Well after about a month i finally got my MacBook Pro (2008) to work. One of the first things i did was to start PA. I was really exicted for all the updates i have been missing the last two months, but when i started a two planet game, it crashed immediately at start. This never used to happen i thought. So i started a GW and started a match on a single planet system, same issue. I belive this shouldn't happen. Considering i have 8gb of RAM and it used to work fine being able to play on 4 planet systems before. I'm running OS X 10.9.3 on my MacBook Pro (2008) with 8gb of ram and a 2,66GHz Intel Core 2 Duo.
I experience just the opposite. In v69721 they reduced the size of the code, and the game is much faster now. I can play on larger systems with more units than before. It is definitely more playable now. I guess your issue has something to do with the display driver or perhaps you are using an older OS version.
If you think the memory usage is the problem, did you try SXX's memory reduction thingy? See his thread.
Yeah, it's not a particularly easy thing to do. You would need to find the location of CoherentUI_Host and replace it with the script. Unfortunately, I'm not exactly sure where it lives on a Mac either. I think Finder hides these things for you, so you'd need to be comfortable with using the terminal. If you do find out where CoherentUI_Host is located, then you can type this in the terminal: Code: cd path_to_coherent sudo mv CoherentUI_Host CoherentUI_Host.bin ( echo '#!/bin/bash'; echo 'ARGS="--single-process"'; echo 'exec -a "$0" "./CoherentUI_Host.bin" $ARGS "$@"' ) | sudo tee CoherentUI_Host sudo chmod +x CoherentUI_Host Where you need to replace "path_to_coherent" with the path to wherever you found CoherentUI_Host.
