Q: Mac startup graphics problem
Hi I have an iMac mid 2011 with Sierra installed. I'm experimenting an issue during the startup. When the progress bar reaches 1/3 of the total, it stops and appears a colored bar on the screen, and immediately later the screen goes black for a second, then come back to the progress bar screen and the Mac ends the startup successfully however. I've attached the photo where the colors bar appears. Thank you, Francesco

My 2011 27" iMac has been doing that for years and does not have any issues. As long as the computer boots up normally and runs fine, leave it alone and don't worry.
