Wadjet's latest, Primordia [1], is really good, especially if you are into postapocalyptic scifi. (Windows, but runs perfectly on Macs via Wineskin.) Retro graphics, looks like it was made cirka 1990. There is also their earlier cyberpunk game, Gemini Rue [2], also great.

There is also Machinarium [3] by Amanita (of Samorost fame). No dialogue, so less like MI, but still one of the finest games ever made.

To add to the Wadjet Eye love, I also enjoyed the entire Blackwell series.

And Machinarium is definitely charming.
