I'm using Parallels Desktop 13.3.1 (43365) for Mac. This version was meant to fix the Parallels Tools not installing on Kali problem but it hasn't. Using Kali 2018.2 and trying to install Parallels Tools gives an error saying that linux-headers-4.15.0-kali2-amd64 and printer-driver-postscript-hp are not installed and to install them manually. After doing a system update after installing Kali I already had linux-headers-4.15.0-kali3-amd64 and printer-driver-postscript-hp version 3.17.10+repack0-5) installed. I am not going to downgrade packages just to try to get Parallels working. I'm going back to VirtualBox which works great and is free.
