Installation is similar to any other standard laptop. Please keep in mind that the volume of the startup sound can only be modified reliably in OS X. Just boot in OS X, mute your system sound and reboot again to the Arch Linux Installation media. Note: If you plan to remove OS X, it is advisable to disable the MacBook startup sound before proceeding with partitioning.

If you plan on keeping OS X for the purpose of dual booting, you need to manually shrink the main OS X HFS+/APFS partition from within OS X's Disk Utility program.

MacBooks are partitioned using the GPT scheme by default. However, if you plan to remove OS X completely, make backups of these files, which you will need in Linux for adjusting the color profile: It is advisable to keep OS X installed, because MacBook firmware updates can only be installed using OS X. Note: If you uninstalled OS X or want to reinstall it, Apple has great instructions.
