I’m using a Mac at my office and I have one comment for OS X: It’s not designed for multiple monitors.

Today I just figured out a way for it to have revolving wallpapers synced on both monitors, something that Windows 7 does out of the box and doesn’t take a free afternoon at the office to do.

Anyway, here are the instructions:

1. Grab some huge ass images those you’d like to use as your wallpapers. I’d recommend getting some from InterfaceLIFT.
2. Open up Photoshop, slice the image into two, left and right, 50% width each. I used Slice Tool because I’m making multiple wallpapers, but it’s up to you, you can just Crop and save also.
3. Setup two new folders, drop the left portion into one, the right portion into the other.
4. Right click on the Desktop -> Change Desktop Background
5. Click on the “+” button on the bottom-left, add the left folder, and the right folder. On the left screen’s dialog, choose the left folder; on the right screen’s dialog, choose the right folder.
6. Choose the respective image (i.e. matching pair) on each screen. Voila!
7. If you’d like them to revolve, select “Change picture:” then keep untick/tick until you get the matching pair. Close the dialog and you’re done!

That’s 7-step for you. On Windows there’s only 1 step.

I’ll lament later on how shitty OS X is for multiple monitors
