I am a huge fan of Smart Sync and being able to have Online-Only files. I have been using it on Mac OSx for some time now. But I have been reading that from OS Catalina, Apple is deprecating Kernal Extentions (Kexts) which I suppose is what Dropbox uses to support Smart Sync. Will Dropbox be able to support Smart Sync in future versions of Mac OSx now that Kexts are done? What will they use instead to support these feature. I'm just a bit worried that I will have to start keeping a download of all my files locally, which is going to take up massive amounts of space of my computer.
