Gads, don't get me started on SPI software upgrades on the Mac Book Pro. Serious cramp in the calvins. Forced non-down-gradable (sp?) OS because of that.

- Wowfunhappy 5y agoCould you expand on how this causes problems? As far as I'm aware, this has never prevented e.g. downgrading to an older version of macOS. (I assume I would know because I downgrade everything to OS X 10.9.)
- Something1234 5y agoWhy do you downgrade so far?
- Wowfunhappy 5y agoA 2012 Macbook Air, a 2014 Macbook Air, and a 2014 Macbook Pro. The 2012 Macbook Air was upgraded to Mojave at one point before it ran Mavericks. I admittedly don't know what OS the two 2014 Macs were running before I bought them in 2020.
