MPG file won't open on Mac

I have a large mpg file (400 mb) that runs fine on my PC laptop but I get the error:
QuickTime cannot open the file: "neurotoxicology.mpg"
it is not a file that QuickTime understands (-2048)
on my Mac.
I upgraded to QuickTime Pro, with no improvement. Is there a codec I can download to fix this, and if so, how would it be installed?
Is there a better player our there for mpg files?

there is a programm out there called "mpeg streamclip". do a google search for it.
its free and it will play mpgs. it will also allow you to convert them to just about anything. imovie native format is DV25. convert to DV and select that option. it even breaks it up into the size files that imovie likes. (about 9min chunks).
cheers,
matt

Pdf files won't open on Mac

I have a Mac, OS X, 10.9.4. I recently downloaded the newest version of Adobe Reader 11.0.09 and installed it. I left my computer before the installation was completed, and it turns out it wanted me to close Firefox. I did, but it was the next day. The installation finished, but maybe a little weirdly -- I don't remember. Now, certain .pdf files (that I have opened many times in the past) won't open. The adobe page opens, with the filename at the top, and the page blank below, then the page disappears after a couple of seconds. Some .pdf files open fine. All files will open with Preview. I think I need to reinstall Adobe Reader, but don't know how. If I try to download and install, it says my version is up-to-date. Please help.

Office for Windows files won't open on mac

Why won't Word documents and Excel files created on a Windows machine open on my new MacBook Air? I never had this problem on my old MacBook Air. I'm running Mavericks and all software up to date.

I am running Office 365 and yes it all works fine other than this specific problem. I have a machine that was used by another employee for 6 months. It was wiped clean and set back to factory conditions according to the IT group and then set up for me. I transferred all my files from my old Mac Air to this one through an external hard drive. Those open fine. All files have extenders based on the vintage; doc and docx, xls and xlsx. Denise has a company Dell and a personal iMAC. Denise can open the files on either machine at home. She copied all files to a flash drive (from the Dell) and I loaded them onto my Mac. I was able to open one of the docx files in text edit and then close (not save) it. It will now open in Word. But this didn't work on any of the others.

After Effects Windows 64 bit file won't open on Mac!

I have CC on a Windows 7 (64 bit) system and on a MAC OSX Snow Leopard, 2.66 Ghz Intel Core 2 Duo Version 10.6.8 and when attempting to open a Windows created After Effects file on the MAC got the "Can't open 64 bit version 12.2 file on this Mac" message. What to I have to do to make them compatible? I wasn't told this when I signed up!

Your answer is either to upgrade your Mac's OS or to save the CC file as a CS6 file. (Which is possible according to this list.)

RDP file won't open on Mac with double click

Hi
We have sort of created our own RDP Gateway and this used to work fine on Mac's double click the RDP file and this automatically opened Microsoft Desktop App and you could login in once entering username and password. Since the last couple of updates to
RDP App it doesn't work when double clicking the RDP downloaded file, it works if I import it into the RDP App and start it but not when I double click it.
This is obviously causing an issue with quite a few users and causing our number of support calls to increase dramatically.

I just used stellar phoenix mac data recovery and it seemed to work but now my files won't open. Even though they are "jpeg, mov" files the error message is could not be opened. The movie's file format isn't recognized. " Any help or are they corrupted

I just used stellar phoenix mac data recovery and it seemed to work but now my files won't open. Even though they are "jpeg, mov" files, the error message is "could not be opened". The movie's file format isn't recognized. " Any help or are they corrupted?

Sounds to me like the file is probably corrupt. If you had hard drive corruption or damage, that could easily result in recovered files not being fully intact. If you were trying to recover accidentally deleted files, it's possible they might have been partially overwritten before recovering. There are never any guarantees with file recovery.
Without more information on the circumstances that led you to try recovery, it's hard to give advice on what to try from here. You could always try another file recovery tool, like Data Rescue 3. Just be sure you're taking appropriate precautions when doing recovery. See Recovering deleted files.

Pdf files won't open in Safari running on a Mac

I just upgraded my MacBook Pro to Snow Leopard in preparation for Lion and ever since the upgrade, pdf files won't open in Safari. I have Reader 9.4.5. It opens documents that are on my machine, it just won't open in Safari, nor do the documents download.

MIght be helpful to disable Adobe plugin by going to Adobe Reader's Preferences -> Internet and unchecking "Display PDF in browser using".
Then dump the atrocious bloated Reader.

HELP! Files won't open and previously had Firefox icon instead of DW icons! Leap Year thing?

Hi! I went to update my website, which I do every night before the first day of every month and all the files had a FIrefox icon instead of the usual Dreamweaver one. I have shut down, reinstalled DW MX 2004 but the files still do not open. The icons have now changed to DW but they are not opening with right click, opening from Applications folder, double clicking the file, from get info and open with DW. I am stumped. HELP! Need to update for March 1st.
Is it something to do with Leap Year 29th Feb? Checked the clock in preferences but can't see how this affects it.
Firefox is always updated but the latest version does not seem to be as efficient as previous upgrades. We installed Chrome as well. Do they interfere with each other?

Hi Ken
I wish the 7.1 updater download had helped but it didn¹t. All the files
were backed up before the installation, which went fine.
Mac 10.5.8
We used Disc Warrior to defrag the hard drive, which did not make a
difference.
We recently started using Chrome, so now have 3 browsers in the dock,
Safari, Firefox and Chrome. Do they interfere in any way with each other?
The files, which I hadn¹t touched for a month as I update on a monthly
basis, initially had the Firefox icon.

HI,
If iChat is Open and your think Accounts/Screen Names are logged in then go to the Window Menu
This should list the accounts that are logged in with various keystrokes ( Apple/CMD ( or ⌘) and a Number) shown next to them.
Using these should get the Buddy list "back".
It is possible to Hide the Buddy list and then Quit iChat.
iChat will then "remember" where the windows were eve if this was Hidden.
Can you confirm that after reinstalling or restoring from Time Machine with possibly an Earlier Version you have Downloaded the COMBO version of OS X 10.6.8 and "run the COMBO" (Installed it - again) to update iChat ?
It is possible the text chat Window is also Hidden on double clicking a Buddy.
The easiest way for this to happen is to use a second Display and drag some windows to the second Display.
iChat "remembers" where you last had Outgoing Chats so Audio and Video windows will be where you left them as will Text Chats.
Incoming Chat Invites are normally in set places unless there is a chat already open to that Buddy.
With Windowing issue like this is sometimes pays to delete com.apple.ichat.plist itself (on it's own) and restart iChat (this plist holds the window positions amongst other things)

FCP 5.1 file won't open in FCP 7

Hi.
I am at my wits end...I have a FCP 5.1 file that I have been working on for years.
I had to upgrade to FCP 7 for reasons I won't go into and now my FCP 5.1 file won't open.
It is a file with footage from P2 cards. It has magic bullet/looks builder used throughout. I am not sure if that is the issue at one point ONE of the messages I got when it crashed (I got a few different ones at different times) was something about looksbuilder not working right.
In a nutshell, it slowly starts to open and then quits. (It gets to about 33 percent open over the course of 45 minutes and then crashes.)
The file is about half a gig and there is plenty of room on the MAC itself so it shouldn't be that the Mac is overtaxed.
I don't know what to do.
I tried opening various back-up copies, etc. because I thought maybe something was just corrupted. NONE of them open.
I tried deleting render files to limit how much it was trying to process when it opened the thing.
I even tried turning off the external drives that hold the media hoping that if it couldn't find the media it would just open the shell of a file for me and maybe I could reconnect it all later. Obviously, grasping at straws...
I am out of options. Do I just need to wipe my computer and reinstall 5.1 from scratch? That would stink because there is another project being worked on on the computer that is a FCP 7 file.
I tried putting a copy of FCP 5.1 back on the computer (so I have 7 and 5.1 on there now) to get it to open, but FCP 5.1 won't work either now (I get General Error 41 - whatever that means) Maybe you can't have two versions of FCP on the computer? Maybe it thinks it got opened in 7 so now it won't work in 5? even though it never fully opened? Guessing...
I'd appreciate any and all help. All I want to do is open the 5.1 file and save it in FCP 7 and work from there.
Thanks!
Shari

Hey Michael:
Thanks for the response. I did something similar in that I opened the file on another computer that had FCP 7 and it was fine. So I saved that. Then I went to my Mac and tried to open that file and it crashed...but it said something about Looksbuilder...so I contacted them and they had me uninstall, reinstall and then fix the preference files for Looksbuilder and it now opens.
YAY!
Thanks again,
Shari

Old Applications & files won't open in OSX-Tiger/Classic

[post moved from other forum]
I finished my Powerbook's hardware upgrade with success yesterday(with thanks to JPL, Sig, A_Brody and other's great advice). System is now Powerbook G3 400 Firewire with 512mbRam, new 40GB HDD, and OS-X Tiger. However...
I can't seem to get the older Applications or their files to open. I get the error message:
"There is no default application specified to open the document Appleworks 6"
and/or
"Could not be opened because the application that created it could not be found--- could not find a translation extension with appropriate translators"
The upgrade/update procedure included...
===Back-up all files on the old 10GB HDD to an external USB drive.
===Remove old and replace w/new 40GB HDD, also install new 512MB PC-133 RAM module in lower slot.
===booted from old OS CD and ran Hard drive set-up utility with two partitions, one 30GB the other 10GB.
===Install OS 9.0.4 from that original Apple software CD onto the first 30GB partition.
===Onto same partition, ran OS-9 Update 9.1.0, then 9.2.1, then fireware update 4.1.8f5, then Update 9.2.1
===Installed OS-X Tiger onto the first 30GB partition
===Moved all backed-up files from the external USB drive onto the second 10GB partition.
I have tried running the old applications in both OS-X Classic mode and also after changing the "Start-up Disk" to the smaller partition (which should be a clone of how the original Hard drive was set-up i.e. folder structure etc.)
I'm quite surprised that when re-booting to the smaller partiton, that although it looks just like my system prior to upgrading, the apps don't run and the files don't open those older apps that created them. I assumed that the smaller Partition--and booting to it--would be the same as if the original Hard drive was still in the powerbook.
When I get those error messages above, I have followed the "Choose Application" button thru to where I could choose the application. I follow to the "Applications (Mac OS 9" folder to where the actual APPLEWORKS 6 app (for exmaple) is located, but it is greyed out and can't be selected. BTW later I did copy all of the contents of the original "Applications" folder from the backed-up HDD into the OSX "Applications Mac OS 9" folder. Also note, the apps in that folder are listed as KIND "Unix Executable File". The files (in this case AppleWorks files) are also listed as that file KIND.
===In the OSX's System Preferences/System/Classic/Advanced tab, I have tried the REBUILD DESKTOP procedure--with no effected change. I know I read elsewhere in discussions that there was a procedure to re-boot with a certain keyboard held-key combo that allows to re-build desktop upon booting?? I don't remember the keyboard combo. And,not certain how that procedure is different.
===In the change Start-Up disc Utility, I now see four Systems to choose from...
Mac OSX 10.4 on New 30GB HD
Mac OS 9.2.2 on New 30GB HD
Mac OS on Old 10GB HD (that's the smaller partition),
Mac OS 9.2.2 on New 30GB HD
Network Start-up
Both the second and forth choice will boot-up to OS 9.2, but as mentioned the apps won't run and files won't open
I'm guessing the reason the third choice won't boot (it reverts back to OSX Tiger when I try) is because that original System copy is OS 9.0.4 (backed-up prior to running the OS-9.1 and 9.2.1, 9.2.2 updates.). Also note, when in OS 9.2.2 when I go into that Utility... Apple/Control Panels/Startup Disk it doesn't list the old OS on the smaller partition. BTW could I now run/perform the OS-9 updates to bring that System on the smaller HD partition up to OS-9.2.2 with out causing problems (and maybe providing solutions?)
I wonder...
??? Why would I be having to choose which application would open an application---wouldn't an app open on its own (Unix Executable File")
??? When I moved the orig HD back-ups on the external USB drive I noticed a file with some kind of PC icon was being created within the folder. Currently I see that the file is now displayed as FINDER.DAT. Does this file relate to the error that refers to "appropriate translators"? Could the Apple Macintosh files being backed-up onto an external USB drive that may not have been formated as Apple HFS type be causing a problem?
??? Why wouldn't the smaller 10GB partition with the old HDD back-up copy moved to it not function like the original Hard drive? Particularly when I choose to boot to its SYSTEM w/Start-up Disc? BTW when I choose that route, the powerbook just boots to OSX Tiger.
THANKS for any replies, you all have been a great help with the challenges of upgrading...
MSG-PWRBkG3
PS:
Sorry for the long post. But, I have included as much up-front details as possible to assist in your replies. I also want to help others reading this thread later on as to what (correct or incorrect) procedures were followed... to help them see how these in-compatibility scenerios would be similiar to their situations... leading to solutions for all.

Thank you for including as much detail as you did. It makes it much easier to troubleshoot this type of issue. What I'll do is basically follow along with the procedure you used and point out where you (unknowingly) ran into problems.
"Back-up all files on the old 10GB HDD to an external USB drive."
Okay, I'm betting that this external USB drive was formatted as PC-Exchange/Windows format. Since this type of disk format doesn't have native support for the special "Mac" information about files (such as resource forks and HFS metadata like file type and creator codes), when Mac OS writes files to these disks, it needs to use a special method. When you copy the files from OS 9, OS 9 adds special "FINDER.DAT" files and also stores the resource-fork-parts of the original files inside a "RESOURCE.FRK" folder on the disk. My FAQ goes into more detail about this. When, from OS 9, you look at the files you just copied to the PC-formatted disk, and they appear identical to the files on your original 10 GB hard drive, that is in fact a complete illusion. The files as they exist on the PC-formatted disk are very different from what they appear. When you hook it up to your OS 9 Mac, the files appear fine, and you can copy them and have them work just like the original files did. If, on the other hand, you hook this PC-formatted hard drive up to your OS X Mac, it looks at the files in a completely different way. If you copy the files off of this disk from OS X, most of the files won't be usable.
"Remove old and replace w/new 40GB HDD, also install new 512MB PC-133 RAM module in lower slot."
"booted from old OS CD and ran Hard drive set-up utility with two partitions, one 30GB the other 10GB."
"Install OS 9.0.4 from that original Apple software CD onto the first 30GB partition."
"Onto same partition, ran OS-9 Update 9.1.0, then 9.2.1, then fireware update 4.1.8f5, then Update 9.2.1"
"Installed OS-X Tiger onto the first 30GB partition"
"Moved all backed-up files from the external USB drive onto the second 10GB partition."
If you did this from OS X, you will run into problems, whereas if you do this from OS 9, you'll be okay. The reason for this, as I mentioned above, is that OS X doesn't know how to "see" the files in the same way that OS 9 does.
This is what I would do. Make sure you still have the PC-formatted drive with the files you backed up from OS 9. Reboot into one of your versions of OS 9 that works properly. Hook up the external USB drive, and the files on it should appear properly and function properly. Now copy the files over onto your local hard drive and they should work properly as well. The files that you copied over from OS X won't be useful and can be deleted. Then reboot into OS X and you should be all set.
Hope this helps....

Pages file won't open

One of my pages files won't open. It has been fine, but all of a sudden a message comes up saying the file cannot be opened. There is no information as to whether it has been corrupted or not. When I try to open it in the mac-Microsoft office program it says the file is too large.
Either it is just too large at 669MB and I need to reduce the size? or perhaps it is corrupted. I can open a preview version from its folder, by going to file and 'Quick Look "file name." But I can't copy any of it from there to paste into a new file...
Could someone tell me how to reduce the file size? Or increase the memory of the Pages application? Or some other way of opening it.
And no, I haven't backed it up like a fool.
Thanks guys

Yvan,
Thanks for the tip on Activity Monitor, I did not know about that! I have a similar problem, and I hope you can help me. I have a MacBook with 2GB mem and early Intel Chip (see SN provided).
I am writing a book with MANY pictures. They are all .JPGs and are fairly big. I have to keep the book in a single file if I want the Table of Contents (TOC) to work (I think... TOC is quirky). The file is 165.4 MB on disk and loads in Activity Monitor as 173.5 MB. With Preview Open and Safari Open, the system memory report says Free 161MB, Wired 296 MB, Active 1.06GB, Inactive 497.4 MB, Used 1.84 GB, Swap used, 41.8 MB. Pages loads the book slowly and functions okay with major hesitations from time to time; but it does take a VERY long time to save and will freeze with a wheel of death from time to time.
The obvious answer is to divide the book; but that would defeat the TOC advantage I'm enjoying.
Advice?
