Editor no longer supports Mac OS X 10.11

[Avantir-Chaosfire]

Godot version:
3.3, I think. It's the latest Steam version as of April 26th, 2021. I don't know how to check the version as I can't open the app.

OS/device including version:
Mac OS X 10.11.6

Issue description:
The app crashes instantly on startup when launched from Steam. I launched the app from Terminal and got this:

<Computer Name>:Godot Engine <User Name>$ ./Godot.app/Contents/MacOS/Godot

Trace/BPT trap: 5

It's worth noting that the Steam page lists the minimum requirements as OpenGL 2.1. OS version is not specified.

Thanks for the report, I've fixed the Steam page to specify that it requires macOS 10.12.

The requirement change is expected, it's a consequence of using C++14 standard library in #45618.

Could you check if manually changing the 10.9 versions to 10.12 in /Users/<User Name>/Library/Application Support/Steam/SteamApps/common/Godot Engine/./Godot.app/Contents/Info.plist changes the behavior? E.g. whether it would make macOS give you a friendly error dialog that this version doesn't support your OS, instead of crashing.

I did this:

Which didn't seem to have any effect, when launched via Steam or via Terminal.

Greetings, I am the creator and maintainer of the Godot package for the MacPorts package management system.

I realize that this issue is being reported for Godot Engine on Steam, but I'd just like to point out that on MacPorts, I've been able to get Godot 3.3+ working on old versions of macOS, all the way back to 10.8 (Mountain Lion):

https://ports.macports.org/port/godot/details/

The publicly available package is a couple of patch versions behind, but I already have a MacPorts package prepared for Godot 3.4 that is running, without issues, locally on my macOS 10.11 laptop.

If you really want to run the latest Godot on an old version of macOS, might I suggest giving MacPorts a try?

@Avantir-Chaosfire If you still have access to macOS 10.11, do you get a user-friendly error message when trying to run Godot 3.5.2?

Closing due to lack of response.
