One of the senior I help reports that on her 2011 MB Pro running El Capitan 10.11.6, Mail keeps crashing.
She will open Mail, read two or three incoming emails, click on the next email to read and Mail will crash. This happens repeatedly.
Each time Mail quits, in the report to be sent to Apple this is prominent:
Exception Type: EXC_BAD _ACCESS (SIGSEGV) Exception Type: KERN_INVALID_ADDRESS at 0X000000000018 Exception Type: EXC_CORPSE_NOTIFY
I Googled this and the only thing useful I found was the suggestion that perhaps this might be connected with SIP; we checked and her is turned on.
I told her, tomorrow morning, when her mails comes in, to restart in Safe Mode, read her email, and see if the same thing happens or not. Will report back with her results.
In the meantime, can anyone suggest anything to try that might fix this???
