Firstly, the premise is a hard one to make happen, I'd like to point that out, but I'm going to just go with it for now:
Without the Greeks to influence and colonize Macedonia (there were Greek colonies in the area which proved a great way for Koine to spread into Macedonia and become the common language of Macedonians by Alexander's day), what will be left is a culture that is living on borrowed time. With whatever pressures are present to their south seeping northward, certainly influencing them in a similar way as the Greeks did just by geographic locality. Then there are the Illyrians and Thracians to the North. And THEN, if butterflies don't go too crazy, there are still Persians (or another group from that area that will fill a similar niche) that moved in and took over Macedonia. Without the Greek city-states, the Persians will likely keep a firm grip on their European holdings, including Macedonia.
Now, as for the greater world at large, without Greeks to colonize the Mediterranean, you see vast changes throughout history. The Phoenicians will gain a virtual monopoly on western trade, and will control the coasts of Sicily, Cyprus, North Africa, and Spain without contestation. This, I think, will play to the benefit of the Etruscans, who I believe, without the Greeks would have remained the dominant group in Italy. Without the devastating defeats the Greeks inflicted upon them in the early 5th century BC, the Etruscans would have continued to have hegemony over Latium and Campania. How they fair against the Celts when they migrate in is up for debate, but I think we can assume that Rome will simply remain an Etruscan satellite. I actually think we could see Etruscans colonizing the areas in Gaul that the Greeks colonized given enough time.
And I remember seeing someone mention something about coins, so let me just set this straight: Coinage was invented by the Lydians, an Anatolian people who came to power around the same time as the Neo-Assyrians and the Medians. Coinage will spread probably in the same way as OTL.
