Fusion 13.6.4 issues with macOS Tahoe

  • 1.  Fusion 13.6.4 issues with macOS Tahoe

    Posted Sep 17, 2025 09:39 AM

    Fusion seems to be impacted be a serious bug in relation to Tahoe and sleep. 

    When my host MBP goes to sleep with Fusion running a Windows 11 ARM guest, on waking from sleep the whole Fusion app seems to be degraded. I am unable to view any Fusion window, including the VM Library or the guest. The guest is still running, as far as I can tell, but its window is not visible any more within macOS. 

    Quitting the Fusion app and restarting it doesn't solve the problem. On restart, Fusion will then display its VM Library window but doesn't seem to be able to reconnect with the still running guest, nor control it.

    Shutting down the host clears the issue, obviously. Another less inconvenient workaround is to quite the Fusion app and then search for 'vm' in the Activity Monitor to find the guest virtual machine, and then quit that. After this Fusion can be restarted, the guest rebooted, and operation resumes.

    Obviously killing the guest vm like this is far from ideal.

    This bug makes working in Fusion almost impossible. If I walk away from my machine for any time, I need to suspect/shutdown the guest before walking away, in case my MBP goes to sleep.

    I wonder if this is new behavior with Tahoe or some old behavior that may or may not be getting worse.

    There have been reports of Fusion having issues with the host sleeping while VMs are running. See https://community.broadcom.com/vmware-cloud-foundation/communities/community-home/digestviewer/viewthread?MessageKey=e0e689a0-d2bf-4a6f-9d7e-ddd348e527e0&CommunityKey=0c3a2021-5113-4ad1-af9e-018f5da40bc0

    Hi Paul,

    Interesting and in the very far past I have seen sleep related issues too, but nothing like this, and I believe the symptom to be different.

    I’ll keep monitoring my setup. I am running with the MBP plugged into an external display - an Apple Studio Display - and it may be that this is in some way part of the mix. I say that because I have had issues in the past with sleeping which only occur when an external display is present and the MBP running in clamshell mode. That configuration seems to be a bit of an achilles heel for Fusion.

    It seems to be very repeatable. I’ve had this problem occur three times today before posting.

    I've been able to reproduce this. I think I have a workaround that doesn't depend on manually killing the vmx process or rebooting. It involves using the vmrun command to identify and suspend the VM. Then you should be able to fire up the Fusion GUI and resume the VM.

    I was able to get around this. I'll post more details when I'm able.

    You may want to hold off upgrading to Tahoe - especially if you have a Mac Studio M3 Ultra. Howard Oakley over at the Eclectic Light Company blog is reporting an incompatibility with Tahoe and these Macs. See https://eclecticlight.co/2025/09/17/macos-26-0-tahoe-build-25a354-is-incompatible-with-mac-studio-m3-ultra/ for more info.

    I’ve seen similar complaints in MacRumors. My MBP M4 Max is working fine with Tahoe. Just Fusion that’s struggling.

    Seems this is only an issue for M3 Ultras that have first been updated to macOs 15.7 prior to attempting the Tahoe install. If you skip 15.7 you're good.

    Sorry for the delay in my response to this.

    I've been able to reproduce this when the VM is running in full screen mode. I've not been able to reproduce it when running the VM in single window mode.

    It's a curious bug from what I see. When the VM is running in full screen mode and the Mac sleeps, the VMware Fusion GUI app has quit. But as @Bigdave1357 says, the virtual machine is still running.

    See if the following helps get the VM back without having to reboot or kill the vmx process:

    1. Verify that the VM is running by using the following command vmrun -T fusion list You should see the command report that the VM is still running and shows the path to the .vmx file. Example: :
      % vmrun -T fusion list
      Total running VMs: 1
      /Volumes/Virtual Machines/Windows 11 ARM 25H2 preview.vmwarevm/Win 11 ARM.vmx

    2. Issue the following command to suspend the running VM: vmrun -T fusion suspend "path-to-vmx-file"

      The path-to-vmx-file argument is the one that was returned by the vmrun list command, and should be enclosed in double-quotes as it likely has spaces in the path name. You will need to provide the VM's encryption password when prompted.
      Here's an example:
      vmrun -T fusion suspend  "/Volumes/Virtual Machines/Windows 11 ARM 25H2 preview.vmwarevm/Win 11 ARM.vmx" 
      Encrypted virtual machine password: 
      %
      Note that you don't get a prompt that anything happened. Re-run the command in step 1 to verify that the VM has indeed suspended.
    3. Now start VMware Fusion. You may be prompted for the password of your Windows VM. Provide it if asked.
    4. You should now see the VM's full screen window appear. You should be able to resume the VM from this point by clicking in the window.

    I wonder if the issue appears because the Fusion GUI is terminated by something during the sleep process, and that termination may be related to managing the VM in full screen mode.

    I can confirm that this works on my setup.

    The bug can be replicated very easily: fire up a VM and then use the Apple Menu-> Sleep command to immediately sleep your machine.

    Give it a few seconds to ensure the sleep has really taken effect and everything has shutdown.

    Then move the mouse to wake up and you’ll find that the bug has bitten: the Fusion app has either quietly crashed or just shutdown, orphaning the running vm. Starting Fusion won’t rediscover the vm.

    Follow Paul’s steps and the VM will suspend. Restart Fusion and then it will find the vm and you can resume work.

    My vm’s are all encrypted, so the password is needed to do this. My passwords are long and complex so I keep them in the keychain.

    It’s a PITA to dig them out and go through the steps to recover the VM. Quicker to simply kill the vm and go again, although that is certainly not recommended.

    So you have three workarounds:

    1. Kill the orphaned vm. Quick, but NOT recommended.
    2. Use Paul’s method. You could put together a script or automation to make this more easy. You could even include the password if necessary, but that would mean disclosing it in plain text, which isn’t ideal.
    3. Reboot your machine.

    There’s another way: just don’t walk away from your machine with VM’s running, or configure your host machine not to sleep. Neither are particularly good options either, but something you can consider.

    Hopefully Broadcom will class this as a high priority problem and issue a hot fix. It makes the whole Fusion app very difficult to use.

    My thoughts are that either this only showed up in the release version of the app (highly unlikely in my opinion) or Broadcom did not properly test or test at all using the many betas released by Apple. If it’s the former, then I guess we’re all just really unlucky. If it’s the latter, I for one am really disappointed in Broadcom.

    Redeem yourself by issuing a hot fix, and quickly.

    Thanks for the workaround, Paul. No doubt it will help many people.

    Yes, killing the process will work, but my concerns are that unclean termination of the vmware-vmx process could result in other bad behavior. I'd rather err on the side of caution to not introduce a possibility of a corrupted VM.

    Remember that technically macOS Tahoe hasn't been listed as qualified as a supported host operating system or Fusion. This isn't the first time a macOS upgrade has broken something with Fusion that required VMware/Broadcom to update Fusion to handle.  Broadcom, like VMware before it, is very tight lipped on future product releases. It's difficult to say when they will release something that will address this bug.

    This being said, I have started to ask about this through some moderator back-channels. I'm trying to make sure that the product team knows about this and maybe  -- just maybe -- get some kind of response. At least I hope we can get "we know about it and have notified the product developers". I'll let everyone know how that turns out...

    There is no other place to report Fusion bugs other than this forum. We can only hope that Broadcom will take note of bugs reported here and fix them in future versions of the product  

    Again, remember that Fusion running on Tahoe is an unqualified/untested configuration (I hate to use the term "unsupported" because Broadcom no longer provides technical support for Fusion). Since it hasn't been subjected to any official testing, it's likely that problems exist on Tahoe that weren't seen on Sequoia.

    Thanks Paul, for your efforts on this. Hopefully your back-channel will prove fruitful.

    i think this might be the final straw for me if Broadcom don't recognise the severity of this situation and produce a quick fix. I've been with vmware products for years and I will be sad to go but as a business user I need tools that i can depend on. So far I have stuck with Fusion despite all the recent corporate changes but I really can now feel that I am using unsupported software.

    We should not expect Broadcom to test Fusion in advance of new OS releases nor produce rapid bug fixes, or even fixes at all, if the product is unsupported, which seems to effectively be the case. But I do have that need so I guess I'm using the wrong product. A well known competitor product has full compatibility with Tahoe and full support. It's a paid product but then I was always a paying customer of Fusion. 

    I'll give it a few more days and see what transpires, but it might be time to pull the trigger.

    From what I remember as a long time Fusion user, VMware rarely had "day-one" support for a new macOS major version.

    It's a fair point, though, that many software vendors work with beta versions in order to announce that day one support.  But that does not guarantee that the shipping product is free of bugs on the new macOS version. The industry is littered with software that worked fine in beta versions that suddenly stoped working in the released version due to last minute changes.

    broadcom's shift to making the desktop hypervisor products free of charge is a both good and bad for us  Yes, we no longer have to pay for Fusion.. But with no revenue for Fusion, it brings into question how much resource they're going to allocate to provide timely attention to the product. I for one would like the option to purchase support (open source vendors seem to have figured this out - free license, paid support) for the product to fund development and more timely bug fixes  

    An audio proceinng utility I use just released their Tahoe-compatible update. It's not bug free though -  they list 2 known annoying bugs (with workarounds) impacting their product that they've reported to Apple and are awaiting fixes.

    My guess is that you won't see any update in "a few more days". It's also entirely possible that this is an Apple problem introduced in Tahoe as this did not happen in Sequoia.  In which case, we could be looking at an Apple fix  

    if one depends on any computer system for a living, it may be a good idea to wait until the software you use announces support for Tahoe. Early adopters always risk having problems.

    Good points, as always.

    However, business pressures, particularly in development, don’t always allow for developers to hold off using new versions of software. I for one work an in an environment where complex toolchain dependencies mean that I’m more or less forced to update to newer versions of code within a few days of them being publish. The knock-on effect of not doing this can lead to other issues with other toolchains.

    I think the main issue here is that the Fusion products is not receiving anything like the support, if any, that it should for it to be considered “business class”. Like you I would pay for a supported product, and did in the past. But that’s not on offer. So if nothing materialises in the short term from Broadcom, I think it will be goodnight from me, and hello to Parallels.

    To me the best option would be to restore back to the previous OS. Tahoe is new and untested in the field. There are probably lots of apps that don't work properly. In a business situation I would never upgrade an OS to a new version for at least a year unless there was a very compelling reason to do so and even then I keep a partition of the old system on the computer. I only just upgraded to Sonoma which is two versions behind as I have programmes that won't work on Sequoia and Apple provides security updates two versions behind.

    Or just use a Hypervisor that’s supported and updated frequently. Like Fusion used to be. Honestly, whilst these are good points, I think we’re now at the stage where we’re making excuses for Broadcom and I’m not going to continue doing that.

    I am a long long time user of both Mac and Windows versions of VMware products. I just recently decided that with no support, a move to Windows 11 and macOS Tahoe, and Broadcom doing their usual 'strip out the value then kill it' I needed to move. Virtualbox is getting better and if Oracle throws some $$$ at it, it will be a great product. For now I will look at Docker (yes ir runs on Mac desktop) or migrate to Parallels and pay the subscription. VMware gives me no alternative. There is no source available and no hope of ever getting any serious bugs fixed. Apple is making significant changes in their VM support frameworks and one of these days VMware will stop working. I prefer to be out of the building before the roof falls in. Last one out turn off the lights.

    That's good news @drbill It's the same as what I saw when running the Insider Release Preview build of Windows 11 25H2.

    What build of Windows were you running before moving to 25H2? What I found (and what Microsoft has been saying) is that in-place upgrades from 24H2 to 25H2 was fairly quick since Microsoft is using a enabler package (like they did in the 22H2 > 23H2 "upgrade:). The enabler package simply "turns on" dormant 25H2 features that were already released in prior 24H2 updates. Could your slow upgrade be due to using an ISO to upgrade instead of using an enabler package?

    Citrix within Ubuntu in Fusion is also not working properly.  I've tried bridged and NAT network modes.

    Brian, can you provide more details about what's not working with Citrix and Ubuntu?

    Intel Mac? What model?

    version of Fusion?

    Version of Ubuntu and Citrix (I assume this is Citrix Workspace you are running on Ubuntu)?

    Was this working prior to the Tahoe upgrade?

    Have you tried running Citrix Workspace on the host Mac instead of in a Virtual machine?

    Hi Paul,

    I’ve been monitoring the original bug report for a while now and I can confirm that it doesn’t seem to occur when my MBP is running standalone - i.e. without a display connected.

    The bug bites, at least for me, only when I have the laptop lid closed running in clamshell mode, connected to an external display, in my case an Apple Studio Display.

    Macbook M4

    Fusion 13.6.5

    Ubuntu 22.04.5 with latest Citrix running with Global Protect VPN.

    This was working with last Mac OS prior to Tahoe. It stopped working immediately after updating to Tahoe. The website I need to access to launch the Citrix app fails to load (times out).

    I cannot run Citrix directly in Mac OS because VPN via MacOS is not supported by my company.

    Is your Ubuntu VM getting a network connection activated? I had a Ubuntu VM that failed to connect to the network after the macOS upgrade. I had to reset Fusion's dhcp lease file found in /var/db/vmware to get that VM working again (I suspect that my problem may have been related to customizations I had made to the dhcpd.conf file for vmnet8 though.

    It seems to have an Internet connection. I can reach other websites such as YouTube. I’m wondering if a certain port is being blocked or not forwarded correctly. I have tried both NAT and bridged networking modes.

    Just a suggestions that will not work for many because of work environments and security concerns but, until this is fixed, maybe set a hot corner to disable screen saver which should prevent the computer from going to sleep if one walks away for a little while.

    I would think that the safer alternative (especially if you depend on your Mac for a living or for work) is to stay on Sequoia until Broadcom releases a version of Fusion that's qualified for running on Tahoe. 

    No work environment that I've been associated with in a long IT career would allow the upgrade to a major new operating system version until a lot of due-diligence is performed. That includes verification that third-party applications in use are qualified by their developer(s) to run on those new versions. 

    I'm beginning to sound like a broken record (and I'm sorry about this), but at the present time, you run 13.6.4 and earlier versions of Fusion on Tahoe at your own risk. You should be willing to accept that unqualified software combinations may have issues and you'll have to deal with them until Broadcom releases an officially qualified version of Fusion for Tahoe.

    We were mandated to update to Tahoe already - so this bug is currently biting me very frequently.

    At least the reset instructions help get it going again without reboot.

    I do have an external monitor plugged in for dual screening alongside laptop screen - and it doesn't happen every day, I think it only applies if for some reason laptop briefly wakes during night and activates external monitor.

    This is not just a Tahoe issue. I got the same problems sine I started using Fusion a couple of OS releases ago

    Hello, I have been watching this thread as I have one use case which requires windows 11 and am using VMWare Fusion for that workload. I noticed today a new release 25H2, but I don't see any release notes with it. Has that solved the MacOS Tahoe issues?

    -------------------------------------------



  • 36.  RE: Fusion 13.6.4 issues with macOS Tahoe

    Yes, it looks like Broadcom has released a new major version of Fusion. I'll have more on it in a short while -- I'm in the process of posting links to the announcement and release notes.

    The one thing I saw is that Fusion 25H2 now lists Tahoe has a supported host operating system. Whether that fixes the bug that orphans virtual machines is yet to be determined. Stay tuned.

    I just installed Fusion 25H2 on Tahoe. I'm unable to reproduce the orphaned VM issue when forcing my Mac mini into sleep with a VM running in full screen mode. It might be worth a try to upgrade Fusion to 25H2 if you're running on Tahoe and are experiencing this issue.

    Thank you for testing that out.

    25H2 seems to fix it for me. I could reproduce this bug with 100% repeatability: simply choose Apple -> Sleep from the menu bar. On waking, Fusion would have crashed (Seg. fault) leaving any running guests orphaned.

    Having installed 25H2 and repeated the test several times, I can report zero fails. I'll continue to monitor in case other routes to sleep, through different power save states, still trigger the bug, but I would say it's looking very positive.

    Thanks VMware. This was really hampering my usage of the product.

    25h2 seems to have fixed the primary root issue - today I did not wake up to a hung VM, but it did reset resolution to 1024x768 - I have an external monitor.
