Unable to Install OS X El Capitan FileVault conversion in progress
I am trying to upgrade to El Capitan and a message pops up saying the following:
FileVault conversion in progress.
Use the "Security and Privacy" preference pane to check conversion status.
I had this problem from Yosemite since I bought a new MacBook Pro and left the default value for an encrypted volume on.
I have tried every solution I could find without being able to solve the problem or downgrade to an unencrypted version without sucess.
I could use your help as this issue now affect my ability to install the new MacOS.
Thanks in advance.
MacBook Pro with Retina display, OS X Yosemite (10.10.5), 15-inch, Mid 2014
