Is running the 64-bit VM now unsupported on anything less than macOS
(nee OS X) 10.13 or 10.14? Perhaps because of the Metal changes and
I just compiled the 64-bit VM fresh and tried running it on my
10.12.6 system. I got a Squeak window with no graphics inside (just
blackness) and a message on my terminal console:
2019-03-21 10:58:55.324 Squeak[70669:4778174] Pipeline state creation
error: Function screenQuadFragmentShader is using language version 2.1
which is incompatible with this OS.
If so, I may need to make a choice between:
- upgrading my operating system,
- using the 32-bit VM (though my image is 64-bit),
- staying on an older VM version (though I leave it running for many
days and its memory usage balloons from ~313 megabytes to multiple
gigabytes, perhaps due to the event handling memory leak bug, which I
was hoping to leave behind).
I wonder if it would be worth the effort to handle this situation
gracefully rather than bringing up a non-functioning environment which
requires a force-quit. Perhaps this could be easily accomplished by
including the proper minimum OS version in the Info.plist of the 64-bit
app bundle and letting macOS do the work of disallowing a launch on
older OS versions.
