Thanks

Hi,
If you have the suite then you have to download the whole suite otherwise the Serial Number will not work, if you only download Photoshop. Once you download the suite you can choose to only install Photoshop and use the Serial number you have.
You can download from here.

If you get the message:Setup" can't be opened because it is from an unidentified developer , You can follow Fix the “App can’t be opened because it is from an unidentified developer” Error in Mac OS X .
**You can change it to MAC App store and identified developers afterwards.

HT3775 BDMV" can't be opened because it is from an unidentified developer. How do I solve this?? Am I losing all the video files I have in my camcorder??? Please help me!!! Thanks

I am downloading the memory card from my camcorder into my MacBook Pro with Retina display. It usually popped to the file called AVCHD then CLIP to show all the videos. But not this time, it automatically changed to BDMV. I do not have idea how this happened while I left my notebook on and I was away for a couple of hours then back to the living room to work on each video as to type name of file etc.
Now, I cannot even open them into CLIP because I am still getting BDMV with a popped sign that said BDMV can't be opened because it is from an unidentified developer. (I do not even understand what this is supposed to mean??) also with the bottom message that stated "Quicktime Player created this file yesterday at 1:52pm" I am like uhhh how can QT player do this without my authorization??
Please help me how to solve these and get all of my videos back that I saved in my camcorder. Let you know that I tried to insert the memory card back into my camcorder and all these videos are gone. Now I am having a HUGE headache because of this!!
What should I do now???

HI,
Did you ever figure out how to get them back? The same thing happened to me yesterday. I was able to open the file in VLC media player (you can download this app), but the file had been corrupted. It was only the last clip I had recorded, all the others were lost. Even the clip that will play is messed up

HT201364 texmate and git 1.8.4.2 won't work on OS X Mavericks. I've downloaded them repeatedly and the following errors display "Textmate is damaged and can't be opened" and Git states "can't be opened because it's from an unidentified developer". Please

MedlockDustin,
for TextMate, you’ll need to download TextMate 2.0 alpha, since earlier versions of TextMate aren’t supported on Mavericks. The file will be named “nightly”; save it to your desktop. Once the “nightly” file has finished downloading, rename it to “TextMate.app.tar.bz2” — that will give it the “BZ” icon on your desktop. Once it’s been renamed, you can double-click on it, and TextMate.app will appear on your desktop. Use your administrative login to move TextMate.app to your Applications folder.
Regarding the “unidentified developer” message displayed by trying to open git 1.8.4.2, please refer to this Apple page for the workaround.

Trying to download software driver for Novatel u727 mobile broadband card. Keeps saying that it can't be opened because it is from and unidentified developer and my security preferences only allow installation from the Mac App Store .. any suggestions?

Would it help to spend $20 and download the OS X Mountain Lion .. the link send directly from Novatel had Snow Leopard in it .. I haven't owned this laptop for long and have no clue what Mountain Lion or Snow Leopard is
Any help and suggestions would be appreciated

Snow Leopard (10.6) an Lion (10.7) are names for two versions of Apple Operating Systems. Change your System Preferences>Security & Privacy to 'Anywhere' and you should be able to install the driver.
Ciao.

I just figured out a solution. I connected my ipod to my computer, went to the 'info' tab on the menu for my ipod. I checked 'Sync Mail Accounts', which were greyed out until I selected them. That connected me to the Cloud and everything went back to normal. Hope this helps someone else!

My hard disc crashed and I have no back up other than the music I have on my ipod. I have downloaded Itunes onto my new hard disc but I have read if I just connect my ipod it will wipe everything on the latter rather than upload from it ?

Welcome to the Apple Support Communities
You have to transfer the music from your iPod to iTunes. There are some third-party applications that can do it > https://discussions.apple.com/message/11319208#11319208

How do I load on Office:Mac onto my new MacBook Pro when it doesn't have a disk drive?

How do I load on Office: Mac onto my new MacBook Pro when it doesn't have a disk drive - I don't want to have to purchase another copy.

Glad you were able to solve your problem. For the benefit of others who may find this discussion later, allow me to suggest another possibility.
If you have access to another Mac running Lion or Mountain Lion with an optical drive, you should be able to use the Remote Disc feature to access the optical drive on that other Mac.

I have copied my iTunes library onto a new computer, but when I play back the songs there seems to be random "miss" or "drop out". No probs with old computer, just the new one. I'm onto my third new computer - same problem. Any suggestions please?

I have copied my iTunes library onto a new computer, but when I play back the songs using the new computer, there seems to be random "miss" or "drop out" during play back, similar to a small scratch on a vinyl record. Although when I play the same song over again, the "miss" occurs in a different location during the song. No probs with old computer, just the new one. I'm onto my third new computer - same problem. Any suggestions please?

You don't say which version of iTunes you are using, but the symptoms you describe have been encountered by some users with the 64-bit version of iTunes 12.1.
There is an alternative version for 64-bit editions of Windows here:
iTunes 12.1 for Windows (64-bit — for older video cards)
that seems to address the most of the playback issues that some users have been reporting with the full 64-bit version of 12.1.0.77 - including problems with Bluetooth speakers where either sound is degraded or completely absent. The alternative installer here is the same architecture as most previous "64-bit" versions of iTunes, i.e., a 32-bit application with a 64-bit installer. The "for older video cards" label appears to be something of a misnomer as some people have reported that this corrects problems found on current / high-spec systems.
Some users have reported that after installing this alternative version it is necessary to adjust the "Play audio using" selection (normally to "Direct Sound" rather than "Windows Audio Session", though this may vary based on your audio hardware/drivers) in Edit > Preferences > Playback to restore glitch-free audio (one part of the reported symptoms is that the "Direct Sound" choice isn't available, usually in Windows 8). It may also be necessary to ensure that your Bluetooth speakers are active and selected as the default audio device before you run iTunes.
If this doesn't address the issue, you may want to think about reverting to iTunes 12.0 - see Turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for steps needed to completely remove all installed iTunes components, and for links to the 12.0 installers.

I have lightroom 5 on my desktop, I have downloaded it on my new laptop, but I do no have the registration code from my update. My last one is from lightroom4, how do i get the registration code?

I own lightroom 5 on my desktop, I have downloaded it on my new laptop, but I do not have the registration code from my update. The code is from lightroom4. How do it get the number so I can register it on my laptop?

If you own Lightroom 5, you received a serial number for it, that is what you want to use.
If you don't have it any more (not a good idea, by the way), you should be able to find it via: Find your serial number quickly

You need to read and follow the Boot Camp instructions. Boot Camp Assistant is already on your computer in the utilities forderf. You run Boot Camp Assistant. Part of the process is to to then download the Windows Support software. This download is then installed from within Windows.
There is no Boot Camp download that needs to be installed or unzipped from within OSx which you seem to be doing.
