marmotta Posted September 2, 2015 Share Posted September 2, 2015 Non ci avevo mai fatto caso in quanto ho sempre aggiornato dall'appstore fin da Lion, ma in questi giorni ho dovuto far ricorso al boot tramite usb per ripristinare il sistema con Time Machine a causa di un crash del filesystem... operazione semplice che è diventata complicata dal fatto che non c'è stato verso di fare il boot tramite usb! Ho risolto mettendo tutti i file di installazione in un Hdd collegato alla porta SATA, ma il problema irrisolto rimane... perchè non c'è verso di fare il boot da Usb? Lo stesso Hdd collegato tramite USB non va, idem per le chiavette. Clover su partizione EFI si carica correttamente, come correttamente si avvia il kernel... fino a quando arriva il messaggio "waiting dsmos..", si attiva la rete e poi il classico messaggio del Bluetooth, e piu nulla! Ho provato tutte le combinazioni di clover possibili ed immaginabili, Fakesmc è all'ultima versione..... boooo! Qualcuno ha idea di quale sia il problema? Mavericks da usb si avvia correttamente...

spakk Posted September 3, 2015 Share Posted September 3, 2015 write your hardware specifications, since no one else can make a statement. ... I think that it is up to the graphics card, or to a lack of drivers. Graphics drivers are not loaded. Link to comment Share on other sites More sharing options...

spakk Posted September 3, 2015 Share Posted September 3, 2015 My hardware is in my signature This is what I found for your board with Nvidia Graphics Card!! Set BIOS to the following: Intel Speedstep Disabled Intel Virtualisation Disabled Limit CPUID Disabled Primary PEG (Video) AUTO Internal Graphics Memory Size 64MB AHCI On 2nd Marvell Controller Off Bluetooth Disabled Asmedia USB 3.0 Disabled Intel LAN Disabled High Precision Event Timer On EFI BIOS Priority Connect monitor to the Nvidia last DVI ports or first HDMI ports and SATA drives to white Port0 or Port1. Try to boot with this flags: -v -x GraphicsEnabler=No npci=0x2000 EDIT: excuse me, I use my smartphone and have overlooked the small font. Link to comment Share on other sites More sharing options...

spakk Posted September 3, 2015 Share Posted September 3, 2015 with Chameleon bootloader use this flag: USBBUSFIx = YES. If you have a general problem with usb, then create a dsdt and use the patches of rehabman: https://github.com/RehabMan/Laptop-DSDT-Patch Link to comment Share on other sites More sharing options...
