Urban Terror not launching on OSX 10.9

seta r_ignorehwgamma "1"

You can add that line to your q3config.cfg. To edit it, open a new Finder window, hit cmd+shift+G, and paste ~/Library/Application Support/Quake3/q3ut4/ in the box, and when the folder opens, you'll see q3config.cfg. Just open that file with a text editor like TextEdit. If you don't have that file or folder (perhaps because you were trying to uninstall), open Terminal and enter:

<Full/Path/To/UrT>/Quake3-UrT.app/Contents/MacOS/Quake3-UrT.i386 +seta r_ignorehwgamma "1"

Hit enter and your game will launch with that setting.

So on my computer, that would be

/Applications/UrbanTerror4.2/Quake3-UrT.app/Contents/MacOS/Quake3-UrT.i386 +seta r_ignorehwgamma "1"

This bug apparently has to do with SDL and it seems unlikely that FrozenSand will upgrade their implementation to the newest version.

Setting r_ignorehwgamma "1" will disable in-game gamma/"brightness" controls, so you'll have to manually change it via System Preferences > Displays > Color > Calibrate. Once you create a new "high gamma" color profile, you can just click back and forth between it and your normal settings in the future.

Below is my original (and not very effective) answer...

I always get the deprecated call errors in Console every time I run Urban Terror, in Mavericks and even before Mavericks. It is NOT the source of the problem, nor is it a fatal error.

You CAN run Urban Terror under OS X 10.9 Mavericks. Those deprecated call errors can be ignored (for now at least). Anyone who says different is wrong :)

FIRST, as a potential shortcut, it may simply be a matter of toggling some settings in your config file. This doesn't work for everyone though.

Edit your q3config.cfg file:

On OS X, it's in /Users/~/Library/Application Support/Quake3/q3ut4/q3config.cfg

Open it in a text editor and find the line

seta r_fullscreen "1"

and toggle it off:

seta r_fullscreen "0"

You might also try setting r_mode "-1" and r_customwidth "1280" r_customheight "800"

If that doesn't fix it, follow these steps and hopefully you'll be able to launch the game again:

1. Clean up with Onyx
2. List item
3. Reboot into Recovery mode
4. Repair permissions
5. Repair disk Reboot normally and try to run Urban Terror

So, first you need to clean up your system.

You can do it manually, or automate the process with Onyx. I recommend all Mac users have Onyx installed, but if you don't want to, you can do it all manually. (...you'll have to find your own instructions though! Search for "OS X execute maintenance scripts manually" "OS X rebuild dyld's shared cache" and "OS X cleaning caches.")

Onyx will automate the process. You can get it by searching Google for "Titanium Onyx"

Once you've downloaded Onyx, run it and open the Automation tab. Check the following boxes:

This will close all running apps and it may take about 20 minutes or so to complete. When it's done, you will have to restart your computer. BEFORE you hit execute:

Save the following instructions somewhere if you can't remember them: After Onyx runs and you reboot, boot into Recovery mode by holding command+R. Once Recovery mode boots, open Disk Utility. Select your hard drive in the list and click the "Repair Permissions" button. Once that runs, click the "Repair disk" button. When that finishes, reboot and see if Urban Terror will run.

Okay, now that you have all the instructions, hit Execute in Onyx and start the process.

I took all of these steps at the same time, I still don't know exactly what the cause is, but my theory is that there is some cached data in the GL driver cache that is messing with the game. Once you clean the system/user caches, you should be good... but may as well do a full cleanup and repair permissions and the disk in Recovery mode, just to be sure.
