Hi there,

My first post. I had the same problem - when I clicked on submit in Compressor the drop down box appeared and in the Cluster box it said "none" and the submit button was greyed out. I've fixed mine and it works perfectly now. Here's how:

Go to System Preferences and select Sharing. A box appears with your computer's name at the top and a list of things you can share. Select File Sharing and to the right, it will say something like: FTP Access:On with a message underneath which contains your computer's IP address e.g 10.6.4.3. Make a note of this number.

Open Compressor and go to Compressor > Preferences. The Preferences Dialogue Box appears and at the bottom it says: Enter IP addresses or ranges for manually selected computers. Click on the + button at bottom left and then enter your computer's name and the IP address you noted earlier. Online will probably appear under status.

Next time you start a job in Compressor and click on submit the drop down box will now say This computer in the Cluster box and the submit button will no longer be greyed out - BINGO

this is what I did and it worked for me. Good luck.

Fingers Lee
