    Hello- I am having a lot of issues updating a Parallels image from Sequoia to Tahoe, after all 'upgrade' related updates continually failed, I used a stand-alone Tahoe installer which DID install the operating system, which boots up, but that is when a whole lot of lag and failure begins.
    -Apps don't open
    -Parallels Tools fails to update
    -Keyboard stops functioning appropriately
    -Ultimately the instance will freeze shortly after this and I will have to issue a 'stop' command to try again.

    I have updated memory, graphics resources, and have had no luck. Thank you for your help!
