Hello,

My Issue with TOS6:
I brought it for Sync on Demand feature only to find out Mac is not supported (I also cannot see anywhere about TOS7 bringing the feature)

I am upgrading from a 4 bay DSM 918+ to a 6 bay F6-424 Max and the specs on the Terramaster for the money were so much better I really got use to Synology Drive Client where I could see my files and choose on the fly to pin and free up items only to present with the same feature set from TerrasSync only to miss the "On Demand Sync is for Windows only" note

I would assume the install would also work for the F6-424Max as well but from the option of selecting a DSM the DS925+ doesn't really match my box

Would I just need to select a different model and if so what is the best related selection from the menu of DSM choices.. if I just select the DS925+ like you did will it only see 4 of the bays and not 6 then?

Thanks for any help / Support (Since I know it doesn't directly apply to this Guide, but this was the best thread I found)
