    After installing macOS Tahoe (macOS 26) Dev Beta 1, the VM can no longer connect to the internet and an error message attached pops up when attempting to run the VM. I understand that it was just released as of this afternoon, but I would like to see if maybe this can be addressed. I tried reinstalling Parallels Tools and restarted the machine, and it still won't connect.

    I fixed it: I removed the Network in Parallel's Option panel of the VM (Hardware tab) and I added it again.
    Upon starting the VM, the network is working fine.

    I have the same issue on my MacBook M4 Pro, and it's still unresolved, but I had no issue on my MacBook M1 Pro Max. Hopefully a fix will be released soon :)

    What Parallels version are you using? P19 or P20?

    Hello,
    Can you please confirm if the issue is only affecting existing virtual machines after updating to Tahoe, or if the issue is also observed on virtual machines that are created after having upgraded to Tahoe?

    Can you please collect and send a technical report when the issue is observed:

    Click Parallels desktop icon on the top-right side of your Mac screen > Help > Send technical data > check "Attach screenshots..." > press Send Report and send the report's 9-digit ID in a reply to this thread.

    More details on how to collect a report can be found in this article: https://kb.parallels.com/en/9058

    Regards,
    Parallels Team
