Even after Apple discontinued Time Capsules, the corporate continued to supply Time Machine with macOS. All so customers might each use it to again up and to proceed to assist customers who nonetheless had working Time Capsules.
We coated learn how to purchase and refurbish a fifth technology Apple Time Capsule in a earlier article. We additionally coated learn how to use Time Capsules on a contemporary wi-fi and wired community utilizing Apple’s AirPort Utility app, additionally included with macOS.
You too can nonetheless obtain Time Capsule Consumer Guides for third, 4th, and fifth technology Time Capsules from the Apple Assist website.
