Recently I was suffering from a really slow Mac. Everything will be stuck whenever I clicked on something. This could be really frustrating especially when I am trying to program. I checked my software to see if they needed any updates or anything. However, everything looks fine. I also monitored all the activities that was going on on my Mac, everything seems normal, except my RAM was being used 3.85 GB out of 4 GB. I thought it would be my RAM’s problem, so I upgraded my RAM from 4 GB to 10 GB. However, the problem still exist.
At this point, I know that it shouldn’t be my RAM’s problem, neither could be my software’s problem. Then there is only one possibility. My hard drive is failing, the cause of this problem could be accidentally dropped your Mac on the ground, or moving your computer while the operating was still in process. Some times, this problem could be resolved by re-install OS X system on your Mac. On my Mac, after I re-install my Mac, the problem seems to be solved. If your problem has not been solved I would suggest you to change your hard drive to an SSD.
SSD is short for solid state drive, it is faster and more stable than SATA. SATA access data by putting everything in your temporary memory first, then when you actually save your data on your drive, they would put your files in your hard drive. There might be a data fragment happening if you moved your computer or dropped your computer when your machine is still in process of something. Once your Mac has create the fragment, your hard drive could be failing based on that. An SSD will access data directly from the drive. In that way, there is less chances that your data will be lost. Therefore, I would recommend everyone to replace your SATA drive to a SSD if you ever need to change your drive.
There is a website you can check out how to fix all your Mac problems step by step. It is called iFixit.
