brew install privoxy

2. copy and modify config file

# x86
cp /usr/local/etc/privoxy/config /usr/local/opt/privoxy/sbin/
# arm64
cp /opt/homebrew/etc/privoxy/config /opt/homebrew/opt/privoxy/sbin/

# add the following line into config file, it means forward filtered data to Tor.
forward-socks4a / 127.0.0.1:9050 .

3. launch

# x86
./usr/local/opt/tor/sbin/tor
./usr/local/opt/privoxy/sbin/privoxy
# arm64
./opt/homebrew/opt/tor/sbin/tor
./opt/homebrew/opt/privoxy/sbin/privoxy

4. check if listen

netstat -an | grep 9050
127.0.0.1:9050 LISTEN

netstat -an | grep 8118
127.0.0.1:8118 LISTEN

Manually set your proxy configuration, fill HTTP and SSL Proxy column up with "127.0.0.1:8118".

Ref: Use both Tor and Privoxy

Agree with @Zettt
I Followed followed commands
brew install tor
brew install privoxy
cp /usr/local/etc/privoxy/config /usr/local/opt/privoxy/sbin/

open /usr/local/opt/privoxy/sbin/config
add this following line into config file in the end, it means forward filtered data to Tor.
forward-socks4a / 127.0.0.1:9050 .

cp /usr/local/opt/privoxy/sbin/config $HOME
open /usr/local/opt/tor/bin/tor
open /usr/local/opt/privoxy/sbin/privoxy

I'm also wondering where to place the forward-socks4a / 127.0.0.1:9050

You uncomment the line you don't need to add a line

To modify the steps for your Apple Silicon Mac, it needs some path changes, i.e. use /opt/homebrew rather than /usr/local.
