Bliss works extremely well on a Macintosh computer (and what doesn't). After you've created a Bliss account, follow the below setup instructions to begin using Bliss.
Step 1: From your desktop, click Go > Connect to Server in the menu bar
Step 2: Type in your Bliss URL. This will look like http://demo.storagebliss.com/bliss/
(change demo with your account name).
Step 3: Type in your Bliss username and password.
Step 4: Enjoy using your Bliss Storage account.
For just $5/GB a month you can customize your Bliss plan to get exactly what you need.
