1 Since you are reading this, OpenTTD have crashed. This file tells you how 

     2 to fix the most common problems or make to make a bug report, that the 

     3 developers can use to track down the problem

     4 

     5 If it is an assert, OpenTTD will open the console for you, if it is truly a crash, you have to do it yourself. The Console is located at /Applications/Utilities/Console.

     6 The problem is near the button of the page

     7 

     8 The problems are as follows:

     9 NOTE: build from source means to download the source and compile 

    10 yourself. If you get one of the build from source error with the version 

    11 that is downloaded on a dmg file, you should make a bug report

    12 

    13 --Didn't find a needed file:

    14 	you just give it the file it asks for. It even tells you what 

    15 folder it wants it in

    16 	most common version of this problem is "Error: Cannot open file 

    17 'data/sample.cat'"

    18 	if you get that one, that means that you haven't got all the 

    19 needed files from the WINDOWS version of TTD

    20 	or if you build from source, 

    21 

    22 --Error: No available language packs

    23 	you need at least one .lng file in your lang folder. This applies 

    24 only to people who build from source

    25 

    26 --spritecache.c:237: failed assertion `b'

    27 	you got an outdated grf file. Update from the data folder in the 

    28 source. This applies only to people, who build from 	source

    29 

    30 --assertion error that are not triggered by one of the errors listed in 

    31 this file:

    32 	you most likely found a bug. Write down the assertion and try to 

    33 see if you can reproduce it. If you can, make a

    34 	savegame from just before it happens (autosaves are useful here) 

    35 and post a bugreport with it on sourceforge

    36 	Write what you did to trigger the bug and what assertion it made
