you should be fine to just run it.
I get this:
Error: invalid option: --without-readline
try
brew install --build-from-source proxmark3 --env=std \
GENERIC=1 DISABLE_READLINE=1
i havent used brew for PM3 in a long time, i reccomend downloading from Git and building from source usually.
Now I get a different error:
Error: Calling brew install --env is disabled! Use env :std
in specific formula files instead.
I will look for the instructions on how to build from source and try that way
I got it to work, thank you all for the patience!
share how (for future generations who might come along)
Sure. I built it from source as recommended by Hamspiced, making sure to include the arguments shared by sunilm adapted for the PM3 GENERIC:
git clone GitHub - RfidResearchGroup/proxmark3: Iceman Fork - Proxmark3
cd proxmark3
git pull
make clean
make all PLATFORM=PM3GENERIC SKIPREADLINE=1
./client/proxmark3 -p /dev/tty.usbmodemiceman1
Not sure if all the steps where actually needed (I dont have experience in this, just following guides ), but now it works.
I had the same issue while using iTerm2. Using the Homebrew version fixed it for me.
