I just bought a new iMac- 21 inch, 500gig, and 4 memory. I am still very new to macs. On my macbook pro on the dock is an application folder. The iMac does not have this on the dock. I have been using this folder to open programs. How do I get an app folder on the dock of the iMac. Also will I be able to share iPhoto over the network? It is on the iMac but did not come with the macbook Thanks.
