When I try to send an email to one specific group in Contacts, my iMac does not pick up those addressees. I have to go to Contacts and click on Send an email to ... . It works fine on other groups. This may occur because, in trying to sync my groups with iPad and iPhone, I got duplicates. The duplicate of the specific group is empty, but I can't figure out how to delete duplicates.
iMac 21.5″, macOS 13.4
Start with this of M1 or M2 Mac...
On your Mac, choose Apple menu > Shut Down.
Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
Press and hold the power button on your Mac until “Loading startup options” appears.
Select a volume.
Press and hold the Shift key, then click Continue in Safe Mode.
The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.
Restart normally.
Start with this if IntelMac...
Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
Any help here?
