My Mac sleeps every night. Just checked when the scripts last ran, the daily script ran this morning when I switched my Mac on.
 
My computers just sleep. I don't see any point in powering off and on ever day.
 
I put my iMac to sleep, like the manual says. But if I'm away for the weekend I turn it off, like the manual says.

Yeah, I know...I read too many manuals and I don't get out much.
 
Never off, just in sleep mode when not in use.
My C2D iMac used to be "on" 24/7 as it used to double as a media server on my home network. Thankfully that changed with the release of snow leopard and wake on demand.

I usually only rebooted once a month with the C2D, I will monitor the i7 and see if I need to change my practices.
 
I prefer to leave my hardware OFF when not in use. Of course, i come from the days of DOS, so I never really bought into the hype of "turning off your computer is bad for it". I still think it's a sales tactic to prematurely burn out hardware so they can sell you more :rolleyes:

The exception to this is my wife's 24" iMac, since the majority of our son's movies are stored on her HDD, so it's set to sleep, wake on lan.

And as far as scripts are concerned, there's this nice little freeware program called Onyx, which allows you to run basic maintenance [including daily/weekly/monthly scripts] at will. Sure, it's not as conveient as just letting the system do it for you. . . but just because you own something as convenient and relatively automated/low maintenance as a mac, it's just not acceptable to use it as an excuse to be lazy :D

[or more to the point, I've spent so many years tweaking and cleaning windows systems i have an obsessive compulsion to keep things tuned. Everyone has their own little habits ;) ]
 
With the computer off or in sleep, OSX won't do its maintenance schedule between 3am and 5:30am every day.

@300D - quit insisting you know what you're talking about when you don't: http://lausd.apple.com/groups/lausd/wiki/5ea1b/Mac_OS_X_Tips__Maintenance_Scripts.html

In Mac OS X Leopard these scripts are now scheduled using a technology (launchd) that is no longer dependent on the computer being on that those specified times. If a computer is not running at the prescribed times the scripts will automatically run the next time the computer is started or wakes from sleep.

I never turn off any of my computers. I set-up automatic sleep schedule between 1am and 8am.
 
My PC probably doesn't count, but i turn it ON and OFF several times every day for the last ~6years and no problems so far. Intend to do it with my new iMac, why not?

The maintenance scripts are not run when the Mac is in sleep mode or turned off. I just checked and my scripts have not been run since the 11/25 (now 11/30) and the machine has been on everyday. I ran the scripts manually. For newbies or anyone who does not know how here is a great link that you may want to print and keep by your Mac:

Here is a widget you can download that will run the scripts for you when you want:

BTW, I turn my i7 off over night but usually put my MBP to sleep. No rhyme nor reason, just habit on the MBP.

Right, if the Mac is asleep/off during the regularly scheduled times, the scripts execution will get time-shifted. So the scripts may not end up running on a daily/etc basis, depending on the computer being awake or not.

On my system, the scripts get executed eventually, just not always on their periodic schedule. It's not a big deal. If someone feels they MUST have these scripts run on their official schedule, just run 'sudo periodic daily weekly monthly' from the Terminal. But in my opinion, this is NOT a good reason to keep you machine on 24x7.

I agree. If the computer isn't going to be used for a 6-8hr period, might as well shut it off and conserve the energy. Think of the rainforest and polar bears guys!! ;)

Check your MBP and you will probably find that the daily script is run after you awake from sleep.

Due to the way launchd works, the scripts will not run if the iMac is off, only when it reawakens from a sleep.

Hi Tom,

Apples tend to be more stable than PCs, so the need for a restart isn't that great. However, turning it on and off on a daily basis does not hurt either. (some may argue wear-n-tear, but I'm not convinced that this matters, especially given the fact that most people upgrade at least every 5 years). One advantage to using sleep is the computer is ready to go when you are versus having to wait for it to boot.

In the end, it comes down to personal preference.

Hope this helps,
Bryan
 
Yes, I shut the computer off when I’m not using it and when I’m gone for extended time. I don't think leaving on your computer 24/7 for weeks on end is a good idea. Just like anything else, things burn out faster when it is in constant use w/ no rest! And the waste of energy. It might not be a lot of energy in sleep mode but adds up just like all of those stuff that are plugged into your outlets but not in use are still draining some wasted energy.

I think some would argue that this is false and that the constant turning on and shutting down does more harm. Not sure if there is any scientific evidence/study to support this or not. Just one of those things you hear thrown out there. But I completely agree regarding the wasted energy. Everything does add up. Might as well do my part to minimize my footprint.

Several years ago I took all of the MCSE courses for work. When I took the A+ certification it was pointed out that the hardest thing for computer hardware is to turn it on and off on a daily basis. I had also read this in various technical articles. Where I work we are not allowed to turn off the PC's, only the monitors after we log off at the end of the day. We are talking around 70,000 PCs and over 2,000 servers left on 24/7. I can't imagine the electric bill. I am personally responsible for approximately 75 PC's. These PC's are incrementally replaced every 3 - 5 years. Leaving them on does not affect them. Considering the number of PC's there are very few hardware malfunctions. When we had the small footprint PC's there were problems from heat. Needless to say, they were not part of the next replacement buy. My wife told me that an item in the news the other day said that leaving PC's turned on really drives up the utility bill. I don't know how accurate that statement is. I can't imagine that sleep mode (or standby in the XP world) would cost that much.
 
Trek2100,

Another reason may be overnight maintenance (antivirus, backups) run on larger networks overnight. I was reminded about it by our IT, when I started shutting down my computer at the end of the day...

Why do you keep repeating this, as if you're telling us something we didn't know? I don't think anyone has stated anywhere in this thread that the periodic scripts will run while Mac is off/asleep.
