Frequently Asked Questions
Is this driver free?
Yes, Callisto (project name) is free but consider donating a few $ for my efforts, I have spent many days and nights on this project so that everyone could have a fully working graphics display in OS X x86.
What about the source code to Callisto?
I will not be releasing the source code, binary is sufficient.
Which versions of OS X are supported by Callisto?
I have ran it in 10.4.4, 10.4.5, 10.4.6. The binary is compiled with the universal SDK on a 10.4.6
My graphics card is not detected when Callisto loads!
Callisto is work in progress and it is likely that not every card/chip is supported or could be supported, try again later or get a card that is known to work.
Tell me about ATI cards and monitors that work with Callisto?
Check the User Testimonies page for user experiences and their feedback.
The driver crashes during the boot.
Did you read this F.A.Q. and the Installation instructions, and followed them exactly? NO, REALLY, DID YOU READ THEM AND DONE EXACTLY AS I SAID? I know it's exciting to get a fully working system but that can't happen if you don't follow the instructions...
My system does not boot anymore after installing Callisto.
Sorry to hear that but I can't help you there. You knew what the risks were prior to installing it. Try reading the rest of this F.A.Q. as well as the Troubleshooting page for possible help on resolving your problem.
I used to be able to autologin and now I get a login prompt?
It has been reported that this can be corrected by replacing IOPCIFamily.kext with an older one.
See this forum posting for details and link.
How come Callisto doesn't have: Dual display support, TV out, Video In/Out, Theatre support, or any other extra ATI feature?
Scope of this project is to provide a driver and framebuffer so that ATI users can change resolutions and refresh rates in OS X x86. All the other options of the card are not part of this project and if they ever happen to be added, then consider it a bonus. If they are not added then nothing is lost.
Does Callisto provide 2D/3D acceleration?
No, this is a low-level driver and framebuffer, acceleration is provided by IOAcceleration class, use existing Apple KEXTs (ATIRadeon*.plugin/bundle) for that.
How do I get the QE/CI/OpenGL KEXTs to work with Callisto?
Look in your /System/Library/Extensions folder for ATIRadeonXXXXGA.plugin/ (XXXX depends on your card model).
Edit its Info.plist, under IOProviderClass key change IONDRVFramebuffer to CallistoFB, update or delete
Extensions.mkext and Extensions.kextcache, then reboot.
I can't play any games!
