Otherwise, replacing the drive means a visit to an Apple store or 'service provider'. It requires a special 'pentalobe' screwdriver for some of the screws, however. iFixit, which provides guides on how to replace parts for a huge range of hardware, describes the difficulty of the replacement as 'moderate'. The SSD in a MacBook Air cannot be easily replaced by the user - although some sites such as Everymac and iFixit have detailed instructions on how to do it. Otherwise it will show a dialog box indicating that the firmware was successfully installed. If the drive suffers from the data-loss problem then it will direct the user to the support page, where they have a number of options to get the drive replaced. If the Firmware Update app does appear, install it (which requires being connected to a power source) and run it. The app will check the drive and install new firmware. If no update called 'Firmware Update 1.1' appears, the computer is unaffected.

To test whether the drive is affected, users should launch the Mac App Store (on the top left-hand menu of the screen) and choose 'Updates'. Although it does not specify the manufacturer, a teardown by iFixit last year suggested that it has a Sandforce controller and is made by Toshiba. 'Certain' 64GB and 128GB flash storage drives 'may fail', Apple says in a support page about the problem.
