How to Upgrade your Mac to macOS Sonoma

This guide is about upgrading your Mac to macOS Sonoma the latest version of the Mac Operating System from Apple.

Before you proceed with an upgrade, we suggest you to check the compatibility of the Mac model.

NOTES:
  • If you're running macOS Sierra or later and planning to upgrade to macOS Big Sur, you'll require 40 GB of storage for an upgrade. If you're running a previous release than macOS Sierra, you'll need upto 50 GB of storage for an upgrade to macOS Sonoma.
  • If you're running OS X Mountain Lion, you'll need to upgrade your Mac to OS X El Capitan first and then to macOS Ventura.
  • Currently, macOS Sonoma is under Beta and it's not recommended for daily driver use.

STEP 1: Create a Backup of your Mac
Before you proceed with an upgrade, we advise you to perform a backup of your Mac. In case the upgrade fails or you encounter any issue with the upgrade, you can roll back to your existing installation.

To create a Backup for your Mac, follow the guide below

STEP 2: Download macOS Sonoma
The second step is to download macOS Sonoma. A copy of macOS is currently available to developers who have enrolled in the Apple Developer Program. If you have still not enrolled in the program, there's still a way to it which has been referenced below.

To download macOS Sonoma, follow the steps below

1. If you're using macOS Mojave or later, you can obtain macOS Monterey via your developer account. Sign in to your Apple Developer Account
2. From the left pane, click on Downloads
3. Scroll down and under Overview, select macOS.
4. Under macOS Beta Software, use the link to download macOS Developer Beta Access Utility.

If you plan to perform a clean installation, follow the guide below

STEP 3: Installation
Once the download completes, the installer will open automatically. Click on Continue and follow the instructions. At last, select your target drive and click on Install

NOTES:
  • If the installer asks for permission, enter your password when prompted.
  • During the upgrade process, your Mac might restart several times. You might get a blank screen at certain times but that's normal and the installer is still working in the background.


1. From the Applications folder, right-click on Install macOS Sonoma beta and click on open
2. Click on Continue and then continue with the options as shown below.

You'll need to use an SSD, upgrade the IGPU or install a compatible GPU, create a new EFI from scratch and then you should be able to install it.
 
Hello guy, I found a solution to this in my recent posts on this day 4th July 2024
