Creating the USB

To install macOS we need to create a bootable USB first. We can do this either on macOS itself or any windows PC. We can create both online or offline USB.

Online vs Offline Installer

Offline installers have a complete copy of macOS, while online installers are only a recovery image (~500MB) which then download macOS from Apple servers once booted.

• Offline
  • Can only be made in macOS
  • Windows/Linux do not have the APFS/HFS drivers needed to assemble a full installer
• Online
  • Can be made in macOS/Linux/Windows
  • Requires a working internet connection via a macOS supported network adapter on the target machine

Making the Installer

Depending on which OS you're on, see your specific section on making the USB:

• macOS users
  • Supports OS X 10.4 to current
  • Supports both legacy and UEFI installs
• Windows users
  • Supports OS X 10.7 to current
  • Online installer only
  • Supports both legacy and UEFI installs
