ok, embarrassingly, now i'm going to sound like the mac newbie i am...
what's the reason to keep yr mac desk/laptop on/asleep all the time instead of shutting down? boot times are quick compared with pc...![]()
I guess you could think of the question the other way around:- why would you wait 30 seconds for it to boot when you want to use it, when you could wait just 1 second for it to come out of sleep? Ditto when shutting down vs putting to sleep.
Lots of people (like me) open their Mac up perhaps 5-6 times per day eg for a quick check of the weather, or some Googling. All those 30 seconds would really add up.
Since the OS & hardware are designed to go sleep/wake in perfect safety, why not use it? Mine hasn't been rebooted for 34 days now. I expect the next time I reboot will be when the 10.6.3 software update comes out.
