这里不推荐使用源码安装的方法，太麻烦。要想brew安装快一些，只要让命令行走一下代理就行。
Mac下用Homebrew安装的，配置文件默认路径为/usr/local/etc/proxychains.conf
➜ ~ cat /usr/local/etc/proxychains.conf
# proxychains.conf VER 4.x
#
# HTTP, SOCKS4a, SOCKS5 tunneling proxifier with DNS.
# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
#dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#round_robin_chain
#
# Round Robin - Each connection will be done via chained proxies
# of chain_len length
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped).
# the start of the current proxy chain is the proxy after the last
# proxy in the previously invoked proxy chain.
# if the end of the proxy chain is reached while looking for proxies
# start at the beginning again.
# otherwise EINTR is returned to the app
# These semantics are not guaranteed in a multithreaded environment.
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see chain_len) from the list.
# this option is good to test your IDS :)
# Make sense only if random_chain or round_robin_chain
#chain_len = 2
# Quiet mode (no output from library)
#quiet_mode
# Proxy DNS requests - no leak for DNS data
proxy_dns
# set the class A subnet number to use for the internal remote DNS mapping
# we use the reserved 224.x.x.x range by default,
# if the proxified app does a DNS request, we will return an IP from that range.
# on further accesses to this ip we will send the saved DNS name to the proxy.
# in case some control-freak app checks the returned ip, and denies to
# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
# of course you should make sure that the proxified app does not need
# *real* access to this subnet.
# i.e. dont use the same subnet then in the localnet section
#remote_dns_subnet 127
#remote_dns_subnet 10
remote_dns_subnet 224
# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000
### Examples for localnet exclusion
## localnet ranges will *not* use a proxy to connect.
## Exclude connections to 192.168.1.0/24 with port 80
# localnet 192.168.1.0:80/255.255.255.0
## Exclude connections to 192.168.100.0/24
# localnet 192.168.100.0/255.255.255.0
## Exclude connections to ANYwhere with port 80
# localnet 0.0.0.0:80/0.0.0.0
## RFC5735 Loopback address range
## if you enable this, you have to make sure remote_dns_subnet is not 127
## you'll need to enable it if you want to use an application that
## connects to localhost.
# localnet 127.0.0.0/255.0.0.0
## RFC1918 Private Address Ranges
# localnet 10.0.0.0/255.0.0.0
# localnet 172.16.0.0/255.240.0.0
# localnet 192.168.0.0/255.255.0.0
# ProxyList format
# type ip port [user pass]
# (values separated by 'tab' or 'blank')
#
# only numeric ipv4 addresses are valid
#
#
# Examples:
#
# socks5 192.168.67.78 1080 lamer secret
# http 192.168.89.3 8080 justu hidden
# socks4 192.168.1.49 1080
# http 192.168.39.93 8080
#
#
# proxy types: http, socks4, socks5
# ( auth types supported: "basic"-http "user/pass"-socks )
#
[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
# socks4 127.0.0.1 9050
socks5 127.0.0.1 1086
➜ ~
默认的socks4 127.0.0.1 9050是tor代理，可以直接注释掉。
在最后一行添加本机的代理地址127.0.0.1 1086
然后使用proxychains4命令看看管没管用：
➜ ~ proxychains4 curl cip.cc
[proxychains] config file found: /usr/local/etc/proxychains.conf
[proxychains] preloading /usr/local/Cellar/proxychains-ng/4.14/lib/libproxychains4.dylib

发现没有任何用，为啥呢？因为我用的是万恶的Mac。
macOS 10.11 后下由于开启了 SIP（System Integrity Protection） 会导致命令行下 proxychains-ng 代理的模式失效，如果使用 proxychains-ng 这种简单的方法，就需要先关闭 SIP。
关闭 SIP
重启Mac，按住⌘ + R进入Recovery模式。 实用工具（Utilities）-> 终端（Terminal）。 输入命令csrutil disable运行。 重启进入系统后，终端里输入 csrutil status，结果中如果有 System Integrity Protection status:disabled. 则说明关闭成功。
➜ ~ csrutil status
System Integrity Protection status: disabled.

我们再试一次：
➜ ~ proxychains4 curl cip.cc
[proxychains] config file found: /usr/local/etc/proxychains.conf
