What are .mkv files?? What app to open them?

just found some and can't open them with anything...

These are a multimedia container file. The container can hold audio, video, fotos, etc. Probably the easiest thing is to download VLC to playback these files on your Mac.

What App will open a .pub file?

What App will open a .pub file? I tried ePub Reader and it doesn't work.

I'm not aware of anything on a Mac that will allow you to edit .pub files.
If you just need to view it, perhaps the person who sent it to you could save it as a PDF?
There are online tools that will do conversion as well, like zamzar.com. Not the best solution long-term but it may do the trick in a pinch.
But if you need to edit, I'm pretty sure you need a Windows PC with Office installed.

Firefox will not open .aspx files. I can open them with IE. What's up?

I updated Java, uninstalled and then re-installed Firefox. It will not open .aspx files. Internet explorer opens them just fine. .pdf files open fine also. Don't know?

How would I change the aspx to pdf? As far as going to the menu/applications, I don't see an aspx in the list? Sorry, but I'm pretty rank in this department. Maybe it is the website and not Firefox, although as stated, IE opens them fine.

Quick update, the duplicate of the comic-con episode downloaded succesfully, and so has the first episode of Supernatural season 8. Blue dots appear to their left in the library.
All the Vampire Diaries episodes (except the bonus comic-con double) have vanished, but I paid for them !
They're not anywhere on my harddrive either.
Which is new by the way, this is a new MacbookPro, literally set it up today.
So it would seem this is a case of purchased and pseudo-downloaded episodes that ended up beinge gobbled up by some iTunes black hole, leaving me with no money, and no episodes.
Need help, confirmed.

I cleaned up my mac and now all my applications are gone. I try to open them and it has a question mark on the app icon. Everything from System prefrences, Everything in itunes, iphoto, preview and mail? Please help

These question marks are on your dock? And you can't open applications from your dock?
If so, try this: Open a new finder window and navigate to the Applications folder in your hard disk. The applications in question should still be in there (the Applications folder). So drag each of the application icons that you want to be available on your dock from the Applications folder onto your dock, one by one. Take each of your question mark icons that are on the dock and drag them off the dock to get rid of them. See if that fixes you up.
Now, if your hard disk no longer has an Applications folder in it, or the Applications folder is empty, you are going to have to reinstall OS 10.6 then do a software update to bring you back up to OS 10.6.8. You may be able to just go to the "optional installs" folder on the installer DVD and maybe all the stock applications are there -- I don't remember and I don't have an installer DVD handy to look. That would be way easier than doing a full blown OS reinstall. Also, as I recall, if OS 10.6 was on the computer when you bought it from the store, I think there should be an "extras" DVD that has a handful of applications that could be reinstalled from it, too.

I have an old version Adobe Creative Suite 3 Design Premium. I uninstalled it from my old computer and was trying to install it on my new computer. It copied all the files but I cant open them and it doesn't ask me for my registration info, which I have.

when you were install your cs3 you should have been prompted for you serial number. were you?
if not, you probably didn't properly install cs3. copying/migrating/moving etc is problematic.
if yes, did you see any error messages during installation?
if yes, attach a screenshot of the error message.
if not, check you install logs, Troubleshoot with install logs | CS5, CS5.5, CS6, CC

I can't open any of my Word documents on my Apple Mac. The error code is EXC_CRASH (SIGABRT) and the blame module name is WordArt. The documents are still there, and I can open them on my iPad when I email them there. Any ideas?

Uhhhhh... Thank GOD... Got all of my files.
Spent some time on the phone with Apple Care... who was great to deal with but actually... not as helpful as I was hoping. It was suggested that I try DiskWarrior 4 to try to recover the files. $108 later, I had no files.
More calls with Apple Care and they were pretty sure that everything was gone since once the External drive was installed, like a moron, I let TimeMachine go ahead and back up my new MacBook... so it overwrote who knows how many gig that was my entire MacBook.
I wasn't giving up so I called Maxtor, the manufacturer of the external drive itself. They suggested file recovery software from I365... which is also a Seagate company (the makers of the drive). The suggested I simply use their demo because the demo version would find the files. If it found them, I could buy the software to restore them.
It found them! Another $129 after and I was able to restore all of them back to my old PC laptop.
NOW, I just need to figure out how to get the 50gig of HD video files off of my old laptop now and into my Mac and IMovie so I can actually make some DVDs out of them!
I get that Macs and PCs are different formats but I think it is ridiculous that formatting still means basically just wiping out or at least treating massive lots of old data as if it isn't there. There's gotta be a better way to do that.

Perform this Google search: ".dwg files on mac." The results should provide answers for you.

H.264 file - what app will open it?

I've just encoded a file in H.264 / 1080p using Compressor and none of my apps will open it. Quicktime doesn't see it, and I've tried assigning other apps to it with no luck.
The file in Finder has it listed as "exec". Can anybody help?

Don't know why QT X won't open the the h.264. (I take it you using QT X.) Try Qt 7, It should be in your Utility folder. If Qt 7 isn't in the Utility folder you need to follow these direction on how to install Qt 7:

Scroll to the top of the page for how to install Qt 7 onto Snow Leopard. To speed up the process you can download the Qt 7 installer for Snow Leopard from Apple's web site:

Despite having the File Associations in both Windows Control Panel and Firefox Options set to Windows Media Player for *.mwv files Firefox tries to open them with Foxit pdf Reader, which bombs out - what now?

Making this entry from my Linux computer which handles the situation correctly.The real situation involves only a Toshiba laptop running Windows XP.

I used this link for tiff http://www.nrl.navy.mil/content.php?P=IMAGES
QT was opening the tiff files. When going into the QT control panel Browser>Mime settings>Images-Still image files I was able to uncheck tiff, which held. I was also able to uncheck all the file types under File Types tab(Images-Still image files) in the QT control panel. However the preference would not hold. Went into Start>Set Program Access and Defaults that also was of no help.
The only way I was able to get QT to release the tiff's from the website I posted was to go into the Folder Options control panel for File Types and change the tif & tiff from QT picture viewer to windows picture and fax viewer.
So not sure why the QT control panel will not respond, there are other file types in the Folder options control panel on this computer other than tiff's that are still associated to QT, but didn't try changing them, perhaps that needs to be done?
Good post I didn't realize this before reading your post, if I come across anything further I'll post back.

Just upgraded to 4.3.3 on my iphone 3gs. Now none of my apps that are not Apple basic apps will open.

I just upgraded my 3gs to 4.3.3. When I try to open an app, it opens for a second or so, then closes. Two finger reboot didn't work. Regular iphone apps like Photos and Clock work fine. Tried turning off and on the location services as this patch was supposed to catch. What now, another patch to patch the patch! Ken

I just upgraded my iPhone 4 to OS5 and had the same issues.
All of the Apple applications / components worked. However, any non-apple application would flash open but wouldn't work and they were running in the background. After reading this thread (although it pertains to a different upgrade), thought I'd try it and it worked for me. I just went to iTunes App Store on my phone and downloaded a free app and presto!... now they all work again.
Thanks for the tip... and the time saved trying to troubleshoot.

Files and apps not opening by 2x click in Finder window?

Folks:
No situation on my older G4 iBook running 10.4.11: I can't get files or applications to open or launch from a finder window by clicking on them; they do open by highlighting and then command + o. And any apps I have in the Dock launch by single click. I t seemed to begin when I tried to "Save as" a Appleworks file into a .doc format which caused AW to crash--I did that several times. When I re-launched AW it said, "your settings have been changed, do you want to keep the new settings or the old?" I clicked on "new" . . . still couldn't get the AW file into a Word format so I went to PDF. Seems like after that the inability to open all files or launch apps from the Finder windows. Ran ONyx Maintenance . . . re-starte, didn't seem to help. Any ideas appreciated--is this a "known item"?
e.e.p.

Hi, long time no see!
First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
If that doesn't do it try this.
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions...
Reset Launch Services...

Reboot.

Reinstall OS X

Some apps are closing as soon as I open them.

A couple of my apps are closing when almost as soon as I open them. I tried holding both buttons until the apple logo appears but this did not resolve the issue. Also tried deleting and reinstalling but this did not seem to help either. Can anyone please help?

Have you synchronized to your computer lately? If you did, did you enable app synchronization too? That can be overlooked and cause this sort of conflict.

What are .mkv files?? What app to open them?
