I got a message saying “An error occurred installing macOS. The request is timed out.” when updating my MacBook Air 2020 from Catalina to Sequoia. I was able to download the install after a few tries but couldn’t go through the updating process due to the error. Please help!

You can install macOS Sequoia from Terminal if directly running the installer always results in the error “An error occurred installing macOS. The request is timed out.”

Here’s how:

  1. Open Terminal.
  2. Run the command below to see all the macOS versions compatible with your Mac.
softwareupdate --list-full-installers
  1. Run the command below to install the latest macOS version, which is macOS Sequoia for now.
softwareupdate --fetch-full-installer --launch-installer
