Quick Fix: Implement the ‘applicationSupportsSecureRestorableState’ method in the app delegate and return ‘true’ if your app supports secure restorable state. Verify that you use ‘NSSecureCoding’ for all save and restore operations.
The Problem:
You are facing an issue while launching JMeter or using IntelliJ with OpenJDK versions 11, 17, or 21 on Sonoma 14.0, and receiving a warning about secure coding for restorable state. You need assistance in resolving this issue.
To address the warning “`WARNING: Secure coding is automatically enabled for restorable state! However, not on all supported macOS versions of this application. Opt-in to secure coding explicitly by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState:.”` related to secure restorable state, developers can take the following steps:
2. Determine Customization of State Saving/Restoration:
– Check if your application customizes how it saves/restores its state via methods like `NSApplicationDelegate’s application(_, willEncodeRestorableState:)` and related methods.
– If your app does not customize the state handling process, proceed to step 3. If it does, proceed to step 4.
3. Implementing the Method:
– In cases where no customization is done, implement the `NSApplicationDelegate.applicationSupportsSecureRestorableState:` method in your application delegate class.
– Within the method, return `true` to explicitly opt-in to secure coding for the state saving/restoration process.
4. Verify Secure Coding Usage:
– For applications doing custom state handling, verify that all state-related operations use `NSSecureCoding`. This ensures compatibility with secure coding.
– Once verified, you can implement the `NSApplicationDelegate.applicationSupportsSecureRestorableState:` method and return `true`. This informs AppKit that your app’s custom state handling is compatible with secure coding.
5. Conclusion:
– By implementing the `NSApplicationDelegate.applicationSupportsSecureRestorableState:` method and returning `true`, developers can explicitly opt-in to secure coding for the state saving/restoration process, addressing the warning and improving the security of their macOS applications.
