We have reports that our .dmg images are not mountable on some macOS systems (one report for 10.12.5 ( and one for 10.9 (

The error message is something like:

image could no be mounted

no mountable file system

This happens while other .dmgs work fine on those systems.

I wonder if some devs/users being on macOS can shade more light on this issue given that it seems to happen only on some systems.

I do not have any idea what is causing this problem. It must be somewhat rare, but it seems like a big problem for those who encounter it. I wonder if there is anything special about the file system where the DMG resides or if any antivirus or antimalware software is installed?

Duping this over to #29470 which has a workaround.
