Noob question here.

If I'm a beginner, what's the best way to hack into a victim who is on a same wireless network as me and is using a MacBook? I'm talking about things like installing a RAT tool.

There are some hacking techniques like DNS spoofing and Man in the Middle where you can get information like usernames and passwords. For example, if your victim is using a username and password to log into a web page, you can get that password easily. On the other hand, if you want to transfer and run a RAT on his/her computer, you can use a similar technique; however, in this case, you have to clone a web page (you have to use your own HTTP server and your victim will connect to your web-page instead of the original web) and exploit a vulnerability on your victim browser to be able to transfer and run a RAT on his/her computer.

Shortly, you have to find informacion about those topics: DNS spoofing, Man in the Middle, browser vulnerabilities, buffer overflows, and shellcodes.

This,
And you can also force redirect him to a fake webpage and make him download and execute your RAT server.
