Fix typo in README.md
Tick to v8.2.4
Update README.md
Mac might be working now;
I dont have one to test on, but it seems the code simply wasnt chdir-ing on Macs;
Looking at the docs, it seems Mac has the chdir() function inside unistd just like other *nix;
Thus I just changed the code so Mac and *nix are both in the same #else
