Be aware: do not skip MacOS full upgrades (as you might miss out crucial firmware updates)

Posted by jpluimers on 2024/04/08

One of the odd things with Apple computers it that firmware updates are part of the MacOS updates.

From this Dutch thread:

[Wayback/Archive] WheelieNick on Twitter: “@jpluimers Welke firmware precies weet ik niet maar je moet er vanuit gaan als je naar iets wat boven high sierra staat wil gaan dat je altijd eerst naar high siërra moet. Niet van normaal siërra naar big sur bijvoorbeeld. Ik doe trouwens altijd tussenstappen, dus van high siërra naar”

I have bumped into this myself where I skipped an upgrade, then the Mac would not recognise certain media formatted with Apple File System – Wikipedia using intermediate versions of MacOS.

The intermediate versions of MacOS had introduced some firmware changes the newer MacOS version upgrade did not apply.
