Pros

• You can macOS sequoia full installer download independently, bypassing App Store download restrictions to obtain the complete, original installer.
• The entire process uses official Apple components; it is unmodified and clean, resulting in a bootable USB drive with exceptional compatibility and stability.

Cons

• The installer package is large, requiring a stable internet connection and sufficient local storage space for download.

Notes

• Make sure your Mac has sufficient battery power or is connected to a power source during the download and installation process to prevent the installer from becoming corrupted due to a power outage.
• When formatting the USB drive, you must select Mac OS Extended and GUID Partition Table; otherwise, it cannot be created as bootable media.
