After the MacOS version is updated to 12.6.1, the personal VPN cannot be connected. After troubleshooting, the sharedSecretReference may be invalid.(The sharedSecretReference is obtained from the keychain)
os update before: security default-kechain-> "/Users/admin/Library/Keychains/login.keychain-db"
os update after: security default-kechain-> security: SecKeychainCopyDefault: A default keychain could not be found.
Although it can be corrected by this command :security default-keychain -s "/Library/Keychains/System.keychain"
then,VPN can connect.
I wonder if it is possible to fix this problem through code? Or is the code OK? This is a bug in the Apple system?
