Problem of not being able to save work on macOS 10.11 series

[Gasparoken]

In the last month, we received 3 support tickets with problem of not being able to save work on macOS 10.11 series.

Possible issue on native "Save As" menu.

Console message trying to Save As:

An unknown error occurred executing the command. Please save your work, close the program, try it again, and report this bug.

Details: unknown exception caught. This can be bad memory access, division by zero, etc.

Probably a release blocker (i.e. we cannot release v1.3 with this bug), I'll try to get a macOS 10.11.3 (I think I have an old Macbook with 10.11, but I'm not sure)

I tried to create a macOS VM on Parallels Desktop with El Capitan (10.11), but basically it's impossible to find an image to install this old OS.

I'll try to test this in a pretty old MacBook 2012. Anyway the solution might be just disable the native file selector in OS X 10.x series (and enable only since 11.x)

Tested in my old MacBook (OS X 10.13) and it worked:

We've disable the native file selector for 10.11 or older versions.
