Because I have another one from ENMVG and its software does not work anymore either. My wife has an iMac but it is 2019 and I am pretty sure it does not have firewire either.Īs far as these cheap capture devices like the Vidbox, it seems like the software is not supported very long by the company that produces them. My Windows 10 PC does not have a firewire card, so I guess one would be needed to try that method.
