Reset device > device blocked from internet because Apple deems its os/software unsafe > Can't access app store to update device to safe/up to date os > have to manual download install for midway update > then update via app store to current distro.
Absolutely nightmare. Zero info from apple that this was the upgrade path/how it had to be done.
Psychotic. Huge reminder why I generally reject all apple work. Company is a nightmare to service machines for.
Also lol the 2012 intel Mac was being repurposed because the 2 year old Mac airs battery was rooted and it worked worse than the 2012 rig. Both lived their lives permanently plugged in like desktops being used for web browsing and email.
