FOVE's public software release has supported Windows from the beginning. (Currently 8.1 and later).
Linux is supported as of October 2020 (v1.0). It required Ubuntu 20.04 & NVIDIA. Please see our detailed article: https://support.getfove.com/hc/en-us/articles/900003198366
Internally, we have Mac builds, but the lack of direct mode support prevent it from running well at the current time. Also, recent macs do not have HDMI ports so we will have test adapters to find one that works.
If you need a Mac build, or a Linux configuration not support please contact the support portal, and we may be able to work with you to get you a custom software release that suits your needs. This depends highly on how much work it is, but we are also open to contracts for custom support.
