OTOY Forums

Hi. I just finished building egpu unit on 980ti and akitio. I installed it on imac 5K using a script (gpu automation install) and no i have it visible in system raport but when i launch Octane it shows no cuda cores and no cards. Is it a drivers issue or wrong instalation? I use imac 5k running Sierra.

Hi paweł.kaczorowski,
unfortunately, is not Octane only.
Mac Os Sierra is too new and it seems to have issues with Maxwell GPU and any CUDA appications at the moment, even with Nvidia web drivers:

We have to wait for an update, I guess.
