Perhaps it would be helpful to share what has led to your 100% success rate, or, share what you feel might be the problem that appears to plague many of us.
I for one have had no problem with any OS upgrade in 25 years of Mac use, since my initial IIsi, hopefully through being careful with how I manage my machines, and diligent with sensible house-keeping and updating. Hence my surprise and irritation with this one.
So, I would love to have your opinion as to what you think is causing this unusual phenomenon of 'bricking' machines. And, of course, given your apparent Level 8 expertise, your recommended solution.
I've downloaded the standalone 10.11.1 update but am not minded to use it until someone explains why this relatively unusual problem is occurring, and some suggested steps to ameliorate the issue.
