I have a new iMac with Mac OS X 10.11. for run Caldera 9.2 plotter program, i installed Parallels Desktop Version 10.3.0 (29227) and Mac OS X 10.9 (Maverick). Caldera is compatible with 10.9, not with 10.10 or 10.11. But 10.9 don't recognised USB port and sound of the iMac. Is Parallels 10 compatible with new iMac and MacOS X 10.11 ? Thanks Xavier (of France)
