Q: Bootable USB drive with Yosemite
Hi there
I've just got myself a new Macbook Pro and since there is an update to the Captain availaible I wanted to know whether it is still possible to create a bootable USB drive with Yosemite, which I got preinstalled on the machine. I wanted to have it in case there was trouble with El Captain, because I've heard some users may struggle with it.
I know it was very easy when Yosemite was still possible to download from the App Store but now there's only the Captain.
I am a completely new Mac user and I hope that it's possible to do that.
If it is - How do I do that then?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)

If you download the Yosemite installer again, you could save it on the Flash drive and make the internal drive the target. Done that way, the installer shouldn't delete itself when it's done. Indeed, that's one of the reasons I routinely create a bootable Flash drive because it not only makes troubleshooting a lot easier but allows a totally fresh installation on internal drives after it's completely wiped.
However, you may not be able to download Yosemite since it came on your Mac rather than having been upgraded to it. Under those circumstances, you could boot into the Recovery partition on the Flash drive (Option key down at the chime and pick Recovery associated with the Flash drive, not the internal). The OS X version you'd be able to install would be what's installed on the Flash drive.
