Shotgun I have not played it in GO yet.
Also i took the time to grab the error code so this issue can be resolved if it is a server error (possibly specific to mac?)
Host_WriteConfiguration: Wrote cfg/config.cfg

Missing map maps/de_season_gome.bsp, disconnecting

Donator, I tried deleting the file after and that did not help.
SOLUTION: I HAD TO MANUALLY DOWNLOAD AND ADD THE MAP FILES.
Also i think many would benefit if there was a perm-thread/link for all the Darkly Map files?
