Introducing MSP360™ Remote Assistant for macOS
With all due respect - to advertise the macOS version on MacUpdate.com
as "a freeware tool that enables quick and secure connections to remote systems, making it easy for MSPs to provide support over the internet" seems to be a rather bad joke at this time.
This application can not be used to establish any connection to another computer to "provide support" (control that computer). Whether it can be used to GET support (from a Windows machine only) I don't know, but this is anyway not how it is being presented.
How about you try again in half a year (or whenever this thing works)? In the meantime I suggest to change the description so that it is clear what this is about right now.
