Thank you, both of you!

It might have something to do with my Apple ID, which I share between both my computers. I tried downloading and opening the .dmg file in my main computer, and it worked fine.

Still don't know the problem, but at least I was able to open and play the game.

Hello

I run OSX El Capitan v. 10.11.6 on my computer.

I've downloaded both UQM 0.7.0 and UQM EE 0.6.4 from Sourceforge.  However, I can't even open the file to install on my computer.

For USM 0.7.0 I receive a message saying:
Netplay protocol version 0.4. Netplay opponent must have UQM 0.6.9 or later.
Error: Can't create /Users/******/.uqm: Permission denied

(my name appears on the message instead of ******)

For UQM EE 0.6.4, I simply can't open the .dmg file at all.

Please help; simple Mac user here.  I have no experience using Terminal or anything to manipulate the code / permissions / anything on my Mac

Best,
