On osx, I cannot mount image

I got a warning
" disk not recognized "
and can not mount image.

I’m using macbook pro OS-X 10.9.2, 16G memory

Go into your terminal and use curl to download it.

To get the link to the file, go to the download page, right click the download for OS-X button and click ‘copy link address’. Then just enter into your terminal "curl " (without the quotes) and press CMD+V. Then press return, the file will now download. After that’s done, it will be in your home folder, so just mount from there.

Please see Mac OS X - Disc Image Not Recognised - Platform & Builds - Epic Developer Community Forums

Usually is more reliable to use “Disk Utility” also make sure downloaded file is not corrupted.
