"spinning wheel ON SAFARI" için yanıtA lot of the solutions are from long ago. Here’s an update with a more recent Mac system. Problem: The spinning wheel would show up about every 15-30 secs and Safari would stall for about 5 sec. I cruised lots of forums and there were lots of suggestions. The three steps that solved it for me were: 1. Clear Safari history. 2. Trash the preferences file "com.apple.Safari.plist", located at: HD > (your user account) > Library > Preferences. Restart Safari. 3. Run Disk Utility, “Repair Permissions”. iMac 27", OS 10.9, Safari 9, 1. 1 TB.
