Viewing website certificates in the Safari browser on Mac can be achieved in three ways: 1. Use Keychain Access to view the full certificate information, open Keychain Access→Certificate→Find the target website certificate and double-click to view details; 2. By enabling Safari Developer Tools, select "Show JavaScript Console" in the development menu and switch to the network tab page, expand the main requested connection information to view the certificate summary; 3. Use the security options of the Finder Bookmark to view the certificate status, suitable for advanced users and specific automation scenarios. Make sure you have visited the target website so that the certificate appears in the list before each viewing.
When you access a website using the Safari browser on your Mac, viewing the website certificate can help you confirm that the website is safe and trustworthy. Especially before making online payments or logging into an important account, checking the certificate is a good habit.

How to view website certificates in Safari?
Safari itself does not directly provide the "Click Details → View Certificate" button like Chrome, but you can view the full certificate information through the developer tools or keychain.
1. Use Keychain Access to View Certificate
This is the most direct way to view the content of an SSL certificate for a website in detail:

- Open Keychain Access
- Select Keychain Access → Certificate in the menu bar and find the certificate of the website you have visited recently
- Double-click the certificate and a detailed information window will pop up, including issuer, validity period, public key, etc.
If you are not sure which site you are looking for, you can visit the site first in Safari and then go back to the "SSL Account" category in the keychain.
2. View the certificate summary through Safari Developer Tools
If you just want to take a quick look at the basic information of the certificate used on the current page:

- Make sure Safari's development menu is enabled (Preferences → Advanced → Show development menu)
- Visit any HTTPS website, click Development in the top menu bar → Show JavaScript console
- Switch to the Network tab on the console interface, select the main request (usually the domain name line), and the connection information will appear on the right side.
- Click the " ” to expand more details to see the certificate summary and encryption protocol version
This method is suitable for daily quick checks, but there is no complete certificate chain to see.
3. Use Finder shortcut to view certificates (suitable for advanced users)
Another less well-known method is to quickly obtain certificates through Finder:
- Create a new bookmark in the Finder and drag the HTTPS address you want to access in
- Right-click the bookmark → Show introduction → Security section
- If the website uses a valid certificate, the certificate status and related information will be displayed here.
Although this method is not mainstream, it is quite practical in some automation scenarios.
Basically these are the methods. Although Safari does not have a special "certificate viewer", it can be easily done with keychain and developer tools. The key is to remember to make sure you have visited the target website before each viewing, otherwise the certificate may not appear in the list.
