Firefox won't save DMG files and won't mount the disk image. Why?

When I try to install a download I am asked to either save the DMG file or Open using .... I select save, but the disk image never appears on my desktop and nothing shows in the Tools-Downloads window.

See if this helps you: <br />

The latest Pages won't save new docs and won't open some old ones. What do I do?

Then you have two version of Pages on your Mac.
Pages 5.x is in your Applications folder.
Pages '08/'09 is in your Applications/iWork folder.

"Lightroom_5_LS11_mac_5_7.dmg" for Mac to update my Lightroom 5.6 (build 974614) but when I attempt to open it I get the following error message "Lightroom_5_LS11_mac_5_7.dmg can't be opened as the disk image is not recognised". I'm running Yosemite OS 10

I have downloaded "Lightroom_5_LS11_mac_5_7.dmg" for Mac to update my Lightroom 5.6 (build 974614) but when I attempt to open it I get the following error message "Lightroom_5_LS11_mac_5_7.dmg can't be opened as the disk image is not recognised". I'm running Yosemite OS 10.10 on a Macbook Pro (Retina, 13-inch, Late 2012 with 2.9 GHz Intel Core i7 processor).

Vk2mh it sounds like the download was not complete or corrupted. Where are you downloading the update from? Have you tried downloading again?

I downloaded Firefox 4, it came in as a .dmg file and won't open what will open it?

when I double click on the dmg file I am question wh\at program do I wish to open in.
I can't get to the firefox icon to drag to my applications folder

You are not in the Safe Mode, you are in the Offline Mode. I don't know what OS are you on since it doesn't show in your system details:
If you see a Firefox icon, click on it and then go to:
File > UNCHECK the Offline Mode
If you have a Menu Bar instead, do the same.

I lost my original disk for photoshop 7... I need to update.. it won't let me.. and keeps asking for the disk.. even though the program is on my pc... How can i get my update?

I have photoshop 7 on my pc but have lost my original disk.... I went to update it and the update is not seeing the file on my pc... and it keeps asking for my disk.. but i can't find it...
How can i update it...

Ah, you had Photoshop 7.0 working, and now it's not. I see that as a separate issue to updating it. I'm not sure why it would ask you to update it.
Do you know whether you have 7.0 or 7.0.1 at this point? You might be able to do a Properties function on Photoshp.exe and see that info.
You could make an attempt to reset Photoshop's preferences to defaults. Press and hold Control - Shift - Alt simultaneously immediately upon cold-starting Photoshop. If you get the keys down quickly enough - and you have to be really quick - it will prompt you to confirm deletion of your current preferences, which will lead to the establishment of a fresh default set. If it does not prompt you, you haven't been quick enough to get the keys down.
Only other thing that comes to mind is to use Windows System Restore to restore back to a restore point where Photoshop was working, or restore from a backup (you do make backups I hope).
If that fails, and you need to do a fresh install but no longer have the original disk and serial number I'm afraid you may be out of luck. There's no place I know of from which to download a fresh full copy of Photoshop 7.0.

How do I mount a disk image that won't open?

I have an external drive Samsung 500 GB that was failing. I think my MacBook Air (10.6.8) caused it to fail because it wouldn't allow me to eject the disk even though I forced quit all programs. I eventually had to just unplug the drive and this caused the external disk to fail as it had not been ejected properly. Not my fault. It's the MBA's fault for not letting me eject the disk. Now the Samsung disk won't mount properly and I get a message that the drive is failing and I should save the data.
Anyhow, I used the free version of Data Rescue 3 to try and save the data on the failing Samsung 500 GB drive and move it onto a brand new Toshiba 1 TB drive.
I was unable to use the normal scanning function of Data Rescue 3 as the hardware of the drive was too damaged, and so I used the clone function on Data Rescue 3 to clone the data onto a non-failing hard drive, with the intent of restoring the data later.
I am not sure if I was successful in making the disk image. It hung up at the 99.6% point for about 12 hours when I decided to give up on it, and I shut down Data Rescue so I could eject the hard disks.
However, it would not let me do it. I tried force ejecting but still I could not eject the disks.
I ended up just unplugging the drives. I think the Samsung drive died almost completely then because it made a whole lot of clicking noises after that (it was only making a few clicking noises before that).
Anyhow, I plugged the Toshiba 1 TB drive into the computer again and used Data Rescue to scan the drive with the disk image on it to see if I could detect files on that drive.
It opened up the structure and I was able to see that most or all of the files were there (abbout 450GB of data) just from seeing the information about the files in the structure tree - the labels of the files (file type labels such as jpg, mp4 etc) and the size of the files, although I could not open up the files to check all of them.
I tested out the restore function of Data Rescue by downloading one file (<10MB) file. I am using the free version and can download one file for free to test things out.
It worked and I was able to save that file onto a second external drive (Western Digital 500 GB) I had plugged in. I had bought this drive just to do the data rescue.
So I think the files are salvageable and the disk image is OK.
However, when I tried to open the disk image in Disk Utility, by opening it as the source and choosing the WD drive as the destination I could not open it. I got an error message. I can't remember what the message was.
I tried just opening the disk image in Finder by just clicking on the disk image but it won't mount.
Is that because my hard drive doesn't have enough space? My Desktop on the MBA only has 12 GB free and the WD drive has only 500 GB on it even though the disk image is about 501 GB.
I don't know why the disk image is that size when the failing Samsung drive only had 450 GB of data on it.
Anyway, what should I do to mount the disk image?
I want to mount the disk image so that I can copy or move the files from it to another external drive so that I can save those files.
Is it because the WD is only 500 GB or does it mean there's a problem with the disk image I made?
Should I try Carbon Clone Copy? I use that to make backups of my MBA internal HDD though I have never used it for opening or making disk images.
I have never dealt with disk images before except for dmg files of applications downloaded from the internet.
I am trying to avoid using Data Rescue 3 as I have to pay for it and if there is a free option, such as Disk Utility, CCC or other, I want to try it to restore the data in the disk image.
Sadly, I think the Samsung drive is ruined beyong repair as it's making a lot of clicking sounds and doesn't mount properly in Disk Image and I get a message that it's beyond repair or something like that in Disk Utility.
So I am relying on the disk image I made on the Toshiba drive to restore my files.
(I think it was the last movie file that caused the problem because it was when I was trying to copy it onto the Samsung external drive, all the problems began - hanging up when copying it, not being able to eject the Samsung disk, causing hardware issues on Samsung disk and getting warning messages on Disk Utility.)
BTW, I learned how to eject a drive when it won't eject the normal way, I have to use command window and type in commands, but that's another post ....
Any advice?
I am thinking of going out and buying a second 1 TB external drive so that I have a disk with enough space to open the 501GB disk image on it, just in case that was the sole problem.
However, I am not sure that is the case, and I think there may be a problem with the disk image or I am not going the right way about opening it.
Thanks for any advice.

I think I've found the solution to this problem.
http://superuser.com/questions/19426/im-unable-to-mount-a-dmg-getting-a-no-mount able-filesystems-error
I am following the instructions here:
I ran into a similar situation. I did what simonair suggested and I received a message in Terminal that Volume mounted successfully. However It did not help me access the mounted Volume neither was I able to confirm the mounted Volume. Nor was I able to mount the image using Disk Drill or even scan through. Nothing succeeded.
Here is what I did to solve my problem. I see that in this post some suggested that we should convert name.dmg to writable file. I used the command from Terminal to convert but was not successful. INSTEAD alternatively, I used Disk Utility, attached the Volume (yes I got the same message again, ''no mountable system files'' however, Disk Utility nevertheless attached the image, which I was able to do before anyways. This time, I selected it and then clicked New image, and then selected image format read/write, not the compressed option. I created a new image. This time this image was writable however, it still would not mount using Simonair's solution. However, this time I was able to scan it with Disk Drill with exact file locations and folder hierarchy as I had. Recovering all from thereon was a breeze. Just remember: when you create new image of an attached volume and chose not compressed but read/write, you need to have a disk with exact amount of space that totals the total space allocated within that name.dmg file (not the amount of space the data takes). Mine was huge, and luckily I had an external disk with enough space to do that and it took about 5 hours for about 400GB of disk allocation. Good luck.
And so far it seems to be working. Even though the volume is grayed out on the left side of Disk Utility, I am still able to select it as the source for making a new disk image. I chose Read and Write and no compression.
The only thing I might be doing differently is that instead of choosing the disk image as the source, I chose the volume as the source. The volume is grayed out, but the disk image is not.
It seems to be working all right. Keep my fingers crossed.
If this doesn't work, I will use Data Recovery 3 as a last resort.

I run OSX10.6.8. Just dwnlded FF8.1 and everytime I go to open it I am asked about the disk image. But if I delete the dmg, the program won't run.

I just downloaded the 8.1 version. It was a 30+mb file. Previously I ran 4.0. So I drag the new Firefox icon into the Apps folder. It does its merge thing with the old version. Problem is when I click to open FF now, it always throws up this window asking me about the disk image of what I just downloaded. I even tried restarting the computer--but the same message pops up. I checked on your website and it says that I need to "eject" the disk image (i.e. I'm guessing that means the 30+ mb file I just down loaded), so since I don't have an eject option that I can find (except for external harddrives and cd/dvd), I just drug it into the trash. I go to empty the trash and I get a message that that dmg file is "in use" even though FF is completely shut down. So again I'm guessing that means that even though I already merged that dmg file with the old 4.0 version file, if I dump the update file it seems that it's going to mess up the actual revised program file still remaining. I just want to be able to click on the icon in my dock like I've always done and have FF open. I don't want to keep being asked about disk image stuff. Somehow this feels like an easy resolution, but I just can't seem to put my finger on how to resolve it. Thanks for you help.

Nope---didn't work. I've owned Macs for about 12 years so although I am brain dead on some things, I do have a working knowledge on most things. I only say that to say this--I did try holding down the mouse and choosing empty trash. It asks if I want to permanently delete what's in there. I say yes--and then I get the same identical message again-----'The operation can't be completed because the item "Firefox 8.0.1.dmg" is in use I can then click stop, or continue.' So apparently that complains the same way it does if I click it up on the menu :)))
As for item owned by---that's not an issue and isn't coming up. User is not a problem either as I am the only user on this system. There is only ONE file in my trash at the moment at that is this dmg file. Nothing Mac. Nothing owned by anyone other than Firefox. The problem seems to be that the dmg file and the original 4.0 FF file are working in tandem with each other--even though I have already drug the new 8.0 globe into the Apps folder and it updated the FF app with the new stuff. If I could force the dmg file to go away, I would do so, but at every turn the system is telling me it can't be done because it seems to think that dmg file is in use---even though everything is shut down and/or ejected. Hey--I'm getting ready to head out and won't be back till evening. I'll check back in this evening. Thank you again for your help.

When in firefox this comes up-your computer is low in memory. Save your files and close these programs.

The available RAM memory on our computer no problem. And we have over 50 gigs of hard drive memory. We have also cleared off history files and open programs. But when my wife plays games on facebook, farmville and the new one just out, a pop up says 'your computer is low on memory. Save your files and close these programs- Fire fox. Our internet security is fully functional and a complete diagnostic has revealed no malware, viruses, trojans, on our system.

Hello,
According to the error message, it should be a Windows issue.

Many Thanks, Kurt.
I knew I'd seen the solution you've provided somewhere - either in MacWorld or MacFormat - but couldn't remember the Gatekeeper bit!
I shall save it somewhere VERY safe now in case this happens again …
You have made an old man very happy and saved me from worrying that senile decay had suddenly set in. (I was 70 last week so you might understand the situation from that.)

Firefox 8.0.1-4.dmg - downloads - could not be opened. Quick Time Layer cannot open files in the "Disk Image" Format - What do I need to do?

I get the above message when I try to download Firefox updates.

That is a disk image file and you can't open that in an application.
<br />
Make sure that Firefox gets installed properly.<br />
Open the Firefox disk image (DMG) file with a double-click if necessary and drag the Firefox program to the application folder on your hard drive.<br />
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

My ITunes won't sync my ipad and closes down in the middle. I have Windows 7 Ultimate. How do I fix this problem?

My itunes won't sync my ipad and closes down in the middle of the attempted syn. I have windows 7 ultimate. Any ideas about what to do?

If the steps above do not resolve the issue, attempt to sync with iTunes while logged in as a new admin user. Follow these steps to create a new administrator user within Windows:
From the Start menu, choose Control Panel.
Open User Accounts.
Select Create a new account and follow the instructions to complete the account setup process.
Once the new account is created, choose Log Off from the Start menu.
Log in to the newly created user account.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If these steps do not work at all, I would suggest calling AppleCare at 1-800-275-2273 (assuming your iPad is stilll within support or has an AppleCare Protection Plan) and let them know you have already tried all troubleshooting steps per TS2830.
