Imac awakens from sleep for no reason?!

So sometimes in the middle of the night my imac comes on from sleep. Usually it's very rare but it happened like 3-4 times last night. I know the next door nieghbor has an airport extreme, I pick it up on my wifi. Do you think someone's trying to hack in or is it coincidence? No I don't think I have a ghost either ; )

This may be something like a driver, application or external device which is not fully Leopard compatible, or even a component of MacOS if you upgraded to Leopard rather than did a clean install. To start the process of troubleshooting, first download and install the full 10.5.1 update from http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1051update.html , even if you have already updated to 10.5.1 using software update. The full updater has been reported to resolve a number of minor issues.
Next, assuming that doesn't resolve it, start up your mini, put it to sleep and then disconnect everything. If it continues to wake unpredictably, the issue is with the mini itself, and you may be best to backup all your data and do an erase and install to resolve any residual issues caused in the upgrade. If, on the other hand, the system remains sleeping, it points to an external device being the culprit, in which case plug each one in, one at a time until you can create the unpredictable waking again. Whichever component was last plugged in, is the primary suspect!

Intel Mac Mini wakes from sleep (for no reason) after installing leopard

My mac mini keeps waking after its been put to sleep (both by selecting sleep by hitting the power button or using the apple menu item.
This only happens now I've upgraded to leopard; with tiger, all was fine.
Any ideas what's going on? The iChat logging in noise blasting through my speakers at 1am last night gave me a bit of a fright!

When my IMac awakes from sleep mode, the password login screen freezes and no cursor appears.

Hello! When my IMac awakens from sleep mode, my log in screen is frozen (I can't type anything) and there is no cursor.
I can turn the computer off and on again and then I have an active log in screen, but if I walk away from the computer and it goes into sleep mode and i have the same problem trying to bring it back from sleep mode.
Thoughts?

Hey Kristogirl,
I understand that when waking from sleep mode, your iMac freezes. Try executing these two troubleshooting steps:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
OS X Mountain Lion: Reset your computer’s PRAM
http://support.apple.com/kb/PH11243
If neither of those help the issue, I would follow the steps in the next article, specifically the "If the issue occurs in various applications, or in Mac OS X" section:
Mac OS X: How to troubleshoot a software issue

IMac wireless mouse/keyboard unavailable after awakening from sleep - OS X 10.10.3

I am using an iMac21 inch late 2012. Has been working perfectly until I upgraded to OS X 10.10.3. Now when the iMac wakes from sleep neither the mouse or keyboard are connected. The only recourse is to force a hard restart with the power button.
i have tried the following to no avail:
SMC reset
PRAM/NVRAM reset
reboot (reconnects until computer sleeps & reawakens)
bluetooth off/on
repaired Bluetooth devices
Removed & reconfigured devices
I have set sleep (in Energy Preferences) to wait indefinitely & that has 'resolved' my issue. Albeit with an increase in energy use. Of course this isn't a fix.
I Would be grateful if anybody had some tips on how to resolve this situation.
thanks
paul

IMac wakes from sleep odd

I have an iMac G5 iSight, and for some reason it seems to be waking from sleep when I turn on my powered speekers connected to a different computer, or if I plug in something to the wall outlet, any idea why this is?

It is checked to wake for ethernet network admin access, but that is it. The iMac Is plugged into a wall outlet, and I have a Power Mac G5 plugged into a power strip that is plugged into the same wall outlet. I Have also noticed that if I am walking on my carpet and I touch the Power Mac, the iMac Will turn on.

IMac wakes from sleep on its own with Yosemite

After installing Yosemite, my iMac wakes from sleep all on its own multiple times throughout the day and night. The screen does not turn on when this occurs and it goes back to sleep on its own. I figured the my energy settings may have changed after the upgrade, but nothing is different. I have no schedule set and the "wake for network access" is unchecked.

To my knowledge, any Mac that is 1. connected to power and 2. not powered down will wake periodically for the reasons I explained, and perhaps for additional reasons known only to Apple. If disabling "wake for network access" does not change anything, all I can say is that it's working as Apple intends it to work. Before you ask, I strongly discourage you from finding clever system "hacks" or workarounds to prevent your Mac from working as designed.
It may or may not be a bug. Whether it is or not though, if it bothers you, consider providing feedback to Apple.
When questions such as yours arise, it helps to look at iOS. iPads and iPhones will all periodically connect themselves for the purposes of downloading emails, Messages, alerts etc. There is no way to disable that, other than to completely power down the device, which almost no one does. Apple has been inexorably changing OS X to effectively implement iOS design features such as this – for better or worse is not for us to say.
May I ask why this concerns you? Perhaps that would lend some insight regarding possible solutions.

Folder always opens when imac wakes from sleep

Don't think its a huge problem but when new imac wakes from sleep the same folder always pops up on screen(shaded in black). It always has to be closed before I can proceed with anything.Any suggestions would be appreciated. Also the folders name is always highlighted red. Thanks

Macmini 2011 on lion, goes to a blue screen om monitor when awakening from sleep mode, last 3 or 4 seconds, can anyone help? Thanks

Macmini 2011 on lion, goes to a blue screen on monitor when awakening from sleep mode, last 3 or 4 seconds, before desktop appears, can anyone help? Thanks

Depending on the system configuration, this may not
be unusual. The Mini that I use for my home theater,
which is connected to a receiver then to a TV, all via
HDMI usually takes a couple seconds to come up just
the way yours does. Same happens when I switch sources
on the receiver. Actually, it starts with the blue screen and
will sometimes flash before the desktop comes up.
It seems that when HDMI goes dormant, there is handshaking
that needs to be re-established, at least thats my SWAG on it.
On the other hand, the Mac Mini Server that I use as a work
station and is connected to a Thunderbolt Display, wakes to desktop
in a second, maybe two. On this combo, it just comes up to
the desk top.
It also probably depends on what processes were active when
the Mini was put to sleep. So it may take some time for it to get around
to reloading the desktop.

How can I wake my iMac up from sleep mode? Can I do it via iPad?

How can I wake my iMac up from sleep mode? Can I do it via iPad?
I've set the "Wake on Demand" in the system preference, but don't know the way to wake it up.

It wakes up automatically in response to requests for certain sharing services.
About Wake on Demand
Search for an OS X application called "WakeOnLAN." Search the iTunes App Store for iOS apps with "wake on LAN" in the description.

External hard drives ejecting after iMac wakes from sleep.

External hard drive keeps ejecting after iMac wakes from sleep. TM does not recognise, so have to unplug then re plug in Ext HD, only then TM will perform a back up. Not seamless backups. Help to resolve would be grand

Ive got the same problem with a Western Digital 500GB My Book Pro on my iMac Ive tried it on a few other machines and I think its happened on them, I say think because it was only when it had happened a couple of time that I started to take notice of circumstances etc and ive only had the drive a week, downloaded what may be a more uptodate "My Button manager" from the WD site still happened but Ive got this idea that it didnt happen on one machine which may not have had the MyButton thing on at that time, have you solved it yet I am using USB at the moment.

In Mountain Lion how to keep Dashboard from opening each time awakening from sleep?

Every time awakening from sleep and/or screen saver, the dashboard screen comes up as the opening display, how can I stop this?

Nope.
If you launch Mail, you get mail.
You can only stop if from loading if your DON'T launch Mail.
You can also decide how much to have it load, and how far back.
The other option is to turn off Wifi before you launch Mail.

Networking issues following upgrade to 10.5.8 when iMac wakes from sleep

Hello,
I recently upgraded to 10.5.8 and I'm now experiencing issues with network connectivity following the iMac waking from sleep. I have to stop Airport and then start it again to resolve the issue.
Can you provide any resolutions to this or advice?
Many Thanks,
Sam

Reinstall the Mac OS X 10.5.8 Combo Update because the Combo seems to help a lot of people when a Delta upgrade doesn't take right.

Spinning beach ball when awakening from sleep

I get the spinning wheel when awakening from sleep. Also my fans seem to be running a lot more than they used to. I've tried resetting SMC and PRAM. I recently installed a Crucial 256GB M4 SSD and enabled TRIM--not sure if that had anything to do with it. Running OS X 10.7.4 and have the latest updates. This is on an early 2011 MBP with 16GB RAM.
Anything I should do or check?
Thx

Seems to be a problem with the hard drive. Ok prior to 10.5.2. Affected drive: Fujitsu MHV2100AT PL 100gb

IMac waking from sleep several times at night

For some reason my iMac won't stay asleep. This is starting to bother me because my iMac is beside my bed and it wakes me up when I hear the hard drive spin back up.
