Love gocryptfs but it doesn't work well on Mac. securefs[1] works fine on both Linux & Mac.

do you know what advantages that has over rclone[1], which is much more popular?

I guess both securefs & gocryptfs are more tailored towards mounting encrypted folders locally (i.e. they don't have any support at all for cloud storage systems, that part is left to other tools).

But I guess you can do the same with rclone given that it supports encryption, mounting and the local filesystem.

I am not sure however how they compare in simultaneous read/write access by multiple users.
