Linux/MacOS Installation Instructions

To ensure a proper operation of Linux and Mac FMJ clients please follow this guide:

1. Mac & Linux

The problem of not being able to connect to a server may be related to permissions on the 556mmfmj folder and the PK4 files. I installed my copy as the “root” user and when I run it as the"{your logon name}" user I get the “missing files” problem connecting.

The permissions need to be set as follows:
556mmfmj folder: owner=Read, Write, Execute group=Read, Execute, Sticky other=Read, Execute

PK4 files:
owner=Read, Write group=Read other=Read

Easiest way to do this (on Linux, should be similar on Mac) is to open a Terminal as “root” and then…

cd /usr/local/games/doom3

chmod u=rwx,g=rxs,o=rx 556mmfmj

chmod u=rw,g=r,o=r 556mmfmj/*.pk4
