For the past few weeks now, we've been hearing BlackBerry Link was soon to be updated with contact and sync improvements on Windows and Mac and it looks as though BlackBerry is in the process of updating the desktop app through their site right now, as there has been weird things going on for the past little while. At first, it showed v184.108.40.206 for Mac was available but the file suddenly went missing. Now when you go visit, the site has reverted back to v220.127.116.11 and the BlackBerry Link file is still missing, almost as if they went to release an update but then decided to roll it back but had deleted the previous version and now need to re-upload it again.
In any case, you can grab the download right now thanks to @Berryfornoobs who managed to catch the download when it was live. At this point though, we can't really tell if it was meant to be in the hands of users, so if you're trying this one you're doing so at your own risk and we're not sure what all has changed other than the fact that if your device is running BlackBerry 10 OS version 10.1 or later, you can now sync contacts between your device and your computer. You can grab this one or wait for the proper version to show up on the BlackBerry download page. Windows users, there an update coming for you as well.
