I'm getting crashes on startup on Mac OS 10.7.5. App window never appears, log file in ~/Library/Application Support/factorio is not updated, but syslog shows stuff like:
Oct 1 04:27:15 homemac [0x0-0x2b24b22].com.factorio[62647]: unrecognised option '-psn_0_45239074'
Oct 1 04:27:49 homemac [0x0-0x2b27b25].com.factorio[62657]: unrecognised option '-psn_0_45251365'
Oct 1 04:29:05 homemac [0x0-0x2b28b26].com.factorio[62723]: unrecognised option '-psn_0_45255462'
I'm pretty sure this is some flag the OS is adding when opening the app using the Finder. I can get the app to run fine by directly executing factorio.app/Contents/MacOS/factorio from the command line, but it's annoying to have to start things that way.
This is in the current 12.9, but it seems to go back to 12.5 for me. Not sure why, but 12.4 is fine, even if I execute it directly and pass it a random -psn flag. Later versions of OS X (I have a laptop running 10.9.x) also seem fine for some reason.

Thank you for the report, this will be fixed in the next release.
