Is there a lock screen command in OS X similar to Screen Lock in Windows?

I want to lock screen for a brief period of time, and didnt want to log out or shut down the system.
Is there a lock screen command for this, so that I can lock it and unlock whenever I need?
Or I am wondering if I can log out without closing the application so that when I log in back, I get to the application and continue working from whereever I left.
I dont want to close the application and be able to lock or logout the user. Please suggest me some ideas.
Thanks,
Gopinath

Open the Security pane of System Preferences and check the box to require the password to wake from sleep or screen saver. In the Desktop & Screen Saver pane, set up the screen saver to activate when the mouse is at a specific corner. The screen saver can be unlocked with the password of the person who is logged in to the machine or with any administrator password.

    Your best bet is to take in and have it looked over the counter. There is no charge for the Genius bar to assess
    the problem.
    Either the screen / cable / connection / or GPU.
    Not much else you can do.

    No, sounds like when you dropped it an cracked the screen it may have also damaged the logic board or the repair person damaged a cable.

    I have a apple ipod touch but recently I restored all the settings, as well as the applications. But now I am not able to add songs to it. There is blank screen that shows the symbol like to connect to itunes first. I'm not able to use that... Please help

    The iPod's firmware is corrupt. You'll need to restore it again in iTunes. If necessary, place the iPod in recovery mode for iTunes to recognize the device. Use the instructions in this Apple support document to walk you through the process of placing the iPod Touch into recovery mode.

    I recently bought a new tower with windows 8.1 everything was fine until yesterday when I went to watch a video that someone had posted, the sound was there but the screen was all green everything I try to watch has a green screen, I have gotten rid of the green screen but now the video won't load to watch. it tells me I have to upgrade flash player but my computer tells me its already embedded or something like that in windows 8.1. can you help.@marks93255255 or [email protected]!

    If other devices can connect to the network without problems, it means that the router can provide wireless internet. For this situation, an isolation process is needed to be able to find a fix.
    Was the computer tested to connect through Wi-Fi before you bought it?
    Did you do Mac address filter on your router?
    Make sure that the router is using WPA/WPA2 or WPA2 encryption type just like what Chester has recommended. If your router is already set to that security type, you may test by disabling the wireless security of the WI-Fi router. Check if it will connect or not.
    Another thing to check is the properties of your wireless connection. To do that, Go to Network and Sharing center > Click change adapter settings > right click “Wireless” > go to Properties> click Internet protocol IPV4> check the Properties button below > make sure that it’s set to both Obtain IP automatically and Obtain DNS server automatically.

  • I recently thought I was updating my Safari browser. When completed, I put all those little files that were on the desktop into the trash. Now my trash is saying it can't be emptied because there are locked files and I don't know how to unlock them

    I recently thought I was updating my Safari browser. When completed, I put all those little files that were on the desktop into the trash. Now my trash is saying it can't be emptied because there are locked files and I don't know how to unlock them or get them out of my trash and they keep multiplying. And to make matters worse, I tried renaming them as pdf files thinking that might do the trick.

    oh boy ! I'd ask you if you knew what kind of files they were or where they came from, but I don't think you could help me a bunch. Try going to the Utilities folder and running Disk Utilities.  If you want to empty the Trash and it won't empty, go to the finder and choose "secure Empty trash". Worse case scenario-you may have to reinstall Snow Leopard, but I don't know what else to suggest. If you have a DVD of Snow Leopard, boot up from that,  and reinstall the OS. This will not touch the stuff you have on your Hard Drive, then you can update from 10.6 to 10.6.8, otherwise Onyx? Maybe those files are part of the OS which needs them to keep running.  if you hold down the Shift key on reboot, you can reboot in Safe mode and maybe you can take the files out of the trash that way
    good luck

    If the Reset didn't work, you'll need to do a Restore.
    From iTunes, select the iPad and then select the Summary tab.  Follow directions for Restore.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finished, you will be asked if you wish the contents of iTunes to be copied to the iPad.

  • Is there an on-screen touch feature that can be purchased to save wear and tear on the home/escape button?

    Is there an on-screen touch feature for iPad 2 that will save wear and tear on the home/escape button?  If so, what's it called and where can I buy it?

    And if you are running iOS 5, you can enable Multitasking Gestures in the General settings. This enables you to quit out of an app by just pinching with four or five fingers. That saves a lot of use of the Home button.
    Regards.

    Hi there ajsupprt,
    It sounds like you may need to update the version of Java installed on your computer. Take a look at the article below for more information.

  • Is there a split screen option

    so I can have 2 app going at once?

    No. There is no split screen or two windows option on the iPad.

  • Type "purge" in Terminal and get:   -bash: purge: command not found   Is there another built-in command to clear memory leaks?   want to clear memory periodically

    I have 10.6.8.  When I type "purge" in Terminal I get:   -bash: purge: command not found   Is there another built-in command to clear memory leaks?   I have FreeMemory (works well) and considering FreeMemory Pro, to clear memory periodically, say every 20 minutes, or preferably when a threshold is reached, say when only 100MB is available.

    To get purge to work you need to install Xcode from Optional Installs on the 10.6 install DVD. Also be sure you install CHUD Tools with it.
    But running purge or anything like it is pointless if within a short period of time the VM just grows back again. Sounds like you need more RAM.
    Where are the memory leaks? Just because the VM reaches a certain size doesn't necessarily mean it's from a memory leak.

  • Is there a shortcut key command for 'export'?

    Hello all,
    I'm just wondering if there is a shortcut command for the 'export' dialogue box?
    The only information I seem to be bringing up in searches is 'exporting your shortcuts' to create custom shortcut keys.
    Thanks in advance!
    Zoe

    Yes and No!
    You have to create your own using the Edit>Keyboard Shortcuts command to enter your own shortcut.

  • Is There a Move To Command?

    In all my years of using Mac OS X I should not have to ask this, but... Is there a "move to" command that can be used to move files from one location to another without dragging and dropping? Preferably one that does not involve Terminal!
    Thanks,
    Steve M.

    Is there a "move to" command that can be used to move files from one location to another without dragging and dropping?
    No, there isn't. That's one of the areas where the Windows interface has a useful feature that Mac OS X does not. Though the Windows "move to" can become rather cumbersome when you have a lot of folders, which may be why the Mac OS X designers elected not to include it.
