Amit_ Posted January 2, 2017 Share Posted January 2, 2017 Hi, I made USB with Pandora's box and when I boot from USB in verbose, I see this: Can someone help? I tried safe mode, but no difference.

mnfesq Posted January 2, 2017 Share Posted January 2, 2017 Waiting for root device when booting from USB means that your USB kexts are not loading so your computer can't find the USB drive to load the remainder of the operating system needed to boot. I can't tell you why you are getting this error without more information about you Pandora options. You might need to try making your USB installer again with different options.

I chose the normal Pandora options, not the createusb method. And I used Clover not Enoch.

nawcom Posted January 2, 2017 Share Posted January 2, 2017 Amit_ it looks like your Toshiba model uses an Intel HM55 chipset which needs a DSDT mod to get USB working in 10.11+ by renaming EHC1 to EHCA and EHC2 to EHCB and injects device-id and AAPL,clock-id values into it, according to another DSDT I'm looking at from a laptop that is also HM55. They use MacBookPro6,1 as the Mac model. If you haven't tried ACPI->FixUSB in Clover Configurator or USBInjectAll.kext then you can give them both a try, but if it doesn't fix anything then upload your DSDT and I'll patch these USB fixes into it. For EHCA: Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { Local0 = Package (0x04) { "device-id", Buffer (0x04) { 0x34, 0x3B, 0x00, 0x00 }, "AAPL,clock-id", Buffer (One) { 0x01 } } DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } For EHCB: Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { Local0 = Package (0x04) { "device-id", Buffer (0x04) { 0x3C, 0x3B, 0x00, 0x00 }, "AAPL,clock-id", Buffer (One) { 0x01 } } DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } 2 Link to comment https://www.insanelymac.com/forum/topic/319824-waiting-for-root-device/#findComment-2343027 Share on other sites More sharing options...
