Next, download the free DoubleTwist app to your Android phone. Then use a USB cable to connect your phone to your Mac, and follow the instructions on the screen to mount your phone to your computer. Once your phone is mounted, click on your device (in the lower left menu) to open the sync options. You can sync all of your music and videos at once, or you can pick and choose different playlists to sync. You can also drag and drop files and photos to your device.
Syncing nonmedia files, such as documents and spreadsheets, between your Android phone and your Mac is easy, thanks to cloud storage services. In this example we'll use Dropbox (and assume that you already have it set up on your Mac), but you can use any service that appeals to you, such as Box, Google Drive, SkyDrive, or SugarSync.
Download the Dropbox app on your Android phone. From there, sign in to Dropbox with your account info. Thereafter, any file you place in your Dropbox folder will be synced between your devices automatically.
As on the iPhone, you can choose to have Dropbox automatically save and sync the pictures you take on your Android phone (you get an extra 500MB of storage space if you enable this option). This option is similar to Google's option to automatically upload photos taken to your Google account, and it can be a little creepy at first (maybe you don't want those photos to be synced off your phone), but it can be useful if you lose your device.
The easiest way to sync everything from your Android device to your Mac is to use Google's own apps for email, calendaring, photos, and contacts. If you do, you can enable syncing from your Web-based Google account to your Android device by going to Settings > Accounts > Google and tapping your Google account (under Accounts).
From this menu, you can toggle syncing of various Google services--including Google Chrome, Photos, Google Play Books, Google Play Magazines, Google Play Music, Google+, and Picasa Web albums--on or off. You can also choose to sync the Internet, an interesting feature that syncs your Google search results across devices.
