As everyone else on Leopard (Mac OS X 10.5.8) I can’t play the game due to crashes. However I haven’t seen anyone mention it crashes on loading as well. Oddly enough, the crash report is different. So for your debugging pleasure here it comes. First, the Mac OS X problem report: dredmor1.log. (Couldn’t include it here because of the message length limit on this forum. It’s over 20000 characters by itself.) Second, the abbreviated debug trace: Code: creating a Gem Segmentation fault Here is the full trace, but everything before the above 2 lines shows up while loading the main menu and doesn’t seem to effect the crash: Code: Martijns-MacBook:MacOS martijn$ ./dredmor -debug-flag [S_API FAIL] SteamAPI_Init() failed; no appID found. Either launch the game from Steam, or put the file steam_appid.txt containing the correct appID in your game folder.
