Hi,

Last week my iMac (mid-2010 model) began restarting for no reason. After doing some diagnostics I was able to determine it was my mail causing the issue.
I'm unable to open the mail to do any further diagnostics within the app. Before I did the step below I would open the mail and the iMac would just restart instantly.

So far I've tried to do the following

~/Library/Containers//Data/Library/Preferences - look for the plist and drag it to desktop and restart the mail.

When I reopen the mail now it will import 130,000 and once it has done that my iMac just restarts again.

Does anyone have any ideas on how to fix this issue?

Thanks in advance,
Stuart
