Compatibility Testing

Giving you peace of mind to upgrade your OS, knowing that your current devices will still be fully compatible.

We test everything. Then test it again.

One of the many reasons we love Apple is their constant drive to innovate. At MacSales.com we share that drive, and we constantly improve our own products to deliver the best performance and 100% compatibility. With each new OS revision, you need peace of mind that your current workflow won't be compromised.

That's why we test our products with current and new machines and each OS revision. In our dedicated compatibility lab, our expert techs physically test hardware and software for compatibility with each new Apple OS. We push out patches and drivers wherever necessary, both in-house and third-party, as soon as they become available.

When you see the MacSales.com Compatibility seal, you can rest assured that the product has been rigorously tested and is verified to work with the current OS. Just another way we go further at MacSales.com, to deliver you perfect performance and 100% compatibility.
