apple mail aborts after upgrading iMac to Sonoma 14.7.
iMac 21.5 2019 with 3.6 GHZ Quad Core Intel RAM 32GB
After I upgraded to comply with the security requirements Apple Mail starts and aborts after a few seconds flashing a red screen. All other applications work.
Any useful ideas?
iMac 21.5″, macOS 14.7
