- Click Keychain Access in the menubar.
- Hover over Certificate Assistant and click Request a Certificate From a Certificate Authority.
- Fill out the request form with your own information.
- For CA Email Address, you should check services like VeriSign, Inc. or RSA Data Security Inc. These are companies that verify the identities of computers on a network and issues certificates.
- Choose whether or not you want the certificate emailed to the CA or Saved to Disk.
- Click Continue.
- If you chose Saved to Disk, specify the location to save to.
- Locate the certificates and open them with Certificate Assistant.
- Select the Issuing CA from the drop-down menu.
- You can choose to override the defaults if need be.
- Click Continue.
- Select the Create a certificate for yourself option.
- Click Continue.
- Double check the information, and then click Create.
- You should select Self Signed Root as the default.
- Certificate type should be S/MIME (Email).
- It will prompt you for confirmation. Click Continue.
- Your certificate has been created, so click Done.
Once you create your certificate, it is automatically added to Keychain.
How do I send digitally signed and encrypted emails on Mail for Mac
When you have your certificate, it means that your recipients can verify you as the sender, adding another layer of security. However, to send encrypted messages, the recipient's certificate must be in your keychain.
- Launch Mail on your Mac.
- Click on the Compose button, or File > New Message to create a new message.
- In the From field, click and choose the email account that you have a personal certificate for in your keychain.
- In the subject line, there will be a checkmark box at the end on the account with a certificate. Click the checkmark button to turn on your digital signature.
- Address the email message to your recipients.
- The Encrypted symbol (closed lock) will appear next to the Signed icon if you have a certificate for every single recipient that the message is being addressed to.
- If you do not have the certificate for all recipients, then the message must be sent unencrypted.
How to receive digitally signed and encrypted emails on Mail for Mac
Again, remember that you need to provide senders with your own verified certificate in order to receive encrypted messages.
Mail for Mac has a Security field in the header area that indicates whether a message is signed or encrypted.
Best Encrypted Email Providers
- For signed messages, you will see a signed icon (checkmark) in the header. If you need to, just click the icon to view certificate details.
- Messages that are altered after they've been signed will have issues with verification.
- For encrypted messages, a lock icon appears in the header. If you have your private key in Keychain, the message will be decrypted for viewing. Otherwise, it won't be decrypted.

Apple has announced that its newest retail store, Apple Sanlitun in Bejing, is opening to customers in the area later today.
Mac computers that have the Apple T2 Security Chip integrate security into both software and hardware to provide encrypted-storage capabilities. Data on the built-in, solid-state drive (SSD) is encrypted using a hardware-accelerated AES engine built into the T2 chip. This encryption is performed with 256-bit keys tied to a unique identifier within the T2 chip.
The advanced encryption technology integrated into the T2 chip provides line-speed encryption, but it also means that if the portion of the T2 chip containing your encryption keys becomes damaged, you might need to restore the content of your drive from a backup. This content includes system files, apps, accounts, preferences, music, photos, movies, and documents.
Always back up your content to a secure external drive or other secure backup location so that you can restore it, if necessary. You should also turn on FileVault for additional security, because without FileVault enabled, your encrypted SSDs automatically mount and decrypt when connected to your Mac.
Make a backup
Set up Time Machine or another backup method to regularly back up your Mac to a secure external source.
Files that you store in iCloud Drive, as well as photos and videos that you store in iCloud Photo Library, are automatically uploaded to iCloud. When you use iCloud Photo Library, full-resolution photos and videos are stored on your Mac by default and included in a Time Machine backup. If you choose to optimize iCloud Photo Library on your Mac, the full-resolution originals are not included in a Time Machine backup.
Turn on FileVault
Though the SSD in computers that have the Apple T2 Security Chip is encrypted, you should turn on FileVault so that your Mac requires a password to decrypt your data.
To turn on FileVault, follow these steps:
- Choose Apple menu () > System Preferences, then click Security & Privacy.
- Click the FileVault tab.
- Click , then enter an administrator name and password.
- Click Turn On FileVault.
