Description
I followed #409 to check why proxychains4 not working on monterey, however, the default switch hookmethod=auto does not work on my recently updated macos (12.4). The expected log using Monterey style DYLD hooking did not show up.
I tested by adding lines to configure, in check_define __APPLE__ section
osver=$(get_define_stripped __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 2>/dev/null)
+ echo "xxx osver=$osver"
it outputs
xxx osver=110300
It definitely not correct. I have to add --hookmethod=dyld to ./configure to make it work correctly.
Does it seem the correct way to detect MacOS version is the command sw_vers?
$ sw_vers
ProductName: macOS
ProductVersion: 12.4
BuildVersion: 21F79

Research direction
Start in configure, especially the check_define APPLE section that reads ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED. Compare that value with sw_vers on macOS 12.4 and trace how hookmethod=auto selects the hook mode. Done means auto selects Monterey-style DYLD hooking and the expected log appears without passing --hookmethod=dyld.
