Again I did it! I bit the bullet and updated Parallels to it's newest version. Now my Windows 10 virtual machine is/feels ten times slower than before the update. Also the Os X feels sluggish. Even the Windows is just idling, Os X shows 100 - 200% load for cpu. I should be able to work tomorrow, now I can't, and I can't take this anymore. On my Mid-2015 Macbook pro I have given Windows 8/16 Gb of memory and 4/8 cores. This worked beautifully today before the update. It seems that every third update for Parallels this same kind of sh*t! Is it possible to download earlier versions somewhere? Or do I have to switch to VirtualBox or VMware? I feel sick inside.
