Project mention: Apple II Emulation Evaluation (2022) | news.ycombinator.com | 2024-01-02

Check out Mariani, a port of AppleWin (Windows) for macOS and Linux. It's open-source, cycle accurate and emulates a fairly good number of devices: https://github.com/sh95014/AppleWin
The last version finally has a debugger. It lacks the killer feature of Virtual II though: the ability to mount a folder. This is gold for cross development.
