Thatâll do it
Did you edit Makefile.platform?
If not you need to copy Makefile.platform.sample to Makefile.platform and use your favorite text editor to comment out PLATFORM=PM3RDV4 un-comment #PLATFORM=PM3GENERIC
Or, you can install gsed:
brew install gnu-sed
and then run these commands inside the PM3 directory:
cp Makefile.platform.sample Makefile.platform
gsed -i '0,/PLATFORM=PM3RDV4/{s/PLATFORM=PM3RDV4/#PLATFORM=PM3RDV4/}' Makefile.platform
gsed -i '0,/#PLATFORM=PM3GENERIC/{s/#PLATFORM=PM3GENERIC/PLATFORM=PM3GENERIC/}' Makefile.platform
And then youâll need to re-flash your PM3 with the pm3-flash-all script

Oh right thanks.
I canât find makefile. Iâve found the hidden folders .\usr\local\cellar\proxmark3 with a whole stack of folders and files but no Makefile.
Could I go back and reinstall Proxmark with brew install --with-generic proxmark3?

I think thatâs done the trick. This is what it tells me when i run PM3 now:
