How Can I Create bootable usb install for macbook pro 2012 on a PC?

macOS uses a different file system (HFS+ or APFS), and if you try to create bootable USB install for Macbook Pro without the right format, it may not work. Make sure you format your USB to ExFAT initially through Disk Management in Windows. Not all macOS versions are compatible with the 2012 MacBook Pro. If you try to install a version that’s too advanced, you'll run into errors. Stick with versions like High Sierra (10.13) or Mojave (10.14), as these are known superstars for older hardware and should give you fewer issues than something like Big Sur or Monterey.

Once you've created bootable usb install for Macbook Pro 2012, it’s easy to mess up the boot process on the MacBook itself. If you're not holding down the right key, you might miss the boot menu. Make sure to hold the Option key as soon as you power on the Mac. A lot of folks get impatient and either press it too late or release it too early, which can lead to booting from the internal drive instead.

If after booting from the USB, you find yourself stuck, go to Disk Utility from the macOS Utilities menu and format the internal drive with Mac OS Extended (Journaled) or APFS. This could be vital for a smooth installation.
