Running a full node on 2015 macbook pro?

Hi friends. I want to run my own node (full node ideally), but do not want to buy a raspberry pi or spend money to do it. I have an old 2015 macbook pro that is my main personal computer, however i dont use it a ton now that i am no longer in school. Will running a full node on my macbook greatly effect its performance? Of course i will store the blockchain on an external hard drive. Has anyone tried this with a similar computer and had success? Also, if a full node is not possible would it run a pruned node with no issues?

Thanks for your help!
