Apple Mail not opening after macOS 15.4 update
I keep getting the spinning beach ball and I've tried all the remedies I can find online - safe mode etc. Nothing works. My online iCloud Mail is fine as is the iPhone. I don't know how to re-install the Mail app? Nor do I understand how to re-install the entire system (it's been a long time since I've had consider this)
