Sorry if this is the wrong forum for this, feel free to move if it is. I've recently started having issues with my Macbook Pro. It's a little over 4 years old now and this is really the first time I've had an ongoing issue with it. A few days ago it started freezing and I've had to manually shut it down. Just in the last day I've had to do that twice, and it's frozen a total of 4 times. The two other times I didn't have to shut down I just waited for a bit and then it unfroze. Also, today when I tried to do a backup I kept getting the spinning beach ball when I tried to plug in my backup drive. Eventually it did work, and it did let me back up my harddrive. Once the backup finished I ejected the drive then plugged it back in, again I got the beach ball. I tried a different drive, that one didn't freeze but it did take about a minute for it to show up on my computer. Does anyone know what could be happening or what might be the cause of this? Any help is appreciated.
