Still Wait For Root Device In Mac

  • In Verbose mode it crashes half way, a 'no entry' icon pops up and the last text says 'Still waiting for root device'. I followed all the instructions one by one. I tried it in multiple USB drives and different ports; tried creating the installation drive with Unibeast and Terminal command; tried the latest and previous Clover EFI bootloaders.
  • Still waiting for root device means that Mac OS X wants to find your HDD, but doesn't have the means to do it. Usually it comes down to: - Disk not supported - Connection not supported.

When you install Mac OS X on a non-Apple hardware device called a Hackintosh, you are likely to face the problem of “Still waiting for root device”. This is the message you get when you try to boot Mac OS X. This message illustrates that the disk containing the OS X image is not booting properly. This message keeps on repeating, and you cannot move forward till you find some solution for it. This article shows how to fix “Still waiting for root device” on your Hackintosh.

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).

This solution works for people who have installed Leo4all v3 and received the message upon rebooting. The cause of the error is due to incompatible or incorrect configuration of the ATA controller.

How to Fix Still waiting for root device

Still Wait For Root Device In Mac Catalina

Boot your PC using LeoV3 DVD as if you are reinstalling Mac OS X again.

Select the Terminal from the installer’s Utility menu.

Now, you have to copy all the kexts from the DVD to your hard drive.

For performing this task, you need to use the following command:

cp -pr /Volumes/Leo4allv3/System/Library/Extensions/*ATA* /Volumes/MacHD/System/Library/Extensions/.

You need to replace Leo4allv3 with the name of your DVD. Also replace the MacHD with the name of your hard drive volume.

Set the permissions for the kexts you have copied. For this purpose, you need to use the following command in the terminal:

chown -R root:wheel /Volumes/MacHD/System/Library/Extensions/*ATA*
chmod -R 755 /Volumes/MacHD/System/Library/Extensions/*ATA*

Now, you need to remove the kextcache by using the following command:

rm -rf /Volumes/MacHD/System/Library/Extensions.*

Now, reboot your PC. It is highly recommended to press F8 when your PC is booting and then enter “-f” as the boot option to force reloading of the kexts.

It is not completely sure that this strategy might work for your Hackintosh, but still this solution is the most feasible one as reported by many people who suffered from the “Still waiting for root device” issue. You might try exploring more settings if your problem is not solved by using the technique mentioned in this article.


This annoying statement ususally comes up befor DVD can boot or after installation before the OSX boots for the first time.

if you haven't used a Leo4All or did not use -v option then the screen will not look like the first image in this post but it will look like this (no entry sign/ stop sign/ no smoking sign without the cigaret):

What does this error mean?
well it means that the OS is set to boot from a drive and partition that does not exist.
for instance the Darwin boot loader is talled to boot from Disk1 (Disk 1= second hard drive (starting from 0)) and there is no such disk.
What can you do?
if you know the number of your Hard Drive then at the Darwin prompt (after boot press F8) write: rd=DiskX where X is the number of your OSX hard drive.
for instance if your hard drive is 0 (zero is the first hard drive) then write:
rd=disk0
if you do not know your hard drive then there is a try and error method of trying all the disk possibilities on your computer starting with: rd=disk0 then rd=disk1 then rd=disk2 then rd=disk3 etc.
another good option is to disconnect other HD and leave the OSX HD as first and write disk0.
How to set the RD for every boot?
once you succeed and don't want to write the rd parameter every boot, then write it in your boot plist file.
this is a file that configure the system boot parameters. the file can be found at: /Library/Preferences/SystemConfiguration
the file name is: com.apple.Boot.plist and you edit it as root and change the Kernel Flags value and add to it the rd parameter like this:
  1. open terminal
  2. write: sudo -s and press enter
  3. enter your password when asked and press enter
  4. write: vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and press enter
  5. in the vi editor use the arrow keys on the keyboard and navigate the cursor to the tag: after the <key>Kernel Flags< /key > line.
  6. the string tag might be empty or not, if it is not empty then add space and then write: rd=diskX where X is your hard drive number.
  7. press keyboard button Esc (in order to exit insert mode)
  8. write: :wq and press enter (notice the : sign)
  9. then reboot and thats it
here is a Bofore image of my file (it will help clear things up):
and here is the after image (note the space between the -v and rd parameter):

most common mistakes are to write full path to the drive like this: rd=/dev/rdisk0or rd=disk0s2 instead of: rd=disk0. (only when you are trying to load the install DVD, not after the install has finished successfully).
the rule is that before the install (if the DVD will not load) then use the rdiskX format.
if you are after the install then use the rdiskXsY format.

after the install has finished successfully and you get 'Still waiting...' then you can use the partition value as well in this form:
where X stands for the number of the leopard disk and Y stands for the partition number of the leopard disk. examples:
disk0s2 (first disk second partition)
BIOS options
there is another option that your bios is not set as required.
if you have a SATA hard disk, then they can support several work modes,
IDE legacy, or IDE native, or native AHCI, also there is a S.M.A.R.T mode that can be enabled or disabled, and the actual strings as always depends on your BIOS.
i also had an option of 'Hard Disk Pre Delay' that gives the hard drive delay time in order to let the hard drive time to react after reboot and when disk is mounted or plugged in, i set it to 5 instead of default 0.

so you should play with these options until you cover all options one of them will fix your 'Still waiting...' situation.

Configure SATA as: AHCI

and a closer look:

this option not always work, it didn't fix the problem forever, but i have successfully finished the install process.
follow these next steps:
  1. boot from the install DVD into single-user mode
  2. flag any partition other then the leopard partition as bootable
  3. then you reboot, again from the install DVD into single-user mode
  4. next flag back the leopard partition
thats it it should help, if you have any problem please post here,
Enjoy.
