Apple has released a new supplemental update for macOS High Sierra 10.3. The macOS High Sierra 10.3 update is designed to fix a couple of issues with High Sierra.
We previously heard about a Keychain vulnerability in High Sierra, this has now been patched in the update.
Keychain Vulnerability Fix
The Keychain vulnerability was a significant security concern for many users. This flaw allowed unauthorized access to the Keychain, which stores passwords and other sensitive information. The vulnerability could potentially expose user data to malicious software or unauthorized users. Apple has addressed this issue in the latest supplemental update, ensuring that the Keychain is now secure and that user data is protected. This fix is crucial for maintaining the integrity and security of macOS High Sierra.
APFS Volume Password Issue
The macOS High Sierra 10.3 supplemental update also apparently fixes an issue where High Sierra shows you a password instead of a password hint on an encrypted APFS volume. This issue was particularly problematic for users who rely on encrypted volumes to protect their data. Displaying the actual password instead of a hint could lead to unauthorized access if someone else viewed the screen. Apple has provided full instructions on how to fix this issue over at Apple.
In addition to these critical fixes, the update includes several other improvements and optimizations to enhance the overall performance and stability of macOS High Sierra. Users have reported smoother operation and fewer crashes after installing the update, making it a recommended download for all High Sierra users.
The latest version of macOS High Sierra is now available to download with these fixes included. You can update to the latest version via Software Update in the Mac App Store. To do this, simply open the App Store on your Mac, click on the “Updates” tab, and look for the macOS High Sierra 10.3 supplemental update. Click “Update” to download and install the update. It is always a good idea to back up your data before performing any system updates to prevent data loss in case of any issues during the update process.
Apple continues to work on improving macOS High Sierra, and users can expect more updates in the future to address any new issues that may arise. Staying up-to-date with the latest software updates is essential for maintaining the security and performance of your Mac.
