Install proxychains-ng on macOS m1/m2 arm64e natively without Rosetta 2 (2023)

proxychains-ng_m1.txt

Problem:

```bash
brew install proxychains-ng 
proxychains4 ncat 1.2.3.4 # not working
```

There are public workarounds like https://benobi.one/posts/running_brew_on_m1_for_x86/ 
which suggests to use brew's x86_64 version or run the proxychains4 binary with `arch -x86_64`.
This seems to be working, but it hurts performance (with Rosetta 2 emulator). 

Here we can find the proxychains4 binary, in which, it runs natively on our beloved M1/M2 chips <3

Solution:
# M1/M2 supports arm64e, but we need to enable it.
# https://developer.apple.com/documentation/driverkit/debugging_and_testing_system_extensions#3626024
# Tested on macOS 13.2.1 (2023)

# shutdown & long press Power button to recovery mode -> Terminal
csrutil disable
# reboot to normal mode
# enable arm64e support
sudo nvram boot-args=-arm64e_preview_abi
# reboot
Then,

```bash
git clone https://github.com/rofl0r/proxychains-ng 
cd proxychains-ng 
CFLAGS="-arch arm64e" LDFLAGS="-arch arm64e" ./configure --prefix=/usr/local --bindir=/usr/local/bin --libdir=/usr/local/lib --fat-binary-m1
make

$ file ./proxychains4

can any one compile a m1 version for every one to download that?

@sorryyyy Your process is being killed because SIP (csrutil) is enabled, and there is no way to bypass this. A binary built under arm64e will work ONLY with SIP disabled.

In your instructions, you replace the proxychain4 built for arm64e with one for arm64, which makes all the effort pointless (the same arm64 binary can simply be installed via brew).

As for me, I just decided not to proxy binaries provided by the system (for example, ssh) but to install them through brew. This way, they are properly proxied through proxychains from brew.
