Slow start up & shut down after updating to OS 10.10.5
I bought an Apple Macbook Pro (non-retina) three days ago with standard configuration. I updated the OS to 10.10.5 today. Now I am encountering a few problems -
1. Slow start up! Takes almost 5 times more than before to log in.
2. Significantly slower operation.
3. While shutting down, screen goes black immediately with only cursor remaining on screen. It finally shuts down after a 4/5 mins. Previous shut down time was 5-10 sec.
Any solution of the above???
MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.5)
