Bugs need to be fixed
It’s not cheap so it should be 100% working but I found two bugs that are annoying.
First bug is that you can only use default folder (Downloads), if you select any other folder for transfered files and then restart your Mac, you get info that folder was changed back to Downloads because there is an issue with folder you chosen.
Another problem is transfering many files. If you choose more than couple files, transfer is hanging and all you can do is to cancel transfer and choose less files.
