Guest Addition issue: cannot share folder

Post by minh.nkim »

Hello: I am aware that this topic was previously discussed and resolved but upon trying the solutions from previous postings, I still can't make this work!

My issue: failed to install Guest Additions on Windows 10 host to share folder
Setup: host is Windows 10; VM machine is macOS Big Sur.

What I have done:
1. Sucessfully installed VM mac OS Big Sur. It is working fine
2. Defined and configured shared folder on host machine (windows 10)

3. I tried the following to reproduce the solutions, read from previous postings about similar topic. Unfortunately ALL attempts FAILED to install guest additions
a) Shutdown VM; unmount/release, mount the Guest Addition iso
b) Tried different Graphic Controller settings: VBoxVGA, VBoxSVGA
c) Launched guest addition "VBoxWindowsAdditions.exe" from host

I have attached a few log files and screenshoots of what I have done. Please see attached zip file:

1. "Insert CD Guest Addition Error.png" shows the VBoxGuestAdditions.iso is not mounted, error (VERR_PDM_MEDIA_LOCKED). I don't understand why the guest VM can see but VirtualBox device manager said it cannot mount it.
2. "VM Log": this is the log of the VM
3. "GuestAdditionError.png" and "GuestAdditionError.txt" are screenshot and its logs describing the error. It appears that the application cannot find VBoxGuest.inf in C:\Windows\System32\DriverStore\FileRepository\vboxguest.inf_amd64_c4ea20f713fb03c4\

Please help as I have been trying to solve this issue for a few days!
Thank you in advance for your help.

Your log shows a MacOS guest on a Windows host, not the other way around.

There are no "GA Shared Folders" for MacOS guests. In fact you should note that the user manual doesn't mention MacOS Guest Additions at all, so anything that exists is not supported.

That note was for future bona fide users of Mac OS guests, which you are not: see FAQ: Mac OS X Guest on a Windows Host.
