Hi Bryan and Stuart,
Thank you for your answers to my questions!
In terms of other M2 Mac's, does anyone know if the Macbook Air M2 13"
uses a supported WiFi chipset ?
Some sources online[0] suggest that the chipset is: BCM4387. Based on
the OpenBSD FAQ and: man bwfm this is a supported chipset, but I was
wondering if anyone had any real world experience with it ?
Related to this .. I noticed the following at the bottom of man:
"The firmware is outdated and contains known vulnerabilities."
Does that apply for newer chipsets like the BCM4387 ?
Thanks again,
- J
