Teamviewer is the popular choice for remote access software right now, with many home and businesses depending on it running smoothly at all times to help manage day to day matters.

  1. I can establish a PC to MAC connection (and visa versa), but MacBook Air to Macbook Pro (and visa versa) triggers the 'Version out of date/Reason unknown' sequence of errors. Does not seem to be TV version specific. MAC OS version is High Sierra 10.13.6 on both machines. TeamViewer version are the same on the MACs - 12.0.139437.
  2. If you have heavy usage, connect to any computers on a business network or business internet connection or from a business network or business internet connection/Server OS/VPN/Virtual Machines, or a licensed version of the software on either network, it will detect that and pop up Commercial Use Suspected (or one of their other detection and message types).
  3. I know this issue has been reported earlier, and I have searched other posts, but that still didn't solve my problem. I am using the free - 108188.
