TripleA 1.6.1.4 stable is released for Christmas 2012!

you can have 2.5, which works in the lobby, and the prerelease both installed. The prerelease won’t work with 2.5, so switch back and forth if using a save from the prerelease and lobby games.

@Zhukov44

Yes, you need a current 2.6 pre-release to be able to post to the forum. Also AFAIK with 2.6 the map-download procedure and lobby will change, that is why you are stuck to 2.5 for using those. Installing both versions side by side is a good workaround.

Enjoy your games, now.

@panther OK, thanks.

There is nothing bizarre on this part of the posting linked above:

@Veqryn:

Alternative instructions for unblocking TripleA:

http://support.apple.com/kb/HT5290

1. Open up “Gatekeeper”
Gatekeeper options are found in Apple menu > System Preferences… > Security & Privacy > General tab under the header “Allow applications downloaded from:”

2. Change “Allow Applications Downloaded From:” to “Anywhere”

3. You should now be able to open and use TripleA (and any other software).

Did you try that?

Also be sure to have the latest version of the Java Runtime Environment installed.
I don’t know which version comes preinstalled with your OS.

I was going to ask, is this feature going to be made available soon?

Come on over to the homepage and post your question- it’s an active community and I’m sure you’ll get help.

Just to sum up what happened at the end of this thread:

TripleA is very much alive. It got purged of any name references to the boardgame, but the maps resembling the official boardgame in setup support the complete rulesets of all the versions out there.
More important, in my eyes, it features some user made maps with different themes. Some of them are aimed at the advanced player (like New World Order - NWO1.7EB, for example), with the positive side-effect of having a mannered and above-average skilled community around them. The large maps tend to value strategic thinking above tactical assessment.
