Update bridges to make tor service work on MacOS

bridges-tor-mac.md

Install tor via HomeBrew and start the tor service.

brew install tor && brew services start tor

And to use obsf4 proxy we need to install its library/ Use HomeBrew for installation of the library.

brew install obfs4proxy

https://formulae.brew.sh/formula/obfs4proxy

Get the obsf4 bridges from https://bridges.torproject.org/options or send email to [email protected] with body get transport obfs4.

Create if not exists and edit the torrc file ($(brew --prefix)/etc/tor/torrc), add the following

# Using Bridges, obsf4
UseBridges 1
ClientTransportPlugin obfs4 exec /opt/homebrew/bin/obfs4proxy managed

# send email to [email protected] with body `get transport obfs4` you can get new bridges.
# Or use https://bridges.torproject.org/options
# Paste the obsf4 bridges here and put Bridge in front of each.
Bridge obfs4 78.194.206.56.. B80190D0C0771298F04AE56L..... cert=61xl3nF07Ssg... iat-mode=0
Bridge obfs4 185.220.101.17.. 59F4CBDE79D51FEC12AC1F4304D006C97D4.. cert=p9L6... iat-mode=0
Bridge obfs4 185.220.101.17.. 59F4CBDE79D51FEC12AC1F4304D006C97D4.. cert=p9L6... iat-mode=2

Now restart the TOR service using

brew services restart tor

Check Ip addresses are different with and without proxy.

ip_no_proxy=$(curl -s https://api.ipify.org)
ip_with_proxy=$(curl -s --proxy socks5h://127.0.0.1:9050 https://api.ipify.org)
if [ "$ip_no_proxy" != "$ip_with_proxy" ]; then
    echo "IP address is different with and without proxy."
    echo "IP without proxy: $ip_no_proxy"
    echo "IP with proxy: $ip_with_proxy"
else
    echo "IP address is the same with and without proxy."
    echo "IP: $ip_no_proxy"
fi

To change the circuit run

brew services reload tor
