Every .dmg file I download is "damaged"

I've tried to install the newest java update, Pro Tools 10.3.4, Norton Antivirus for Mac, and a few others, and I have the same problem with all disk images downloaded from the internet. When I double click on the dmg file, it opens it, and I can see the contents. When I click on the installer files, I get an error message that says that the disk image is damaged and I need to eject it. Old disk images that I open work fine, but the fresh downloads are all giving me this error.

If right clicking the installer does not bring up a sub menu allowing you to select open, check your Gatekeeper settings. You may need to change them.
Side note: There are no viruses for OSX. No need for virus software. Especially, any from Nortons. You should trash it and get your $$$ back if you paid for it.

The dmg files have downloaded to the wrong folder - not finished with the install process

The dmg files have downloaded to the wrong folder - I am at the part of the download/install process where the "Welcome" screen appears asking for me to agree to the license agreement. Somewhere on your site, I read that they should NOT go to the applications folder but to the "Users" folder. Can/should I move/drag the folder with the dmg files into the "Users" folder"? If so, before or after I complete the install? I am running MAC OSX 10.7.4 on a MAC Mini.
Also, when the trial period is over, I will use the license number for the purchased software disks, should the dmg's/folders then be moved to the application folder or stay in the "users" section? I have Purvhased Adobe Photoshop Elements 10 and Adobe Premiere Elements 10, but somewhere on your site it was suggested to download them instead and use the license code at the appropiate time. If someone can help with these questions, I would appreciate it. Thank you

Hi,
In the Welcome screen, you can accept the license agreement and can go ahead with the installation. You will be asked for the serial number. If you don't have one, install it as a trial application. By default, it's installed in the Applications folder. However, you can change the installation folder in the third screen, if you have a reason. Please see the screenshot below:
After installing, you can't move application to a different directory by dragging. You need to uninstall and install it again in the folder of your choice.
Thanks,
Sunil

My Safari can´t open .dmg files after downloading

I updated to Mac OS X 4.9. But since this update, Safari cannot open .dmg files after downloading! On 10.4.8 it was not a problem. What can I do?
eMac G4 PPC Mac OS X (10.4.9)

Darn...I thought that would do the trick.
Given the other problems you mention, more and more, it seems a reinstall of the OS, using Archive and Install is going to be necessary. Have you ever done an Archive & Install of the OS? Important you carefully read the description of the process. If you are uncertain, I find the Take Control Upgrading to Tiger E-zine to be a very helpful guide.
Once you reinstall the OS, then you can upgrade to 10.4.8 using the combo update, repairing permissions via Disk Utility in your Utilities folder when complete.
One question: Not sure why you have run into all these problems on the 10.4.9 upgrade. It worked without problem for me. Anything unusual happen during the install?

DMG files I download end up as EXE files

This is weird, now that i have Leopard (after Tiger) when i download DMG files they end up on my desktop as EXE files. 1. i thought downloads were supposed to go in the new downloads folder and 2. why the heck are they downloading as EXE files and not DMG??!! No i did not choose the windows version download.
Please help

Sorted the problem. When i had uninstalled Netscape before, i had not also deleted the Navigator folder found here: User Home folder/Library/Application Support/Navigator.
I backed up my bookmarks.html folder (in a sub folder in the above mentioned Navigator folder) and deleted the rest. I then reinstalled Navigator and put the bookmarks.html file back . All works fine now. I suggest you back up all the Navigator/Firefox files you delete however in case you need anything else

What to do with .dmg files after downloading

I am somewhat new to OS X (however not new to Mac), so this may seem like a dumb question...
After I download an application, plug-in whatever, I have a .dmg file and another icon that looks like a hard drive on my desktop. I know that these are the installer files, but what do I do with them after I install something?
I have been "ejecting" the one that looks like a hard drive, and the other with the .dmg extention I've put in the trash. I put the applications I downloaded and other misc. like the "read me" files together in a folder in the Applications part of the finder.
Is this right? I feel so silly for asking...
Thank You,

Hi
You're doing it right, however: Depending on the application I find it unnecessary to put non-essential files in the Application folder. It is often enough just to put the actual app in the Apps folder. If you archive the .dmg file in a downloads/installers folder in your Home folder, as I do, then you can always access the other misc. files again if ever necessary. It's neater that way, and when the latter folder becomes large I just burn it to disc, file it away somewhere and empty the folder to clear space.

Mp3 files i download are finishing up in a sec wid nothng being downloaded.its wid every mp3 file i download .I tried everythng plss suggest me sumthng. :/

How are you downloading the MP3 files?
Via a direct link or by using an extension?
Did you try to boot the computer in Safe Mode?
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Can't download free trail version. DMG file not recognized.

I am having hard time getting my hands on the free trial of Final Cut Pro X. The dmg file that downloads is only 175 bytes. When I open it, a warning box pops up saying the image is not recognized. Is this an issue on the Apple end of things or mine?

Thanks for the info. That is indeed the download address I have tried using. I do not have a previous version of FCP installed. Is there a way to get a free trial with out having previously purchased a version of FCP? I am new to FCP and would love to try it out before dropping hundreds of dollars.

Corrupt dmg files

I'm having an issue that seems to come up before with others. Every DMG file I have tried downloading is corrupt and is giving me invalid checksum etc..
This isn't limited to one specific machine as I have an iMac and 2 macbooks all try and make the same download on the same network and all 3 are getting the same issues. i've rebooted the modem / router and nothing!
This is really frustrating as I can't get photoshop to work without installing java and even that 60meg download is getting corrupt.
Routerwise i have a netgear WGR614v9 (seems like a piece of crap) and can't get the firmware to update.
This is really frustrating as i need to work from home but can't even install the software i need to use.
Anyone figure out anything?

Add me to the list. Running Mountain Lion on my MBP and Lion on my Mac Mini. The MBP is connecting to the Internet via wireless and the mac mini is wired. Tried rebooting the cable modem and switch to see if that made a difference but it didn't. I cannot understand why unless there's been an update to lion which prevents dmg files from opening a.k.a. The bzip issue that affected osx 10.3 and earlier.
All other file types are fine, it just seems to be affecting dmg files. Also, if it was corruption over the wire then surely web sites wouldn't load properly.
Confused!

Files always download as "attachment.ashx" instead of the file name and file type that they actually are.

Since I have installed the new version of Firefox (version 8.0), every single file I download is downloaded as "attachment.ashx" and won't open. I have to change the name as well as the file type in order to open the document.
This happens regardless of if I'm downloading from email, from a website, etc.. All of the files I have downloaded also have already been named and had file types appended, but Firefox is changing them every single time. I have never had this problem before using the same sites and downloads.

Please hurry up with a solution! This is causing havoc, as I cannot open any attachments at all! It defaults to Adobe Photoshop, and then I get an error message that it is the wrong type of file. These are all Word docs! I can't get my work done! Is there some kind of work around that I can use in the meantime to open these things?

.dmg files not recognised!

I've a lot of program dmg files on a CD as a backup, and since giving my MBP a clean fresh install of Leopard, these dmg files are no longer recognised. Meaning that when I click on them OSX doesn't know what to do with them! It doesn't recognise any dmg files I download from the internet either. I've tried countless restarts but certainly do not want to install Leopard again! Any advice?

+"...Since migrating to my new MBP and Leopard (now 10.5.1), I’ve had to keep reassociating DMG files with DiskImageMounter.app – the setting just doesn’t seem to stick..."+
same here! this is now my fourth installation of leopard; twice with 10,5 and once with 10,5,1 i've installed it, only to 'upgrade' back to tiger after suffering this and a myriad of other teethgrindingly annoying niggles.
when 10,5,2 came out i thought +'surely they've fixed it by now'+ - only to find this infuriating behaviour still exists. no matter how many times i tell leopard to always open all 'dmg' files with +disc image mounter+, the next time i download one, it either opens in +disc utility+ - if i'm lucky! - or the finder complains it disnae know what a 'dmg' file is - if i'm unlucky!
you've really got to admire the quality control of a company which releases an OS which - two point upgrades in - still cannae recognise its own in-house file formats.
oh well, a few more days of this and i then i'll pluck up the energy to 'upgrade' back to leopard again!

Everytime i keep a file to download of high size,it downloads upto half and suddenly it fails to download.! Please fix

I keep high size file to download(mostly videos) and after completing half of the download,it automatically fails to download the file and then it says to retry download.! Please fix

It sounds like that your connection is dropping out while attempting to download the file. Does this happen with every larage file you download, or just some of them?
Another thing you could try is to see if the download works in Safe Mode:

If you continue to experience the same issue in Safe Mode, it could be an issue with your internet connection or Wifi.

Files in Download

After installing downloads can I put such downloaded files in trash?

If you mean the .dmg files you downloaded, then you can delete them if you don't want to keep them.

CS5.5 Production Premium via Akamai or direct download: unrecognised, small .dmg file size

A discussion / open call for help about my experiences downloading the product. This may help
Product:
CS5.5 Production Premium (download version), Intel Based Mac
My system:
MacBook Pro OSX 10.6.8
FireFox 7.0
Safari 5.1
Chrome 15
Problem:
Downloading the 8.2GB .dmg file from order history/your downloads page or opening downloaded file.
1. Akamai shows that "download integrity is invalid". Confirming to start the process over yields same result. Also noticed that filesze is only 202.36MB.
2. "Alternative download method" of direct download results in a 212MB file that is not recognised as a disk image.
3. Speaking to chat support, and going through the above steps again, a direct link was eventually provided, but "access denied" error (to what appears to be the trial version of CS5, not CS5.5). We then had to initiate and cancel a Lightroom download, then go back to the direct link to start CS5 trial.
Download started, but filesize was only 608MB, which cannot be right (no screenshot) No further help on this issue from chat support. I am expecting a call from them, but then I received a case update e-mail saying that they were "happy that we have started the download for Production Premium CS5.5", so not very encouraging.
Also not clearly explained was why I was given the trial. I assume I can unlock the full version with my serial.
4. Via CS5.5 product page, I started downloading trial using Adobe Download Manager. I have to hover over the progress bar to see what the download status is - 15 hours to go. At least it has initiated and seems to be downloading the right filesize. I am hoping I can just put my serial in this and unlock the full version.
Not the smoothest experience so far. I'll update if this works.

(update:) I've also tried downloading other elements, such as CS5.5 master and I've got the same problem. It seems that EVERY downloads stop before the end...
What does it mean? That Adobe doesn't want users to downlaod trials?

Safari 5.1 can´t download dmg files

For a long time I couldn´t download dmg files or open PDF´s in Safari, every time when I tried to open or download a file Safari just opend a black screen and nothing else happend!
However..... I found a very simple solution which helped to solve both problems (Safari 5.1)
Step 1:      Open FINDER -> Macintosh HD -> Libary -> Internet Plug-Ins
Step 2:      Transfer "ALL" files to your desktop! (do not just copy!!!)
Step 3:     Open Safari and empty cache and close Safari
Step 4:     Reopen Safari and try to open a PDF file or to download a dmg file ( at this point it was already working for me again!)
Step 5:     Transfer files from Desktop back to FINDER -> Macintosh HD -> Libary -> Internet Plug-Ins
FINISH!!!!
If you experience any trouble again after Transfering the files back start again by step one and move at Step 5 always just one file to identify the file which seems to create the trouble!
I hope this simple steps helps for you guys as well

These statements require an Adobe Viewer plugin
That's going to be a problem unfortunately, with Safari 5.1
Read here > Apple Safari 5.1 and Adobe Reader/Acrobat Advisory
A workaround according to Adobe is to use another browser.
I personally have found that Firefox works just fine.

I downloaded CS5 yesterday, i uninstalled this and tried to reinstall again today but now it won't let me open 'install' as it says preview already downloaded this from the .dmg file yesterday.

I downloaded creative suite onto my imac yesterday and then tried to unisntall it today as i wasn't sure if i did it correctly. I dont know if i uninstalled it properly. but now when i try to re install it it says that the 'install' is damaged because the .dmg file was already installed yesterday by preview.
Help please
