I have downloaded OTTD for MAC OSX and it works. But now I want to install some Grf files... and they work not.
What I did:
After installation and testing I downloaded the DOS grf. files like dbset and cargoset.grf.
I made a new map named Newgrf and placed them into this map.
Opened OTTD and I couldn't load the new GRF files. So I closed the program and opened the openttd.cfg file.
Here I typed (under in the box [newgrf]) dbset.grf and safed the file.
Opened ottd again but couldn't load the file either.
Then I went back to the openttd.cfg file, but found that my changes were gone. (so what I placed under newgrf was not there anymore).
Can someone please tell me how to get it working so I can really drom my Windows PC from the balcony.

Kind regards,
A happy Mac user.... well..... almost hapy
