Apple releases firmware update for new MacBook Pro
Apple on Wednesday released MacBook Pro Flash Storage Firmware Update 1.0, which, according to Apple's website, is for mid-2015 MacBook Pro models. The website also sates that the firmware update fixes an issue that "may cause data corruption."
In case you're wondering, about the "mid-2105" part: When Apple releases new Macs, it uses identifies when the model was released with "early-," "mid-," or "late-," labels. The 15-inch MacBook Pro currently for sale by Apple is labeled mid-2015. So if you have a MacBook Pro from mid-2014, you do not need to install the firmware update.
The release period label isn't marked on the MacBook Pro product box or on the MacBook Pro itself. But you can find it if you look up About This Mac.
The 1.9MB update is available for download from Apple's website.
