Is my multibit working?

[btcomg]

Hello I was running bitcoin-qt on windows and now I'm using Multibit on mac because someone told me I hadn't to download the full chain but I've tried some stuffs and I don't receive anything so is multibit really working ? Can someone send me something to check it's ok? (I can send you back then if you care)
