I am considering converting one of my Macs to a Windows only laptop (i.e. only have Windows 7 installed on the internal drive - achieved via Paragon CampTune software).

 

I will keep a bootable copy of OS X on an external USB drive.

 

My only concern is whether I will be able to update the EFI firmware if/when an update is released. If I boot from an external USB will I be able to apply such an update?

 

Also, does Apple software update alert you when firmware updates are available?

 

Thanks

    You can perform all of the same functions on your machine booting from an external drive.  So yes, you will be able to download and install any firmware updates using your external drive.  Software Update will inform you of any needed firmware updates.
