EFI Firmware Version Confusion

Hi,

I have some trouble with my keyboard and trackpad from time to time.

Now, I checked the EFI Boot version of my MacBook Air 4.1 (mid 2011)

I have mba41.0077.b14 installed but Apple Website (EFI- und SMC-Firmware-Updates für Intel-basierte Mac-Computer - Apple Support) says mba41.0077.b12 is the right one.

I'm confused due b14 looks newer than b12.

Can someone advise?

Stig
