I. If the patch 1.22 download won't start for you, try getting it using the other three servers.
II. If "war3.exe cannot be found", download the missing update (Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)) from here.
And here is the changelogs, correct me if i'm wrong:

from players and other observers using chat commands:
/showminimapsignals and /hideminimapsignals.

The good news is, with Warcraft patch 1.22 the Mac user will now be able to hear "FIRST BLOOD" and the other anouncer sound when playing Dota-Allstars. We also have in game option to always see the health bar, nice! But there's also some issues that will occur when we are playing Dota-Allstars with Patch 1.22. The most reknown is the problem with the rune and lag. I hope this won't stop IceFrog to release Dota-Allstars 6.53 next week.
I'm still don't know how to upgrade to 1.22 without connect to server (offline), i know a lot of you want to do it. If some of you know how to do it, i will be happy if you share it in here :)
Edit: Add more information
Update: Upgrade again to Warcraft III 1.23 Patch ;)
