My MacBook Pro has gone from 34 seconds from pressing the power button to the login screen, to 58 seconds in Lion.
Anyone else experience slow boot up time?
Running a 2007 MacBook Pro with a 500GB WD 5200RPM drive if someone wants to compare.
Hi,
I had the some problem with my Macbook Air 4GB/SSD - time boot problem after upgrade on 20.7. to Lion (from power on switch 4-5 minutes till login window comes, Snow Leopard before about 18 sec) and I spend two days to find the solution - I try all what you wrote here, all what the others write on internet, but nothing help.
After many hours of checking I found temporary solution (because this is real serious bug inside Lion) as following :
Go to the System preferences-Users and Groups and just delete all what is under settings for Network Account Server till comes back "Join" button in UsersxGroups screen.
After restart your computer and all is WORKING WELL ! and your notebook will start fast again (14-16 seconds).
OK, you will lost the usage of Network Account Server future, but this bug is so big, that I am sure Apple will fix it very fast and after you can Join back to Network Account Server.
You can see more information here on Apple Support Communities uder article "slow boot after upgrading".
I really spend two days with analyzation boot procedure of Lion, network analyze and this is the reason for BOOT TIME problem - some serious bug inside Lion and Network Account Server, and not only with time boot, there are more problems there...time boot delay is only "side" efect of some other errors.
Try this and let me know, I am sure, you will be suprise as fast will start your Lion after you delete all under Network Account Server settings... This is serious BUG, but hopefully this will solve your problem with starting time till upgrade from Apple come.
