Complete Guide to Fix VirtualBox Errors While Installing Mac OS X

In this article, I’m going to show you the complete guide to fix VirtualBox errors while installing Mac OS X. Most of the website that creating content regarding the installation of Mac OS X El Capitan or macOS Sierra on VirtualBox is not complete and have errors. The article might be correct and work on one device perfectly and without any problem. But there are lots of devices and different kinds of errors. Some months ago, we’ve created an article on how to install Mac OS X El Capitan on VirtualBox and the visitors has got different kinds of problems.

One of our visitors “Holk” has read all the necessary comments and collected all the errors together and told the solutions. Here is his comment.

First THANXALOT to Mukhtar Jafari for all of his work! Great!
I needed more than 3 hours getting it to work. I was stuck in most of the errors mentioned above. Only with hints out of the comments i got it working. I`m merging it here so not anybody else will have this pain.

Creating the VM is easy, I´m not mentioning it here (just get vram to 128 mb!), problems were caused by the code (whatelse?!).

1) command prompt as admin

2) Mukhtar Jafari says: May 23, 2016 at 4:06 PM -> vboxmanage error

Aha, Add one more hyphen then try once again. Because when you copy and paste the code from Website
there will appear only one hyphen so use double hyphen *–* before cpuidset

3) LoThAr says: May 21, 2016 at 3:47 AM -> VBoxManage error: Could not find a registered machine named ‘”OS’

None of the solution posted worked for me, so, there is a way that cannot fail. Follow this steps:

In the DOS prompt type:
VBoxManage.exe list vms

You’ll see all your Virtual Machines (in case you have more than one). At the right of the Mac image is the GUID of the machine. Copy that GUID an replace it for the name of the VM in the command.

For example:

VBoxManage.exe list vms
“ZENTYAL2” {f5ee0212-7ca4-4710-b30e-b7e2ee881cb9}
“IE9 – Win7” {6730b42b-d555-4729-9948-711159678cac}
“Mac OS El Capitan” {9089dae0-6372-4c00-b415-b8963d54535f} “Missing Bluetooh Controller” error

You are getting the “Missing Bluetooh Controller” error because you are running the commands (Step# 5) while the Oracle VM software is open. Shut down the VM software completely and then run the commands. After the commands are ran, open up Oracle VM and start your VM session.

Dude, I know what is the error. If you copy code from the website, try to change ” with your open inverted comma “. It is the error. After I changed the line with my open inverted comma for Search and Replace, then the problem solved. Make sure that you use your own open inverted comma in every single line. Try to check and replace it. Search and Replace doesn’t replace all the lines sometimes.

These tips solved also the “considerRebuildOfPrelinkedKernel com.apple.kext.triggers triggered rebuild” error!

Conclusion: Wouldn´t it have been easier to add an ANSI-textfile with the right code to the downloads list?!

Nevertheless: Thanx to all of you!
