PREVIEW WON'T PROJECT??

I was doing a Keynote presentation, and I wanted to stop that and show a PREVIEW slideshow via my projector, a new Casio, but when I tried to show the slides from the PREVIEW pdf, all I got was a black screen. I clicked slide after slide, but got nothing but black screens on the wall. I went back to Keynote and it worked normally. What??

By way of further clarification: When you have a second display (monitor, projector, whatever) connected to your Mac, you have the option to "mirror" the display or not. "Mirror" means that the display will mirror what's on your Mac's screen. Whatever's there, regardless what, will be on the external display. Two apps I know of (there may be others), KN and PP, give you the luxury of showing your presentation on the external display, but on your computer screen you have a "behind-the-scenes" look at what you're doing, like presenter notes, next/previous slide(s), time, etc., stuff you don't want your audience to see. To use this, you TURN OFF MIRRORING (uncheck the box).

  • Ram Preview won't start when Render multiple frames simultaneously enabled

    Hello everyone,
    I have an issue with rendering AE CC , with my new PC computer in Windows 8.1 pro 64 bit
    As the title says , my issue is Ram Preview won't start when Render multiple frames simultaneously enabled. Actually it starts after 8 -30 seconds depending of project complexity and the rendering is slower and skipping frames !
    12 cores with 2 GB ram each.
    When I disable the option of multiple frames simultaneously render starts ok.
    but it's really very sad that I can't use this beast of CPU in full potential. its an new intel i7 5930K , 32 Ram DDR4 2.4 Ghz
    Any advice and options would be much appreciated.
    Thanks,
    Vonzar.
    Setup:
    Windows 8.1 Pro 64 bit

    If you have any render or preview problems just turn off MP because, first, it only works with certain specific effects and codecs, and 2, it causes more problems that it solves most of the time. I only turn on MP rendering when I know for sure that it will speed up my workflow.
    You should have a multiple of 4 GB assigned to AE and Other apps and an even number of cores. If you are using MP rendering make sure that the number of actual cores used makes sense and that there are an even number of cores assigned to other applications. Most important of all, don't spend hours trying to tweak MP rendering to save a few seconds in a render. Follow these general guidelines and then run a short test to see if it works. If you project involves any temporal effects at all turn it off.
    Here is an example of the MP settings for a 4 year old Mac Mini that actually work for some projects, but most of the time it is turned off.
    I should say that I can allocate 3 GB of ram per background CPU and still see 2 as the actual CPU's that will be used but this little Mac Mini works better with 2 selected. Setting the RAM allocation to 4 GB drops Actual CPU's to 0
    BTW, I use the mac mini to record most of my tutorials because I figure that if I do a tutorial that will run OK on a Mac Mini, then anyone with an adequate system should be able to follow along without any problems.

  • PDF files created in Preview won't open in Adobe Reader

    I consider Preview to be a swiss army knife when it comes to working with PDF and graphic files. Lately (since the last OS update?) PDF files created in Preview won't open in Adobe Reader. Reader either crashes or just becomes unresponsive. I've been able to open the files in older versions of Adobe Professional but Reader 8 or 9 can't open the files. Anyone else experiencing these problems?

    Yes. We noticed this problem after upgrading to 10.6.7. When we made a PDF from Word 2011 or even Text Edit through Adobe's "Save as Adobe PDF" it would hang. When we made a PDF using Apple's "Save as PDF" it would lock up Acrobat Pro 9 and also Acrobat Pro X. NOTE that this only happened using Adobe OTF fonts.
    I posted this problem on Adobe's forum and received a message from admin there that this was caused by a change in font handling with Apple's 10.6.7 update.
    As of yet, no solution has been posted. I also received a message from Adobe's Tech Support that it was forwarded to their engineers.
    Still waiting.

  • I can't seem to get rid of OR use Adobe Reader after I let it into Safari 7.  How do I get to the point where Reader is not my preferred anything, but can still be used if Preview won't open something?

    I can't seem to get rid of OR use Adobe Reader after I let it into Safari 7.  How do I get to the point where Reader is not my preferred anything, but can still be used if Preview won't open something?

    Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
    Step 1
    If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.
    Step 2
    There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
    Step 3
    If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
              Safari ▹ Preferences... ▹ Security
    and check the box marked
              Allow Plug-ins
    Then click
              Manage Website Settings...
    and make any required changes to the security settings for the Adobe PDF plugin.
    Step 4
    Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
    /Library/Internet Plug-ins
    In the Finder, select
              Go ▹ Go to Folder
    from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.
    From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
    Step 5
    The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
    Step 6
    Do as in Step 4 with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

  • I received a .pdf document as an attachment to an Entourage Email. It refuse to print on my HP4050N printer which is otherwise performing as advertised. Printing fron the desktop, Adobe 9.4.4 nor Preview won't work. I have a PowerPC G5, OS 10.4.11.

    I think the file has somehow been corrupted. Can you have the person that sent it to you send another copy?

  • Preview won't print

    Preview won't print most PDF files that I've created using the 'Save as PDF' in the print dialog window. It just spits out blank pages. If I select 'Preview' it show the document correctly but telling it to Print just produces a lot of blank pages.
    This also happens to many PDF files that I've downloaded and were not created on my machine.
    Any ideas what the problem is?
    Thanks in advance

    Sounds like a driver issue. Has this ever worked or is this the first time you've tried? I'd test in a new user to be sure it isn't a corrupt Preview preference (which you could isolate in ~/Library/Preferences/). If the same thing happens in a new user, I'd say it's the printer settings. Try resetting the printer system via Printer Setup Utility and then go back to Sys Prefs > Print & Fax to add your printer. You could need to re-install the driver as well if that doesn't resolve. Good luck!

  • Preview won't open.  It will open when in test mode but not in my user mode.\

    I'm running Yosemite 10.10.2.  My Preview won't open.  I followed Linc's advice and removed many files but Preview still won't open.  I have tried cold booting to no avail. 

    I just figured out how to open Preview...... Open Finder>Documents>click on any PDF or JPEG.  Preview opens.  Now, if I could only get it to open from the Dock.

  • I cant' print using firefox. print preview won't display, won't print, printing dialog box won't display, etc

    Seems like since I updated to firefox 5 I can't print web pages, print preview won't work. I click on the print option under file and nothing displays or prints.

    Try the Firefox SafeMode and see if you can initiate printing from within Firefox. <br />
    ''A troubleshooting mode, which disables most Add-ons.'' <br />
    ''(If you're not using it, switch to the Default Theme.)''
    # You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
    # Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
    If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

  • Preview won't load

    I'm running Mavericks, version 10.10.2.  Preview won't load at all.  I am able to get it to load when in test mode but not in my own user mode.  What's up?

    10.10.2 is Yosemite.
    Do a backup.
    Quit Preview.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Remove the following. You may not find them all. Restart and test.

  • Preview won't open PICTs

    Preview will no longer open PICT files. This is since I dragged three of them simultaneously on to Preview's icon which resulted in one of them opening, but not the others. Now I can't open any, either by dragging and dropping or through File>Open, where PICTs appear greyed-out. I'm baffled. Any ideas?

    I have tried all of the above, to no avail. I suspect the problem lies in the program (Graphite) that is generating the PICTs as I have been able to replicate the problem on another PB. Preview opened one PICT and then wouldn't recognize any subsequent ones from this same source (Graphite). I have not tried opening PICTs from other sources. I will reinstall Graphite at some point, but for now, Photoshop will open the files that Preview won't.
    Thank you both for your suggestions. They have been very informative.
    ps I've just determined that Preview works correctly with files created before I first had the problem, but not with ones created since, which suggests a newfound animosity between it and Graphite. I will see if a Graphite reinstall puts them back on speaking terms.

  • Preview won't open photos

    Hi all,
    I have recently had to extract some phots from an old backup and I have recently need to look at them and find a particular one. When i double click on it it comes up with an error saying The File Could Not Be Opened, It may be damaged or use a file format that Preview doesn’t recognize. how can i fix this? i have found a folder because i read that preview won't open it without metadata. so i found the folder and there are a heap of .THM files and .JPG files in there. How can i see my photos again? Please help.
    Thanks

    Danika
    Those files that open in Preview, open them in Preview and then save them. Then try import them.

  • Preview won't open PDFs

    I have a brand new Macbook Air using OS X Mavericks and preview won't open any pdf's. It keeps saying "preview quit unexpectedly", it gives me the option of re-opening and still nothing. Not sure what to do - it's quite frustrating. Has anyone experienced this problem?

  • Preview won't open JPG image on a USB stick.

    Preview won't open 'JPG' images downloaded from a USB stick. I get this message, "The image"IMG_0091.JPG" could not be opened"  It may be damaged or use a file format that Preview doesn't recognise.
    I can see the thumbnail, but they won't open. Can I change this in some way? And, no, I can't download them again as I have erased them from the memory card, but they are saved in iphoto. 

    You can try deleting the .plist. Quit Preview first.
