    Mac OS Catalina (Beta) - CPU Heating Issue

    SteveLup Novice

      Hi

       

      I noticed my fans were spinning constantly whenever using Fusion after installing Catalina and have narrowed it down to some rather curious behaviour.

       

      Using Intel Power Gadget to monitor CPU power / clock speed etc, the following strange behaviour is evident:-

       

      Basically, as soon as I open the VMware GUI (with no VMs running, nothing at all), instantly the core frequency of the CPU hits max and gets pegged there. CPU power consumption goes up from sub 10W to > 45W, the temperature rapidly rises and the fans end up running full speed.


      This is with -zero- actual CPU usage. The Core Utilization is < 5% and nothing of interest shows up in the Apple Activity Monitor. Close the VMware window and instantly, core frequency drops back down to something sane and the temperature immediately starts backing off.

       

      Very odd...

          Cab you see which specific process is consuming all the CPU?

          ('VMware Fusion', vmware-vmx, 'VMware Application Menu'...?)

            No CPU is being used at all - none.

             

            All that is happening is that the CPU core speed gets set to max despite their being no load.

              The section in the middle is with the Fusion GUI open.

               

              I have very closely looked at the CPU usage when in this state. The various VMware processes are all each under 1%. The only notable thing is that whenever the Fusion GUI is open, coreaudiod sits there at a steady 4% CPU usage, and drops back down to sub 1% when Fusion is closed. The total CPU usage delta between Fusion open and closed is 6% - which in no way should account for the CPU clock instantly scaling from sub 1GHz to 3.5GHz.

               

              It's very odd.

                Hi Steve, Did you ever find a solution to this? I am running into exactly the same problem.

                  In Activity Monitor, check the process "vmrest". Does the PID of this process keep changing?

                  If so, open Preferences window in Fusion, select "Never" in the combobox under "Applications menu: Show in menu bar:". It will disable Applications Menu.

                    That worked. No issues any longer.

                      I can confirm that solves the problem for me too, thanks.

                       

                      Apologies for not responding sooner.

                       

                      I don't know if VMware monitor this community - does this need formally reporting somewhere?

                        Hi,

                         

                        VMware forum user Zhus is an employee of VMware, so I think they know about the issue.

                          Steve, I am trying to make a MAC OS (Mojave) virtual machine but keep getting errors.

                          I down loaded Mojave from the app store and according to what I read I should be able to use that app to create a VM,

                          It does create a VM but when I try to run it I get three errors.

                           

                          Any thoughts?

                            Sorry, I don’t run MacOS VMs so can’t offer any advice.

                             

                            Your question isn’t related to mine in any way - you’d be better off creating a new topic as people who may be able to help you might miss this.

                              As soon as I set the Applications Menu to "Never", the fan went silent.  This fixed my issue. Thank you for your help.

                                I have done all tips, but my CPU still consumes over 100% power.

                                After added the following to your VMs vmx file:

                                mks.enableMTLRenderer = "FALSE" 
                                mks.enableGLRenderer = "TRUE"

                                my VM doesn't work - dictionary problem.

                                 

                                disable the application menu: Preferences -> General -> Applications menu: show in menu bar -> Never - nothing changes

                                 

                                What is more in my case i have the same problem with carlos3000

                                sudo find "`getconf DARWIN_USER_CACHE_DIR`" -name com.apple.metal -print0 | xargs -0 rm -r:

                                find: /var/folders/s4/t0520nsn6kq1mq_g4w5vgppr0000gn/C//com.apple.WebKit.WebContent.Sandbox: Operation not permitted

                                My VMware version is: Professional 11.5.1 (15018442)

                                MacBookPro:

                                Intel Core i7 3,5GHz

                                RAM: 16GB

                                OS: Catalina 10.15.2

                                 

                                Please for our help!

                                  Hi,

                                   

                                  A dictionary problem means that you added illegal characters to your .vmx file by editing it.

                                   

                                  Most common problem is having smart quotes enabled in TextEdit, see menu -> File -> Preferences in order to change that and uncheck the settings.

                                   

                                  Also note that you should type and not copy & paste those values from the internet as the same or similar problem might have occured.

                                   

                                  If you're unable to fix it, then attach both the .vmx and a recent vmware.log to a reply here.

                                   

                                  PS: What MBP are you using? (intel i7 doesn't tell me from what year it is, it could be from 2009 to 2019..)

                                   

                                  Moderate note:

                                  Please do not reply the same answer to different threads. It is not going to get you an answer faster, it just makes it difficult for others to follow your problem and the possible resolutions.

                                  I have removed your other copies, so that the discussion stays in this thread.

                                    Sorry, for my multithreaded pposts. This is my first post on the forum and a few threads suited my problem. Thank you for your understanding and response.

                                    Dictionary Problem has been partially resolved. Because in Windows VM launched after the entry in the .vmx file:
                                    mks.enableMTLRenderer = "FALSE"
                                    mks.enableGLRenderer = "TRUE"
                                    however, it still doesn't solve the CPU consumption problem (over 200%)
                                    For Linux, VM now displays "VMX file is corrupt". When I wiped the entries I can VM Linux start again.

                                     

                                    My MBP is a 2017 model.

                                    I attach both relevant files below.
