Beginning with Wunderlist for Mac version 3.0 we no longer support Mac OSX Snow Leopard (OS 10.6) or Lion (10.7). This wasn't an easy decision to make, but it allows us to improve the performance and quality of the app overall.
If you're still using a Mac with an OS version older than 10.8, and have no plans to upgrade, then we highly recommend using one of the following options instead:
- Use the web app at https://www.wunderlist.com in the latest version of Chrome or Firefox.
- Try our Wunderlist for Chrome Packaged app.
