Parallels has thankfully extended the life of our Mac only accounting software for our ad agency after Catalina forced 25 years of smooth AccountEdge software to no longer make a transition to a Catalina version after months of adjusting their engineering to new Apple requirements. So AccountEdge moved on to PC servers and Cloud only options we looked at several versions of software for extreme cost increases. Parallels saved the day and I installed Mojave and am running AccountEdge with no issues as always before. This may extend the life of our accounting software for years, especially at a time it took 2 months to resolve several other complications from the 149 other Applications when forced to a new Catalina system. Kudos to Parallels for such great help in making things simple.
