    I just got a new Macbook Pro M4 Max. With the new computer I am unable to run my virtual machine or set up a new one. I get.. "The specified configuration file is invalid."
    On my M1 Air Parallels Desktop 18 has been running on Sequoia with no problem.
    Why is this?

    I believe Parallels is doing this on purpose. The VM was clearly working under Sequoia with v18, only now with the new installation it won't run. They're probably blocking the software in order to make people go and upgrade

    Hello,
    As per the Parallels Desktop and macOS compatibility guidelines , Parallels Desktop 18 is not fully optimized or compatible with macOS Sequoia, which can cause stability and performance issues, including the inability to start your virtual machine.
    Parallels Desktop 20 has been developed to be fully optimised and compatible with host macOS Sequoia.
    To resolve these issues, we would recommend you upgrading to Parallels Desktop 20.
    Thank you.
