OK, I have an old iMac (2010) that just won't die and it has basically become a gaming machine. I play old versions of Warhammer 40k and Warcraft on it through Parallels Desktop v17. The iMac is running High Sierra. Everything works fine. My wife gave me her iMac, a 27" late 2015 running Monterey and PD 18. I copied the VM over from my old machine and tried to play Warhammer (just as a perfromance text 8) ). However, when the game starts in full screen, I can't see the mouse icon. I'm using an apple blue tooth keyboard and magic mouse. Any hints or suggestions about why mouse behaviour might be changing? cheers, dpc
