Even though I own a mid-2012 MacBook Air, I use it very rarely. So far I have installed a couple of apps, most of them that I have installed are apps downloaded from the official Store. I have installed Windows 8.1 on this MacBook Air and whenever I turn on this beautiful notebook, I boot into Windows to update the antivirus and other programs. This morning, while composing 5 useful free tools for dual boot users, I decided to install NTFS Free for Mac OS X, a free program that lets you read and write to NTFS USB drive from Mac OS X. After downloading the app from developer’s page, I launched the app hoping that it would launch the setup but I got a dialog with an error saying that “NTFS free.pkg can’t be opened because it is from an unidentified developer.” As you likely know, Windows 8 and above versions of Windows also include a similar feature called SmartScreen, which tries to block lesser known programs. But in Windows 8/8.1, you can simply click More info option and then click Run anyway button to proceed installing or running the program.
