I’m trying to clean install macOS Big Sur with network boot (Catalina won’t boot due to some error), but after a few minutes of waiting, error 2002f appears on the screen. How to fix it?

We’ve already covered all the ways to update your operating system to macOS Big Sur on any compatible Mac. If you are forced to stop at online system restore, you may encounter errors while downloading data from Apple servers.

This error is not the first year occurs among users around the world. The thing is that during recovery, the computer downloads data from Apple servers and remotely checks for binding to a specific Apple ID account. The error occurs only in the second case, but the download will not continue without this.

How to fix error 2002f in Apple

On thematic forums and when contacting the support service, such a problem is recommended to be solved as follows:

1. Restart the computer and the router through which the connection to the network is made.

2. Change the router’s DNS settings from to Google’s public DNS : .

3. Connect your Mac to the router using an ethernet cable.

4. Try to boot the system by connecting to another network.

Such actions do not help everyone and the error continues to interfere with the installation of the system.

How else can you fix error 2002f

Users on the net have found a simpler and more affordable solution that helps to avoid this error. To prevent the computer from being checked for linking to an Apple ID account during online recovery, you must first disconnect it from your account.

1. From any device, go to the Apple ID account management page and log in.

2. In the Devices section , find the Mac on which you will reinstall the system via the Internet.

3. Unlink this Mac from your account.

After that, the corresponding check will not occur during the installation, and the 2002f error will not occur.
