I installed Parallels 11 and have both win 7 and 11 installed. The windows itself run pretty good. My problem is on boot. The initial start into just Parallels 11 without loading any VM. it can tale 5-10 minutes at startup for Parallels to load (this is on fresh boot or restart of the IMac. This is with "El Capitan". My MBP with El Capitan and Parallels 10 windows 7 runs like a dream. Any one else have a real slow Parallels 11 boot? Any suggestions. Thank You!
