I know that running a developer beta isn't supported and I assume the risks... yada, yada. I just wanted to point out that Parallels 11.1.1 (32312) will not install or run in the El Capitan 10.11.3 beta. The previous version of Parallels 11 was running fine in 10.11.3, but I got the update alert for Parallels so I went ahead and installed it. Now, the installation is corrupt. The application is zero-k and has the icon with the circle/slash through it. The error is ' You can't open the application "Parallels Desktop" because it may be damaged or incomplete'. I tried completely removing it and all related files before reinstalling, disabling SIP, making sure apps are allowed from anywhere in security prefs but nothing works. I'll hold off for the official release of 10.11.3 and hopefully an update to Parallels.
