MacBook Pro running OSX 10.11.5 downloaded freebie PreSonus Studio One 3.dmg.  On clicking, a Warning window displays 'The following disk images couldn't be opened:  Image - PreSonus Studio One 3;  Reason - image not recognised.

Any assistance appreciated, thanks

Try going in to your Security & Privacy options in OSX. Under the General tab you'll see a section that says "Allow apps downloaded from:".

Try setting it to "Mac App Store and identified developers" or perhaps "Anywhere" if the first option doesn't work.

This should allow you to install.
