Every time macOS goes to sleep the processes get suspended which is expected. But during the sleep period, all processes keep coming back and they all get a small execution window where they make some n/w requests. Regardless of what power settings i have. It also does not matter whether my app is a daemon or not Is there any way that i can disable this so that when system is in sleep, it stays in suspended, no intermittent execution window? I have tried disabling Wake for network access setting but processes still keep getting intermittent execution window. Is there any way that i can prevent my app from coming back while in sleep. I don't want my app to get execution window, perform some executions and then get suspended not knowing when it will get execution window again?

I have been trying to find a way to be able to sign some data with private key of an identity in login keychain without raising any prompts. I am able to do this with system keychain (obviously with correct permissions and checks) but not with login keychain. It always ends up asking user for their login password. Here is how the code looks, roughly, NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassIdentity, (__bridge id)kSecReturnRef: @YES, (__bridge id)kSecMatchLimit: (__bridge id)kSecMatchLimitAll }; CFTypeRef result = NULL; OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)query, (CFTypeRef *)&result); NSArray *identities = ( NSArray *)result; SecIdentityRef identity = NULL; for (id _ident in identities) { // pick one as required } SecKeyRef privateKey = NULL; OSStatus status = SecIdentityCopyPrivateKey(identity, &privateKey); NSData *strData = [string dataUsingEncoding:NSUTF8StringEncoding]; unsigned char hash[CC_SHA256_DIGEST_LENGTH]; CC_SHA256(strData.bytes, (CC_LONG)strData.length, hash); NSData *digestData = [NSData dataWithBytes:hash length:CC_SHA256_DIGEST_LENGTH]; CFErrorRef cfError = NULL; NSData *signature = (__bridge_transfer NSData *)SecKeyCreateSignature(privateKey, kSecKeyAlgorithmRSASignatureDigestPKCS1v15SHA256, (__bridge CFDataRef)digestData, &cfError); Above code raises these system logs in console default 08:44:52.781024+0000 securityd client is valid, proceeding default 08:44:52.781172+0000 securityd code requirement check failed (-67050), client is not Apple-signed default 08:44:52.781233+0000 securityd displaying keychain prompt for /Applications/Demo.app(81692) If the key is in login keychain, is there any way to do SecKeyCreateSignature without raising prompts? What does client is not Apple-signed mean? PS: Identities are pre-installed either manually or via some device management solution, the application is not installing them.
