ExtPack installation fails for VirtualBox 6.0.8 on OSX 10.14.5

[RudyMLE]

So , it seems that the recovery mode allows to install and run 6.0.8 on 10.14.5 - but still cannot install theOracle_VM_VirtualBox_Extension_Pack-6.0.8... The error is:

Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib'): VERR_FILE_NOT_FOUND - dlopen(/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib, 6): Library not loaded: /Applications/VirtualBox.app/Contents/MacOS/VBoxVMM.dylib

Referenced from: /Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib

Reason: Incompatible library version: VBoxPuelMain.dylib requires version 6.0.8 or later, but VBoxVMM.dylib provides version 5.2.30.

I split your post from the "installation fails for vbox 6.0.8 on osx 10.14.5" thread. You don't have the same problem, not at all. Please read "Do not highjack other threads, create your own. Choose the title carefully."

VBoxPuelMain.dylib requires version 6.0.8 or later, but VBoxVMM.dylib provides version 5.2.30.

It seems that you're trying to install a different version of the ExtPack from the VirtualBox version that you have. Please make sure that the ExtPack version matches exactly the version of the main program.

So , it seems that the recovery mode allows to install and run 6.0.8 on 10.14.5

You do not need to boot in Recovery mode to install VirtualBox 6.0.8 anymore. Please read carefully the 1st post from the thread which I split your post from, the red letters part...

Thanks, will do.

How can I check my version ? the about box only states the UI version (Version 5.2.30 r130521 (Qt5.6.3) ).... Checking for updates says "You are already running the most recent version of VirtualBox."

You do not need to boot in Recovery mode to install VirtualBox 6.0.8 anymore. Please read carefully the 1st post from the thread which I split your post from, the red letters part...

If I made the change before in order to all the installation to complete, should I uninstall and somehow revert the change that I have done in the command line in the recovery mode?

Thanks again.

Download the latest VirtualBox from http://www.virtualbox.org/wiki/Downloads. In the same page you'll find the matching ExtPack, download that too. Install VirtualBox, then install the ExtPack.
