Remote FileVault unlock in macOS Tahoe 26

macOS 26 adds a super handy backend change: you can unlock FileVault over SSH before the system fully boots. That means real lights-out access for studio machines.

What it enables

• Limited SSH runs at pre-boot. Log in with the Mac’s local username and password to unlock FileVault, then the system finishes booting.
• After unlock, normal SSH and Screen Sharing work.

How to set it up

1. Turn on FileVault.
2. System Settings → General → Sharing → turn on "Remote Login" (SSH).
3. Reach the Mac over the same network or your own VPN – this is not a public-internet thing.

Flow

• After a reboot, the Mac waits at the login screen.
• From another Mac: SSH to it → enter the local creds → disk unlocks → full boot → Screen Sharing connects.

Wi-Fi didn't work but plugging into Ethernet made it work reliably.
