Since installing Lion, I've had Safari 5.1 become unresponsive to input several times on two different machines (both iMacs, in different locations).

I don't see anything in the forums I quickly checked. Any ideas?

(Safari becomes responsive again after quitting and restarting. Input device -- mouse, trackpad -- makes no difference.)

This problem effects newer Macs as well. I have a brand new MacBook Pro and experience random text input freezes when using safari. MacBook Pro 8,2 Safari 5.1.2, OS X 10.7.2, 8 gb RAM, 2.5 gHz i7, – user18550 Feb 10 '12 at 18:41

Try completely clearing out Safari of junk.

First, empty the cache by hitting Safari > Empty Cache....

empty cache

Click Empty.

are you sure

Then completely reset Safari by hitting Safari > Reset Safari.


Check all the checks and hit Reset.

sure reset

Then quit and relaunch Safari. That should speed things up.

If not, you can always use another browser. ^cough^Chrome^cough^

Trying this now. Thanks for the suggestions. – howardweaver Aug 11 '11 at 3:33

Has nothing to do with resetting anything or emptying any cache. Ignorance of mouse clicks is a Mac OS X 10.7 bug which seems to occur on older Macs and should be addressed by Apple.

Might you have a radar number to track this bug? – bmike Nov 14 '12 at 22:28
