The Etrecheck report is below.
In the interim, I was able to shave off 20 seconds or so from the startup time by doing a few cleanup tips particularly stopping Flash
Problem description:
I have an early 2011 Macbook Pro 2.7 GHz Intel Core i7 that began taking a minute to startup after upgraded to Yosemite awhile back. After T/C w Apple Support, just successfully upgraded from 4 gb to 16 gb memory. Yet the startup is still slow. Next?
