As a tech blogger, I don't have specific information about the missed calls between Mac and Ariana. However, I can guide you on how to check missed calls on an iPhone, assuming you have access to their devices. Here's how you can do it:
1. Unlock the iPhone: Use the passcode or the device's biometric authentication (Face ID or Touch ID) to unlock the iPhone.
2. Open the Phone app: Locate and tap on the green Phone app icon on the iPhone's home screen to open it.
3. Go to the recent calls list: In the Phone app, select the "Recents" tab located at the bottom of the screen. This will display a list of recent incoming, outgoing, and missed calls.
4. Search for Ariana's number: Scroll through the list and look for Ariana's phone number. If you know the approximate date or time of the missed calls, it might help narrow down the search.
5. Identify the missed calls: Missed calls are typically highlighted with a red circle or the word "Missed" next to the phone number. Identify the missed calls from Ariana's number in the list.
6. Count the missed calls: Count the number of missed calls listed under Ariana's phone number to determine how many times Mac missed a call from her.
Remember, accessing someone else's device without their consent is a violation of privacy. This answer assumes that you have appropriate permission or access rights to check the missed calls on their iPhones.
