The "click" on my MacBook Pro has started having problems. I haven't been able to find a root cause on the problem yet. It doesn't work on either my magic trackpad or the internal trackpad.
I have OSX 10.6.7 on a Spring 2010 17" MBP.
I have booted in safe mode to rebuild the driver cache. Everything works ok when I restart. But the click stops working eventually.
I have booted in single user mode and ran applejack. Again everything works ok when I restart. But, eventually the click stops working.
Since each "fix" cleans the cache, I am thinking that it's some sort of caching problem, but what???
