Commonly Asked Questions Q: What are the solutions to the 'Still waiting for root device' messageA: The most common solution is making your OSX drive the primary IDE. Try disconnecting all the other hard drives, make the OSX drive IDE0, using either cable-select or Master jumper settings. What does “Still waiting for root device” means? It means that a driver/kext for the source from which you are booting is not detected properly by the mac operating system (USB kext not detected or loaded) Mac OS released prebuilt with the latest drivers that supports SATA out of.

Hi and thanks for any help you can offer,

My Mac has been working at 10.10.2 and previous versions with a Crucial CT480M500SSD1 SSD for seven+ months until I updated to 10.10.3 (which may be coincidental). Now, I cannot boot from the drive with the eventual message 'Still waiting for root device'.

Things I've tried:

1. Firstly the error I had was a grey screen with a mouse pointer I could move on it but nothing else would happen. Because I have a bluetooth keyboard I couldn't boot to safe mode or reset the PRAM directly, so I took out the SSD drive and booted to the time machine partition. From there I used e.g. nvram boot-args='-x -v' to boot to safe mode, which worked and I rebooted immediately, subsequent boots would not work at all, even to safe mode.
2. Still without a USB keyboard I used the Time Machine partition (pulled the SSD out to boot to it) to reset PRAM (via boot-args), NVRAM, didn't work.
3. I brought a USB keyboard home and used it to boot to TM and restore a 10.10.2 version of the SSD from before the update. Same problem. I have even restored versions from December with the same result, as above.
4. I have a previous SSD laying around with Mavericks on it, it boots fine.
5. I have run bless --folder /Volumes/Beep Beep/System/Library/CoreServices --bootefi

Any other ideas or can anyone give an explanation of how the root device is determined and found? I've read some things about needing to have kexts that read from the drive, but it doesn't seem like

Thanks, Dan.

[edit] nForce SATA

[edit] No detection of SATA at boot in nForce3 once MacOS 10.4.6 is installed

After installing OS X 10.4.6 native with VMware with any of the method listed in the installation guides, the first boot was OK, configure the OSX with keyboard, personal info, etc..But when you turn it off and on again, it freezes in the holy 'Still waiting for root device'.My solution was, start OSX with the -v -x flags, for my surprise it recognize the SATA disk and start in safe mode. Then i went to Terminal, entered as root and typed the following..(extracted from 'AppleVIAATA.kext' Method)

Then rebooted and everything worked fine..

Mac Os High Sierra Still Waiting For Root Device

Seems like reloading the extensions cause OSX load the SATA driver correctly at boot. If someone know why, you are welcome :) .reply for why does this happen-----when i was installing osx with windows installed,i by mistakely deleted the windows partition which became in red coloured text...i thin something important file was deleted ...

[edit] You can use chroot to run this from the installer disc

Note that you can operate on an already-installed copy of Mac OS X from the install disc by accessing the Terminal utility. kextcache will crash, however, as it doesnt have write access to /tmp (as its mounted to a location on the read-only optical disc). You can work around this by running another instance of bash inside of chroot.. type chroot /Volumes/MyOSXInstall bash and the new bash shell will have a root path set to the root path of your installed volume. kextcache will work correctly. . .

[edit] Other Problems

Likely problems:
SATA
Hard drive not set as Primary Master
Incompatible hardware
CMOS Checksum Bad Error

Solutions:
'AppleVIAATA.kext' Method
Make Hard drive Primary Master hd 1
If you are using a SATA disk, make sure it is set for IDE legacy mode in the PC BIOS and not 'enhanced'
Get a IDE Hard Disk(you can attach the IDE hard disk, but still install the OS on the SATA drive. It just helps to get past the 'still waiting for root device error'.)
If accompanied by a CMOS checksum bad error at boot, reload BIOS optimised defaults, change to AHCI and HPET to 64-bit mode.(Post them if it is not listed)
Unplug all drives from the motherboard (CD/DVD) except the install drive and install via a USB DVD drive. It seems that OSX86 tries to install to a DVD drive on occasion. This worked for me on 7 different machines with this issue. You may reconnect after the install.

BootLoader
Sometimes the version of the BootLoader is too old or too buggy that it can't detect the Hard-diskso Try to update the boot loader version manually voodooprojects.org
or using any Automatic Tool Like 'Chameleon Wizard' or 'Champlist'
