I use two iMacs from 2007, with Mac OS X 10.11. I have installed versions 5.6.1 from the Apple Mac App Store. Today the updates to the versions 6.0 are available to me but only when reading that it was not compatible with systems previous to 10.12 I have not followed.
Going to the page of the applications, they keep appearing as compatible with 10.9, although in the description in the section of the new it is again indicated that they are not compatible with anything before 10.12
I visit then the web of bruji, and they already warn of the requirements of 10.12 for all versions 6.0. To check I have downloaded the demos, and I see the sign of prohibited in all of them.
If so, why does MAS offer me the update if it is not compatible with the installed system?
I love that they offer the new version for free to old users, of course. But it should only be installed if it is really compatible.
Greetins,
