I have a problem that seems to be common with the installation process of the nRF52840 on Mac Monterey 12.4.
When I run:
brew update brew install ./etc/wpantund.rb
Warning: No available formula with the name "wpantund". ==> Searching for similarly named formulae... Error: No similarly named formulae found. ==> Searching for a previously deleted formula (in the last month)... Error: No previously deleted formula found. ==> Searching taps on GitHub... Error: No formulae found in taps.
I tried to uninstall and re-install several times brew. And Brew doctor seems to be fine.
Have you got solutions for that purpose?
