Require macOS Catalina or later #4837
Description
What you want IINA to do:
Require the Mac to be running macOS Catalina (version 10.15) or later.
What IINA does currently:
IINA is currently documented as requiring the Mac to be running OS X El Capitan (version 10.11) or later. As discussed in issue #4634, IINA 1.3.2 through 1.3.4 actually require macOS High Sierra (version 10.13) or later. See that issue for further discussion regarding support for OS X El Capitan and macOS Sierra.
Why you think this should be added:
IINA is built on top of source code (libraries and frameworks) from other projects. This code can be seen if you look inside the IINA application:

This means that IINA can only support the macOS versions supported by all of the code obtained from other projects.
For audio/video and subtitle rendering support IINA uses a library from the mpv project. This is IINA's primary dependency.
From the System requirements section of mpv's README:
A not too ancient Linux (usually, only the latest releases of distributions are actively supported), Windows 10 or later, or macOS 10.15 or later.
The mpv project has raised their minimum supported macOS version to macOS Catalina. Code that supported older versions of macOS has been removed from the source code.
IINA has no choice but to also raise its minimum supported macOS version to match. 😞
