Question: Mac Sierra - Mail app crash when composing and adding addresses
My Mac Mail app always crashes very consistently when I am composing an email message and try to add an alias to the sender fields. It happens on adding one particular alias only. For others it works. So far I have just searched the forums and have not found anything that is close to this issue.
Below is my Mac spec.
Processor Name: Intel Core i5
Processor Speed: 2.3 GHz

Total Number of Cores: 2
Memory: 16 GB
System Version: macOS 10.12.6 (16G1212)
Kernel Version: Darwin 16.7.0
MacBook Pro with Retina display, macOS Sierra (10.12.6)
