Thanks Ying for your reply and the links. I'm still confused though. My friend's iMac is from around 2005 and it's running Yosemite, as I wrote. And, I have a 2008 Mac Pro also running Yosemite. Both Macs have the same free version 12 of Teamviewer. Should I be able to connect and control my friend's iMac? I understand that TeamViewer no longer provide support, but I'm only trying to help a friend with some simple stuff. If the above will not work, can you suggest a workaround? Thanks!

I was trying to manage a friend's iMac using Teamviewer but kept getting a message saying her version was too old. My iMac is Catalina but my friend's iMac is running OS X Yosemite, 10.10.5 (I think). Then I tried from an old Mac running OS X Yosemite and got the same message. I discovered my Yosemite Mac was running Teamviewer 12 (I think - cant' check right now) and my friends was on version 10. I helped her download version 12 and install it on her iMac. We were both on the same OS X and using the exact same version of Teamviewer. But I got the same 'too old' version error message and still could not connect. Originally I was trying to access her iMac from my iMac running MacOS Catalina 10.15.4. I got that 'too old' message and gave up. I had been able to connect to my friends iMac using Teamviewer the last time I tried about a year or so ago, but before I upgraded to Catalina. So I've no idea what the problem is. Can anyone help? Thanks!
