Activity is logged to a file based on your OS:

• Linux/macOS: /tmp/os_flip_<username>.log
• Windows: %TEMP%\os_flip_<username>.log

Useful for debugging or audit trails.

📌 Notes

• Linux: Edits /etc/default/grub, then runs update-grub or grub2-mkconfig
• macOS: Uses bless to set the startup disk (requires SIP-safe paths)
• Windows: Uses bcdedit to read/set boot configuration
• The script auto-launches in a new terminal if not already interactive
• GRUB backup is created before changes (/etc/default/grub.bak.<timestamp>)
