Description
Some DMG cannot be mounted in a VM with a "VERR_VD_DMG_INVALID_HEADER" error. Example XQuartz-2.7.11.dmg, but there are actually the majority. The validity of each of the DMGs has been verified. Full error message:
Could not open the medium "/Users/Shared/_Downloads/_System/XQuartz-2.7.11.dmg".
VD: error VERR_VD_DMG_INVALID_HEADER opening image file "/Users/Shared/_Downloads/_System/XQuartz-2.7.11.dmg" (VERR_VD_DMG_INVALID_HEADER)
Other examples include:
- Any DMG created from the Disk Utility will not mount. I believe I've tried all possible combinations, but they all fail with the above error message.
- Xcode 7.3.1, that's actually the weirdest. The VM (OSX) shows a "
The disk you inserted was not readable by this computer. Ignore | Eject". If you copy the same exactly DMG in the VM, it is mounted and works as expected.
