Spyware Malware
I bought a used Macbook Pro from a reseller on eBay. Now that I have received it, is there any way to know if they possibly loaded spyware or can in any other way get access to information/browsing/passwords? I haven't connected it to my home network or internet nor have I signed in with my iTunes yet because I'm a bit paranoid. It has Catalina loaded.
