System preferences -> Sharing -> Internet
Sharing your connection using: Built in Ethernet
Pune bifa la: To computers using: Built in Ethernet
Click pe butonul de Start ca sa pornesti sharing-ul
Deschide un Application -> utilities -> terminal
da comanda ifconfig
o sa afiseze ceva in genul:

la en0: ai 2 linii cu inet
prima adresa trebuie sa fie cea “oficiala” pin care ai internet
a doua (la mine 192.168.2.1) e cea de sharing.
Te duci pe PC si ii dai asa:
Ip address: 192.168.2.2 (sau cum o fi la tine - schmbi doar ultima cifra)
netmask: 255.255.255.0
Gateway: 192.168.2.1 (adresa a doua de la mac)
DNS: ce_dns_ai_setat_si_pe_mac
Enjoy. Dar:
1) oricine din retea poate sa ia net prin mac-ul tau daca isi pune o adresa de aia gen 192.168.2.x si adresa a doua macului tau la default gateway.
2) providerul tau de internet poate foarte usor (daca il duce cat de ca capul) sa vada ca faci chestia asta.
3) oricine din retea pe care se pricepe poate sa vada ce adrese folosesti si sa faca punctul 1)
Va multumesc tuturor ca v-ati batut capul cu problema mea!
