 OS X syscalls:
 https://opensource.apple.com/source/xnu/xnu-1504.3.12/bsd/kern/syscalls.master
 427     AUE_FSGETPATH   ALL     { user_ssize_t fsgetpath(user_addr_t buf,
 size_t bufsize, user_addr_t fsid, uint64_t objid) NO_SYSCALL_STUB; } {
 private fsgetpath (File Manager SPI) }
 180     AUE_KDEBUGTRACE ALL     { int kdebug_trace(int code, int arg1, int
 arg2, int arg3, int arg4, int arg5) NO_SYSCALL_STUB; }

 These syscalls are needed for some GUI apps.

 I have not tested on torsocks 2.3.0 as it doesn't build on OS X - see
 issue #28538
