I have the latest versions of * MacOS Mojave * Windows 8 * Parallels Home 14 * Quicken 2019 Premier Windows Hardware is a new (2017 model) iMac 27" machine. I frequently use Quicken Windows from within a Parallels virtual machine. After recently upgrading my hardware and MacOS, I am getting crash/reboots of MacOS more than once per day. Most of the time, I am doing something with Quicken: launching it, starting a download of financial data, and so forth. Just today, I got a MacOS crash while shutting down Windows virtual machine. So Quicken use can cause the crash, but it is not the only cause. Any suggestions?
