As far as I am aware, there are no solutions. OS X 10.11 has not yet been publicly released, and Symantec policy is that we do not support beta builds of an OS, so 10.11.1 is likely a ways behind.
When Apple changes the way OS X operates, we have to recode. This is part of why you see limited versions of Encryption Desktop supporting limited versions of OS X, whereas you can use PGP Desktop version 10.0 on a Windows 7 system. Windows does not make a lot of fundamental changes to the system.
Simply put, it is not a supported configuration, and you will have to wait until such time as a supported version for OS X 10.11.1 is released. We don't have any information on engineering and/or their progress that we can share at this time.
