Macbook Pro 13' 2015 with OS X Yosemite on board. I've been trying to install OS X El Capitan, but always get the following message: 'This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading.' By the way this is not a date time issue, date is correct on my computer. The mismatch is occasional which proves that El Capitan is not all that different from Yosemite.) An alternative to reading the whole book is to use it as a reference while doing the hands-on exercises in the much briefer 'Teach Yourself Visually OS X El Capitan.' Part One: The OS X Desktop 1.

We have an iMac that is barely still compatible with El Capitan. Right now it runs Mountain Lion okay, and actually it has a smaller partition on the hard drive for another clean installation of Mountain Lion that we don't really use.

I have an El Capitan boot USB drive and an El Capitan install app, and I was thinking about using one of those to upgrade the clean install partition to El Capitan to see how it performs, but I'm hesitant and want to make sure things wouldn't be messed up.

So first of all, does this sound like a good idea? Second, would it be better to boot into the USB drive and choose to install to the clean install partition or should I put the install app on the clean install's Application's folder and run it from there?

Also would doing this risk causing the Mountain Lion restore partition to be deleted? Are there risks of things being messed up, not being able to make Mountain Lion the default boot partition, or other weird things El Capitan would do to the main partition?
