Before Installing macOS 27 Public Beta

1. Back Up Your Mac

Before installing any beta software, create a full backup using Time Machine or another backup solution.

If something goes wrong, you'll be able to restore your Mac without losing your data.

2. Free Up Storage

Here are a few quick ways to free up space:

• Empty the Trash
• Delete large files you no longer need
• Remove old downloads
• Uninstall apps you rarely use
