Very Slow since El Capitan

Can take over a minute of beach ball spinning just to move from one document (text) to another, and well over 2 minutes for a manual save. Cannot get anything done!

Any ideas would be appreciated.

It could likely be that your Mac address book has issues. We don’t know the nature of those problems, but those experiencing these kinds of slowdowns can speed up Scrivener greatly by disabling its access to the address book system, using the Security & Privacy system preference pane, under the “Privacy” tab. Within that section, click on “Contacts” and then disable Scrivener’s access (you will need to restart Scrivener, if necessary, after doing so).

That seems to have done the trick. Thanks very much.
