MacOS via USB connection
Need a clear, step-by-step process for installing a full MacOS installation from USB without an installer. You're using a MacBook Air 2013 without an SSD and want a complete working system. Let me know if you'd like tips on preparing the drive, backing up data, or verifying the setup afterward. Thanks!
It looks like you can likely run the installer on a functional Mac and choose the USB in the drive list. The main issue here appears to be that your Mac isn’t working properly. If it isn’t, consider finding an image you can copy onto the USB drive. Alternatively, you could boot into Recovery Mode and use Disk Utility to select the USB, which might display an older installer like 10.13. It’s a good starting point.
