Unable to load Preferences LC 9.6.9rc3 and Levure 9.0.5

[Marty Knapp]

I don’t have an “M” chip Mac here to test at the moment but here’s something to try:

In the Levure framework open the helpers folder and then the preferences folder
Modify the helper.yml file by deleting the section under externals so the file just contains the following

externals:
libraries:
  - filename: preferences.livecodescript
extensions:
  - filename: nsuserdefaults.lcm
    engine version: ">=9.0"
    platform: macos,ios

Then try a build and see how that works. I just tried it on my Intel iMac and preferences are working OK without the previous content.

Please let me know how it works on your “M” mac
