My Mac has insomnia
For a wile now my Mac has been unable to sleep through the night. When I get up in the morning, it is already awake.
What is causing this and how can I fix it? I've reinstalled Tiger and that didn't help.
This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
Here is Apple doc.#303698 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
Also, here is Apple doc.#305262 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Good Luck! DALE

Mac has insomnia. Keeps waking up from sleep.
I have had problems with my various Macs awakening randomly. I had a core2 duo iMac and now I have an i7 iMac, and it seems that I have a pattern. I sleep the computer and it comes on suddenly. Sometimes it goes off, but other times it stays on. I have set up the computer to go to sleep after 25 minutes: both the display and the computer. I have checked "put hard disks to sleep when possible".
I have tons of RAM and am running Mavericks. I run Parallels desktop too. I have a first generation time capsule and a 2Wire DSL modem. The 2Wire has wireless capabilities, but I just have it feeding the time capsule with a single ethernet cable. My wife's macbook Air wirelessly and automatically backs up to the time capsule as well. I have a brother wireless laser printer and an HP wireless inkjet printer. I plug in a Denon audio receiver via ethernet to the time capsule. There is a ROKU box that connects wirelessly to my network. I don't have file sharing turned on, but I do have dvd/cd sharing checked. I don't have any other remote management protocols set up.
After I upgraded my computer to a new (used) iMac, I was dismayed to find the problems persisted. I have been scratching my head and wondering whether it could be the time capsule or the 2Wire that is the problem? I have not tried disabling time machine for either computer to see if that was the issue. I have not unplugged the time capsule and just used the 2Wire modem to trouble shoot.
I know there are certain things that can be queried via Terminal, but I don't know enough to choose what to type in. I sometimes want to tear my hair out when the computer suddenly coms on in the middle of the night, or when I can tell it has been on for hours in the morning, by touching the iMac and feeling it to be very warm.
JimTest after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer will not sleep if Internet Sharing is enabled.
Step 2
From the menu bar, select
▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 4
Reset the SMC.
Step 5
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 6
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 7
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again. -
My mac has OSX version 10.8.2 and I'm try to install an aiport express base station which requires 10.5.7 or later. Yet when I try to install the software it says the base station is not compatible with my mac version - how do I resolve?
You already have the software installed that you need if you have 10.8.2.
If AirPort Utility cannot find the Express, that is another matter. More software is not needed. More troublehooting is needed.
Power up the Express for a full minute
Hold in the reset button on the Express for 7-8 seconds and release
Allow a full minute for the Express to restart
Click the AirPort icon at the top of the Mac's screen
Look for a heading of New AirPort Base Station
Just below that, click on AirPort Express

My laptop was stolen but "Find My Mac" has located it. Now how do I get it back?
Hi All,
Early this morning, a friend of mine called me to tell me her laptop was stolen. She asked me to help her track it using iCloud find my mac. The theives also stole her wallet and other things from her car so this isn't something that was just misplaced and an innocent person came across it. My question is, now that I know where it is (within a couple hundred feet vicinity) what is the best approach I can use to get this back for my friend? She's got years of family pictures and does not have the laptop backed up so this is very important to her. Any ideas?
It shows the laptop around 4200 S Wade Way (about 3260 w), West Valley City, Ut
Please, any advise would help!
Thanks,
CalebWell, I did contact the police with all this information. They actually went to one of the houses with me (the one on the corner) and it was an old man who was very polite who lived at home alone and didn't seem like the type. Instead of knocking on the other doors with me, the police said, "Your locating program is probably just wrong and it's not here." he wouldn't knock on any other doors so I plan on going tomorrow morning and knocking but the chances of anyone confessing are slim so I don't know what approach to go at with them. I don't know why find my mac doesn't let you leave a message like find my iPhone because I would leave a message saying "this mac has been misplaced. If you return it, the owner will reward you with $500 without pressing charges or asking how you came across the laptop. Please call -------, but, no. All I can do is knock. lol

My Mac has stopped receiving mail. I have a mac.com address. Mail is still coming through to my iphone and my wife's ipad but nothing is coming through to my imac.I have mail from half an hour ago on the phone but nothing newer than 18 Feb on the mac. Everythng was working fine until recently and I have not touched any settings! Can anyone help?
So I tried something else recently and it seems to have fixed the issue. My mail is now getting new mail again and refreshing after waking from sleep without having to restart mail. Give it a try and hopefully it will help you too.
First, make sure your Mailbox List is visible (Shift + Control + M). Then select all of your inboxes, mailboxes, and folders (not just the root folder for nested folders, make sure to select them all). Then under the "Mailbox" menu, select "Rebuild."
It may take a while to rebuild them all if you have a lot, but like I said it seems to have done the trick for me. I hope that proves to be more of a long-term solution. -
My iTunes 11.0 (mac) has a black background colour and I can not see all of the information for each song. How do I change the background colour in iTunes 11.0 (mac) so I can see check boxes etc. My download window shows no information, it is entirely black.

Someone else in the forum told me how to do this. If you have Onyx on your system then select Parameters, iTunes and turn off high contrast mode. If you don't have Onyx, I'd suggest getting it. It is freeware and used to help maintain your system. Good luck

My I Mac has developed a pink cloud in part of the grey top bar and also if I leave for awhile with Safari or anything else left on when I return it has closed these down and I have to re open them, has anybody got any ideas how to cure these problems if possible.
For FaceTime try the troubleshooting advice given here:
http://support.apple.com/kb/ts3367
Also try resetting your iPad:
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10-15 seconds).
No data will be lost. -
How can I find out if my mac has a trojan with out third party software?
I'm trying to find out if my mac has a Trojan on it. I got a pop from a tech support site warning my computer security could be compromised. I did not click any of the links in the site but did call the number. I got very suspisious when they told me the were certified microsoft tech support and told me there was "something band inside my computer". I'm pretty sure they were bogus and just going to try to sell me junk. But after much research I'm very concerned about the ramifications if I do had some kind of Trojan. I have done a bunch of research, most of the content I have found is from 2012/13. Don't want to purchase apps-sounds like there not that great, even ClamXav which can get stuck in a loop as stated on their site. I don't know much about DNS but sounds like it is may the fix. Does anyone know a good source for current info on Trojans and how to detect them. I'm running OSX 10.7.5 and an older iMac.
See Tech support scam pop-ups.
ClamXav which can get stuck in a loop as stated on their site.
That's mostly been fixed for a long time now and can easily be avoided by following the instructions. -
Is there any other way to find out if your Mac has a virus?
I think antivirus software is the only thing that can tell if you've got trojans and harmful files on your computer, and lists them down. But I want to find out if my Mac has viruses without downloading AV software.
There's no one single method that can be used, as different malware can install in different places. You have to know what you're looking for. The folks who make AV software know what they're looking for, so that's the best option.
However, why do you have this concern? Do you have a reason to believe your Mac is infected? If so, what is it? If not, you can probably relax (though that's far from a guarantee).

My Mac has suddenly stopped playing my DVDs including a DVD it played fine only 3 days ago. I insert the DVD and wait for the player to start automatically but after 10 minutes, nothing is happening and it sounds like the disk has stopped spinning. I've now tried with four different DVDs (all store bought and so perfectly normal disks). The Mac doesn't eject the disk or anything it just doesn't seem to respond to it being there at all.
My main confusion is why this suddenly happened today when it was perfectly fine last week.
Does anyone have any idea what could be wrong and how I could fix it? Thank you.

My Mac has been stolen, but I have my iCloud account setup. The "find my mac" app has found the apartment block it's in, but I need an IP address for the police to go and claim it. Is there a way to see the IP address of my Mac through iCloud? I've tried to get the IP address through Gmail and Dropbox but no success. Is there any software that updates automatically that I could find the IP address through?
Shouldn't the IP address be on the box you bought the machine in? If you have the box, take it to the police as evidence that it's your machine. If I were you, I would set the firmware password when you get it back, but make sure you have the password written down in a safe place. If you forget it, there's only two ways to reset it. Either pay $400+ for the tool that can do it, or pay almost nothing for Apple to do it, I think it depends on where you live. The firmware password is this encrypted password and it can't be hacked either. The password prevents anyone from booting the machine into recovery mode, thus preventing them from restoring the computer to factory settings or performing any other functions. It's not stored in the hard drive so replacing that will be of no use either.
I hope you get your Mac back and I hope this was helpful!
