Unable to install Extension Pack

[isend]

(macOS 10.10.5)

My VirtualBox stopped working after I upgraded it to the current version. Error message is:

Implementation of the USB 2.0 controller not found!
Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings.
Note! This error could also mean that an incompatible version of the 'Oracle VM VirtualBox Extension Pack' is installed (VERR_NOT_FOUND).

I tried to install Extension Pack from Preferences > Extensions, but failed (I had made sure that I used the same version extension pack as my VirtualBox). Then I tried the command in Terminal:

Code: Select all

sudo VBoxManage extpack install --replace Oracle_VM_VirtualBox_Extension_Pack-6.1.8.vbox-extpack

but got error messages as follows:

I then tried to downgrade VirtaulBox by installing older versions, but alway got the same error message when I tried to install Extension Pack for it. How should I resolve this problem? Thank you.

I have had the same problem since I upgraded to 6.1.6, I am also running MacOS 10.10.5. I was hoping the problem would fix itself when I upgraded to 6.1.8 but the problem still persists. I can still boot my instance minus the extension pack which limits connecting USB devices. I have tried to add the extension pack through the GUI as well through the command line interface, same error every time. Hoping someone posts a fix here.

IIRC there was a problem some time back where something couldn't be installed from the Downloads folder on a Mac.
Could you try moving the extpack to a less "protected" folder and try again?

Downloaded to a different folder, same result and same error.

I cannot post a fix, but I can tell you what the problem is:

While the (executable) files in VirtualBox 6.1.8 are signed using sha256 and sha1, the (executable) files in the VirtualBox Extension Pack 6.1.8 are only signed using sha256, and therefore cannot be verified under older macOS versions (< 10.12 AFAIK). I don't know if this is intended.

You could search the Bugtracker and create a new bug ticket if necessary.

I got it work on my mac downgrading Virtualbox all the way back to 6.0 just for test sake. Not sure at what version it fails.

I just wanted to confirm that I am facing the exact same issue and the exact same solution worked for me. OS X 10.10.5, extension pack installation works on Virtualbox 6.0.0 but not on e.g. 6.0.22 or 6.1.10 (I did not try all available versions).

Thank you. Downgrading it to 6.0.0 works for me, too.

I am runnig Mac OS X 10.10.5 as host and I was able to install VirtualBox 6.1.8 r137981 (Qt5.6.3) in combination with Extension Pack 6.1.2r135662.
I tried Extension Packs 6.1.4, 6.1.6 and 6.1.8 as well but got the same error messages as shown above. The Extension Pack 6.1.2 also worked with VirtualBox 6.1.4 which I figured out after I tried to install the Extension Pack 6.1.4 and it was not possible.

While the (executable) files in VirtualBox 6.1.8 are signed using sha256 and sha1, the (executable) files in the VirtualBox Extension Pack 6.1.8 are only signed using sha256, and therefore cannot be verified under older macOS versions (< 10.12 AFAIK). I don't know if this is intended.

It seems that this problem has to do with the outdated Mac OS Version Yosemite and I think it should be gone if we upgraded it to a more recent version.
