I don't dare try it, we have business and are at about 2.2 TB online and it has been painful with the client crashing. We have to limit the number of synced driectories or it crashes. typically the current released client uses a peak of about 1.8 GB, then after a while it crashes and keeps crashing... so we have to reboot... really painful for a business product that costs $$ each month per user.
Since I read the horror stories about uninstalling the beta, but then the registry leftovers won't let you load anything but another beta, no way I am trying this....
we need better software, and faster fixes, after all, the fundamental engine (client) is unstable, fix that first! no more new features
it looks like Dropbox will not work under MacOS 11 (Big Sur) and this installer crashes quietly when trying to reinstall. This is a developer release of Big Sur and it's first release but Dropbox is pretty important. Hopefully this will be figured out soon.
