2. “Forbidden – An error occurred while installing the selected updates.”

The reason behind the forbidden-An error that occurred while installing the selected updates is hard to detect. However, it doesn’t mean there is no solution for that; we’ve also dealt with such errors and, of course, fixed earlier significant updates as well as macOS Sonoma.

The first fundamental trick is rebooting the system and downloading the macOS Sonoma update again. Secondly, if you still have a beta profile installed, remove it from the system and download the update. And if none of the tricks works for you, then consider it as an Apple Server error. In such cases, you cannot do anything but wait for few hours and try again.

Furthermore, the Mac running macOS Sonoma and/or T2 security chip, then make sure all the security updates and BridgeOS updates are installed and up to the mark before downloading the macOS Sonoma. So Turn on Full Security Mode in Recovery mode. Follow the below steps,

  1. On Apple Silicon Mac:- Shut down your Mac, wait for 10 seconds, and Press and Hold on the Power button until you see startup volume with Option.
    On Intel Mac:-Turn on your Mac, And Quickly Press and Hold on “Command+R” Key from the Keyboard after apple logo appears on the screen.
  2. Next, your Mac startup in recovery screen and Enter your Mac login password if asked.

  1. That’s it. Restart your Mac and check are you able to download macOS On Mac software Update.

3. “Installation failed” – an error occurred while installing the selected updates.

Well, Installation failure is most likely due to Apple Server outages, so we cannot do anything until Apple fixes their problem. You can keep checking the Apple Server Status Page, where Apple’s all services are listed with their real-time running status. If the macOS Software Update is green, then it is active and working.

4. “The package %@ is missing or invalid” Error Message

The package missing or invalid error message appears when the update package is incompletely downloaded or download paused/stopped for some or other reason. Alternatively, pending software/security updates could cause this error; therefore, make sure all the pending updates are installed in your device and then try to install macOS Sonoma. Here’s one more catch, do you have an alternate internet connection? If yes, then connect Mac to other Wi-Fi and try your luck.

Still are you getting Error on macOS Sonoma installation,

Restarting Download or Turn on pushed download, will be continue from when you left.

Download Failed is the most common error message that appears while installing major updates on Mac. Here what you can do is, don’t use VPN while downloading software updates, close all the background applications, and then install MacOS Sonoma. Our objective is to keep the Mac as light as possible by closing the programs and apps that you don’t need while updating the Mac.

7. MacOS Sonoma downloads extremely slow

When MacOS Sonoma slowly downloads, choose a time when people don’t update their Mac, like you can try downloading the update overnight or wait for a few hours and retry. This is the only solution when Mac downloads updates slowly.
