    Upgraded to Fusion 10.0.1-Pro and now getting "Cannot find a valid peer process to connect to" error

    amuir2k Lurker

      Prior to posting this, I looked at a lot of the solutions posted for the issue.  I've tried multiple variants of full uninstall-reboot- reinstall and I've tried Wila's trick to make sure Gatekeeper hadn't crippled the installer DMG, but all to no avail.

       

      I'm on a a 2013 Mac Pro  running OS X 10.12.6.  I'm not getting any message in the Security & Privacy center.  Prior to upgrading to 10.0.1, I was running Fusion 8 with no issues.

       

      I saw a technique mentioned regarding booting into Recovery mode and then using the terminal to set the kext-consent status to disabled, but hoping this isn't required.

       

      I can upload a Fusion problem report if that would help.

       

      Any ideas?

       

      Thanks in advance . . .

          Hi,

           

          If you didn't see the kernel extension consent popup and haven't specifically been able to approve the kernel extensions then that probably still is your issue.

          Did you also try the trick where you move the install to another folder (say Desktop) - using Finder (mandatory to use Finder) - and back to the Applications folder?

           

          FYI, I summed up the known workarounds/solutions at a blog post here:

          VMware Fusion on macOS High Sierra - System Extension Blocked - PlanetVM

           

          Rich Trouton also has an interesting article on the topic with a bit more background information over at this blog.

          Kernel extensions and macOS High Sierra | Der Flounder

           

          You should normally not have to disable this extra protection, but there are quite a few people where the consent dialog is not being displayed and where no "Allow" option shows up, so you are certainly not alone.

           

           

          edit: Wait.. wait... you are seeing this on 10.12? Aka Sierra, instead of High Sierra? There is no "Allow System Extension" button in Sierra... so that at least is not your problem.

          It might still be the gatekeeper issue where the downloaded file is tagged in quarantine  (and so the move folder using Finder trick might still work)

          Do you see that the quarantine flags are removed after removing them with xattr -dr ?

          Eg: Does "xattr -l ~/Downloads/VMware-Fusion-10*.dmg" still show "com.apple.quarantine" or is that gone?

            Hi Wil,

             

            Thanks for your reply.

             

            Yes, this is on 10.12.6 (Sierra) so, unexpected.

             

            I did not see  com.apple.quarantine after running xattr -l, where in the output text would I expect to see that?  I tried searching for "quarantine"in the terminal window after the xattr -dr, but didn't get any hits.

             

            Any thoughts for confirming the issue is kext not loading?  - or - perhaps I am better off upgrading to High Sierra?

             

            Thanks,

              Hi Art,

               

              When you download a file gatekeeper will add a special tag so that it is known that the file was downloaded from the internet.

              This is for extra protection of not running malware on your system.

               

              The xattr -l command displays the details for that.


              Here's a -shortened- output of a VMware Fusion setup file that I just downloaded.

              The xattr -dr command helps you to remove the extra tags.

               

              There can be other reasons for the kext not loading, but you can certainly try and upgrade to High Sierra, but it should not be needed.

              I'm not sure, but I get the feeling something else is going on.

              Perhaps your host has run out of character devices, although I would have expected to see a different error, see also Fusion 5 - Could not open /dev/vmmon: No such file or directory.

               

              Perhaps it is best to open a support case with VMware?

              To get official support please go to: Fusion Support and open a ticket at File a Support Request

                Hi Wil,

                 

                Thanks so much for your further sleuthing.

                 

                I ran xattr -l again just to confirm and indeed, there is no com.apple.quarantine string in the output.

                 

                I took your advice and opened a support case with VMWare, hopefully they can figure it out.

                 

                If I get a solution, I'll let you know as you seem to be a keeper of arcane VMWare knowledge.  ;-)

                  Ever figure this out? I had the same problem in 10.12, so I upgraded to 10.13, and same problem. I've tried everything. And I've never gotten the blocked message in the Security pref pane even once.
