AusMap replaces QGIS -> Preferences menu item on macOS

[miceg]

On macOS, QGIS has two menu items which open the options dialog:

• Settings -> Options (the same as QGIS on other platforms)
• QGIS (application menu) -> Preferences (following macOS conventions)

When running QGIS without the AusMap plugin installed (or enabled):

• Selecting either menu item opens the QGIS settings
• Both menu items have a spanner icon
• Pressing Command + , opens the QGIS settings (macOS convention)

When you install and enable the AusMap plugin:

• QGIS (application menu) -> Preferences opens AusMap's settings, and has a cogwheel icon
• Settings menu -> Options still opens the QGIS settings, and still has a spanner icon
• Pressing Command + , opens AusMap's settings

I also notice that the "AusMap" menu doesn't contain the Settings or About this plugin entries like it does on Windows – all the layers are otherwise there.

It's hard to tell what's going on because the version published to the QGIS plugin repository differs from what's here on GitHub.

Affected versions:

• QGIS: 3.36.3-Maidenhead, 3.38.0-Grenoble (tested with both versions on macOS)
• AusMap: 1.1
