Q: MacBook Air EFI Firmware Update 2.9.1 fails to install

I recently got the MacBook Air EFI Firmware Update 2.9.1 in the App Store. The strange thing is that I never saw the 2.9 update everybody is mentioning.

After installing the update and rebooting its still showing as an update in de App Store. So I tried reinstalling it again. Still the same problem.

In system information its still showing Boot ROM Version: MBA41.0077.B0F

Anybody knows how to install it?

MacBook Air (11-inch Mid 2011), OS X Mavericks (10.9.4)

Same issue sadly after many hours of researching, I have come up with nothing that works. Anyone have any ideas? Anyone at Apple maybe?
