Display won't sleep and screen saver won't sart

I upgraded to the new OS and the display won't sleep and screen saver won't come on. Help please.

Long shot.
Do a backup.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart the computer, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer ones.
If you want to make your user library permanently visible, run the below command in Applications/Utilities/Terminal.
chflags nohidden ~/Library/
You will need to do that after any updates.

Turn off Sleep and Screen Saver

I am trying to write my first apples script that will set my computer and display sleep and screensaver interval to "never" when I connect an external display. This is what I have so far:
tell application "System Preferences"
launch
set current pane to pane id "com.apple.preference.energysaver"
tell application "System Events"
set value of every slider of tab group 1 of window "Energy Saver" of process "System Preferences" to 50
end tell
set current pane to pane id "com.apple.preference.desktopscreeneffect"
do shell script "defaults -currentHost write com.apple.screensaver idleTime 0"
quit
end tell
The sliders in Energy Saver move, but reset when I open system preferences to check them. The screen saver interval will not change. Why can I not change its interval in the same way as the other two sliders? Any help is greatly appreciated.

I wonder if it's possible to use GUI scripting to change those system preferences that require administrator privileges. Maybe that's the reason why the settings of the Energy Saver window were not saved after you moved the sliders. However you should be able to set the computer sleep time and the display sleep time with the following line of code:
do shell script "pmset -a sleep 3 displaysleep 3" user name "yourusername" password "your_password" with administrator privileges
On the other hand, using GUI Scripting, it should be possible to change the settings of the Desktop & Screen Saver window, since its preferences don't require administrator privileges:
tell application "System Preferences"
activate
delay 1
tell application "System Events"
tell process "System Preferences"
click menu item "Desktop & Screen Saver" of menu 1 of menu bar item "View" of menu bar 1
-- delay 1
set value of value indicator 1 of slider 1 of group 1 of tab group 1 of window "Desktop & Screen Saver" to 360
end tell
end tell
end tell
However, the value of the slider is not saved either when you quit the System Preferences. I don't know why.

Require a password for sleep and screen saver

I click the box that is tick it becomes untick but when i close my laptop it ask me to enter my password in and then when i got to system prefferences it shows me the box tick when i unticked it.
Please help

Back up all data.
Quit System Preferences if it's running. Triple-click the line below to select it:
~/Library/Preferences/com.apple.screensaver.plist
Right-click or control-click the highlighted line and select Services ▹ Reveal from the contextual menu. A Finder window should open with a file selected. Move the selected file to the Desktop, leaving the window open. Relaunch System Preferences and test. If there's no change, quit again and put the file you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the file you moved.

Cannot change sleep and screen saver

I do not have File Vault activated.
I have tried all the usual tricks ( as well as the proper method) but once changed and closed the setting reverts to the original setting.
I have searched Google and many people are having this problem and no-one in Apple seems to care to resolve this issue.

Step one is to create a new admin user account, log into it, and see if the problem persists.

Screen saver won't start since Lion upgrade. Two different machines, same issue.

Screen saver won't start since Lion upgrade. Two different machines, same issue. Help

For anyone following this thread, I've found a solution to my problem. Turns out that a cute widget called FishTank appears to be the culprit. With it running in Dashboard (even when I don't see Dashboard) the Screensaver and Sleep functions don't work. I turned it off, not because I'm clever, just because I tired of it, and voilà, Screensaver and Sleep are now working. It can stay in my widgets list without any problem, it just can't be turned on. I'm going to delete it anyway, however.
Hope this points the way to solutions for some of the rest of you!
Cheers!

Computer won't sleep on Energy Saver mode

All of a sudden, the computer will not sleep while on Energy Saver mode. Any ideas on how to locate the culprit?
Thanks!

Hi, seb29. One possible culprit is a fax software setting: if the computer is set up to receive faxes, it either won't sleep at all or won't stay asleep for long. In the Print & Fax pane of System Prefs, click the Faxing tab and make sure "Receive faxes on this computer" is not checked.

Screen saver won't start

Just upgraded to 10.4.7 and my hot corners won't start the screen saver.
Checked the Security pref pane and all is properly checked. Then again, I changed nothing after installing the 10.4.7 update.
Now I can't start the screen saver with a hot corner. I even made two corners a hot corner.

Hi, Patrick.
1. Are you using a third-party mouse? If so, and you installed associated, vendor-provided software to configure the mouse, check for updates to such.
2. Is this one of the Apple-provided screen savers or a third-party screen saver? If non-Apple, test with an Apple-provided screen saver.
3. Does the screen saver start normally otherwise, i.e. after a period of inactivity?
4. Preferences for hot corners for Dashboard, Exposé, and Screen Saver are saved in the Dock's preferences, i.e. the file com.apple.dock.plist in your Home > Library > Preferences folder. These may be corrupted.1. Take a screen shot of your Dock. This is so you know how your Dock was set up before performing the next steps, as these will reset the Dock to its default configuraiton.
2. Trash the Dock preferences: com.apple.dock.plist in your Home > Library > Preferences folder.
3. Do one of the following:
• Log out, then either log back in.
• Restart your Mac, then log back in to your account.
• Quit and relaunch the Dock:a. Launch Activity Monitor.
b. Sort the list of processes in ascending order by name by clicking on the Process Name column heading.
c. Select the Dock process in the Process List.
d. Click Quit Process in the Activity Monitor toolbar.
e. Confirm your intent to quit the Dock process.
The Dock process relaunches automatically with the Dock in its default configuration.4. Reconfigure your Dock as it was using the screen shot from step 1.
5. Use System Preferences > Dock to reset your Dock preferences for Minimize, Magnification, etc.Note: If you are running any Dock "hacks" or "add ons" you might want to disable or delete these as these can contribute to Dock-related problems, such as issues with Hot Corners.
Good luck!

TS3048 Keyboard won't link and screen is locked, I cant access Bluetooth settings

My keyboard won't link and screen is locked, I cant access Bluetooth settings. What do I do?

First make sure the batteries aren't dead and that the keyboard hasn't already been paired with another device. If it hasn't, the keyboard should pair automatically when you reboot. You may have to press and hold the power button on the right side of an Apple keyboard until the LED starts flashing.
Otherwise see these support articles:
Mac mini (Mid 2011 and later) and iMac (Late 2012): Bluetooth keyboard may not pair during Setup Assistant
Apple Wireless Keyboard: Difficulty during pairing process
If you have a third-party Bluetooth keyboard, you may need a wired keyboard to complete the pairing process. It's a good idea to keep a cheap wired keyboard and mouse or trackball as backups for a desktop Mac anyway, because Bluetooth isn't completely reliable.

Screen saver won't come up

First of all, ...how do I know if my mac is Intel or PPC? I bought it 4 days ago from the apple store so whatever they're selling now a days is what I got. 27" brand new Imac straight out of the box.
Ok, ..now,...since the day I got it, the screen saver wont come on. The desktop goes to sleep but thats it. I've played around with the settings several times in response to other discussions and posts but nothing seems to work. When I "test" the screen saver it works fine, ...it's just that when my computer goes to sleep, ...thats it,....black screen. I've seen several posts stating that this is a problem with certain versions and when certain updates go through it will be fixed....yada, yada, yada. I'm no Mac-pro, I've only just recently switched from PC but this seems to be a rather frequent problem based on what i've seen posted.
Any ideas ? ...please be specific and keep it simple if possible. Assume nothing other than I know how to launch system preferences and find destop and screen saver tab.
Adam

you need to check energy saver to set up the times for the screen saver to click on for both battery and AC power...
go to system preferences, energy saver, select either battery or power adapter, optimization would be set to custom, show details, then select what time you want your screen saver to turn on...
thats it
cheers

Unexpected behaviour with "require password" and screen saver

In 10.6.x, I checked "Require password after sleep or screen saver begins" and after the invoking the screen saver (via a hot corner) moving the mouse or typing on the keyboard brought up a password dialog.
In Lion, this is what happens with the same settings:

That got posted somehow before I finished. Here is what happens:
The log in screen is displayed.
I select an account and log in.
The log in screen is displayed again.
I am logged in, but have obviously been logged out in the meantime.
This looks like a bug to me.

In System Prefereneces, when I am in Desktop and Screen Saver, I am unable to remove folders. I can click the "-" and the folder appears to be gone, but when I close and then reopen System Preferences, and open Desktop and Screen Saver, the folder reappears in the list. I have tried deleting preferences "plist" but I am totally unable to remove the folders.

I've seen one other report like yours, and I think the issue is caused by a bug, but I don't know what triggers it.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. 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.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
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. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

How can I require a password to change the "Require password after sleep or screen saver begins" setting

My son has a habit of disabling the "Require password after sleep or screen saver begins" setting whenever my wife lets him play a game on her account. I notice every other setting on the "Security & Privacy -> General" tab is protected by the lock on the lower left corner. I've never understood why this one is not. Is there any way that I can get that setting to also be controlled by the lock?

Because that setting is specific to the account currently logged in and doesn't potentially affect any others or the system itself, which is the level in general at which administrator or root access is required.

My macbook pro's desktop and screen saver is not responding

My mac book pro when started pops up a window which shows desktop and screen saver and it becomes nonresponsive, eventhough it is force quit it pops again and keeps searching for something .

You have to take the computer to the Apple store to have it checked out.

If you used system cache cleaning software it can mess up Apple software. Stop using such software. Remove Mackeeper if present using these directions:
https://discussions.apple.com/docs/DOC-3691
If you started typing something in the search field of the System Preferences, it might be hiding. Quit and reopen System Preferences to be sure it isn't hiding because it is searching for another panel.
Lastly, if none of the above apply, go to your hard drive -> System -> Library -> PreferencesPanes folder and see if it is hiding there. If it isn't, get your 10.5 installer disc that installed 10.5 on your Mac, and restore it with http://www.charlessoft.com/ 's Pacifist, and then run the 10.5.8 combo update to ensure the version matches the operating system.
