Since I installed Mountain Lion, my iMac has shut down after 15-20 minutes. I have adjusted screen saver, shut down time, and sleep after. Nothing seems to help, any ideas?

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Screen saver shutting down mac

I am new to macs. I have set screen saver on my mba to start after 5 minutes of inactivity with the cosmos photos. What happens is that the pics come up after 2 minutes and then the computer turns off. I have to close the lid and input my password to start up again. Is this normal or have I done something wrong?

Im assuming you downloaded some 3RD PARTY screen saver not already on your Mac?
Remove it and use a Mac resident screen saver if so.
Mountain Lion is oft to reject many screen savers by 3rd party that USED to work on snow leopard and Lion .

My ipad showed a blue screen and shut down.

My ipad showed a blue screen and shut down. I cannot restart it. A soft restart did not work. I tried connecting to iTunes on the PC but it did not detect the device

Did you try resetting the iPad?
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears- let go of the buttons.
If that doesn't do anything, try this for the issue with iTunes not seeing the iPad.

If that doesn't help, restore your iPad using iTunes or iCloud > iOS: Back up and restore your iOS device with iCloud or iTunes

Shut off screen without shutting down accelerometer in Touch

Due to Apple firmware limitations in the 2G iPod Touch, it is not possible to shut down the Touch screen and keep the accelerometer running, so running the Sleep Cycle application on the iPod Touch causes the screen to stay on all night and become very warm
Apple please please could you change the Touch firmware to support shutting off the screen without shutting down the accelerometer so that Sleep Cycle can be run on the Touch like it now runs on the 3G and 3GS iPhone.
This would open this excellent little application to the whole Touch market segment, making the developers very happy and allowing me to get up in the morning.

This is a user to user forum and Apple will not hear you. You can address Apple directly here: http://www.apple.com/feedback/ipodtouch.html

My screen just shut down and it wont turn on

My screen just shut down & wont turn back on What can i do?

What happens if you try a hard reset? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear. You may need to attempt this more than once.
Otherwise, connect it to an external power source and leave it to charge for a little while and then try a reset again if necessary.

Screen unpredictably shutting down during phone calls.

Anyone understand the logic behind when the screen shuts off during a phone call.
I'm using the keypad a fair bit and sometimes the screen will shut down during a call, hiding the keypad. I can shake it and it will come on again but then sometimes it goes away.
Sometimes it just stays up the entire call.
Sometimes it shuts off during the call.
If it shuts off during a call I can shake it to get the screen to come on.
Sometimes it just stays up for the rest of the call.
Sometimes its shuts off again.
If it shutss off during a call I can shake it to get the screen to come on.
Repeat...
Quite frustrating. How do I get it to stay up?
Can I?

My iPhone does the same thing. When I make or receive a call the screen seems to do the opposite of what it should do. When I put the phone to my ear the screen activates, when I pull it away the screen locks. This causes me to press the touch screen when talking on the phone, buttons like mute and keypad.. highly frustrating. Also when I try to hang up, the screen locks preventing me to end the call.. have left numerous unintented voicemails due to this.
I have tried adjusting the auto-lock setting but this does not help and is up-to-date. Any ideas?

You should be able to turn off your MBP by pressing the power button down continously for about 5-10 sec. When you reboot it you are going to want to enter into a terminal screen. Hopefully the following YouTube video helps: http://www.youtube.com/watch?v=qKOX72xNmbo

Dear all, Since a week ago I observe that when I press the button for my macbook air to start a nap, first the screen turns to black but I can see the arrow (pointer). And only after few seconds the arrow and the screen really shut down.

Dear all, Since a week ago I observe that when I press the button for my macbook air to start a nap, first the screen turns to black (although I can see it is stil on) and I can see the arrow (pointer). Only after 15 seconds the arrow and the screen really shut down. It did not occur before, as a matter of fact it was instantaneous. What could be the problem?

Note the time in your Mac's menu bar or some other accurate timepiece. Then, press the button to put the MBA to sleep. Wait until the cursor disappears and for all indications that the Mac appears to be asleep.
Then, wake the Mac the way you normally wake it.
Then, find the Console app - it is in your Utilities folder and looks like this
You can find it by selecting Utilities from the Finder's Go menu.
Open Console.
If the log list column on the left is not already displayed, show the log list by selecting Show Log List from Console's View menu.
Locate system.log in the list and select it. Many date and time-stamped entries will appear, hundreds of them, and you must find the entries relevant to your Mac's sleep problem. To do that type the words sleep cause in the Filter field at the upper left of the Console window:
That will cause all log entries to be hidden, except for the entries containing those words. The last entry in the list will correspond to the last time you woke the Mac. It will have a time stamp in the form hh:mm:ss later than the time you noted in the Mac's menu bar prior to putting it to sleep.
Make note of that exact time in hours, minutes, and seconds.
Next: Clear the filter field by clicking the x in the above screenshot. It should then look like this:
All previously displayed log entries will reappear.
Next: Find the log entry that corresponds exactly to the time you noted in hours, minutes, and seconds containing the words "previous sleep cause". You may have to scroll up or down a considerable distance. When you find that line, select it and drag your cursor up and prior to the entry corresponding to the approximate time you noted before putting the Mac to sleep. This will result in a selection of perhaps 50 to 100 lines or so.
One or more of them, along with their time stamps, may reveal the reason for the fifteen second delay.
Copy and paste those log entries in a reply.
Most of the entries will be cryptic but will contain information you might consider personal such as your Mac's name. If you do not want that information to appear, delete or obscure it when posting your reply. Leave enough information so that the entries can be deciphered.

TS1473 My hp laptop boots but the monitori screen stays shut down and inoperable. There was no overheating, physical damage , or system issues. Video graphics card had errors

My hp laptop worked fine, I shut down, attempted normal boot process several days later and power boots but the monitori screen stays shut down and inoperable. There was no overheating, physical damage , or system issues. Video graphics card had errors

You would be better off posting this in an HP forum, this forum is for Apple products.

Permanent blue screen on shut down

Hi: Since a few days I cannot properly shut down. The blue screen with the revolving circle stays for ever and I have to do a hard shut down (pressing power button 5 seconds). This even happens after a save boot with all extensions disabled and all peripherals disconnected.
I did:
disc check,
permissions repair,
SMC reset,
Apple's hardware check,
PRAM reset,
to no avail.
Any ideas? Thanks.

This is for a Mac that won't shut down. Launch +Activity Monitor+ and see if there are any active applications besides Activity Monitor ( items with icons next to the name), select them, and click Quit Process.
If an app won't quit by clicking Quit, click Force Quit. Then try shutting down again.
If that doesn't work start killing off system-managed programs ( items without icons ) . Be sure to quit only the programs your user account is running; don't quit anything identified as "root" or "nobody" in the User column- and whatever you do, don't quit any of the following : loginwindow, Window Server, ATSServer, or SystemUIServer, which make up the foundation of Mac OS.
Quit one process at a time, and then shut down after each kill until you find success!
I wish you luck!
p.s.If you install two of a single user licensed third-party application on different computers which are networked, this symptom may occur. If that is the case, a solution is to perform "Erase and Install" for both computers.

Shortening Energy Saver Shut Down Time?

We have a Keynote project where the presentation is on a Mac-Mini and it automatically starts and stops at set times using Energy Saver and Automator as part of a big display in a local Museum. The presentation starts up great at its designated time but when Energy Saver goes to shut down, it takes literally 10 minutes. I would like to shorten this to something like, one minute. Any suggestions?
Here's the setup:
I have the Mac-mini set to automatically start up every day at 9:00 am and shut down at 5:30 pm
The Keynote presentation is set up in Login Items to open at startup and it does. Once it loads, it automatically begins playing the presentation and loops throughout the day.
At 5:28 pm, I have an Automator script that shuts down Keynote (otherwise, the program will not let the Mac shut down). This Automator script is in iCal and is scheduled for every day.
The Automator script shuts down Keynote and a couple of minutes later, Energy Saver starts the shutdown but with the message this will take 10 minutes (!!) Then literallly 10 minutes later, with a countdown message window on the screen-- and the offer to Cancel-- the Mac-mini shuts itself off.
Why 10 minutes???
Thanks for your help in advance!

Hi,
Thy this :
1- Cut all code in the "Run AppleScript" action
2- Copy/paste this script :
on run
tell application "System Events" to shut down
end run
-- Otherwise the command "shutdown -h now" requires an admin password and must run in a do shell script

Energy Saver Shut Down Schedule Problem

I have Tiger set to Shut Down at 4:00 AM but when I wake up in the morning, the computer is still on, only it's not logged in. It is at the login screen (I have automatic login turned off). Now, I'm not sure if it's restarting the computer or simply logging out so in order to test it, I change the Shut Down time to about a minute in the future but the computer doesn't do anything! Does anyone have an idea?

Your uptime results show that the computer is not switching off.
For example,
9:56 up 9:44, 2 users, load averages: 0.23 0.24 0.23
... means it's now 9:56am and the computer has been up for 9 hours and 44 minutes.
Don't worry about the "2 users" - every individual terminal window is an additional login (unless you have actually changed the default setting). Forget about the load average too - this is just referring to how busy the CPU has been.
Another check you can run is to run this command in the terminal:
last | less
The 'last' command shows all the logins, shutdowns and reboots performed on your computer. Piping that command through 'less' just allows you to page through the results. Do you see a regular "shutdown" at 04:00?
You can start off with the obvious mistakes and check that in the Energy Saver schedule you haven't got a contradictory "Start up or wake" time set.
You also need to bear in mind that when altering the schedule, you need to reboot the Mac once for the settings to take effect, so don't expect to change the setting to 1 minute in advance and see the computer shut down at that time.
The most likely problem is that your computer has already gone to sleep before 04:00 and therefore cannot shut down (see http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1614.html). In Energy Saver, check that the slider labelled "Put the computer to sleep when it is inactive for" is all the way to the right to indicate "never".
Another common problem is that you have some software running that is preventing your computer from shutting down. Do you see any warning windows on your desktop when you come back to your computer in the morning? If any software is in the middle of an operation when the automatic shutdown commences, you should see a warning pop-up. Unless you intervene at this point, the computer will not shut down. I have occasionally come back to my Mac in the morning to find a warning window asking whether I want to save and quit or similar.
Finally, another possibility is a hidden background process that is preventing the system from shutting down. If this is the case, then it gets a bit more tricky. You need to view the system log in the terminal:
less /var/log/system.log
and look at what happens around 04:00 every day. Are there any errors that complain about shutdown?
That's all I can think of right now - my bet is that your computer is going to sleep before 4am, which prevents the automatic shutdown.
