Safari has become very slow to load pages. 5 to 10 seconds to begin to display a page. The problem is isolated to Safari on this computer. Other systems and browser are ok.
The system is a 13" Early 2011 MacBook Pro running El Capitan 10.11.6. I have done all of the stuff I would normally do to diagnose as problem: run Disk Utilities, purge caches, check permissions, login via a clean user account, etc.
In Console.app I notice that the system.log is getting filled constant stream of with messages from launchd related to Safari. Most of these are related to
9/22/16 6:30:28.428 PM com.apple.xpc.launchd: (com.apple.xpc.launchd. domain.pid.WebContent.2063) Path not allowed in target domain: type = pid, path = /System/Library/StagedFrameworks/Safari/SafariShared.framework/ Versions/A/XPCServices/com.apple.Safari.WebFeedParser.xpc/Contents/ MacOS/com.apple.Safari.WebFeedParser error = 147: The specified service did not ship in the requestor's bundle, origin = /System/Library/ StagedFrameworks/Safari/WebKit.framework/Versions/A/XPCServices/ com.apple.WebKit.WebContent.xpc
To a lesser extent there are also ones related to
9/22/16 6:03:05.314 PM com.apple.xpc.launchd: (com.apple.xpc.launchd. domain.pid.ImageDecoder.1379) Path not allowed in target domain: type = pid, path = /System/Library/StagedFrameworks/Safari/SafariShared.framework/ Versions/A/XPCServices/com.apple.Safari.History.xpc/Contents/MacOS/com. apple.Safari.History error = 147: The specified service did not ship in the requestor's bundle, origin = /System/Library/StagedFrameworks/Safari/ SafariShared.framework/Versions/A/XPCServices/com.apple.Safari.ImageDecoder.xpc
Any ideas of why these are getting through into the
system.log, if they are related to Safari's slowness, and how to fix.
