When I put my iMac to sleep it puts my Mac Mini to sleep as well.

The Mac Mini goes to sleep when the iMac is put to sleep and the Mini will not wake up unless the iMac is awake. I have made sure that all sharing is off but it did not fix it. Cannot figure it out!

When I wake my iMac from sleep, the wireless does not connect. I have to shut shutdown and then restart and then it connects. I am running Lion 10.7.3 Any thoughts?

Been waiting along time for this problem to be fixed. Unfortunately the update hasn't help at all and even made the situation worse. Now my airplay connection from iMac to stereo abruptly stops after about 10-15 min. so I have to go over and quit wifi, start it up and find my airport network. Not sure why it always has a problem with the apple airport network. My neighbor's pc network is always there.

Sometimes after putting my iMac to sleep, I can't get it to wake up and have to turn it off at the mains. Any ideas why?

That message means that you have to restore the iPad now. Something went wrong. You need to restore the iOS software and then restore from the backup.
Read this carefully and follow the instructions. Make sure that you restore from your backup at the end of the process. That is covered at the bottom of the support article.

The new version of Itunes is NOT interfacing correctly with my Airport Express device and I get an error message when I put my macbook in sleep mode. Anyone else dealing with this?

When I put my mac in sleep mode I get an error message and I have to click on it and then select whethere to play on computer or airport express. This was not true with the old Itunes but with this new version it is true. Any help?

well nobody bothered to give me a hint on what to do, maybe because the problems with the new version of iTunes are really a lot, there is an enormous amount of people out there that have all sort of different problems including mine so I have decided to return to the previous version which works fine and wait untill the apple people come up with a decent product ....

This is so basic: How do you turn off Apple TV, or do you just exit by changing the Input back to regular TV? When I put Apple TV to sleep, I had to log in again, a very tedious process with that awful "announcer" for the hearing impaired (how to remove?)

Welcome to the Apple Community.
The Apple TV will put itself to sleep. I'm not sure what you needed to log into again, but you shouldn't have to. Do you have a little more detail about what happens.

James did you find a solution? Last night my daughter put her Macbook Pro to sleep and now it won't turn on or charge? I think it is not charging because the light does not come on. We charged mine and the light came on and worked so it is clearly her computer. Help!!!

Screen freezes up when I wake the iMac from sleep

Hi, all. This is my first post to Apple Discussions, so please pardon me if this is a dumb question. I have had a problem twice in the last 24 hours. I have an iMac G5 that I keep on most of the time. I do put it on sleep mode when I'm not using it. This morning, and then again this evening, I had the iMac on sleep mode. When I woke the computer, the screen came up, as usual, but when I went to click on the Safari icon, the screen became fuzzy and locked up. Powering the unit down was the only way to restart the computer. After that, things worked fine. However, this is a new occurrence. Is it something serious? Is it easily fixable? Is this common with iMacs? Just wondering. In the meantime, I'll probably just use the "shut down" command when the computer is not in use. Thanks for any advice that you can offer.
iMac G5 Mac OS X (10.3.9)

How can I put my iMac to sleep after it has finished downloading or uploading something?

For example: I have some photos and videos that I want to send to a friend. I'm uploading them to a site to do this, and they're quite big files (250 MB).
I'd like to do this at night, but I don't want to let the computer run all the night through, when this maybe only needs a few hours.
I can only guess how long it will take (judging by the time it tells me that it will take, if available), and then I can set the computer to go to sleep after X hours or minutes.
Can I not just simply set it in a way that it goes to sleep automatically after the process is finished? Like, if there's a connection to the internet, that is being used (downloads, uploads), then it shouldn't go to sleep, else it will interrupt the upload, and I can start again.
Also, I have an iMovie update now, which is over a GB of download.
I may be mistaken, but I have the feeling that for some Apple programs, it actually keeps the computer awake until the process is done. But it isn't the case with all programs, only with some.
It's really annoying. Does anyone know a solution? I know that there's this box that you can tick, that says something like to keep the computer from going to sleep if there's a network connection, but in earlier OS this was actually working! Now it's 100% useless.

You can just set your Mac to sleep using the Energy Saver in System Pref. Set it to sleep after say, 2 mins of inactivity then check the Put Hard Disk to Sleep setting too. It won't sleep while you are down/uploading.

Putting my iMac to sleep crashed my jump drive.

So I was working on a project in after effects off of a jump drive. I put the computer to sleep because I had to go help a friend move. I left it in sleep mode over night and when I came back to it, it refused to read my jump drive. The thing was still in too. It didn't even give me the option to eject it. So I pulled it out and put it back it. I would read it for a second and then it gave the disk not ejected properly reading. Anything I can do or is it just crashed?

Repair it with Disk Utility.

Does your Wifi drop when your iPad mini went into sleep mode after upgrading to iOS 7?

Dear iPad mini users, to those who have upgraded to iOS 7 like I did, do you experienced WiFi drop when your iPad is in sleeping mode? I noticed this problem only few days after upgrading my iOS. Initially I don't think there is such issue. After your iPad mini recover fom sleep mode, then it will automatically connect to WiFi again. My point is it no longer connected to WiFi in sleeping mode and so could not keep me up-to-date with my mail if I am on WiFi.
Do share your view and if there is a solution, do share with me please. I have tried almost all solutions available online but no no avail. At the moment, I am activating my 3G network so that when mail came in, my iPad will notify me even during its sleeping mode but this is getting expensive considering I am using the 3G 24 hours every day now.

I found an solution. Go to Settings/Mail, Contact, Calendar/Fetch new data and than enable Push and choose to fetch hourly or every 30 minutes. In this case your iPad will stay connected to wifi even when smart cover is closed. If you select Manualy than wifi connection will be terminated when in sleep mode.

Lost Cursor Control and locks up after putting the iMAC to sleep

Has anyone an idea why the iMAC locks up and will not accept mouse of tracker controls after putting to sleep for a awhile?

Yes, just put your computer to sleep whenever you judge it right.
The three nightly maintenance tasks are not important enough to change your habits,
they do not affect OS X performance: only disk space.
And yes, since 10.4.2 they are automatically delayed if your computer was sleeping, but you still have to run them manually
— all three together once a month is fine —
if you sometimes shut down or reboot your computer.
Use this Terminal command
sudo periodic daily weekly monthly
or one of the "cache-cleaners" utilities like Cocktail etc.

Putting my iMac to sleep shuts it down

Whenever my iMac goes to sleep the whole computer shuts down - this happens if I go to sleep using the Sleep function manually or when it goes to a scheduled sleep.
Is this a power supply issue (repair extension program) or something else?

You should reset your SMU, this controls your sleep and shutdown functions.
Please post back with results,
Miriam
