If you continue to experience this issue, you can try reinstalling it again. However, if it keeps recurring, it's likely due to your Mac/hard drive. Typically, this shouldn't cause any problems.

@@macintoshteam6657 Hello, thanks for responding. How can I reinstall it ? Can I install sonoma directly from USB ? I am unable to login to my system so can’t create a bootable disk from opencore patcher. My mac has opencore patcher installed already. FYI my mac doesn’t support Sonoma directly. Also I ran the Aid from disk utility no error on internal hard drive.

That's fantastic to hear you've already prepared a Solo installation USB. Since you're currently unable to access your system, booting from the USB will be your starting point for the reinstallation process. Here's a step-by-step guide: 1. Begin by inserting your Solo installation USB into your Mac. Think of it as providing the necessary tools for your Mac to perform a fresh start, akin to handing a carpenter the right tool for the job. 2. Now, let's power up your Mac. As soon as you press the power button, press and hold down the Option key. This action serves as a gentle nudge to your Mac, prompting it to consider alternative startup options. 3. Voilà! Your Mac will respond by presenting you with the Startup Manager, a bit like opening a treasure chest of possibilities. From here, you'll spot your Solo installation USB listed as an option. 4. With a click, or more aptly, a tap of the keyboard arrow keys, select the USB drive as your boot source. Think of it as directing a ship towards a new destination. 5. Once your Mac sails smoothly into the Solo installation environment, you'll be greeted with clear on-screen instructions, guiding you through the reinstallation process. Picture it as following a recipe, with each step outlined for a seamless cooking experience. Should you encounter any waves along the way or find yourself navigating uncharted territory, don't hesitate to signal for help! We're here to ensure your journey back to a fully operational Mac is as smooth as a Sunday drive.

@@macintoshteam6657 thanks again. Can I create a installer using open core from other machine ? To install the sonoma ? I can’t access the same machine as I am locked out of the system. I am installing opencore on other machine and create installer and then insert that USB other machine and follow mentioned steps.

@@brian36313 Absolutely! You can indeed create an OpenCore installer on another machine and use it to install Sonoma on your locked-out Mac. Here's how you can go about it: 1. **Prepare the USB Installer**: On another Mac where you have access, follow the steps to create an OpenCore installer on a USB drive. This involves downloading the necessary files, configuring OpenCore properly for your target Mac, and creating a bootable USB drive. 2. **Transfer USB Drive**: Once you've successfully created the OpenCore installer on the USB drive, you can then transfer it to the locked-out Mac. Think of it as passing the baton in a relay race - you're entrusting the USB drive with the task of unlocking your Mac's potential. 3. **Boot from USB**: Insert the USB drive into your locked-out Mac and power it on. Like before, hold down the Option key to access the Startup Manager. From there, select the USB drive as the boot source. 4. **Installation Process**: Your Mac will now boot from the OpenCore installer on the USB drive. Follow the on-screen instructions to initiate the installation of Sonoma. It's akin to sending your Mac on a self-guided tour of its own makeover - with your guidance, of course! By following these steps, you'll be well on your way to reinstalling Sonoma on your Mac and regaining access to your system.
