For those few of you who dual boot between 10.11 & 10.6, or who have switched back to 10.6 from 10.11, what are your experiences with the startup process when 10.6 is once again the default (permanent) startup? Is it slower than it used to be, as some seem to think it is? Does the "El Capitan black" startup screen briefly appear before it changes to the traditional gray screen? Is the switch from black to gray (if there is one) inelegant / clumsy looking, as some (whose computers were affected) have said it is? I'm not talking about using the Startup Manager (option key) to switch from 10.11 to 10.6. I'm talking about when 10.11 is once again completely out of the picture (meaning its external drive is either turned off or erased), and 10.6 is the default (permanent) startup disk (again). I've read reports of all of the above happening when downgrading from Yosemite. Thank you.
