I have an iMac and use a trackpad. But I got to try Pararells Desktop because of tax app that work only with Windows. Got trial but I remove it after 4 days. I wanted to retry in trying to solve the rackpad issue, Trackpad scrolling speed in the app wast terrible, but Pararells Desktop trial was end. I have tried with different account but did not work, seem parallels track the IP address. This is really unfortunate because I need to buy but it did not allow me to try to solve the problem first.
