Can you hack a social media account on a Mac?

Hello,

In new to hacking (extremely new) and was wondering if there is any software that will allow me to hack into social media accounts.

For context, I went rogue on the internet between 2013-2016 and made several instagram accounts (and a musical.ly), I want to see what I posted but obviously can’t do that (that’s why I’m wanting to learn how to hack).

I’m not doing this to be malicious, i just want to see what little me was up to back then.

Thank you!
