@phush0 which one is failing? en8?
@FASHION399 please try the new version.
yep en8, I tried and Dell one on en9 with same fail result
still trying to get it, what's the difference between this simple action that worked couple days ago for me:
- disconnect from wifi network (do not turn off wifi adapter)
openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx- connect back to local wlan
and this script???? o_0
the main difference I see is in openssl generator (syntax is a little bit different)
This is the only script that worked for me on MacStudio Wifi / Sonoma. I will try on Macbook Pro.
Thanks a lot and please keep it alive.
Thanks this is working great for en0 wi-fi!
This script doesn't work for some people because when it runs "sudo ifconfig $adapter up", it auto-associates with a known SSID if a known SSID is found. The wifi adapter needs to be on and not associated for it to work. That's why the following step works, "disconnect from wifi network (do not turn off wifi adapter)".
It's not woking on MACOS sonoma 14.4.1 (23E224), MacBook Air, Apple M1.
It showed the error message: "ifconfig: ioctl (SIOCAIFADDR): Can't assign requested address"

I don’t quite follow. Can you explain what you mean?

What is the interface of your Wi-Fi adapter?
Attached the screenshots:
Looks like Apple killed this in Sonoma. There may be no practical workaround. If I find one, I'll update.
well script is working only with original adapter from Apple. If I try to change mac on the dock adapter it is not working. So it sounds like Apple fault.
