You’re not alone—quite a few users moving to an iPhone 16 Pro with a MacBook running macOS Sequoia (15.5) have reported delays and phantom/missed calls when using FaceTime and regular calls through the Continuity feature, especially if the MacBook is asleep or has just been woken up
Here are some steps with the highest reported success rates:
• Restart Both Devices: Simple, but worth trying—turn both your iPhone and MacBook off and back on.
• Sign Out and Back In: Open FaceTime on your Mac, sign out of your Apple ID, then sign back in. Some users found this fixed call-receive issues.
• Update Everything: Double-check both your iPhone and MacBook are fully up-to-date, including any minor software updates or patches released after macOS 15.5.
• Check Handoff/Continuity Settings: On both devices, verify that Handoff is enabled (System Settings > General > AirDrop & Handoff on Mac; Settings > General > AirPlay & Handoff on iPhone).
• Check Call Settings: On iPhone, go to Settings > Phone > Calls on Other Devices and ensure your MacBook is enabled and set to receive calls “When Nearby.” On your Mac, in FaceTime settings, make sure “Calls from iPhone” is checked.
• Check Wi-Fi/Bluetooth: Both devices should be on the same Wi-Fi network, with Bluetooth enabled.
• Flush DNS or Try a New User Profile: Advanced, but sometimes helps—resetting networking settings on your Mac or creating a new user account to see if the issue persists.
• Contact Apple Support: If nothing works, there may be a deeper bug in Apple’s cloud/account side—or something unique to your setup. Some users report Apple Support was able to fix the issue by “resetting” FaceTime or your ID on their end
