Click on Time Machine and you can set it up. Connect the drive to your iMac and then go to the Apple menu and open System Preferences. You need an external hard drive to use Time Machine. Time Machine can help you recover that file. Though it rarely happens, if you use your computer enough, there will come a time when you a file you’re working on goes bad, or you lose it, or you want to revert to a previously saved version. It’s called Time Machine, and it’s really easy to set up and use. The Mac operating system (called macOS) has a built-in feature for making backups of your data. That hard drive would be handy for the next step listed below. We also reviewed the WD_Black D50, a dock with a built-in 1TB hard drive for $449. We recently reviewed the OWC Thunderbolt Hub ($149) and liked it. There are a variety of docks available with different port offerings. This is a box that provides a set of different connectors you can plug into. If you have a lot of devices you want to connect, consider investing in a Thunderbolt dock. We have a complete guide to help you find the adapter you need. If you have a device that uses a different version of Thunderbolt, you need an adapter like Apple’s $49 Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter ( Amazon link). Apple has one for $19 ( Amazon link), but you can find third-party versions for a little cheaper. So the adapter you will need is a USB-C to USB adapter.

You’ll probably need Apple’s USB-C to USB adapter (left) and Thunderbolt (USB-C) to Thunderbolt 2 Adapter (right).Ĭhances are, the device you want to connect uses a USB-A connector, the most widely used version of USB.
