Apple 12" Intel Core M5 512G SSD Macbooks

Per the specs:
Mac OS 10.11 El Capitan

No apple warranty. You’d need to ask Apple about a service plan.

Mine came with Sierra, and I suspect they all do. High Sierra is a free upgrade.

(Edit: Specs and ThunderThighs, The Voice of Woot say El Capitan. High Sierra is a free upgrade that this machine runs quite happily at any rate.)

1/4 the drive space, bigger and heavier, and 2-3 hours less battery life. If that fits your needs better, there’s certainly nothing wrong with the MBP. But if you’re looking for something as minimalist as a real laptop gets, the model of MacBook offered here is $1,209 refurb direct from Apple.
