Applying Updates with Windows Phone Connector
When updates are ready for your Windows Phone 7 handset, you should be notified on the device that this is the case. Head to Settings > Phone Update and check the Notify me when new updates are found and Use my mobile data connection to check for updates boxes to make sure that your phone will notify you. Note that these options will not download the update to your phone – you will need a computer connected to the web for that to be possible.
Updates will display notifications once or twice a day while they are available, and you can choose to ignore these and apply them later if necessary.
If you are able to apply the update straight away, however, connect your Windows Phone to your Mac via the USB cable. Windows Phone Connector should open – if not, open it from the Applications screen.
In the Devices pane on the left, click the device name, and select Install Updates. Alternatively you can open Device Options… and select Check for updates.
(Note that a device name can be set up in Windows Phone 7 Connector for Mac via the Device Options… screen.)
With the update detected and downloading, you must keep your Windows Phone 7 device connected to your Mac. Follow any onscreen instructions that are displayed, and very soon your update will be downloaded, installed and applied!
