I have desperately wanted to respond to this thread, but due to an IP address, I have been unable (until now) to use this site. I even tried emailing eddeduck directly, but to no avail. Here's my problem:
I installed tattiebogle driver v. 0.09, and although the Xbox controller IS recognized by my iMac, it is NOT recognized by Bioshock. I read where some users have better luck with v. 0.08, but I am unable to install the older driver over the newer one, and I have no idea how to uninstall v. 0.09 so I can install v. 0.08 (I have tried removing all references to the driver, but there must be some artifacts remaining because I still get the error message when I try to install v. 0.08). Any help will be GREATLY appreciated!
