Q: Safari locking up ?

Hello,

 

I have recently upgraded to macOS Sierra

Upgrade went fine.

However I notice that Safari web browser does lock up now from time to time.

It becomes unresponsive and I have to restart the app.

 

How can I fix this?

I have allot of bookmarks, could this be causing the problem?

Should I delete my bookmarks and start new?

Where is the bookmark file so I can delete all the bookmarks?

How can I clear the cache for Safari ?

Can I increase the cache for Safari?

How can I remove plugins for Safari ?

I already disabled bookmark syncing in iCloud setting.

 

-Thanks

MacBook Pro, macOS Sierra (10.12), Mid-2012, 13", 16gb ram, 500gb. SSD

A:

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items.  Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library./Caches/com.apple.Safari/Cache.db and move it to the trash.

 

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

For plug-ins, Safari/Preferences/Security and uncheck Allow plug-ins.

    I've had a similar issue with sites with auto-play videos (usually Flash content). I opened a terminal window and ran 'top'. There was a process that was taking 100% of the CPU. Due to the terminal window size I could only see "com.apple.Sa" as the process name. I killed that process and the browser returned to normal. Now I only know enough to be dangerous, and I can't figure out what the process really is, but it seems safe to kill. Someone with a better knowledge of Unix could probably figure out what it is. Since I don't know, I haven't opened a bug report. Finance.yahoo.com and cnn.com with their videos usually are my culprits.
