Windows Phone 8.1 might not be available for your phone just yet — but it will hopefully arrive soon — but Microsoft seems to be preparing everything for when the refresh hits your device. And, if you own a Windows Phone, chances are you’re using a PC; however, if you’re the exception, and your computer of choice is a Mac, you might want to update your Windows Phone app client.
The new version is available to download and Windows Phone 8.1 support is just one of the changes Microsoft added to the app. You will now also be able to drag and drop .DNG files to Browse Device UI, and there are also various user interface improvements. Consult your App Store app for the update or follow the source link below to grab and install the client.
