If you lose your MacBook or it gets stolen, use Find My network for better chances of recovery. Stolen desktop Macs are harder to find without power.
Encrypt your data with a password on Apple silicon Macs or Intel-based Macs with T2 Security chip. Use FileVault for encryption on Macs without T2 chip.
To locate your Mac, make a FaceTime call if online or utilize Find My app to see location, play sound, lock remotely, or enter Lost Mode.
If Find My is off, change important passwords and end active sessions to secure data. Inform police and insurance company about the loss.
For a lost but untraceable Mac, consider remote wipe as a last resort. Erase the device via Find My and remove it from iCloud account.
Periodically check Find My settings, location permissions, and wake for network access on your Mac for better preparedness.
Consider insurance options like credit card, renters, house, or airline insurance for coverage in case of theft. Backup data regularly and keep an old Mac as a backup.
