I just got a Mac Mini 2.6 with the Fusion drive, running Mavericks and down loaded Vienna Symphonic Instruments VE Pro 5 demo. When I attempt to start the Vienna Ensemble Pro Server software, 32-bit or 64-bit on the MacMini it immediately crashes. I moved the eLicenser dongle to my iMac that is still running Mountain Lion and it loads with no issues. I posted the issue on the VSL forum and they said VE Pro 5 is totally compatible with Mavericks. I repaired disk permissions and reset the PRAM on the Mac Mini but the VE Pro Server software is still crashing. Is anyone using this software with Mavericks with success?
