The macOS build of Feedback Emulator was meant to ship this month. It is now planned for September.
The build itself is not the hold-up. Shipping a signed and notarised macOS plugin means the Apple developer account has to sit under a registered company, and getting the company set up and the account tied to it is taking longer than expected. Until that is done we cannot notarise, and an unnotarised plugin is not something we want to hand anyone.
Nothing changes about the plugin: it stays free, and the Windows version is unaffected. We will post here as soon as there is a date.
