    Contradictory advice for OSX guests

    dlhotka Virtuoso

      Just installed the new DP, and on reboot, got this message: which seems to contradict previous comments here (that OSX doesn't work well on machines with less than two cores).

       

      Can we get some clarification?

          Hi dlhotka!

           

          I haven't yet tried the latest DP (I'm actually on vacation right now... )... so my troubleshooting will be a touch limited: Has this VM ever contained anything prior to Yosemite?  Besides a bug/incompatibility between Fusion and the latest DP, one way this particular error message could occur would be if the wrong OS X bootloader was in use – specifically, a bootloader from an older version of OS X.  Is there any chance of that happening there?

           

          Cheers,

            Hey Darius,

             

            Nope, it was a clean 10.10 DP1 build, then upgraded to 2,3 and 4 - this happened at 4.

             

            Even with that though, isn't that incorrect advice?  I though that OSX always expected 2 cores and having less could cause it to hang.

             

            I'm somewhat stuck troubleshooting at the moment - the VM barely runs due to the 'stuck on writing' vmware tools bug, but will do what I can.

              I've gone through and checked all my VMWare Fusion 6.0.4 Mac OS X guests, and they are all set to two cores. It would indeed seem contradictory, as in Fusion 6.0.4, changing cores to one results in a warning.

              Yes, I realise this is the TP2014 that you're discussing, but I would imagine the same core requirement would be applicable in the TP, as per VMWare Fusion 6.x.x.

                Yes, the advice to use only one virtual processor core is incorrect.  I'm saying that the conditions which cause the advice to appear should not be happening.  We'll need to dig into it to determine why that message appears.

                 

                Recent versions of OS X definitely require at least two cores to operate reliably.  That's the warning you see on the Processors & Memory pane when you configure the VM for only one core.

                 

                Under certain conditions, some very old versions of OS X might run unreliably when they are running on more than one core.  The incorrect advice appears because we somehow think you are running an older version of OS X, and we attempt to fix the problem which could cause the old version of OS X to run unreliably.  Usually we silently fix the problem, but here we are incorrectly reporting that we fail to fix it, because it is not actually an old version of OS X at all.

                 

                Ignore the "Your Mac OS guest might run unreliably with more than one virtual core" advice... it should not be appearing.

                 

                Thanks for the report.  I'll get back to you if I need more information.

                 

                Cheers,

                  You bet - that's why we have betas :-)

                    What is the value of guestOS in your .vmx config file?

                      Hi plasticphyte,

                       

                      Just wondering whether you have also encountered this warning there.  Your post doesn't say one way or the other, and I'm not sure whether I should count your post as another sighting of this issue or just a helpful comment from a fellow Tech Previewer. 

                       

                      Thanks!

                        Was mostly a helpful comment. I've not run into the error yet, but will keep an eye out for it.

                          I've nailed it down to occurring after the initial install of DP4, during the reboot, before the second half of the install continues - and only if you started installing from DP1 and updated the rest of the way via software update.

                            This issue has been fixed internally. Until we release bits with the fix, the workaround is to click on "Continue".

                             

                            Thanks for another great report, dlhotka!
