I need to fix my sister's macbook remotely. She is not very computer literate so I wanted to do a dry run here. A: Your download page does NOT tell you that downloading version 15 won't install on an older mac. (Machines concerned are running 10.10.4 TV 15 requires OS-X 10.13.) This is a bug. B: If I try using "Check for Updates" from within my older version of TV, it ALSO will try to download version 15. This is a bug. C: If I search the Downloads page for older versions, YOU DONT SAY WHICH WILL WORK ON WHICH OS's. This is bad website design. D: Nowhere on your website can I find anything that details the tradeoffs of mis-matched versions -- whether they interoperate at all. At one point you had a version of TV that didn't have to be installed. You could run it off a thumb drive. Is this still available? How do I find out which version of TV a given OS will accept? Are all versions of TV interoperable? Are there performance penalties for using differing versions?
