macOS Sierra 10.12.4 Build 16E175b seeded…

Apple today seeded the fourth beta of an upcoming macOS Sierra 10.12.4 update to developers. Their latest build is 16E175b.

The first thing I spotted was that two of the three new plists, added in Build 16E144f for Kaby Lake processors, will be removed by an installation script:


Source: Tools/cleanListSUConstructed (paths shortened).

The third one is still there:


Another thing is that /S*/L*/Extensions/eficheck.kext is being removed. Along with all the whitelists at: /usr/libexec/firmwarecheckers/eficheck/whitelists/

The NVRAM variable SkipBluetoothAutomaticFirmwareUpdate is now also removed.

Looks like Apple is preparing for a release…

  1. Seems to bring new firmware along for the 2010 MacBook (7,1) – MB71.0039.B10 is flashed atop the previous MB71.0039.B0E (which Apple still mentions as the latest for this model).
    Other models updated as well?
