Hi everyone, I'm trying to install Mac OSX Mavericks on an ACER Aspire 5920G laptop (Intel Core 2 Duo T5450, Graphics by NVIDIA GeForce 8600m GT). The first time I was attempting a boot in verbose mode, I got the "Configuration end, bridge x device 19" error. As the boot flags "npci=0x2000" and "npci=0x3000" weren't effective, I added IOPCIFamily.kext and AppleAPCIPlatform.kext in the Extra folder, which made the installation hang at "Configuration Begin". So I made a copy of IOPCIFamily.kext in the S/L/E folder, which corrected the error but gave me the "DSMOS has arrived" error. Now I tried to replace FakeSMC.kext with a new one, and I copied it into the S/L/E folder. I also deleted all graphic kext : AppleIntelHD*.kext, AppleIntelSNB*.kext, AMDRadeon*.kext, ATI*.kext, GeForce*.kext and NVDA*.kext, which didn't change anything. Of course I tried to boot with the "GraphicsEnabler=No" and the "-x" boot flags. One more thing, before the "DSMOS has arrived" line shows up, I noticed the following errors : "BootCacheControl: Unable to open /var/db/BootCache.playlist : 2 No such file or directory", "SuperIODevice : [Fatal] found unsupported ship ITE sequence ID=0xfc11, Winbond sequence ID=0xffff" Any idea on how to fix it ? Thanks for your time.
