Spaces Icon

Go to your applications folder, find spaces and drag it to the dock.

 

i had the same issue. the manual/apple site made it seem like the spaces icon would already appear in the dock. I had to drag it there myself

 

It seems you only get it on a clean install (you don't on an archive/install), you can just drag the Spaces icon from the Applications folder to the dock to make it appear.

 

Spaces Icon Not on Dock

I followed your instructions but when I tried to "drag" the Spaces icon in applications, to the dock it did not work!!?? Any more suggestions? I have MacPro 2.4 with Snow leopard os x

 

Spaces Icon Not on Dock

I went to another site and found my mistake! Had to go to Applications/Utilities, and then "drag" the spaces icon from Utilities to the dock.
It worked!.

 

Just make a "hot corner" for spaces and forget about the icon Super fast that way...

I try to use the hot corner on the pc at work

 

. . . or use a hot key.
You can also put a Spaces drop down menu in the Menu Bar.
