Is there a way to test for sluggishness?
I have been working on a MacBook Pro, Late 2011, MD314, A1278. It has the Intel i7 2.8GHz processor, 8GB of memory, and a 750 GB HDD. It runs OS X Yosemite. However, I have had reports of sluggishness; slow response upon opening applications, slow to access files, and dealing with settings.
