  1. Ok I know this process but why doesn’t apple make it straightforward ? Like an option to create an installer with one click ?

  2. I just love when 9to5Mac has a video exactly on what I am needing to do. Sooooo easy to follow, vs. googling it.

  3. Jeff, how did you format your “Macintosh SSD” the way you have it? It’s orange, and says SSD instead of HD.

  4. I have OS X Yosemite on my 12 inch MacBook. I can do this with El Capitan and then have both Yosemite and El Capitan? All I would need to run El Capitan is that thumb drive?

  5. I loaded the installer onto an external SSD drive, I restarted and started the install process but when I tried to install I got an error message ‘Disk Locked’ so I cannot install High Sierra to that external SSD drive. Any ideas what I have done wrong?
