Question: Create bootable USB with Yosemite
Both I and may daughter are running El Capitan on our Macs. However, she wants to play Sims3 on her laptop. Regretfully, the developers of the game have failed to make it work under El Capitan and later. And their option to download updated versions also fails.
So I thought I'd create a bootable USB stick with Yosemite, as the game worked just fine for her when she used that OS version. And I've hit a brick wall.
I have duly downloaded the "Install OS X Yosemite.app" from App store. When trying to launch it, I get error message that it's too old to be opened on my OS X version (El Capitan). Fair enough.
So I have tried every method I have found online: the Terminal, the Disc Utility and Disk Drill.app. In all cases, all required files seems to be copied over to the flash drive (16 Gb, USB 3).
But neither the disk utility nor booting with options key down shows the disc. It's invisible.
Can someone shed some light on this?
Thanks in advance,
Mac Pro, OS X El Capitan (10.11.3)
