How do you reset an Apple time capsule to factory settings?

We assume that the Time Capsule is operational and connected to your network.

Open AirPort Utility on your Mac (Finder > Applications > Utilities > AirPort Utility)

Click on the Time Capsule to select it

Click Edit in the smaller window that appears

Click the Disks tab at the top of the next window

Click Erase Disk

Select the Zero Out Data erase option for a secure erase

Click Erase

The operation will take some time.......on average about 6-8 hours

When the Erase has completed, click the Base Station menu at the top of the screen

Click on Restore Default Settings

That's it

Not sure why you want to reset the Time Capsule, but if you plan to sell or give away the product, you would also want to erase the data on the Time Capsule's hard drive.

But, if you reset to factory settings.......you won't be able to erase the hard drive.

How do you want to proceed?
