@jonpontet I am going to try this

to see if it will automatically run the command on reboot, which does not really address the problem, but will save some time

@jonpontet the above worked for me. In step #4 and #8 you must replace "xed" by "gedit" . I replaced "5" by "10" in step #5. Hope it works for you.

I got the same procedure to work for Kali Linux 2023.3 on a late 2013 MBP. The only difference is the adapter designation in Kali is simply wlan0. However, the procedure is solid and worked on the first attempt. Thanks for posting this!

Thanks, this worked great!
