I have a problem installing Mac OS Sequoia. Goign through the entire process, described below, the mac keeps on booting up from the flash drive to the screen with the 4 option (see image in step 22 below). It never finishes the Mac OS install process.
Here are the steps I took:
- Boot Mac OS holding down Option+Command+R to initiate Internet Recovery
- Disk Utility - Erase SSD and select APFS file format naming the hard drive as Macintosh HD
- Go through process to install Mac OS Sonoma (latest Mac OS supported on this Mac)
- After installation, install all possible software updates.
- Download OpenCore-Patcher.pkg from https://github.com/dortania/OpenCore-Legacy-Patcher/releases/tag/2.4.1
- Launched the Open Core app
- Clicked Create macOS Installer
- Clicked Download macOS Installer
- Selected the latest macOS Sequoia in the list, then click Download
- Inserted a 256GB USB-C SanDisk flash drive into the USB-C port
- Clicked "Yes" when asked Create macOS Installer?
- Clicked the displayed Install macOS Sequoia
- Clicked on the SanDisk displayed
- Then clicked "Yes" on the Are you sure you want to erase 'SanDisk Ultra'? All data will be lost, this cannot be undone.
- After installing the installer on the flash drive, clicked "Yes" on Installer created successfully, would you like to continue and Install OpenCore to this disk?
- Then clicked on Install to disk on Finished building your OpenCore configuration! Would you like to install OpenCore now?
- Selected the SanDisk flash drive from the list
- Clicked on "reboot" in the next window OpenCore has finished installing to disk. You will need to reboot and hold the Option key and select OpenCore/Boot EFI's option. Would you like to reboot?
- While rebooting I held down the Option key on the keyboard
- In the bootup menu I selected the "EFI Boot" option
- In the next menu selected "Install macOS Sequola"
- In the next menu selected "Install macOS Sequela Use the attached installer to Upgrade or Install macOS."

- Selected the Mac's hard drive to install Sequoia on
- After installation and reboot a few times, the screen in step 22 keeps coming up.
Am I doing something wrong? How do I correct this.
