Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC.
It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility.
When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened
. The reason given for the error is no mountable filesystem
.
However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD.
What has changed in this release to cause this? Is there something wrong with the current ISOs?
The OS X machine I am using is only two weeks old and is having no issues with any other ISO.
ubuntu-12.04-desktop-amd64.iso
andubuntu-12.04-desktop-i386.iso
in OS X 10.6.8 (Snow Leopard) and verified you do get the error message the OP describes. I also mounted those images with no problems using the Daemon Tools and IsoBuster utilities in Windows 7. It appears to be a problem with how OS X mounts an ISO. But I don't know what it is about the composition of the ISOs which results in this glitch..iso
for an earlier version of Ubuntu? If so, then Fufus Rufus's answer about why this is happening is probably correct.ubuntu-8.04.4-desktop-amd64.iso
andubuntu-10.04.4-desktop-amd64.iso
mounted as expected.ubuntu-11.10-desktop-i386.iso
did not. I got the same error message as for the 12.04 ISOs.
