MacBook operating systems
We recommend you keep your device up-to-date with the latest Apple operating system, called macOS. That said, only certain devices can run the most recent macOS.
Check out Apple’s guide on its macOS releases and which devices are compatible
Update your macOS version
We require our sellers to make sure every Mac is updated before shipping, but it's still good to check for updates once yours arrives.
Step 1. Select the Apple symbol in the bar at the top of your screen.
Step 2. Select “System Settings”.
Step 3. Select “General”.
Step 4. Check to see if any potential updates are needed. If so, you can update your operating system.
Heads up — the update will be followed by a restart, so make sure all your documents are saved.
Windows operating systems
For Windows computers and laptops, it's usually much simpler. For almost all devices, Windows 10 will come pre-installed. While Windows 10 Pro is not common, we're always happy to check if the device you're interested in has it.
Just reach out to us via this form, and make sure to include a link to the item’s product details page. We'll get back to you within 1 business day.
Checking your Windows OS version
Windows makes it easy to check your device for updates. Use Windows Update Manager to check for updates
What about Windows 11?
It's a bit more complicated to determine a device's compatibility with Windows 11 because Microsoft doesn't exclusively manufacture all Windows computers like Apple.
