Preview.app freezes dock and command + tab

Everytime I open the Preview.app it completely freezes the tab dock and order for a few minutes. I can switch between applications using the mouse and launch applications using spotlight search. But I can't control the dock or use the command + tab.

On a different user account, I don't have this problem. But I prefer not to set up a new user and copy all content and settings to it. I tried to start using dtrace, but the system, I cannot use it. I tried to delete the files ~ / Library/Preferences/com.apple.preview*, but that didn't help either.

Anyone here have a tip what I can try? Nothing appears at the top and monitor activity. And there is no program that does not respond according to the menu force quit. Close the application overview does not make the problem go away. It goes away by itself after a few minutes. So far, I have not found any other piece of software that causes this, only the Preview.app.

Looks like a malware problem.

  • Open photo of Photos in the Preview app? Need info GPS and maps!

    Hello!

    I write trip review and to see where my photo was taken (in the maps application), and what is digital gps coordinates for each image.

    Search on google - go, I got that via this pic of opening in 'Preview' app.

    But - I have all my pic in Photos app (automatically imported from my iphone to macbook pro Mac OS sierra).

    so, I can export all the photos, I need, in a specific folder and then, from there, open it in the finder and get my info, of course - but looks silly, I think.

    as I already have this pich in Photos - photo can I somehow open directly from Photos Preview app?

    or obtain the gps position open, where this picture is taken in cards programm (not this small window, which is in the Photos, but wide, Maps application) / and obtain the coordinates of the gps directly via the Photos app?

    Thanks in advance.

    Use the media browser in preview - in the open window on the left down - media = == > photos == > Photos

    or even more appropriate is to buy external editors for extension of Photos in the App store ($0.99) and you can view the pictures in preview when using the hotos

  • Preview App not displaying not updated content, even after 30 seconds and closing/repoening

    I created and installed a preview app and reading some of the other comments here on this topic. I added .article files to my collection of high level and published. No bubble update appears after closing and opening the app within minutes. Do I need to click on the preview icon in the upper right corner of the Web portal whenever I want to get a preview of the changes on the device? I also tried, with no update was successful. If I delete the app and reinstall, my content to date is then displayed.

    I had success lately overview my content updated in the application preview. What I did differently, was 'Unpublish' the content I was updating to be read in the preview application until I click the button Preview in the user interface.

  • Why is el capitan slowing/freezing applications I try to use on my macbook pro 13 "2010 mid? 16 minutes to open safari and 2 tabs, another 1/2 hour to load. missed reading iTunes, imovie took 12 hours to import a clip, then en

    El capitan sank my already very usable macbook pro 13 "! EACH application is slowed until almost uselessness, takes almost five minutes to wake up to the top/connect to wifi after sleep, a lot of problems with playback of streaming audio and audio itunes, making my virtually inaccessible whole itunes library. Stuck in the date and time, just a general nightmare.

    A took 15 minutes to open safari and two tabs, more than an hour to open chrome, imovie has spent more than 12 hours to load a video from my phone, and then frozen.

    I do not usually post in forums or discussion because I don't usually have something to contribute, but I wish that I had listened to the warnings of this despicable OS. I feel forced into it. I feel so angry that I can't access simple features of my audio and video programs that I have used so much before this debacle.

    So far, it's worse than Windows Vista. Way worse.

    If anyone has any suggestions, I would be grateful, but I just try to find an older OSX will not treat my computer as if it was a cell grocery store to throw.

  • Preview.app crashes at startup. Reinstall/Repair anyway?

    For about 8 months now, I've been unable to use Preview.app. It is on OS X 10.10.5.

    When I open it nothing with Preview (can be a file PDF or JPG or other) it crashes immediately. When I try to open the preview directly (not open anything with it) it opens, but if I then try file > open anything with her, same thing. From time to time, it will prompt me with:

    The last time that you opened an excerpt, it unexpectedly while the reopening of windows. You want to try to reopen his windows again?

    If you choose not to reopen Windows, you may need to open and position windows.

    I tried a few months to fix, but did not. I don't remember that I tried and do not seem to be able to find the message I thought I posted about this at the time. So I have a new go at it.

    Is it possible to repair or to reinstall or reset an excerpt?

    This happens to another user?

    Create a new user and see if the problem still exists to ensure that this is not a problem with your username.

    Otherwise, to reinstall an application that comes with os x, you must reinstall the operating system completely.

    Restart the computer and hold down the command + R immediately, then reinstall Yosemite.

  • Preview app - Instant Alpha tool does not appear in the toolbar of the Markup

    Mac OS X 10.11.4 Preview app

    I am trying to remove a background from a PDF file. I used to be able to do it with instant Alpha Preview tool. I checked under Preview Help and it still says to do that using the instant Alpha tool, that she should appear when you select show a markup toolbar. But he's not here. All that appears is a rectangular selection tool. The instant Alpha tool are removed from the latest version of preview in Mac OS X El Capitan 10.11.4?

  • Preview.app stuck on the first page of the PDF in single page mode

    I regularly Preview.app view PDF files and want to use the "Single Page" function to display an entire page at one time. I have 'Single Page' display set as the default behavior.

    Lately when I open a PDF file, they properly open the first page, but I am unable to navigate to another page via the drop-down page, touch up/down arrow. If the PDF file has a table of contents, I am able to go beyond the first page through it and then proceed to navigate normally. If it is not a table of contents, the only solution is to continuous scrolling mode and continue to navigate beyond the first page.

    It's very annoying! Unfortunately, I can't remember where this started happening. It could be when I upgraded to MacOS Sierra, but I can't confirm.

    Everyone else see this behavior?

    Hold down the Option/ALT key, then use the cursor to the TOP or to the BOTTOM of the key.

  • With Preview.app permission issues

    Hello

    Given that I've updated for macOS 10.12 I can't change any photo on my desk with Preview.app.

    When I do a print screen or drag a picture of Mail.app on my desk and start to edit, I get a notice in Preview.app that the original document is not editable and a duplicate has been created.

    If I copy the same exact file in my documents folder I can modify it. But when I add running on the file on my desktop, I can change it as well. But why files rwx for me on my desktop but rw in the folder my documents is sufficient?

    What is the problem with my desktop folder or files contained in it?

    Files and folders are set to my username and the personal group.

    Closing and opening preview or restart the computer may fix. Otherwise, close preview, open a Terminal window and type/paste:

    RM - r ~/Library/Containers/com.apple.Preview

  • Sierra affecting Preview App PDF edition

    Hi all

    I had my company created as an editable PDF invoice.  View this model of invoice 3 years by Preview app, I was able to easily change addresses of clients, invoice details, amount of fees, taxes, etc.  When finished I would export a copy of the Bill, which would be a version not editable I send to my clients.

    Since the update to Sierra last week, I am not able to use the preview or any other application modify my invoice template.  As I'm typing in text information, some lines of previous text disappear when exporting some or most of the text in the new version disappeared, there is a change in text from the white to the black color in the lower area of the fees of $ final.

    After many attempts, a customer told me on this subject - somehow, I was able to export a version they could read in Adobe Acrobat format, but they have also commented that Acrobat showed the following warning: there is an error on this page.  Acrobat may not display the page correctly.  Please contact the person who created the PDF document to correct the problem.

    After 3 years of working perfectly, now my Bill is haunted! Corrections or suggestions would be greatly appreciated!

    Kind regards

    Any who have the same problem or know how to get out them of the docking station?

  • command - tab problem

    Hello

    On El Capitan with a Macbook 12 "machine, the control function + tab doesn't work correctly (as work for example on my old desktop iMac with El Capitan...)

    What happens is that when I try to switch to a different application, by using the command - tab, the application becomes active, but without having to open the appropriate window: basically, nothing happens, only the application menu appears in the tab order. This makes it really unnecessary the whole order - function tab.

    Does anyone have an idea why this happens and how to fix it?

    See you soon,.

  • Command + tab to open the Finder window does not

    Sorry to post this again - the first accidentally got marked as resolved, but it is not and I still need help.

    I recently installed at El Capitan on my iMac, and now, when I use the command + tab to toggle an application by opening a window of Finder, I get that the Finder menu bar. The open Finder window is located in the window menu, and I choose to see it and use it. Before the upgrade, command-tab would be near the top of the Finder window currently open and active. How do I get it to behave as it did before? I HATE having to select the window menu item! AND when I select the window from the window menu, the bar menu auto mask, that I also hate. Automatic masking occurs only in the Finder, and he is not selected in the settings of my Apple.

    Help! Thanks in advance.

    I think you have Finder mode full-screen. I do not use full screen at all, so I'm not really familiar with it, but what seems to work for me was to switch to Finder and select the window from the window menu, and then press ESC to exit full-screen.
