Aleuran

I have recently purchased the Avernum trilogy on steam. Escape from the Pit synchronized files to steam cloud from my pc desktop and was available on my mac laptop. I started playing Avernum 2. The option for cloud saves is selected and it shows files in the cloud on my pc but does not show on my mac. I also tested this with A3 and files did not show up on the mac. I opened a ticket with Steam support and they said to check on these forums. Has anyone had luck getting this to work in A2 or A3? Thanks
