Macintosh HD, or the MacBook internal hard drive, is basically the startup drive of most Apple computers. That means if your Mac or MacBook Pro can't mount its startup disk, it is likely that you will experience problems, like your computer gets stuck on the login screen or it does not boot at all. After you mount image, Mac OS is able to see the content of the virtual disk and work with it just like with any other physical media. I would like to explain how to mount an image on Mac and how to use the images. To mount a disk image, Mac uses a special utility. With it you can just double-click on the needed image to mount it.
To use it, right-click an.ISO file or another type of disc image, point to Open With, and select 'Disk Image Mounter.' You can later unmount the image by clicking the eject icon next to the mounted image in the sidebar. You can also mount an.ISO file or another disc image with a Linux terminal command. Summary: After downloading Rhino for Mac the download reports the disk image could not be opened. The Rhino for Mac download has been corrupted during the download. Go to download and request another download link. A disk image contains all of the data on a physical disk with an identical file structure. The ISO format is a very common format for disk images. Mac programs often use the CDR or DMG format for disk images, however cross-platform downloads as well as CD and DVD disk images may come in the ISO format. The Finder in the Mac OS X operating.
I have a mid-2010 MacBook Pro that I am wiping for a family member so that they can sell it. It was connected to care patient data at one point so I want to make sure it's good and clean before we sell it. So I booted under Disk Utility and wiped the 'Internal Drive' by going to erase and setting the security options.

But there is a drive under 'Disk Images' called 'Apple disk image Media' with 'OS X Base System' under it, using 1.27 GB with 728 MB free. Just wondering what this is, and if it would have info on it? How can I delete it? I don't see any way to erase it and it isn't mentioned in any of the guides I've read.
The Mac did have Boot Camp on it, which I deleted through the OS. Not sure if it's related.

Open Disk Image Mac Osx
I ran into an interesting macOS error while working with a customer a couple of weeks ago. I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself.
Acrobat adobe dc sign in. The error was as the screenshot above shows; trying to open a dmg (disk image), macOS showed the error 'no mountable file systems'. If you see the 'no mountable file systems error' while opening a dmg, here's what you should try:
In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try
curl -O url
in Terminal to download the file. (There's an example of that in my screenshot below.)Reboot your Mac if you haven't already tried that. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot.
Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:
Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.
Type
hdiutil attach -verbose
into the terminal. Add a space at the end, but don't press enter yet.Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.
- Press enter.
macOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to
Apple_APFS
or error112
, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.Here's an example of the end of
hdiutil attach -verbose
output that shows an APFS error due to an older version of macOS:Think about if you have any kind of security policies on this machine to prevent writing to external drives (thumb drives, optical drives, etc). I haven't seen this one in action, but I read about this being a possibility while researching the issue.
Another suggestion added by a reader (thank you, Markus!) is that filesystem errors on your main Mac drive could be the cause of the disk image mounting errors. Here are instructions from Apple for scanning and repairing errors using Disk Utility. Note that in order to scan and repair errors on your main Macintosh HD drive, you'll need to reboot your Mac into recovery mode. You'll want to choose Disk Utility in the utilities listed in the recovery mode menu.
A new discovery from a reader (thank you, Colby!) is that APFS DMGs won't mount if you're booted in macOS booted in Safe Mode. (Who knew!?!) If you're not sure if you're in safe mode, select the Apple menu > About This Mac > System Report button, then select the 'Software' heading from the left column. To exit safe mode, restart your Mac, without holding Shift during startup. Or, if you previously set your Mac to always boot into safe mode using
nvram
, turn off safe mode and have your Mac boot normally on the terminal:Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.
Type/paste
sudo nvram boot-args='
and press enter.Play free roulette game. Restart your Mac.
