Unable to connect to background process in compressor

What version of FCP/FCS do you have?

I've been having the same problems with Compressor: Unable to connect to background process ever since I upgraded to Leopard. It seems as if Apple disregarded users of FCP 4.5 when they made Leopard. Through a friend, I upgraded to FCP Studio 1 using FCP 5.04, Compressor 2.01, etc (all upgraded to present status). None of the stated Apple cures are working. Is there something I can do other than uninstall & reinstall the same software over & over? This is very frustrating!

You are not alone. I am having the same problem w/ Compressor. I have not upgraded to 10.5 yet. It has been working all along, and I am very careful NOT to upgrade... I LIVE by the "if it ain't broke, don't fix it" motto.

I am on my third reinstall in as many days of Compressor/qmaster... this is absolutely ridiculous.

Can SOMEONE find a solution please?!?

(And don't tell me to use another computer as mentioned in the last thread on this subject!!!)
Frustrated....

...AND... after my last RE-install... it STILL gives the same response...

"Unable to connect with background process"

UGHHHH!!!! [venting]

Same problem. Compressor won't connect to the background process. Using FCP 5.1.4 in FCS 5 on a G4 running Leopard.

Same problem as everyone else "unable to connect to background process" with Compressor 2. How can Apple ignore this continually? This is flawed software and should be replaced at Apple's cost.

Well, FCP 4.5 is 4-5 years old now. You can't expect them to support it forever.

Leopard only supports FCS 2 and FCS 1.5 (i.e. FCP 5.1.x) which explains why your problem wasn't fixed upon upgrading.

I used to have this problem with Compressor and solved it this way:

They seem to be many causes though, so I can't guarantee this will work for everyone.

open a terminal and type:

sudo /Library/StartupItems/Qmaster/Qmaster start

press return, relaunch Compressor and try again.

I am also experiencing the same problem and error message. Running FCP 5 and Compressor 2. I tried to above suggestion (QMaster privileges) but that did not solve it. Want to try the next suggestion (type in a terminal) except I have no idea what terminal we are talking about.
Any other ideas please?

The Terminal is located in /Applications/Utilities.

Have you tried this? http://www.digitalrebellion.com/compressor_repair.htm

And this is a last resort but not as painful as you'd think:

Tried the Compressor Software fix, but that did not solve the problem.
As for trying Terminal, I'm not sure I have the courage to type anything in there, as there is an ominous message of "losing data" if what I enter is wrong.

you would have to type an amazingly coincidental command. It's not like anything you type is going to delete a file. If you copy and past the text from the post above you'll be fine.

Ok, I entered the above code into Terminal, and received this:
Break on _THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___Y OU_MUST_EXEC_() to debug.

Problem remains.

Look, this is screwy. I too receive the "background process" message and I haven't found anything that's fixed it.

I've turned off the anti-virus program, tried a couple of the terminal approaches and, most importantly, I did everything detailed in the Mac Support "SOLUTION," trashing various files, reinstalling the designated programs and installing the new updates.

No change.

I mean, +come on+. There's an answer out there for me, right? Point me in the right direction.
