I'm currently running the trial upgrade of Parallels 9 and upgraded my MBP to Mavericks. I use the VM for all my docs word, excel & power-point as I migrated all my work onto my MBP. I utilize the mac for Mail, contacts & Calender. This was working fairly well ( the occasional hang with parallels when trying to shut down the computer). But since the upgrade some items are not working as well as they did. For example I have been using Snipping tool to take partial screen shots and now it won't work. Items saved short term on the desktop for ease and then moved across to the relevant file move but also stay on the desktop? And my canon printer had to be reloaded! Has anyone else experienced any issues? Talk to apple and mention parallels and its a parallels issue and i found parallels customer support to be almost nonexistent in my previous dealings with them.
