So far does 10.8.4 fix the slow shutdown times?
Do you use your Mac for real work, or just for startup/shutdown benchmarks?

FFS, let's not start a shut down vs sleep argument again. You never ever in your life shut down your Mac? Good for you! That doesn't mean shutdown times should be that long. Period!

Those people who don't care about shutdown times, and leave their Macs in a sleep mode all day, probably don't take the Macs out of their houses. They also aren't aware that even if the Mac is encrypted with FileVault2, if a thief gets hold of the Mac in sleep mode, it is not as secure as if it were stolen when totally shut down.

Given this fact, those people who rather pompously brushed aside those who value fast-shutdown times, need to reconsider their stance.

Fast shutdown times encourage me to shut down when I'm not using it since it takes minimal time to start up and shutdown.

But when that process takes more time, the lazy approach is to just leave it in sleep mode, which leaves your Mac more vulnerable to data theft it is stolen while in sleep mode.

To those who lazily just put their Macs to sleep -- and, in their ignorance, BRAG about it -- educate yourself and do this google search:

mac vulnerable sleep shutdown filevault 2

And whilst Apple are at it fixing ML 10.8.4, they might address this security issue that sleeping Macs have.

Well, I care about the shutdown time because I often reboot to Boot Camp because OSX is still lacking in some aspects. :cool:

Come on, not everyone uses Macs the same way as you do. :mad:

And, even if it may not bother you, this is still more of a bug.
Regardless of the purpose which may have been to prevent iCloud sync issues or what not.
