What is preventing my Mac from sleeping?

Ever since installing Lion, both of my Mac Pros don't sleep properly.
When the machine wakes, the Mail notification sound, sounds many, many times. EG: If I have receives 100 emails since sleep, it notifies me 100 times.
How can I tell what is preventing my Mac from sleeping, or is this multiple mail sound something else?

How to prevent hard disks from sleeping

Hello
I have recently installed a SSD for system drive in my machine, and now realise what a bottle neck the old, standard hard disk had been. Booting is now extremely fast, as is opening applications. This speed has alerted me to another problem. My hard disks keep falling asleep, which slows down operantion of the machine significantly. For instance, to log into this forum, I used 1Password. When selecting the log in menu item from 1Password, there was several seconds delay before one of the hard disk (I have four inside the machine, one external Drobo, and one external eSata drive) came alive. When it had, Safari could take me into the site. There constant delays like this when I use Safari, for example. These delays are very frustrating, so I want to keep all my disks awake constantly.
Thing tried so far:
The worst problem was the Drobo, because it has three disks inside that wake up one after the other, a very slow process, and the Drobo is slow in itself. So I installed a little script that does a touch command every five minutes, to prevent the Drobo from sleeping. It seems this has helped. But the other disks keep falling asleep all the time. I have set Cocktail to prevent all disks from sleeping - no effect. The Energy Computer Sleep setting is set to Never.
Any ideas will be much appreciated. This sleep issue keeps bugging my all day long.

In the Energy Saver system pref, are any of the boxes checked?
If it were me, I guess I'd try clicking the 'restore defaults' button in Energy Saver, restart the computer, and then go back into the Energy Saver and set the computer sleep to either 3 hours or never, and uncheck the 'put hard disks to sleep when possible' box. You might try 3 hours instead of never and see if that makes a difference.

Is there an AppleScript or Automator Script that will wake a Mac from Sleep?

Is there an AppleScript or Automator Script that will wake a Mac from Sleep?

Frank and All,
The following answer to your question above is complicated, but I hope it explains why my question was formed with so much frustration in it.
I have an OpenOffice(OO) Macro that was launched with Calendar at 6pm each business night. It ran properly in all Apples operating systems until I Hit Maverick(OSX10.9). From then on, the AppleScript would run from one to 3 days, then would disappear from the Calendar entry. The Calendar alert would still run, but the "OpenFile" section of the alert would disappear. I also was running elgato EyeTV HD during the day, so I would use energy saver to put my MacBook Pro to sleep at 12 Midnight and wake it again at 9am. I picked up a used Mac Mini to do the EyeTV stuff, provide AppleTV the files in H264 format through iTunes' media share, and found it had plenty of power to do the 6pm automated stuff simultaneously as well. Because I still wanted to run the OpenOffice Macro on my MacBook Pro at 6pm, and wanted to use it for a host of other things when I was on the road, I wanted it to sleep most of the time and only wake up automatically to run the 6pm OO Macro. When I called Apple about the issue I was having with Maverick and Calendar loosing the OpenFile command as part of the Alert Message, they told me the no longer supported answering AppleScript Questions but they now would support Automator questions. I pointed out that the OpenFile would also fail after one to three days if I used a Calendar Alert to launch an Automator App. At first, I did not like Automator, but now I see why Apple is pushing us to use it. Automator adds a TIME STAMP ID to the Apps developed in Automator so the first time you launch the App after a change to it, you must reply to a dialog message saying that this is the first time you are running this version of the App. If a Scammer has replaced your app with one that can reek havoc on your computer, the replacement app will not run unless you are there to agree that you know where the modified app came from and click the OK button to continue (BRILLIANT, Enhanced Security idea on Apples part). I also noticed that after Mountain Lion, the Applescript delay timing was all screwed up as well. Well I tried to use LaunchD Task Scheduler to circumvent the Calendar Problem and that worked until I upgraded to Yosemite Last week. Then LaunchD no longer worked and I am only into a few days of using The Calendar Launched Automator App to see if it will continue to run.
But I think I solved the dilemma I was having with opening an Automator App in a Sleeping Mac. I Googled up the following question, "AppleScript to wake up computer". I went thru several complex responses until I found this on that is INCREDIBLE EASEY! What came back was a brettterpstra.com response from Feb 20th,2014. What it said, in a Quick Tip: caffeinated your Terminal Article, if you wanted to wake a Mac from sleep, use the Terminal command named "Caffeine -u -t 1". I placed it in an Automator Most Used Action called "Run Shell Script -- Caffeine -u -t 1" and it worked! Now, I can put my Mac to Sleep but at 6pm, the Automator App will launch, run the "Caffeine -u- -t 1" command and proceed to work as if I had awakened the Mac From Sleep mode by pressing a keyboard key and had run the Automator Script with a double click.
Sorry for the long, drawn-out reply, but maybe this will help others.

Flashing screen when awakening my mac from sleep

Help: What can I do to fix my screen issue-- It flashes for the first 20 seconds each time when I awaken my mac from sleep mode: Thanks!
(mac pro 2007 intel based)

Thanks, Linc. I was worried that since this was a refurbished computer, it was dying again. Makes sense, although alittle annoying that nothing really warns you this is happening. I almost cycled power the first couple times it happened, thinking it was stuck while waking.

Is it possible for skype to wake Mac from sleep mode?

Does anyone know if it is possible for skype to wake Mac from sleep mode?

Sadly there is nothing in Skypes Code fot it. In fact, Skype for Mac, is one of the most Vanilla versions out. Windows Version has 5x-10x the user functionality. Since Microflops buy into Skype, Mac versions will continue to be second rate on purpose, but be thankful, if Microflop was there from teh beginning, they woudl have banned a Mac version, just like they do in their higher tier games.

Logic Pro prevents MacBook Pro from sleeping

I've been having trouble of late with my MacBook Pro -- it has been refusing to go into sleep mode on its own. I sat down and did a bunch of careful experiments turning various things off and on, and I've narrowed it down to Logic Pro 8! If this application is running, my MBPro will not sleep automatically. If I exit the application, it sleeps like a baby. In any case, I can force the machine to sleep manually no problem.
I am not sure whether this problem first occurred with 10.5.4 or 10.5.5.

If in fact it is Logic preventing the system from sleeping (and I think it probably is) this is new since version 8 and is probably the direct result of all the complaints version 7 received.
I'm afraid I don't find these responses to be very compelling, sorry.
First, it has always been trivially easy to turn off the sleep function on an Apple machine. Everyone who owns an Apple knows how to do this simple thing.
Second, sleep does not cause failure of any kind for properly working audio hardware and other attached devices. I have three audio interfaces connected to my machine, plus an eSATA drive, external video, and ethernet cable, and the machine sleeps and wakes up just fine. No problem. This has nothing to do with audio or real-time anything, it's just a question of writing a device driver correctly. It would be the same for a printer or a camera or anything else attached to the computer. I have one device that does not sleep and wake properly: a western digital hard drive when connected by eSATA via the ExpressCard/34 slot. Again, there's no relation to audio or recording or Logic.
I wonder if there's anyone from Apple reading this newsgroup who can comment on the actual intention. If it is indeed to disable sleep, it would be nice to know. If on the other hand, it's unintentional, maybe it means that some other setting is wrong or there's something to be done about it.
Thanks,

What can prevent NI-DAQ from installing on a computer?

I was able to remedy problem by using windows explorer to view ni-daq cd and run the nidaq.msi in the nidaq dir. Going this route caused a user window to appear that allows you to remove all / repair etc. I selected the remove all option which then removed whatever had been installed on previous installation. I then went the usual route of control panel\settings\remove s/w to remove the MAX. I then went back and ran setup.exe in the nidaq cd root dir and everything installed properly. The key was the first step mentioned above. The control panel\settings\remove s/w display did not show ni-daq evidently due to prior improper installation which prevented uninstalling this way. The autorun feature of the ni-daq cd did not deal with the improper installation because it would simply say it successfully installed when it did not install any thing. The original installation that improperly installed the ni-daq was when I installed the labview full development system. Everything else installed correctly at that time except for ni-daq. Who Knows?

Can I wake my Mac from sleep with network activity?

Just got a MBP and now am enjoying mounting it on my iMac and vice versa via my home network (using URL address with AFP://xxx.xxx.xxx.local). Question: Is there a way to wake either one from sleep when I access it from the other?
TIA,
Picman

Elamc,
OK, I now know. Some Macs will support both Ethernet and wireless and some won't. The setting in my MBP says "Wake for network access", while my iMac says "Wake for network Ethernet access". The MBP supports both, but the iMac just with a cable connection. I did find a good tech note that describes the how's and what's. Just Google "Mac wake on network access" and look at "Mac OS X v10.6: About Wake on Demand".
Thanks for your info ... it helped.

Any way to prevent macbook air from sleeping when lid closed?

I believe there is no way to keep your macbook/air running when you shut the lid.
I am running a background job where I am downloading a huge amount of data from the internet, which is coming through slowly (other applications could be where I am running a web server....). I want the machine to be running, but not keep the lid open - since I might want to move the laptop, not leave the screen/keyboard exposed.
Where can I request Apple to add support for this behavior? Or did they anticipate this request in Mountain Lion already?
Any suggestions? Others who would like the same feature?

NoSleep makes closing of your MacBook lid possible without going into sleep mode. Now you shouldn't plug your mouse and monitor to stay computer awake - just check a tick in the System Preferences and continue downloading of huge files and watching favorite movies over the network with lid closed.

Reconnection issues with Mac (from sleep)

Hi, I have only had BT infinity for a few days now, but this is driving me mad already.
When I turn my computer on, I don't have any problems, finds the network straight away, connects and I'm ready to go. However, if I put the computer to sleep/standby (close the lid), when I want to use it again, although it shows I'm conncted to the network, nothing will load, I get the 'your not connected to the internet' message in my browser. The same with emails etc, can't find the server. no matter how long I leave it, it won't sort itself out. I have to manually turn wifi off and back on again to rectify the problem.
As you can imagine, this is becomming a bit of a pain, so if anyone has any ideas I would be most grateful.
Cheers
djt1

Ermm, now if you go to the Airport Icon and click on Network preferences, and then the wifi networks have you made sure BT Fon or BT Openzone are not set to connect? If they are in there then delete them.
And the only other thing I can think of would be to Remove the Wireless Network in question, restart the mac, and then re-add the network, restart again, and then see if you still have the same problem from putting the Mac to sleep.

Is ARD supposed to wake up macs from sleep?

Hi all! I have the latest ARD and the latest Lion running, with several macs on a lan. My question is, is ARD able to wake them up from sleep? Currently, it does not, and looks like this in the interface:
Well, thx in advance for any advice.
Message was edited by: coocooforcocoapuffs: forgot to mention that when awake, connections are made and all is peachy.

If you can't get it working, worse comes to worse you can always keep display sleep on and put hard drive(s) to sleep and disable the normal sleep.
My Air has wake from WiFi options, but I don't think other systems do.
I think if the system drops from the shared volumes on your finder (if it's sharing files), it won't be accessible via ARD or Screen Sharing.
Well, I can't say I understand that last bit, but the workaround works, but these boxes all have the Nvidia defect and I want them to stay as cool as possible when not in use, not sure the workaround accomplishes that but I can test temps. Maybe these MBP 3,1s don't support wake up over wifi? the strange labeling on the preference pane implies that ? dunno. but thx for your help!

What will keep a system from sleeping, other than user activity?

If I'm, say, running a long video transcode, will that prevent automatic sleep, or might sleep kick in anyway in the middle of things and possibly screw them up? I think this may have happened, so I'm considering disabling automatic sleep if it presents this sort of liability. TIA... Mark

Programs actively writing to disk should keep a system from sleeping. That said, I've always turned off sleep on my systems when doing important processing, just to be sure. Some software can pause for significant amounts of time and while they should still be keeping the processor working and so prevent sleep, it's not foolproof, so I err on the side of caution and set my systems not to sleep other than the monitor when they're going to be processing for a while.
Regards.
