How to verify the authenticity of manually downloaded Apple software updates If you manually download an update package for Mac, you can verify the signature to confirm that the package is authentic and complete.
Some software updates are automatically verified When you download and install an update from Apple , Apple's digital signature is automatically verified before installation. Double-click the software update package.
Click the lock icon or certificate icon in the upper-right corner of the installer window to see information about the certificate. If neither icon is present, the package is unsigned, and you shouldn't install it.
If you see a different certificate authority, or the certificate doesn't have a green checkmark indicating that the certificate is valid, don't install the package. Click the triangle next to the word "Details" to see more information about the certificate. Let us know in the comments.
