Q: I get a bus error when running the external or batch renderer.
A: Update the prebinding of dynamic libraries by running the following command from a terminal:

sudo update_prebinding -root / -force

Q: I've uninstalled turtle and my maya environment variables seems to be broken.

A: All turtle environment variables are added to the file .MacOSX/environment.plist in your home directory. Note that this is a hidden file so you might need some extra work to edit it.

To edit it, open the terminal and type:

open ~/.MacOSX/environment.plist

It should be possible to remove the last traces of Turtle by editing the data in this file.

Q: Turtle crashes when importing a file from maya 6.5 in maya 7.0.

A: The easiest workaround is to rename or delete the 6.5 plugin (/Applications/Turtle3.0/plug-in/TurtleForMaya65.lib). After you've renamed the plugin, you can load the scene again, save it and restore the plugin. The file should now load in maya regardless if the turtle plugin for maya 6.5 is available.
