I am planning to follow the instruction from MacSale to add an additional SSD to a mid-2011 27" iMac (https://youtu.be/eFHvIrdm9So)
It will be placed under the optical drive.
I want to make this drive the boot disk and do a fresh install of macOS to this drive. However the video did not touch on this area.
Based on what I know, I think I can
1) Start up the system after the installation is complete.
2) After chime, I will use
Command (⌘) – Option (⌥) – R combination to boot into internet recovery
3) install macOS to the new drive
However I am not sure how to permanently boot from the SSD drive.
In summary, my questions:
a) Is my plan of 'internet recovery ' going to work?
b) how to permanently boot from the SSD drive?
