macchanger -r freezes

[hexdump]

when i try to randomize my MAC address, macchanger seems to freeze. after running $ macchanger -r en0 and waiting for about ~30 seconds, no output is shown; hitting ^C stops the program, giving the following error:

^C/usr/local/bin/macchanger:56:in `system': Interrupt
	from /usr/local/bin/macchanger:56:in `set'
	from /usr/local/bin/macchanger:48:in `random'

i'm running macchanger 1.3.2 on macOS 10.14.6 (18G3005). i installed by running brew install acrogenesis/macchanger/macchanger.

Hello @hexdump I've tried replicating this problem in 10.15.2 but it worked well.
Are you getting asked for your password? Is your en0 device turned on?

[hexdump]

ok, this is getting weird. i wasn't asked for my password yesterday and the day before, but i am getting asked for my password today. my en0 device is turned on, and i can set its address manually with -m/--mac.

[acrogenesis]

So it's working now?

[hexdump]

no—still freezes.

For me the problem was caused by inetutils that change the ifconfig path, in fact when macchanger call for ifconfig it is not in che /sbin/ifconfig but in a subdirectory of inetutils
if you do
which ifconfig
and it's inside a path like /usr/local/opt/inetutils/libexec/gnubin/ifconfig this is the error

I try to down my interface with
sudo ifconfig en0 down
and not work, but with
sudo /sbin/ifconfig en0 down
it worked

Thanks @leomiglio02 I've changed the default to /sbin/ifconfig 30c657b
