Weird black lines around windows

Macbook Pro 15in. Mid 2010
Processor: 2.4 GHz Intel Core i5
Memory: 4 GB 1067 MHz DDR3
Graphics: Intel HD Graphics 288 MB
Software: OS X 10.9.1 (13B42)
Hey everyone,
Whenever I open different apps, (Word, Preview, Reminders, etc.) or when I hover over apps to select them, I get these weird black lines that outline the window. I have reset the PRAM before and it fixed it temporarily, but then it returned. If I go to "displays" and switch from 1440 x 900 to 1344 x 840, and then switch it back, it gets rid of the black lines. Any ideas?? I've included a photo of what it looks like. As you can see, the black lines on the left of the window is what I am talking about. Any ideas or information will be greatly appreciated. EDIT: This did not occur until after I had upgraded to Mavericks when it came out.

Hello S:
Welcome to Apple discussions.
i think the cause could have been a finder add-on i used for a while (totalfinder), since it was an alpha build.
Almost assuredly (I will not give a lecture on Alpha or Beta software). Did you uninstall it somehow?
In any event, you have a couple of options.
Easiest first - trash a couple of preference files (com.apple.dock.plist and com.apple.finder.plist) and restart.
If that does not work, I would restore (hopefully you have one) the system to a point before you added the Alpha software.

Black line around window in Mail

A mysterious black line (box) has appeared around the window in Mail. I can click and drag this box but have no idea how to get rid of it. If I click on it, it actually closes the window. Dragging it re-sizes the box. How do I restore back to "normal" mode please?

Dunno why clicking it closes the window, but try pressing command-F5 to turn off VoiceOver.

Black lines around fields I tab to incl. button, p-d menus

Something weird is going on with my computer: there's a black square around the active field in every app on my PowerBook. For example, if I open a new window in Mail, there's a black line around the New Message icon (the upper-left-most icon in my toolbar configuration). When I start typing in the address field, the black line moves to that field. If I hit Tab, the black line goes to "cc:" then "subject" then the "add bcc..." pulldown menu, then the "account" and finally "signature" pulldown menus, before going to the message window. It's basically the same thing in every app-- an ugly square of thick black lines around every active field in the app I'm working in. I poked around Universal Access in System Prefs & nothing helped. I think my daughter was playing with the computer & did something to it but she's only a year old so I can't ask her! Please help me get rid of this thing! Thanks

Hi There
Have you tried System Preferences > Universal Access > Seeing > Voiceover:(Check) and click 'off'.
Worked for me!

Black Line around thumbs

Any idea why I am getting a black line around rows of thumbnails. On a Mac/Intell CS3, latest update of Bridge as well.
I can open fine, just curious about the black line.
Thanks in advance

This means that the cache and/or preview has not build itself. Try the purge cache for folder using tools - cache - purge cache for folder.
Depending on the number of files it takes less or more time to rebuild. See also the info down left in the window. This shows the number of files visible and hidden, and if building cache and preview the two arrows are acting like a spinning wheel and also a percentage is showing how much work is done.

Have placed video-when previewed there are sometimes heavy black lines around the image. If I place white rectangles in front, the black is hidden in Author, but when I preview the black lines are still there..How to use white rectangles to mask edges?

Thin black line around mask when placed in Final Cut Pro

After upgrading all to the latest version of the Pro suite, I'm getting a thin--pixel-wide-black line around my Motion masks when placed back in Final cut pro. Is anyone else seeing this?

Try this:
Open you media bin (F5) click on the "Media" tab at the top and find the "offending file". Click on the file and go to your Inspector-->Media. Under the "Alpha Type" drop-down menu, select "Premultiplied - Black" (or white or color) and see if that fixes it. I was having a similar issue with a white line appearing and this fixed it.
Good luck.

Why & remove: thin black line around new image?

Hi there.
PS CS3 (10.0.1)
Why does PS automatically make a thin black line around any new image and how can I set PS not to do this?
You can please have a look here:
http://www.josua.co.za/graphics/josua-banner.jpg
I will really appreciate your help.
Regards,
Deon

Thank you for replying to my question.
You are 100% right ... I have made the canvas a bit larger and there is no line.
BUT, why is there a line around the image when viewing in a browser? I dont' want it there and this is the first time I have this problem.
Thank you for your time & help.

Deon

Weird black lines

i had my whole logicboard replaced because there were weird things happening like my whole safari page looking messed up, the menu sometimes being all over and weird, black lines in the left side corner.
2 days ago (a week after replacement) i had one problem where everything was messed up and when clicking anything on the dock it logged you out!?
restarting it seemed to fix this. but the black lines in the corner came back today and i realized it happens after a growl notification pops up. when it fades away it sometimes leaves lines.
is this the OS? or is this growl? or is this something i should bring my computer in for again?

Black frame around windows

Hi all,
recently upgraded to SL. And, from time to time, I have black frames around my windows where the shadow should be viewable.
Anyone else having this problem?

I was able to narrow down the issue, these weird black frames only appear when or after I have used an application that requires 3d graphics, such as Maya.
Sounds like your system can't keep up with the rendering required...try to run Maya alone, right after a reboot and be sure to have sufficient free space on the HD.

PDF exporting with thin black lines around some images

Hi there,
I have spent A LOT of time making a custom SAVE THE DATE card and I cannot find a solution to this problem. When I am working in the document, I do not see thin borders around any of the images but when I export to PDF they show up. I have NO BORDERS selected for all images in the document and cannot figure out why they keep showing up after export.
I have attached a screen grab of what the document looks like when I am working on it, and another one of what it looks like after export. I am using Pages 5.2.2 and OS X version 10.9.5
I need to order these SAVE THE DATES by tomorrow to take advantage of the 60% off! Thanks so much for your help!

I am seeing this same problem in a family newsletter I've created. The lines do not show up in Pages, but when I export to pdf (or print to pdf), the lines appear. When I print the document, no lines appear.
Here's what the top of the newsletter looks like - the black lines show up on all the pages, and in the beige-covered overlay, crosshatching is visible. The template I'm using was in existence two years ago, but doesn't seem to exist in Pages anymore. Would that have anything to do with the lines showing up?
I also found this link, but can't apply any of the suggested fixes, since they apply to Adobe: <http://helpx.adobe.com/indesign/kb/thin-white-dark-lines-stitching.html>.

Bizarre lines around windows; strange screen problems

My Macbook has been acting strange lately. I'm attaching a few images so you can see what's happening with my display. Sometimes, after I exit a program and return to the desktop, I get strange patches of white/gray boxes on the screen. Logging off and back in clears the boxes. Now I have vertical lines around all my open windows.
Any ideas?

That doesn't sound good. Run the hardware test that came with your computer:
http://docs.info.apple.com/article.html?artnum=303081
If nothing appears there, do you have any software that modifies the operating system that you aren't sure has been tested with the operating system release you have? When specs call for 10.5.x and higher, they do not mean 10.6.0, 10.6.1, or 10.5.2 through 10.5.8.

Black box around window screenshots?

Hi guys,
I'm using 10.6.2 SL and whenever I take a screenshot of a window with Shift Apple 4 Space, I get this ugly black box around the window.
Here is an example.
Before, the screenshot would have a nice shadow. It used to look like this.
Was this intentional? Or is this a glitch?
Thanks
Sohrob

That behavior's abnormal. Start with a search for *screenshot black border* and peruse the hits. If no luck, create a new admin user account, log into it, and see if the problem persists.
