[Interest] [Development] Qt 6.5 Is Irrelevant for More than 95% of Mac Desktops

[Michael Jackson]

I agree here. Is Qt 6.5 now using an API or a compiler feature that macOS 10.15 does not support? If that is the case then sure I agree with the change. If you are changing "just to change" then I don't really agree. I sort of get the argument that "Apple stopped supporting 10.15" but what implications does that have for Qt 6? Is there a security library that Qt 6 depends on (OpenSSL is my guess) that 10.15 isn't now updating? Is Qt 6 using the new APIs from that version of OpenSSL (or what ever library broke)? Is there a graphics API that Qt 6 now depends on that is macOS 11.0 and greater? Maybe that is the reason?

    Hello,

    It's understandable why Apple did this.

    But why did you do this? Does the supporting of 10.15 really increase 
    the development cost for Qt Company?
