Tomas Chlebek Okusha I-MacBook Pros phakathi kwezinye izinto, ishintsha umsebenzi wokuvula isivalo. Bangase bavele bavuke ngokwesiko, noma bavule. Kodwa umsindo ojwayelekile obuhambisana nokuvula kusukela kudala unyamalele. Imiyalo elandelayo ingasetshenziswa ukuyibuyisela, futhi uma ungathandi ukuqala uhlelo ngokushesha ngemva kokuvula isivalo, ungasivala.
Okokuqala, kufanele kuqashelwe ukuthi lokhu ukungenelela ohlelweni, ngakho-ke kuyadingeka ukulandela imiyalelo ngokuqondile futhi ugweme noma iyiphi ingozi, kungcono ukuyeka umsindo lapho uvula. Nokho, lena inqubo elula futhi ukufaka imiyalo elandelayo ngeTheminali akufanele kubangele noma iyiphi inkinga.
Vula iTheminali (Izinhlelo zokusebenza > Izinsiza) bese uthayipha/ukopisha kuwo owodwa wemiyalo engezansi. Qinisekisa okufakiwe ngakunye nge-Enter bese ufaka iphasiwedi yakho yomlawuli.
Umyalo wokunika amandla umsindo ekukhuphuleni amandla:
I-sudo nvram BootAudio =% 0
Yala ukuze ucime umsindo uma uvula amandla:
I-sudo nvram BootAudio =% 00
Umyalo wokukhubaza ukuqala ngemuva kokuvula isivalo:
Isudo nvram AutoBoot =% 00
Yala ukuze uvule ukuqala ngemva kokuvula isivalo:
Isudo nvram AutoBoot =% 03
Ikhono lokuvula nokuvala ibhuthi ngemva kokuvula isivalo ingeyabanikazi beMacBook Pro entsha kuphela, ikhono lokuvula nokuvala umsindo wokuqalisa kuwo wonke umuntu.

AmaMac abelokhu ememezela ukwethulwa kwawo ngomsindo ofanayo kusukela ngasekupheleni kweminyaka engamashumi ayisishiyagalolunye. Ekuqaleni, ibinomsebenzi ongokoqobo - "i-gong" imemezela ukuthi uhlelo luqala ngaphandle kwezinkinga. Kodwa kusukela lapho, ingoma engaphansi kancane kune-G-flat major/F-flat major isibe yisakhiwo sodumo futhi isithole nesimo sobuhle.
I-chord phakathi kwe-F flat major kanye ne-G flat major?
F# === Gb
Ukulinganisa kusebenza kuphela ekushuneni okunomoya olinganayo, kokunye, isb. ukushuna okuhlanzekile, akusebenzi ngendlela enembile.
cha, kuyafana emculweni weshidi
Cha, kuyafana noma ngabe ukushuna.
Sengivele ngiwutholile 'umthombo':
"Uhlelo lokusebenza lophawu lwentengiso lwe-Apple luthi" uphawu luqukethe uphawu lomsindo oluhlanganisa indawo ephansi kancane (cishe amasenti angu-30) G flat/F iculo elikhulu elibukhali." Ungalanda i-chime yokuqalisa lapha. "
ngakho-ke kungukuhumusha okubi nje;)
Ngiyavuma ukuthi ngangingagxilile ngokugcwele lapho ngibhala leso sigaba, ngakho angizange ngiqaphele ukuthi i-Fis ne-Ges ngokuyisisekelo iyinto efanayo.
Kuma-macbook amadala, vele uvale umsindo. Uma ngehlisa umsindo ube ngu-0% ngaphambi kokuwuvala, i-gong ngeke izwakale ngemva kokuyivula, uma ngingakwenzi lokho, izozwakala. Ngabe ngiqonda kahle ukuthi lokhu bekungavumelekile isikhathi eside?
Angiqiniseki…kubukeka kusebenza kwamanye ama-MacBooks hhayi amanye. Noma kunjalo, imiyalo ku-athikili eyokuvala umsindo unomphela, kungakhathaliseki ukuthi ingakanani ivolumu yesistimu ngaphambi kokuvala ikhompuyutha.
Manje ngizamile ukucisha umsindo we-boot ku-MBP Retina 2014 ngisebenzisa umyalo oshiwo sudo nvram BootAudio=%00, kodwa ayizange isebenze - umsindo we-boot usadlala.
Sawubona, angikwazi ukuyithulisa maphakathi no-2014...
Ezinye izindlela zimi kanje:
ukukhubaza: sudo nvram SystemAudioVolume=%80
ukunika amandla: sudo nvram -d SystemAudioVolume
noma okunye ukuhluka kokuvala shaqa:
sudo nvram SystemAudioVolume=%01
sudo nvram SystemAudioVolume=%00
sudo nvram SystemAudioVolume=” “ (isikhala nje ngemva kophawu olulinganayo, azikho izingcaphuno)
