Mac OS X
Q: New update 10.11.4 issues: Sys Prefs will not load.
After the install I attempted to load Contacts and none of the Groups were avail. In Prefs I clicked on iCloud and immediate error posed up "Preference Error; Could not load iCloud preference pane." The same error for Users & Groups; Mission Control; Internet Accounts; and more. But approximately 30 minutes later while writing this the above prefs appear to be working.
Gish..I thought it was going to be another "PHOTOS" blunder!
But so far it is working.
