generally it doesn't work.

why does your proxychains not print version information ? (it should)

like [proxychains] DLL init: proxychains-ng 4.10 ?
on my non-el-capitan OS X, it does and it works

if that is so, someone needs to research which changes were introduced in 10.11 that breaks LD_PRELOAD and how to fix it.
possibly it's the guilt of this new "feature": https://en.wikipedia.org/wiki/System_Integrity_Protection

any idea how to fix it?

you could try to disable the system integrity protection (as described in the wikipedia article) temporarily to see if it makes proxychains work. if so, we can try to seek a permanent workaround.

yes, disabling it would led to success in working of proxy chains

Disabling SIP

Run csrutil disable in Recovery mode

@Willian-Zhang thanks for testing. now we can look if there's a way to disable the LD_PRELOAD "protection" "feature" for handpicked applications, in our case proxychains-ng.

@rofl0r any luck with this problem?

i haven't found any documentation about the LD_PRELOAD specific protection so far. we need to wait until more information is available (probably after the official release).

Reproduce the failure with proxychains4 curl http://ifconfig.co/ using the shown proxychains.conf on OS X 10.11, and compare it with the behavior when SIP is disabled. Investigate the proxychains-ng preloader and the OS X 10.11 SIP changes; done means proxychains works without requiring SIP to be disabled.
