# Legacy AMD
So what's this section for? Well, a decent chunk of users have been wondering what the highest supported OS would be for their GPU if the latest isn't supported. The GPUs listed have theoretical support but keep in mind that they're not guaranteed to work unless shipped in a Mac Pro (opens new window). Also keep in mind that this list will likely change as research is done on what device IDs are supported.
Also to note: InjectATI may be required for these GPUs.
