Using a Screen Saver

Hello,
I just recently got a new iMac - 21.5. Anyway, I was wondering if it was necessary to use a screen saver with this new LED screen?
Anyway, I was just wondering if it's ok to just leave it sit on the home screen for extended periods of time, or if I should set a screen saver after 20 minutes or so?
Thanks!

Hey Hoff81
Screens savers just eat into system resources and really don't do anything to extend the life of the display, if anything they do just the opposite.
Just set the display to sleep after 10 to 20 minutes +(whatever you decide)+ and/or use an Active Screen Corner in System Preferences > Expose & Spaces > Expose and put the display to sleep before you get up.

  • Screen Saver does not use selected Screen Saver when activated

    Screen Saver does not use selected Screen Saver when activated. After "Start screen saver" elapse time has been reached, a blank black full screen is displayed. I can activate the selected screen saver by using the hot corners function. Any help with this matter will be greatfully received.

    Hi again sassey,
    You're assuming correctly. Simply change the settings so that your screen saver activates before the sleep settings.
    Hope this solves your problem...

  • HT4858 How do I limit a photo from being shared on photo stream (using as screen saver on Apple TV, but don't want family photos shared in presentation)

    I am attempting to use my Apple TV and Ipad for a public presentation and want to show business pictures on the screen saver, but I don't want personal family pictures shown. Is there a way to limit these photos or set up an album for the screen saver on the presentation?

    Put the photos that you wish to use for your presentation or screensaver into a photo stream shared album and then choose that album as your screensaver in your screensaver settings.

  • Can't use my screen saver while using front row for music?

    When I work I have my computer on the desk next to me, usually I have music playing and my very large image library running through my screen saver. I used to be able to start up my music using the remote, going through front row. I'd start up the music and back out. It would just return to my screen saver at that point.
    Now when I try to do that, I can't back out of front row without also backing out of my music. It's kind of annoying... I mean, I can just start up itunes and go from there, but it was a nice function that I really got used to.
    Does anyone know of a setting that I can adjust that would allow me to do this again?
    Thanks

    The way it used to work, I'd already have my screen saver running, I'd open front row from my remote, and just start up itunes through that. I'd never actually see the itunes app because it would just open on the toolbar. As soon as I backed out of front row it would automatically go right back to the screen saver while still playing my music. All from across the room.
    Now I have to go over to my computer, open up itunes, start that up, windowshade it to the dock, then hot corner my screen saver again. All sitting right at the desk.
    It was a nice convenience. I don't understand the loss. At least give us the option to open it in the background in preferences. I've always appreciated the fact that Apple let us use our computers the way we like. This just seems counterintuitive.

  • Locating pictures used in Screen Saver (Previously loaded)

    I've noticed that the options for screen savers such as Beach, Cosmos, and Abstract are quite interesting and was wondering if it's possible to locate the folder where these images are stored. I would like to use them as a background if it's even possible to discover their location. Thanks.

    Hi there,
    this is an easy one
    Just go to "/System/Library/ScreenSavers/" and right click on one of the
    screen savers. You will see a contextual menu, showing an entry "Show contents".
    Select that and then in the open package go to "/Contents/Resources/" and you have
    access to all the pictures the screen saver uses.
    Kind regards,
    Robert

  • Can not use default screen saver with this version of Mac OS X

    Hello,
    I created a 10.6.4 image on a Mac Pro that I have installed on a new 27" iMac. Every thing works fine, as expected, except the screen savers (all Apple default). All screen savers appear in the list when booted off the Mac Pro, but when booted off the iMac, all but 2 disappear (Computer Name and Flurry). Also, the ones listed under Pictures show up, but when I try to use one it says "Can not use 'screen saver name' with this version of Mac OS X - Contact your vendor."
    Also, the flurry screen saver runs extremely slow.
    Unfortunately, I don't have another iMac to compare versions with, but I've compared with a new Macbook Pro and they are exactly the same. Is there a cache or a pref I can flush?

    The old screensavers were about the first things that didn't work when moving to Snow Leopard, so my guess would be the iMac is booting in 32-bit vs 64-bit mode (or whichever mode is incompatible with your screensavers).

  • Will I be able to use Forest screen saver in Yosemite?

    In preparing to upgrade to Yosemite on an iMac at home running OS X 10.6.8, I discovered and started using the Forest screen saver under OS 10.6.8.
    Is there any way for me to use the same screen saver after the upgrade to Yosemite?
    I noticed on my new office iMac that Yosemite did not offer the desktop called Aqua Blue that I've used on all of my computers up to Mavericks. Aqua Blue was available under Mavericks, but I couldn't find it under Yosemite.

    I'll continue to answer my own question: Success!! Yes I can use the Forest.slideSaver jpgs within the Yosemite Screen Saver.
    First,  I made a backup copy of the System/Library/Screen Savers folder to another location on the OS 10.6.8 computer’s HD prior to upgrading to Yosemite. I did this by holding down the option key while dragging the entire System/Library/Screen Savers folder to another location.
    The Yosemite upgrade went without a hitch, that I can see. Indeed, Yosemite is much more responsive on this 2011 iMac (w/ 8GB RAM) than Mavericks is on a mid-21012 MacBookPro (w/ 4GB RAM). I still have several applications that need to be updated to run under Yosemite, but that’s for the future.
    All of the following was done under Yosemite as the OS.
       A Google search for the .slideSaver file format provided a MacWorld Hint of how to create your own screensaver, intended for a previous version of the OS. This involved the use of Terminal. I am not comfortable with UNIX, so I did not follow its instructions except for learning about doing a right-click (control-click) on the file to view its contents. Worked like a charm. I was then able to Show Package Contents which enabled my viewing of the Contents/Resources/ where all of the jpgs resided. I used shift-select to only select the desired jpgs within that Resources folder and then option-drag to make a copy of the jpgs into another folder on the HD.
       Within Yosemite's System Preferences/Desktop & Screen Saver one has the ability to select a folder somewhere on the HD that is the source of the images that will be used for the screen saver. I selected my newly created folder of “Forest jpgs”  with Shuffle slide order checked and set it to use the Ken Burns version.
       Voila! I’ve replicated the Forest.slideSaver screen saver from Snow Leopard on Yosemite.

  • Leaving iChat open while using the screen saver?

    I like to put my computer in screen saver mode and lock it when I'm away from my desk but don't want iChat to log off. Any ways to leave it from doing so? Thanks.

    Hi!
    iChat will stay logged in as long as there is an active internet connection. To prevent a disconnection, prevent your mac from "Going to Sleep", and you should stay online.

  • How Do I Create a Screen Saver That Uses Shared Photos??

    I have a pretty simple request here, or at least I think it should be pretty simple. My family uses a shared photo stream so that we can all see what everybody is up to without sending a bunch of individual messages.
    I'm going to use a screen saver that displays photos but the tricky part is...I'd like the family's shared stream to be the source for all the photos.
    Previously, I went into iPhoto and just selected all of the photos from the stream, dragged them into a desktop folder, and set this as the source for the screen saver. The only problem with this method is that whenever a new photo is added, it won't show up in the screen saver (obviously). That's why I'd like to set the shared photos as the source.
    Is there a simple way to do this and set the shared photos as the screen saver source??    I would even settle for doing the alternate method that I described in the last paragraph, but I can't even figure out how to do this with the new "Photos" app...
    PLEASE HELP!! Thanks in advance...
    Pete

    Pete, setting the screensaver is a matter of patience, the menus are very slow, if you just set up the system and the spotlight index has still to be recreated.
    But you should be able to it this way:
    Open the Desktop&Screensaver System preferences, select the Screensaver tab.
    In the left pane select a screensaver template for slideshows.
    In the right pane select the Source menu.
    Now wait and have a cup of coffee, while "Loading is showing"
    Then select the last item "Photo Library".
    Wait again, until your current photo libraries are shown.
    Select the Photos library,
    Select the Shared section and your shared family stream.

  • Using Screen Saver & a projector

    I have a Canon 40d with a wft-e3 wireless transmitter attached. I wanting to know how to get the pictures I take to project to a slide show dynamically. Is there any type of software that will do this? I am working with a Mac Book Pro 10.5 OS. The best way to describe what I want to be able to do is to use the screen saver functions on the mac as an example. You know how you can go into system preferences and select a folder with pictures and have that as your screen saver? Well, I want to be able to shoot pictures on the fly and have those pictures sent wirelessly to this folder and have the screen saver folder update automagically and then have the screen saver projected out onto a screen. Is this possible??????? Please help. Thanks

    Interesting, but thankfully there are much easier ways of doing it!

  • Screen Saver using A3 Library

    Not major, but after upgrading to A3, I noticed that in SL System Preferences>Desktop & Screen Saver, it no longer recognizes my Aperture library. With A2, I was able to have the screen saver cycle through my Aperture library. Any ideas?

    Right, in Desktop there's an "Aperture" line item that doesn't do anything. In Screen Saver, there's no trace of Aperture.
    This is actually a problem for me as I tend to use the screen saver to let images "sink in" before I publish an album.
    I'm guessing this will get sorted in 10.6.3.

  • Screen saver lag in loading photos from new folder

    I use my screen saver to display the family photos in a side show. I have several thousand photos in several folders. I have noticed that whenever I want to change the folder used as the side show source, it takes the Screen Saver Preference pane a very long time to respond. It is as if it is scanning all the photos in the currently assigned folder in order to display them in the preview window provided, and it gets so dogged down doing that it can't respond to my clicks on the Choose Folder option. This is puzzling because when I move my mouse cursor to the upper left corner of my screen to activate the screen saver, it only takes a few seconds to begin displaying photos, even with iTunes and other apps running. But when I open the Screen Saver Preference Pane just to change the source folder or to make any other simple change in options (pan and zoom, time to activate screen saver, etc.) it bogs down completely for 2-3 minutes. This makes no sense to me -- if the OS can get the screen saver side show going on a folder with several thousand photos in just seconds when the hot corner is used to activate it, why does it take the Preference Pane version so long to load the very same photos in a preview window? The problem is so bad, that I rarely bother to change source folders now. Which is a shame, because the side show program does a stellar job displaying photos -- at least once it gets around to it! A possible solution would be to give the user the option to suppress previewing of images. I have suggested this to Apple in several emails, and with each update to the OS I hope to find the problem corrected. So far, no cigar.
    As long as I'm at it, I'd like to make my annual request that Apple to make the Screen Saver side show a stand-alone application. My reasons, partly taken from an earlier post, are as follows. The built-in side show provided by Apple via the Screen Saver Preference Pane does a fantastic job of displaying even low-resolution photos in full-screen mode (especially with pan and zoom activated) without the photo appearing excessively blurry or pixelized. I don't know how the Apple programmers do it, but the photos displayed by the screen saver seem crisper and sharper than the same photos displayed by Preview or Photoshop. This may partly be due to an illusion created by the pan and zoom -- the expansion and shifting of the image on the screen causes the mind to focus on the signal, which is consistent from frame to frame, as opposed to the noise (pixelization) which varies somewhat randomly. I think there is some kind of perceptual averaging process that allows the mind to perceive the underlying true image, despite the low resolution.
    Be that as it may, I love the iMac screen saver. But I can't get control of it because it is not a stand-alone app. If the side show were available as stand-alone application it would probably have other features such as the ability to pause, go backward or forward, set the duration of each photo, select background music, etc. These would be in addition to the pan and zoom options already offered by the Screen Saver Preference Pane. And unlike the Preference Pane, selecting a new folder for the side show would (hopefully) not dog the machine completely down.
    I am aware that side show capability is available within iPhoto and also at the FINDER level when using Spotlight to search for images. But again, none of these are stand alone apps, they all work a little differently, and no one of them does everything you need. How about just having an app called Slideshow (or iSlideshow)?
    Does anyone else see a need for this?

    I have several thousand photos in several folders. I have noticed that whenever I want to change the folder used as the side show source, it takes the Screen Saver Preference pane a very long time to respond. It is as if it is scanning all the photos in the currently assigned folder in order to display them in the preview window provided, and it gets so dogged down doing that it can't respond to my clicks on the Choose Folder option.
    Assuming you don't want to redistribute your photos into a greater number of folders or subfolders so there would be fewer in each folder to process, you could try a workaround. Try moving your currently-assigned folder to your desktop temporarily, before opening the Screen Saver preference pane. If the preference pane can't find the old folder, it may immediately ask you to choose a new one. You could hopefully then do so, close the preference pane, and then put back the old folder.
    It's my understanding that there will be no future updates to Tiger, only security fixes.

  • Photos Screen saver problems in Windows 7

    Photos screen saver crashes most of the time when I move the mouse to exit.
    Round circle, this application is not responding etc.
    This is pc  upgraded from Vista

    Hi sven253,
    Is there any third party screen saver software installed? If so, please uninstall it and see if the issue occurs.
    As Magon mentioned, Clean Boot is a good method to check if the issue is related to third party software and services. If the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue.
    Also, please test the Sample Pictures came with Windows 7 and see if the issue exists:
    1.     Right click on the Desktop and then click Personalize.
    2.     Click Screen Saver.
    3.     Select Photos and then click Settings…
    4.     Browse the folder to C:\Users\Public\Pictures\Sample Pictures
    5.     Click Save.
    6.     Click OK.
    What is the result? If the issue persists, please test if the issue occurs using other screen saver, such as 3D Text or Bubbles. However, if the issue does not occur using Sample Pictures, could you please provide the following information for further research?
    ·          What is the file types you are using? Are they .jpg file or .bmp files?
    ·          What are the file size of each photo?
    ·          How many files are there in photo folder?
    ·          When did the issue first occur? Did it occur after installing certain software or changing some hardware?
    Hope this helps.
    Regards,
    Linda

  • Random Screen Saver: How to remove iPhoto Library ?

    When you tag "Use Random Screen Saver" in the System Preference Pane, the Screen Saver browses all the iPhoto Library.
    How is it possible to get rid of that, as the "minus" button is not working (anyway it is grey for all the directories in the list) ?
    iPhoto Library does not appear in the System/Preferences/Screen Savers as well.
    Is this some bug from Snow Leopard ?

    If you want to report this issue to Apple's engineering, send a bug report or an enhancement request via its Bug Reporter system. To do this, join the Apple Developer Connection (ADC)—it's free and available for all Mac users and gets you a look at some development software. Since you already have an Apple username/ID, use that. Once a member, go to Apple BugReporter and file your bug report or enhancement request. The nice thing with this procedure over submitting feedback is that you get a response and a follow-up number; thus, starting a dialog with engineering.
