Hello, We have an application which gets our HSM certificates via TKTokenWatcher, there is a snippet: let tokens = TKTokenWatcher() for token in tokens.tokenIDs { // Use our HSM certs if token.contains("SPECIFIC_IDENTIFIER") { let tokenQuery = [kSecClass as String: kSecClassIdentity, kSecAttrTokenID as String: token, kSecAttrKeyType as String: kSecAttrKeyTypeRSA, kSecReturnRef as String: true] as CFDictionary var item: CFTypeRef? let result = SecItemCopyMatching(tokenQuery as CFDictionary, &item) if result == noErr.... Normally, result is all right, but problem occurred when we added "App Groups" entitlement. This application has to share some Defaults with other app, so they need to be in the same App Group. So, when we added this App Group entitlement, result from the code snippet is -34018, which according to OSStatus means errSecMissingEntitlement. Does anybody know, which entitlement has to be added, so app can be in the App Group, and at the same time it is able to get certificates? Thank you.

Hello, It is mentioned in CryptoTokenKit documentation: You use the CryptoTokenKit framework to easily access cryptographic tokens. Tokens are physical devices built in to the system, located on attached hardware (like a smart card), or accessible through a network connection. However, it looks like there is lack of documentation with simple example, how to access network token. I have a certificates in HSM (hardware secure module), which is accessible on network, and I'd like to access certificates on HSM on my Mac. Does anybody know, where to start with implementation? Thank you.

Hello, I have an app, which runs fine on Monterey, but crashes on Big Sur. However, I am able to run it on Big Sur from XCode only.

I would appreciate any idea what can be wrong here, and why there is no problem on Monterey (both M1 and Intel), but crashes on Big Sur?

Hello, I would like to ask, is there any option how to emulate Big Sur (eventually older versions) on MacBook with M1 and Monterey OS? Thank you.
