Best place to sell a Macbook? 💻

I've found this to be a huge hidden gem. Give it a try and also you can post to local selling pages which increases visibility.

OfferUp, LetGo, Wish local- Take a few pictures and post it everywhere. Wherever you get the best offer is your winner

All of the marketplaces mentioned in the above answers are really awesome. If you don't want to meet up with the buyers off those marketplaces, you can use PayOnDelivery to collect payment and set up delivery service!

Gazelle is the pain free way I use to get rid of old MacBooks, iPhones, etc. Not entirely sure if you always get the best price but worth it for me due to lack of hassle. They ship you a prepaid box and you ship it back.

Its really the most robust market, and because its such an active market theres p much always going to be someone looking to buy which ever model you've stepped out of.
