In Disk Utility I see two disk images (Flash Updates)

enter image description here

But I cannot find where the image file could be.

On the console with diskutil I see

/dev/disk2 (disk image):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        +16.9 MB    disk2
   1:        Apple_partition_map                         32.3 KB    disk2s1
   2:                  Apple_HFS Flash Player            16.9 MB    disk2s2
/dev/disk4 (disk image):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        +17.2 MB    disk4
   1:        Apple_partition_map                         32.3 KB    disk4s1
   2:                  Apple_HFS Flash Player            17.1 MB    disk4s2

And with diskutil info

   Device Identifier:        disk4
   Device Node:              /dev/disk4

Is there a way to know where these images are on my disk?

  • Does clicking on the actual disk image (Apple UDIF...) show where it's at? On the old disk utility, it would be there.

  • The eject command works. I had 2 of these relics for some time.

  • Hi, the question is not on how to eject them but where the dmg files are on the disk.

  • Try selecting the disk image icon rather than the unmounted volume icon (which is what the image above shows). At least in previous versions of Disk Utility, that shows info about the disk image file (.dmg). You can also right click on the disk image icon and choose Eject. Not sure if that still holds true for El Capitan or not...

The question is actually "How to remove...".

It can be ejected by using the device path

diskutil eject /dev/disk4

Substitute disk4 for whichever disk is offensive.

    Thanks John2095 that worked for me on my MacBookPro running El Capitan. Just encase people have not done this before this what to do - open the Macintosh HD/Applications/Utilities/TERMINAL.APP - then just type diskutil eject /devdisk2 substitute disk2 for whichever disk you want to eject like John2095 said.

Mount them through Disk Utility and you will see them in Finder where you can just unmount them by clicking on the eject icon in the sidebar next to their names (in Finder) and they will disappear.

    Thanks for the answer! But it doesn't actually answer the question that was asked.
