Matching old versions???

Stanford

I have an old mac that I use to remotely access my desktop at home. I upgraded the desktop computer without knowing that the old laptop was running the newest version it was capable of. Now I'm unable to access the desktop from the old laptop. This is the message I get... "Version out-of-date: Update the remote TeamViewer - The remote TeamViewer is running an old version which is out of date. Therefore you cannot connect to this Version anymore. Your connection partner can update TeamViewer by clicking on "Help" - "Check for new version"." Is it possible to downgrade the desktop so that the versions are still the same?

I had similar problems. It appears due to new security features in Teamviewer the computer connecting to the partner needs to be signed in with a Team viewer account and during sign in it will require you to verify by email that the computer connecting to the partner is a trusted device. It took many installs and attempts on multiple computers to figure it out. I am running a 2012 MacBook Pro with Mac OS 10.13 and ended up using Teamviewer 14 for Mac to get it to work. I also established a connection on a M1 Mac running MacOS Ventura with teamviewer 15 connecting to a 2012 MacBook Air on macOS 10.13 and TeamViewer 14.7.2

in both cases I had to be signed in and identify my computer as a trusted device to get teamvier to stop throwing incorrect messages about out of date versions of TeamViewer
