Possible Reasons for the Installer Information on the Recovery Server is Damaged

Besides, if you are experiencing MacBook Pro Screen Flickering, don’t worry; here, we will explain how to fix this error and get your MacBook Pro working again.

1. Your Mac Certificate is Outdated

The Mac operating system gives each of its users a one-of-a-kind certificate. This specific certificate can be used as part of the digital identity. This specific certificate has a time limit.

Moreover, for a user to make the most of apple’s capabilities, they will need to renew it. And there is a deadline to do that. When the certificate isn’t valid any longer, Apple is unable to validate your digital identity.

This prevents you from accessing some features, such as reinstalling macOS. In many cases, this is the reason the installer information on the recovery server is damaged.
