Oh and also after the restart to fix it this is my ram:

And yes i do regualy clear my chaches i just did this morning before the restart i clear my google chrome, safari and navigate to my cache folders and remove all of those. Even the hidden one.

I have hotspot shield uninstalled at least is should be.... And i use google music manager... i shouldn't have to sacrifice things i use daily just to make my computer go better because apple made a unstable release. Also can you tell my how to uninstall is i was pretty sure i did but i guess not.

if your seeing hotspot shield from boot up items it wasnt actually in there is said unknown so its gone now..
