When saving configs with the NVIDIA WEB DRIVERS Boot Flag selected the saved config files reports: Configuration file corrupted. Not able to load it. This happened in MB 9.1 and is also the case in 9.2. I've attached two similar config files, one with NVIDIA WEB DRIVERS Boot Flag (Multibeast-with.mb) and one without (Multibeast-without.mb). --OMK PS: This is my first post on a this forum ever. Working on a User build report, this issue was just a minor hiccup in getting the Hackintosh build I'm typing this on.
