Why won't powerpoint files open on my MacBook Pro?

Could someone let me know why some files, such as PowerPoint, which worked find before, are no longer opening on my MacBookPro?

Office 2004 does not work in Mavericks. Neither will other older applications:

Why won't .mp4 file open in QT 10.0 (or iMovie'09) and OS 10.6.8?

I'm trying to edit some .mp4 movie files, but I can't open them in Quicktime (10.0 or 7.6.6), or iMovie '09 (8.0.6) or Final Cut Express (4.0.1). I've got a MacBook Pro running OS X 10.6.8 (Snow Leopard). When I try to open the file in QT 10, it says "The document “name.mp4” could not be opened"; whereas in QT 7 it says "The file could not be opened. An invalid sample description was found in the movie." In iMovie, the file is greyed out when I try to import it.
The file will open and play fine in VLC, but I can't do the editing I want there. The Media Information pane in VLC says: the codec is "H264 - MPEG-4 AVC (part 10)(avc1)", it is HD resolution (1920 x 1080), it has a frame rate of 59.940060, and the Decoded format is "Planar 4:2:0 YUV". It also has an audio track (MPEG audio) and a subtitle track. I also tried opening these .mp4 files on two Mac laptops that a friend of mine has. Interestingly, they would not open on one (I think running Lion with QT 10.0), but they DID open on the other newer laptop (running Mountain Lion with QT 10.2).
I first assumed it was just a case of not having the right codec. So I tried copying all the codecs from the Mac laptop that *could* open them, but that didn't work. Then I searched for and downloaded codecs that I might be missing, such as "avc1Decoder.dmg" from MyCometG3 and http://www.macupdate.com/app/mac/23875/avc1decoder, and x264Encoder 1.2.27 also from MyCometG3, and I put them in my Library/Quicktime folder and restarted Quicktime, but neither solved the problem. I also tried opening the .mp4 files in MPEG Streamclip (1.9.2), but it says "File open error: unrecognized file type". When I tell it to "open anyway" it tries and then says "File open error: can't find video or audio tracks".
I tried opening one of these .mp4 files in Handbrake (0.9.8) and it was able to open and convert the file to an .mp4 that is then openable in QT 10 with a format of H.264, AAC, and a reduced frame rate of 29.84. However, this doesn't seem like a good solution because it takes about 2 hours to convert a file with 30 minutes of video. I just want to be able to trim these big files down to some short video clips that are in an accessible format.
Any help would be MUCH appreciated. Am I missing the right codec? Or, as I'm beginning to wonder, is this format one that is too demanding for OS 10.6.8 and QT 10 and they just cannot handle it no matter what codecs I have on my computer (because of the 60 fps frame rate? Or is it the subtitle track?). Or is the solution to upgrade my operating system to Mountain Lion (10.8) and QT 10.2? My 15" MacBook Pro is about 2 years old with a 2.66 GHz Intel Core i7 and 4 GB of RAM (1067 MHz DDR3). Thanks.

Wow! A lot of ifs, ands, and maybes here.

An invalid sample description was found in the movie." In iMovie, the file is greyed out when I try to import it.
To start off with, these messages and/or inability to opent/import files could stem from either security updates that see something in the file that it interprets as a possible breach of file integrity or the inclusion of data not expected in the associated file type while missing codecs are either identified and load but do not display or refuse to load but issue a message to that effect and possibly asking if you want to visit a web page containing codes you may want to add.

In the future, could you be more specific when describing the file contents. For the moment, I will assume the video is H.264 (MPEG-4/AVC) and the audio is AAC (MPEG-4) audio and not MPEG-1 layered audio. (I.e., while the former is to be expected with the MP4 file extension, some apps can "stuff" incompatible data into an MP4 container or users can manually change the file extemsion.) It also important to know if the "subtitle" track is embedded within the file or is contained in a separate file. (I.e., a screen capture of the media "info", "inspector", or "properties" window is usually the least ambiguous way to track content information.) It would also be nice to know if the VLC frame rate is for progressive or interlaced video if possible.
Basically, some apps are very touchy about file extensions and track content. iMovie '08, for instance, will not open a file containing extraneous tracks like 'tween, text, chapter, etc. embedded within the file. I assume this may also be true for "subtitle" tracks as far as your Snow Leopard players are concerned. In any case, if your version of the QT 7 player is keyed for "pro" use, I would perform a simple test here by deleting the "subtitle" track, saving the file, and then re-trying to load, open, play, and/or import the file in the various applications currently giving you problems. If this fixes the problem, then you will know the source and solution of your problem

When I tell it to "open anyway" it tries and then says "File open error: can't find video or audio tracks".
The indiscriminant installation of additional codecs often creates more problems than it solves owing to the logrithmic increased potential for the introduction of QT codec component conflicts. The normal "rule of thumb" here is to identify a missing codec and to then install only that specific codec component. Even then, there is a possibility that there may be a conflict but at least it is more easily identified so you can better evaluate which of the conflicting codecs to leave installed and which to swap only when needed/required. As to the use of MPEG Streamclip, it basically uses your system's QT component configuration of access of most codecs as opposed to VLC and HandBrake which contain their own, built-in codec support. So if QT is having a problem, it is often likely that MPEG Streamclip will also have problems.
I tried opening one of these .mp4 files in Handbrake (0.9.8) and it was able to open and convert the file to an .mp4 that is then openable in QT 10 with a format of H.264, AAC, and a reduced frame rate of 29.84. However, this doesn't seem like a good solution because it takes about 2 hours to convert a file with 30 minutes of video. I just want to be able to trim these big files down to some short video clips that are in an accessible format.
The HandBrake workflow forces a recompressing of the file data which is why it takse so long. That is why I suggested you try deleting any extraneous data tracks found in the source MP4 file container using QT 7 Pro and then use the "Save" or "Save As..." option to re-write the original audio and video data to a new MOV file container which takes much less time.
Am I missing the right codec? Or, as I'm beginning to wonder, is this format one that is too demanding for OS 10.6.8 and QT 10 and they just cannot handle it no matter what codecs I have on my computer (because of the 60 fps frame rate?

Probably not. The VLC reported data rate may either indicate the MP4 content is AVCHD/BD sourced or it is reading interlaced content as progressive which I have noted it can do on occasion when I compare the media info as read by various different apps and/or utilities. Since you indicate the file opens in Mountain Lion, my guess would be that your MP4 content is actually AVCHD/BD sourced since such support was only recently added to Mac OS X v10.8 software. As to moving up to Mountain Lion, as always, that is something you would have to evaluate for yourself. For instance, do you require PNG compression for video content? By default you would lose it under Mountain Lion and have to re-enable it manually if needed. Are there other pros and cons that you need to consider before upgrading to Mountain Lion? These are the types of questions and compatibility issues that only you can answer for yourself.

Why won't my music sync from my Macbook Pro to my iPhone 5?

When syncing my phone, the music doesn't go from the computer to the phone. Just recently I got a bunch of physical albums and after I uploaded them to the computer, I wanted to put them on my phone. I checked to make sure I have enough data, and I did. But when I try to sync the music from my Macbook Pro to my Iphone 5, it doesn't work. On my computer it says that the music is on my phone, yet it isn't. I tried deleting all the music and resyncing it, but that didn't work either. It shows some of the songs greyed out on the computer with dotted circles next the them, what is that? Also, on my phone, some of the songs have circles next to them with squares in them and when i click them they just turn grey. I've been trying for a few days and I am getting very frustrated. Please help!

I have this same problem. It is constantly recurring and after trying just about everything, I'm almost ready to give up.
Things I've tried, that have not worked:
restarting computer
closing all open apps on iPhone before sync
restarting iphone before sync
syncing with wire
syncing without wire (over wifi)
converting the music files to another encoding
dragging the music files individually onto the iphone in iTunes
dragging a selection of music files
putting music files in a playlist and adding that playlist
Does anyone have a solution?

Why won't PDF files open anymore?

Suddenly my iMac won't open most .PDF files - specifically those that are imbedded in the body of emails or may be identified by a hotlink on websites. But if one is simply attached to an email, that seems to open!?! The only thing I think I've done since everything worked properly was to agree to install Adobe Reader 10.1.3 and Adobe Flash Player. Can anyone help me to rectify whatever error I'm experiencing so that I can open .PDF files once again? Thanks, in advance, for your help!

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Why won't pdf files open from flash drive?

Some files I have on a flash drive will not open. Some error messages say file is damaged and cannot be repaired or cannot read (109) or internal error.

Damn. What about files that say "internal error"? Those files I have can open up, but some of the pictures and pages and text is missing on those files.

Why won't my files open? My recent ones will, but only those

My old garage band files wont open on garage band. When I open the application, I can open the most recently used projects, but the old ones are unclickable when i try to open them.

When I open the application, I can open the most recently used projects, but the old ones are unclickable when i try to open them.
Can you explain what you mean by 'unclickable'?
When you open the GarageBand, you will see only the most recent projects. Have you tried to double click your old projects in a finder window and they do not open? Is that what you are saying? Are there any error messages?
Were your older projects created with a previous version of GarageBand?

Why won't renamed files open in Bridge?

Hi
I renamed a couple of folders and when I tried to open the folders from the folders panel in Bridge a dialog said they were missing or had been moved.After dragging the folders to the desktop, creating a new folder in Bridge and then dragging the contents back from the desktop, Bridge opened them with no problem. Does anyone have a clue how I can rename a folder without this problem?
Thank you

Well you did change the name, How is Bridge going to know?
What I would do is just drag the newly named folder back onto Bridge.

Why won't my Iphone connect to my Macbook Pro?!

The thing is, I have transfered music for many time over the past year. My Iphone connected to my Macbook and everything, it loaded up iPhoto, iTunes etc. But now when I tried to connect my Iphone to transfer some new music it wouldn't even connect?!?! First I thought that it was the cable, but it wasn't because I can load my phone normally otherwise. Then I checked my USB-ports, but they worked just fine! After that I started to search everywhere for the same problem but all I could find was ''My iphone won't connect to iTunes'' and that was not the problem I had... I restarted both my devices and updated my iTunes on the computer, still nothing works... And now I'm sitting here looking for an solution I probably won't find... So please help me with this problem, I am getting really close to just throw the computer in the wall or something!

It is not uncommon.. !!
Go back in and setup wireless again.. let me strongly recommend you use a real utility.. not that toy in ML. See below.
Change the wireless name/s to SMB standard .. short, no spaces. pure alphanumeric. I recommend fixing the 5ghz to a different name at least whilst you have issues.
Now lock the wireless channels for 2.4ghz.. try 1, 6, 11 in turn. Keep whichever gives the best speed and range in your environment.
On the screen shots above I still haven't finished the setup.. wireless security should be set to WPA2 Personal.. and use a pure alphanumeric key.. mix of upper and lower case and numerals.. 8-12 characters is plenty for most.. if you are paranoid add a few more.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
For screen shots see this post.

Why won't Mountain Lion install on my MacBook Pro?

Ok, so I've just bought Mountain Lion from the app store for my 2010 13 inch MacBook Pro, it's been downloaded, and now I'm trying to install it.
It takes me to the first page, I accept the software license agreement and all that, choose that I want it to be installed on Macintosh HD, press 'Install' and enter my password... then nothing happens.
It accepts my password, so I know that's not incorrect, but just doesn't do anything. All I can do is keep pressing install and keep entering in my password, but it doesn't take me to a new page or start installing the software.
Ive tried restarting, that doesn't work. Please tell me I haven't just wasted £13.99!?!?
Thanks!

ive just obtained a password by email, entered it when asked, but then nothing happened No download started at all, not in dowloads and cant fnd what to do.
Went to app store and I can purchase it apparently for £13.99 but ive a free upgrade with this new retina macbook pro.
Any advice would be most appreciated please
thanks

Why won't Maverick install on my 2012 Macbook Pro Retina?

I can't sign onto the Apple Store, when I click install app it does nothing, what's going on? Running OS 10.8.5, plenty of disk space remaining.
This isn't the first time this has happened.

I'm afraid that didn't solve my issue.
I've shut down and restarted my MacBook Pro many times attempting to resolve this.
To reiterate, I can't sign onto my account at the Mac Store on this machine, it simply does nothing when I click on "sign in", therefore I can't do anything at all at the store as far as buying an app.
When I click on the Maverick Free Upgrade button, it turns green. Then I click on the green button, within less than a second, it turns from green "install" back to the "Free Upgrade" gray button.
I've used Macs since 1984, yes really, and never been as frustrated as this since the OS 7.0 debacle over a decade ago.

Are you trying to transfer the GarageBand projects or the rendered audio files? What version of GarageBand do you have on your iPhone?
I do not think you can share your GarageBand projects from your iPhone to GarageBand on your Mac, unless you have iCloud, afaik, only the audio files.
How did you transfer the song?
To share from an IOS device the Projects or audio files, see: Share GarageBand songs
