacBook Airs with Lion pre installed on them, and they flat out fly. I manage over 60 Apple products in my company and also at home. This problem with the slow-booting MBP is the only one with the problem of slow boot and it is the only one that has had the upgrade via iTunes from SL to Lion
Dear Apple, please find a fix.
