MacBook Pro :: Downloaded DMG Files Don't Open

Apr 3, 2012

I have had some trouble lately when downloading DMG files with Safari. In the URL bar I could see it was downloading and then downloaded however nothing happend. Changed to open with DiskUtility didn't do anything. Firewall had no influence. When downloaded with Firefox there was NO problem and everything went fine like it use to do with Safari. So I suspect it is a bug in Safari since this happens with all DMG files of late.

PowerPC :: Cannot Open / Unmount DMG Files

Apr 23, 2008

A few months ago my cdrom started not wishing to eject my cd stating it's in use (when it isn't). It shows up on my desktop fine, but won't eject. I have to restart and hold down the trackpad button for it to release the cd. That was all fine and dandy and though annoying I can deal with it...however... My computer is not allowing me to open up .dmg files. I have stuffit...I have the standard diskmount that is default in mac computers but when I tried to download firefox and another program they put a .dmg file on my computer but neither will open up and unmount! So why would a download not unmount...nothing for a .dmg is unmounting on my computer. I tried opening stuffit and it appears like it'll open but doesn't...stays in finder just like when I try to unmount the files. Now that I have the .dmg on my computer I want to delete them because if I can't unmount them they're of no use to me. However, my trash won't let me saying they're in use.

Software :: Cannot Open DMG Files - Disk Image Failed To Mount

Feb 27, 2010

I'm using a 2GHz PowerPC G5, OS X 10.4.11, with 1 GB on one dimm. I cannot open ANY .dmg files. I have tried clicking the image, and also on a clean download used "open with" each time I received the following message The following disk image failed to mount
Reason: Device not configured

I have followed the instructions in this thread:- Disk image failed to mount: Device not configured.
Firstly Run /Applications/Utilities/Disk Utility.
Click on "Macintosh HD" in the left column and then press the "Repair Disk Permissions" button.
Delete the file called /System/Library/Extension.kextcache
Delete the folder called /System/Library/Caches/

That made no difference. I then tried bobw's advice here Panther - Disk Image "mounting Failed" Panther - Disk Image "mounting Failed". That made no difference. I have since gone on to and the advice I received was to do an archive and install and then a full combo update.

Software :: Can't Download .dmg Files

Jun 9, 2008

^^That's my problem, tried different browsers and different users (note: both were admins), nothing works.
As an example:

I got to -> [URL]

Then click on Download iArchiver, the browser screen goes white (not everything, just the 'display' side of it), and it keeps loading and loading with the [URL]

It also sometimes makes a difference if I 'Block pop-up windows' or not, if I don't, the already described happens, otherwise it simply goes back to the window where I clicked on 'download' (note: this has happened so far only while trying to download firefox and blocking pop-up windows)

OS X V10.7 Lion :: Won't Mount DMG Files Unless In Safe Mode

May 7, 2012

If I try to mount almost any DMG file I just get an error message saying that there is no mountable file system. I know that these are not corrupt dmg files because these are ones that I have mounted before, it affects almost every single one and more importantly if I reboot in Safe Mode every single one mounts perfectly. 

Clearly then something is running in normal mode that is preventing dmg's from mounting but I don't know how to find out what. I went to System Properties>User & Groups>Login Items and removed everything that was there but that was just iTunes Helper and something called WDC something or other which was unchecked anyway and is just a utility that controls my external hard drives. With everything removed and rebooted still DMG files won't mount. 

Safe Mode = DMG's mount

Normal Mode = DMG's won't mount. 

how I can find out what is causing this problem and/or how to fix it as it's annoying as **** and preventing me from easily updating software.

MacBook Pro :: Open / Mount Compressed Dmg File

Jun 18, 2012

I recently sold my MacBook Pro, but before doing so I made a compressed image of the hard drive via Disk Utility so I would have access to the files once the laptop was gone. The file was roughly 460GB compressed. The file has been stored on my Drobo.Now I'm trying to mount the image so I can move things over to my new computer but I'm having trouble getting the image to mount, convert or anything. Typically I get a message to the effect of "no mountable filesystem found".

Apr 6, 2009

When trying to download .dmg files through my browser (for example- when downloading the trial version of iWork on, or when trying to download the app from this site: ), my screen will usually say "thank you for downloading" or "your download will start momentarily," but the download doesn't start. I have this problem with both Safari and Firefox. Are any of you guys out there experiencing a similar problem? If so, have you been able to fix it?

OS X :: Mess With The File Name And Open The DMG Manually?

Aug 22, 2009

When I download a DMG via Safari, the usual steps once the download completes is "verifying disk image...mounting disk up" and then it should be complete in the downloads window. however, i've been having this issue where the download gets stuck at "cleaning up". to get it to get out of the download window, i have to quit out of safari after it asks me if i'm sure i want to quit since there is an active download in progress (even though it is technically done downloading).

the files are labeled with the .download extension so i have to mess with the file name and open the DMG manually. does anyone know about this issue and how i can fix it? it is a nuisance to me and i don't recall when it first started.

MacBook :: Why Can't Open Files With Double Click

Mar 25, 2012

I have been having problems with my MacBook (Aluminum late 2008, I think, OS 10.5). It runs slowly; files on the desktop and in my "Macintosh HD" often won't open with double-click but have to be opened with File-->Open; there are Word Work Files that won't go away; the trackpad is often stiff and not very responsive; clicking on the mouse is very stiff, despite very easy settings. In short, a lot of things are sluggish. Sometimes, also, I get the spinning beach ball, but not all the time. 

I have run disk permissons repair from Disk Utility many times (both from the desktop and from the MacBook install disk); I have replaced the directory with Disk Warrior at least twice; I have verified that the disk is OK; I have zapped the PRAM; and done other things of that kind. 

I took the MacBook to an Apple Store yesterday. It had been unplugged and much to my surprise, most everything seemed to be working all right. When I opened it today, however, I found everything as it was before I took it to Apple. Including the Word Work files, which I thought were gone. 

If I recall correctly, this started when I was working on a long editing project in Word, but I don't know whether that has anything to do with what has happened. I've done similarly long projects before, and this never happened. 

I could try trashing the Word Work files (there seem also to be quite a lot of folders with "recovered" files), but I don't want to do that unless I can be assured that nothing bad will come from doing that.  

I know this seems quite comprehensive, and may involve several issues, but I'm really unhappy about this and would love to think there is something more I can do, apart from returning to the Apple Store. Besides everything else, how can I khow that I won't find, again, that the MacBook will work fine there but goes back to its troubled state when I return?
