Mac Restart Key

You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.

Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.

Hold the keys down until the computer restarts and you hear the startup sound for the second time. Keyboard Shortcuts to Shutdown/Restart a Mac. As a safety, these shortcuts require you to hold them down longer than you would a simple shortcut command, e.g., ⌘ + Z to undo changes. To shut down your computer without any prompts to save or closing out applications, press and hold the Power button. Save and Quit Before Restart/Shutdown.

About Terminal

Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.

To open the macOS Terminal, follow these steps:

  1. In Finder, choose Utilities from the Applications folder.
  2. Find Terminal in the Utilities listw.
  3. Open Terminal.

The Terminal window opens with the commandline prompt displaying the name of your machine and your username.


Generating an SSH key

An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.

To generate SSH keys in macOS, follow these steps:

  1. Enter the following command in the Terminal window.

    This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.

  2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

  3. Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.

You will need to enter the passphrase a second time to continue.

After you confirm the passphrase, the system generates the key pair.

Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same Triton Compute Service account.

Never share your private key with anyone!

Your public key is saved to the;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:

Importing your SSH key

Now you must import the copied SSH key to the portal.

  1. After you copy the SSH key to the clipboard, return to your account page.
  2. Choose to Import Public Key and paste your SSH key into the Public Key field.
  3. In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
  4. Add the key. It will now appear in your table of keys under SSH.


You may see a password prompt like this:

This is because:

  • You did not enter the correct passphrase.
  • The private key on your Macintosh (id_rsa) does not match the public key stored with your Triton Compute Service account.
  • The public key was not entered correctly in your Triton account.

In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.

The FileVault option in macOS is a fantastic way to enhance the security of your data at rest. It’s full-disk encryption (FDE), meaning that your entire startup volume is locked away when macOS is shut down (not just sleeping) using strong encryption. Without the password that unlocks an account on your Mac that’s authorized to log in with FileVault, there’s no effective way to bring that computer to life.

That’s a problem, however, if you forget the password to all the authorized account or, in some cases I’ve received a few emails about, something goes wrong and the Recovery Disk—used both for “cold start” logins to macOS and to diagnose problems on your startup volume—demands a login that doesn’t work.

In those cases, the recovery key set at the time you turned on FileVault on your Mac can do the trick. But if enough time has passed, you might have forgotten where you stashed the key or how to retrieve it. Macworld reader Elaina falls into that camp. She can’t find the key, and she remembers using the iCloud option to store it, but has examined iCloud Drive and can’t find it. She hasn’t yet been in a situation where she needs it, but she’s concerned that you could wind up locked out and not be able to obtain the recovery key.

This is a problem with security options on systems reliable enough that you don’t have to work with them regularly to refresh your memory. (And it’s why Apple shifted iOS two years ago to require that you enter your passphrase every six days, even if you have Touch ID enabled.)

When you first set up FileVault in the Security & Privacy system preference pane in the FileVault tab, one of the steps asks you whether you want to use your iCloud account as a way to unlock your disk and reset your macOS account password if you can’t find your recovery key.

If you choose iCloud, the recovery key isn’t stored loosely in iCloud Drive or as a file, but it’s tied into behind-the-scenes account information that Apple maintains. It’s fully encrypted in such a way that even Apple doesn’t have access to the unencrypted recovery key data, but Apple can deliver the encrypted recovery key to your Mac if you need to reset your password. You never see the recovery key nor have to enter it in this configuration. (The process is a little involved: Apple describes it in the section “Reset using the Reset Password assistant (FileVault must be on)” in this support document.)

If you choose the other path, where FileVault generates a recovery key and displays it, you need to make sure and write it down or enter it electronically, and store it securely in such a way that you’ll have access even when your Mac can’t be booted. I use 1Password’s secure notes for this purpose, but any method of storage that’s reliable, secure, and accessible will work.

Mac Restart Key Commands

A good strategy would be to set a quarterly reminder to look for your recovery key (and other important passwords and keys you have to store in the same place). If you can’t find it, disable FileVault in macOS and re-enable it. This will take a while, as the entire drive is decrypted and then re-encrypted, but macOS generates an entirely new recovery key, which you can then more carefully note again.

With each of the above situations, if you can’t log into iCloud or you lose the recovery key, your Mac’s files are irretrievable forever, as I wrote about last year.
