I have a Mid-2012 15" MacBook Pro that I've just put a new SSD into.
I didn't format the SSD prior to putting it into the computer, my plan was to boot into "recovery mode" (not sure of Apple's term for it) by using command+R and running disk utility from there.
I want to load High Sierra onto the SSD, which I would install via creating a USB installer.
I understand that High Sierra runs best on APFS, but Disk Utility in recovery mode doesn't give me that option.
If I go ahead and install from the USB, will part of the install process format the SSD to APFS, or do I need to format the SSD to APFS prior using another machine capable of formatting drives to APFS?
