Firmware installation steps have been followed from About the Mini DisplayPort to VGA adapter firmware update - Apple Support
I have a mid-2012 Macbook Pro and wanted to install this firmware as a solution to the erratic connections and crashes I faced while connecting to external monitors or projectors using the Apple provided adapter.
1. Just before installation the error dialog shows
"This package is incompatible with this version of OS X and may fail to install."
It also provided options to "Cancel installation" or "Continue Anyways".
2. Continuing a forced installation eventually fails with warnings too !
Has this been solved or experienced by others? Any pointers, thanks in advance.
