Busy cursor and Mac OS too slow even moving to SSD
Hi! On the last week my MacBook turned very very very slow .
I've restarted some times, removed apps from start, purge memory During the executing but without success .
So I change the HD to and Kingston 120GB SSD , I reinstalled the Yosemite and the MacBook remains slow .
I ran the AHT (Apple Hardware Test ) and he is fine .
Someone have any idea to help?
MacBook Pro 13 " Unibody Mid 2012

Is this a good question?
