14 DAY TRIAL // Soon after users started reporting the availability of a new firmware update for their Mini DisplayPort-equipped Macs, Apple posted the Mini DisplayPort to VGA Adapter Firmware Update 1.0 as a (downloadable) standalone installer on the Support section of its web site. Now, those who haven't yet updated via the Software Update mechanism also have the option to download the standalone installer for the new firmware update.
Yesterday, AppleInsider was reporting that the company behind the Mac operating system was actively distributing a new firmware update attempting to fix flickering and blank video issues on the latest generation Macs equipped with MiniDisplay Ports. Only users connected to external displays using the company's Mini DisplayPort to VGA Adapter could see the firmware appearing in their Macs' Software Update. Now, anyone who thinks they might need the update can just grab the new firmware and install it.
According to Apple, “this firmware update addresses intermittent flickering and compatibility issues such as no video on some external displays when using the Mini DisplayPort to VGA Adapter on your Mini DisplayPort enabled Mac.”
“The Mini DisplayPort to VGA Adapter firmware update will be downloaded to the Utilities folder and will automatically launch to update the firmware on the Mini DisplayPort to VGA Adapter,” Apple explains. Your Mini DisplayPort to VGA Adapter must also be plugged into your Mac and a compatible VGA display, Apple outlines, while the Mac power adapter must be plugged into a power outlet.
