Quicktime player won't open anything. Mac pro

My quicktime player won't play anything. Need suggestion on what to do.

Can you launch QT by itself, not clicking first on a file? If so, then use Open and navigate to your file. Do you have any other media players installed (Windows Media Player, Realplayer)? Maybe one of them is set as default. Also browse through the More Like This threads to the right to see what others have tried.

Font from G5 won't open on Mac Pro. I get a permission error but it's unlocked!

I just moved a font over from our old G5 for a project I'm working on in InDesign on our new Mac Pro and it won't install into Suitcase Fusion 4. So, I tried double clicking on the font to see if it would install into Font Book and I get this:
You do not have permission to open the document CREM1.TTF.
Contact your oputer or network administrator for assistance.
So, I check the properties on the font and "Everyone" was set to "None" for the Privilege. So, I changed that to Read & Write and I still get the same error when I try to double click on it. Over on the G5 I changed the Privilege there and sent back to the Mac Pro. Same thing.
I double click on the font on the G5 and it opens up Font Book like it should. So what the heck? Why can't I get access to this dang font on the Mac Pro? Any thoughts?
10.7.3

Thanks for the suggestions... tried changing resolution and that had no effect, and I've checked my Perian and DivX installations in System Preferences and both say they are completely up to date. I upgraded Quicktime today to 7.5 before all of this became a problem -- but I don't know how to upgrade iLife. In Software Update everything is completely up to date (eg each of the iLife apps).
Oh well, iMovie is not very useful to me anyway -- just somehow annoying that it fails to work. No point flogging a dead horse!!
Any other ideas gratefully received... many thanks in advance

Basic Apple applications won't open on Mac Pro after Mavericks upgrade

Hi,
I'm having issues opening a number of basic applications including Quicktime and Itunes
Through the App store I have updated everything, the last one I was holding out on was updating Itunes. I did that last night and now today Itunes won't open.
I click the image in the dock, the icon briefly bounces upward and then after bouncing down does not open or display any kind of error message.
I am running a 2008 Mac Pro w/ 2x2.8ghz quad-core, 10gb of RAM, these issues began after updating to Mavericks.
Many other apps including FCPX, Adobe Premiere CC, VLC, App Store, are all working fine.
It seems to be an issue with just basic Apple software - please help!

IWork 06 won't open on Mac Pro

New Mac Pro. iWorks 06 (Keynote 3.0.2 and Pages 2.0.2) won't open... "not supported on this architecture". Tried reloading iWorks twice from original disk. Says "successful". Isn't. Can't see or use my past presentations. Help!

I concur, I have the same error on a MBP running 10.5, just got it and used the Apple migration tool. The tool transferred the app, but it still won't work. Reinstalled, same thing like you received Roaster.
I think you, me, and one other person that posted this same message in December are the only people in the world with this problem, spooky... :<
If you find out anything, let me know, I'll do the same by posting here.

IMovie won't open on Mac Pro (Intel, 10.5.3) -- just hangs

I don't normally use iMovie but tried to open it today on my MacPro and strangely it just hangs while launching.
I reinstalled from the discs that came with the computer, but that made no difference. I deleted iPhoto and iMovie preference files, but that made no difference. I've even turned off Little Snitch as I saw on the web that there was a potential conflict there. I've run software upgrade and everything is apparently up to date (iMovie is version 7.1.1) I have also looked at the package contents for iMovie as suggested on another site, but everything seems to be there.
I have no idea why the application won't run. Does this sound familiar to anyone? Is there another conflict between iMovie and any other known applications?
Thanks

Quicktime player won't open

I am trying to open Quicktime, but I have the same problem as with 'Time Machine' - I click on both in the Applications window in Finder, & they do a little 'jump' & then sit there, doing nothing. Quicktime even appears in the dock, but I still cannot make it open by clicking on it.
Is there any other way of playing AVI videos? I have loads of these - NO problem playing them in Windows, but of course Apple has to make everything really difficult. The Quciktime website tells me these files are supported, but when I actually did manage to open it, it told me it could not play it. Then it shut down & I've not been able to open it since.
Is there actually a direct e-mail address where we can write to Apple support technicians? I have only had this Mac a few months but am posting almost daily on here because nothing seems to work properly, I'm getting sick of it.

Try an OS reinstall. Those should work w/o any issues.
Alternatively, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. Might also apply to new machines the first 90 days. BTW, the AppleCare Protection Plan's the best insurance policy available for desktop machines. Get it if you don't have it before contacting Apple.

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. Select Preferences/com.apple.quicktimeplayer.plist. Move the .plist to your desktop.
Open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
You might need to redo the View settings after an update.

I have quicktime player 10 installed on my mac and it is considered the (default) player. How can I get my Quicktime 7 Pro as my default player?

I have quicktime player 10 installed on my mac and it is considered the (default) player. How can I get my Quicktime 7 Pro as my default player? When I downloaded video from my phone, I couldn't hear the sound because Quicktime player 10 automatically opened the file and there was no sound, When I opened the file in quicktime 7 Pro, the audio was fine. I would prefer to have all movie files open automatically using my Pro version. Any suggestions? When I trashed the QT player 10 and clicked on the .3g2 movie file, it didn't automatically open with QT 7 Pro. Instead a window opened wanting to convert the file to Flash. I don't want that to happen.

Try This...
Highlight the file you want Quicktime 7 Pro to open -
Goto File > Get Info or (CMD I)
In the Get Info window, scroll down to "Open with:"
Select the player you want to open the music file.
Click the "Change All..." button if you want to
"Use this application to open all documents like this.”

My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start

My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start. I installed DiV X today and all this happened is there anyway to fix this?? I went through everything dragging the icon to the trash and deleting it from safari extentions.

Download and install
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs. In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them), particularly any DivX extension to Safari. However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/en/software/mac Note that Perian will be discontinued after the release of Mountain Lion: http://reviews.cnet.com/8301-13727_7-57434082-263/perian-plug-in-for-quicktime-t o-be-discontinued/?tag=txt;title

Quicktime player won't upgrade to Pro

I've properly entered registration code and the panel shows that I've been upgraded but none of the Pro features are active and it still shows that I'm only able to use QuickTime Player. I've restarted computer which is running OS X 10.4.11 and Pro still doesn't show.

no. the menu bar says QuickTime Player and the functions associated with Pro remain greyed out.

HT3523 hello, this is the error I get when I try to play a video QuickTime Player can't open "solea-antonio-walter.mov" because a required codec isn't available. Any idea what I need to do? thank you

Hello,
This is the error message I get when I try to watcha burnt dvd, can anyone tell me what I need to do?
thank you
QuickTime Player can't open "solea-antonio-walter.mov" because a required codec isn't available.

Quicktime X is a great little piece of software. However, Quicktime X is very finicky on which codec/file format it can decode/play.
Luckily, there are DOZENS of alternative video/media players and extensions available for the Mac. Some of them are even FREE. Some of the better FREE ones include...
PERIAN (quicktime extension)
http://www.macupdate.com/app/mac/22923/perian
QUICKTIME 7.6.6
http://support.apple.com/kb/DL923
VLC Media Player
http://www.macupdate.com/app/mac/5758/vlc-media-player
NICEPLAYER
http://www.macupdate.com/app/mac/15136/niceplayer
... And if none of those work, there is a possibility that, that video file may be corrupted.

Imovie won't open on mac

imovie won't open on mac
what do I do .... I have clicked force quit as it is unresponsive?
I have shut down computer. Unplugged power for 30 seconds and opened back up still the same problem. Help please!!!

So you don't have the iLife 09 disk either? (Can't remember if that was a separate disk or not).
Hmmm, it'd be better if you had the iLife disk.....
So, first you need to buy Snow Leopard (call Apple, it's the best price there); once you install it, update it to 10.6.8. That will give you the Mac App Store - you need that to buy Mountain Lion (download only, no disks). You will also want to up your RAM memory toa s much as you can - Mountain Lion is somewhat of a memory hog.
If you don't have your iLife disks, then a bootable clone on an external drive is an absolute must have just in case. You should do the first one before you install Snow Leopard just in case. Then, once you're up to 10.6.8 and all your applications are updated 9ncluding iLife, make a new bootable clone before you download/install Mountain Lion. Keep that clone safe just in case you need to revert or something goes wrong (especially if you don't have disks).
Once Mountain Lion is downloaded, first dismiss the installer and find it in your Applications folder. Make a copy of it and put it in a safe place (so you don't need to download it again). Then begin installing; when finished, run Software Update. Hopefully, your iMovie will be updated to the latest version. At that point, I'd make another clone and keep that one updated.
Having said all that, I'm not sure about iMovie not responding now - since you don't have disks, you can't reinstall it, so I don't know if upgrading will work. Normally one should take care of any problems before upgrading, but unless you want to buy a retail iLife 09 or 11 (which is still available online here and there), there isn't much you can do about installing.

Adobe Illustrator CS6 won't open in Mac 10.10 without Java SE 6 Runtime. Where do I get it.

Adobe Illustrator CS6 won't open in Mac 10.10 without Java SE 6 Runtime. Where do I get it.
I went to Jave and downloaded the latest version of Java 8 Update 31 for Mac, but it still won't open.

dchasin,
You may be able to get round the legacy JAVA requirement as follows:
Create empty folders at “/System/Library/Java/JavaVirtualMachines/1.6.0.jdk” and “/System/Library/Java/Support/Deploy.bundle”, to make Illustrator use Jave SE 8 as it should.

Others have found that it may depend on browser. Specifically, a switch from Safari has solved it in one case.
