I am trying to install Sage 8.3 on OSX (latest version, 10.13.6)

I usually download the disk image and drag to Applications, so I attempted this with the file


and checked that the MD5 checksum matched the advertised MD5 sum on the download page.

On opening the disk image, a dialog saying "Verifying" opens up, and starts to verify, but then halts with an error message that I have not seen before:

"The following disk images couldn't be opened, (name of file), image data corrupted"

I downloaded again, and once again the MD5 checksum (called from a terminal window) was correct.

Then I ran Apple's "Disk Utility" and attempt to verify the image, which failed and produced a bunch of diagnostic data that I do not understand. (I have attached this diagnostic output in case it may be helpful)

Any assistance gratefully received.

Diagnostic output from "Disk Utility" starts here:

I don't know if anyone else has reported this problem. But if not then I suspect it is a problem with your machine.

Beats me I don't build the OSX images. @slelievre?

Same here... Image data corrupted. Quite annoying

Okay. It's probably a problem with the build then. I don't know how to fix that but I'll ask who can...
