Q: Macbook Pro slow after updating to mac os sierra

I updated to my Mid 2012 Macbook Pro to OS X 10.12 yesterday and at first it was running fine, but then whilst I was watching videos in VLC I noticed the video would freeze and that my laptop would slow down. I performed a restart and upon restarting it I noticed that signing in was taking longer than usual. Eventually I got in and tried to use it normally, but I noticed that each time I clicked on anything I would get the beachball and that there is just a general lagginess to everything now. I restarted, reset the SMC but the issue persists. Does anyone know how to fix this issue?

I also ran a EtreCheck and the results are below.
