My trackpad stopped working. I installed Yosemite and now it works?
I have a mid 2009 13" macbook pro. The bottom left trackpad was all but non functional. I was about to replace it and thought if I installed Yosemite it might have caught a driver to improve function. It now works perfectly. Is there a driver missing in Lion that Yosemite fixes? I am unable to do D or option D to do a diagnostics as it won't work. I also do not have the original system install disc so I can't figure out a way to do a self diagnostic.
Is this a good question?
Can you give us the last four digits of your serial number so we can correctly identify which model you have.

066E is the serial number. Thanks.
