Hello Rachel,
Thank you for your message.
We are currently working on the Viewer for Mac. We hope to release it by the end of the year. Host/Agent for Mac will be released soon after the Viewer. As for the Linux version - since the code base for Linux is almost the same as it's for Mac, there might be a good chance that Linux versions will be released at the same time as Mac versions. Unfortunately, we cannot provide any more specific ETA yet.
Please let us know if you have other questions.
