The usual course of action to fix Tuxera after a major MacOS software update is to just reinstall it. The drive is a sweet deal for the price + Tuxera, especially the fact that it doesn't care whether you use your Toshiba external drive or any other brand (boooo to WD and Seagate). I got my copy of Tuxera from purchasing Toshiba's external USB3.0 hard drives that included the said software, specifically the Canvio Connect II. Once you attached your NTFS hard drive thinking it will be a routine access to your files, you notice that it goes back to a 'read-only' file explorer view even if you have Tuxera installed. Upon completing the long wait of downloading the OS update and its installation, you may think at first that everything seems to work fine. With the release of MacOS Sierra by Apple, you might have opted to update your Mac machine with that new OS especially if your gadget ecosystem revolves on the Apple-sphere of things.
