Thanks for the response. kSecUseDataProtectionKeychain only available above mac OS 10.15+. I plan to implement in lower version too. What i really need is a separate keychain which is accessible to my app only (unlocked by password provided while creating keychain). Suppose i create a keychain with security command, am i able to use that keychain with Keychain API? I don't want to store in login keychain as it is not accessible for all user. I need a keychain which can be accessed throughout all users, like System keychian. Can I create a keychain in /Library/Keychains ? Help if this is possible.

I need a keychain which can be accessed throughout all users What i meant is, items added in my keychain should be accessible from any user. If i add items in login keychain this is not possible, right? I finally decided to go with security command line tool . Thanks for the response.

Yes. I'm a member of Apple Developer Program

Recently I got a message from my organization saying "All apple accounts needs to be managed by them". As part of that I transferred my account and was needed to change the country. Can this cause any issues in notarization?

@ryanollos Did you create Individual API Key or Team Key?

As per mentioned thread, is it possible to trust certificates and identities that comes along with p12 certificates through MDM?
