Hi Guys, This is my first post, so Hello everyone! I bought my first mac a couple a month ago, a refurbished model (late 2013 21.5-inch 2.7 i5 1TB HDD) and since I bought I feel like the HDD is not performing well... It takes a couple of minutes to start and to switch between users, so I installed an app called "Disk Speed Test" from Blackmagicdesign and those are the results: Write: ~60MB/s Read: ~60MB/s So, my question is, are those results the expected for this kind of HDD? is it underperforming? should I go to the apple store? Thank you so much in advance for your help!
