Into yokuqala okufanele siyazi ukuthi kusho ukuthini ukufaka iphasiwedi ye-firmware ye-Mac. Lokhu kuyinto elula ukuyiqonda futhi ngokuyisisekelo ukusivimbela ekuqaliseni uhlelo kusuka kudivayisi yokugcina yangaphakathi noma yangaphandle ihlukile kune-boot disk eshiwo wemvelaphi.
Ingasetshenziselwa ukuvikela i-boot ingasetshenziswa ukuvimba inhlanganisela yokhiye abaningi be-boot efana ne-Command-R, Option-Command (⌘) -PR, Command-S nabanye.

- Ngemuva kwalokho kufanele chofoza ku-activate Firmware Password.
- Sifaka iphasiwedi ye-firmware emkhakheni bese uqhafaza Setha iphasiwedi. Kubaluleke kakhulu ukukhumbula le phasiwedi ngoba kuzodingeka ngokuzayo futhi uma siyikhohlwa kuzodingeka sidlule ku-Apple Store noma umhlinzeki ogunyaziwe one-Mac kanye nerisidi noma i-invoyisi yokuthenga imishini.

Sizofaka iphasiwedi ye-firmware lapho uphawu olunengidi luvela kanye nenkambu yephasiwedi esinayo esithombeni sikanhlokweni.
Konke lokhu kuyafana kubasebenzisi abane- uhlelo lokusebenza lwamanje noma oludala kuze kufike ku-OS X Mountain Lion, kokudlule akusasebenzi. Ukukhubaza iphasiwedi ye-firmware, sizophinda izinyathelo zangaphambilini, kepha ngokuchofoza ku- Khubaza i-Firmware Password kusinyathelo 3.
