Hi Linc
I have a question for you regarding consol log and "BOOT_TIME".
I have a similar problem with my MacAir which suddenly started booting slow, after some upgrade mid summer 2012 and I have not been able to crack the problem, even though I have tryed all advices like resetting SMC, NVRAM, chosing startup disk, creating a new user etc.
My problem is that everything is working perfectly, but for some trange reason it boots (apple logo and spinning cirkel) for approx. 2 1/2 - 3 min. until login sceen appears.
My question is; why is nothing registered to the log in that period of time, almost like saying everything is perfectly normal, example log:
17/01/13 09.12.05,971 shutdown: reboot by temp:
17/01/13 09.12.05,971 shutdown: SHUTDOWN_TIME: 1358410325 970914
17/01/13 09.12.35,000 bootlog: BOOT_TIME 1358410355 0
17/01/13 09.15.07,000 kernel: PMAP: PCID enabled
17/01/13 09.15.07,000 kernel: PMAP: Supervisor Mode Execute Protection enabled
17/01/13 09.15.07,000 kernel: Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64
As you can see its blank from 9.12.35 - 9.15.07. I can find several of these, and none shows more?
Hope you can give me some new advice, thanks!
