Folks, I'm curious if anyone has seen a similar issue installing beta 1 of High Sierra. I have a rMBP, early 2013. The installer begins to run and notes that a specific amount of time is left, in my case between 34 and 35 minutes. After maybe 3-4 minutes of this, it will then state that it is 'calculating the amount of time remaining' and do this for maybe 10 minutes at which point the installer window states that it can't install the software and the error message is OSStatus 2 (which I thought was a time machine error). The logs state that it is unable to mount one of the images for install (InstallESD.dmg). I tried a repair on the SSD. The DMG highlighted below is definitely there. Repairing the SSD actually fails, not sure why. I can reinstall Sierra but I haven't actually done a rebuild of the disk and then a reinstall. Maybe I should try that but wanted to know if anyone had insight.
But try as I might, I could not that make that drive mount reliably on my machine. I could plug in the drive into one of my USB ports and the green drive light would go on and you could hear it whir to life, but it never mounted. The System Information and Disk Utility never showed the drive. How can I open a.dmg file? Ask Question Asked 8 years. The application seems to convert.dmg to a file that can be mounted using the mount command: dmg2img file.dmg imagefile.img. 1, and when dmg2img's output won't be accepted by mount either. I'll clarify – cat Feb 19 at 21:24. To mount/manipulate the DMG without conversion, you could use HFSExplorer. It comes as freeware, and has a decent set of options and features. Since your working on Windows 7, 7-Zip is the only other option I see for your situation.

DMG files are containers for apps in macOS, from which you can install software fast. Installing software simply requires you to open the .dmg file and then drag the application to your Mac’s Application folder. That’s much easier than using an Install Wizard in Windows. However, some of Mac newbies have no idea how to mount .dmg files in macOS or for some reason the .dmg file cannot be opened. Now this page will show you three methods to open and mount .dmg files on macOS.
Method 1: Open .dmg file with DiskImageMounter
DiskImageMounter is the utility that handles mounting disk images in Mac OS X. Normally you can mount a .dmg file on Mac by simply double-clicking it or right-clicking on it and selecting Open With > DiskImageMounter (default). However, some people report that .dmg files cannot be opened on Mac in this way. If that’s the case, move on to another method.
Method 2: Mount .dmg file from Mac OS Terminal
Damaged Dmg File Won T Mount
Place the .dmg file on your Mac’s desktop and then follow the steps.
Step 1: Open Terminal on your Mac. If Terminal is not on the Dock, open it from Finder > Applications > Utilities.
Step 2: Type cd ~/Desktop and press Enter key.
Step 3: Type hdiutil attach googlechrome.dmg and press Enter key. Replace googlechrome with your .dmg file name.
That’s it. After you execute the two command lines, the .dmg file will be mounted on your Mac.
Method 3: Mount .dmg file using iSumsoft Bitlocker Reader for Mac
If you cannot open .dmg files on your Mac using either of the first two methods, it’s a good idea to use a third-party utility like iSumsoft Bitlocker Reader for Mac. iSumsoft Bitlocker Reader for Mac is mainly to help unlock BitLocker-encrypted drive on Mac, but it also comes with the Attach feature that can attach disk image on Mac. Here are the simple steps you can take to mount .dmg file using iSumsoft Bitlocker Reader for Mac.
Step 1: Download and install iSumsoft Bitlocker Reader for Mac on your Mac computer. After the installation is complete, launch it from the Launchpad.
Step 2: Click the Attach button.
Dmg File Won T Mount Permission Denied
Step 3: Browse for the .dmg file and select it, and then click Open.
That’s it. The .dmg file is now mounted successfully on your Mac and you can open it. You can also click the Unmount button to unmount the disk image from your Mac if you want.
