Important: the 64 bit version can only be used (in opposite to the 32 bit version) with macOS 10.10 or newer on Intel computers.
This version does not use "QuickTime" anymore but "AV Foundation" instead, because Apple deprecated QuickTime for 64 bit applications.
Some facts must be noticed therefore:
The 64 Bit version is compatible to Gatekeeper, signed by an identified developer and notarized by Apple.
Thru buying a nessMediaCenter licence the version will be a full version - otherwise the version will be a demo version.
