I-OWC ikuthole lokho kukhona isibuyekezo semfihlo se-firmware esivumela ama-MacBooks kusuka ngo-2008 (ngasekupheleni kuka-2008) ukufaka i-8GB ye-RAM.
Ekupheleni kuka-2009 ukuvuselelwa kwavela ukuxazulula umsindo owedlulele ku-optical drive, kepha uma ngabe i-Mac yakho ibuyekezelwe enguqulweni edlule, isibuyekezo asibonanga. Lokhu kubuyekezwa kuvunyelwe ukufaka i-8GB ye-RAM kunoma iyiphi i-MacBook, yize ingakubekanga ngokusobala.
Isebenze kumamodeli alandelayo:
● IMacBook 13.3 ″ 2.0GHz ne2.4GHz
● IMacBook Pro 15 ″ 2.4GHz
● Imodeli yeMacBook Pro 15 ″ 2.53GHz ene-ExpressCard Slot (Ngasekupheleni kuka-2008)
● Imodeli yeMacBook Pro 15 ″ 2.8GHz ene-ExpressCard Slot (Ngasekupheleni kuka-2008)
Bheka inguqulo yakho ye-BootROM kuphrofayili yesistimu bese uqinisekisa ukuthi yi-MBP51.007E.B05 yama-MacBook Pros ne-MB51.007D.B03 yama-MacBooks.
Uma inguqulo yakho ingafani nezinombolo ezingenhla kufanele ulande isibuyekezo esilandelayo:
● IMacBook Pros (MacBookPro5,1): Isibuyekezo se-MacBook Pro EFI Firmware 1.8
● I-MacBooks (MacBook5,1): Isibuyekezo se-MacBook EFI Firmware 1.4
Ngemuva kwalokho qiniseka ukuthi une-Snow Leopard 10.6.6 efakiwe, okuyilapho ukuhlolwa kwenziwe khona, futhi manje usungakwazi ukufaka i-8GB ye-RAM yakho.
