Hi, Ju.
Sorry I haven't replied before now. [and I'm also sorry this is taking so long and being so frustrating]
When I did the install the entire process only took an hour or so.
It shouldn't take a week to run each package file.
All Pacifist does is replace the PPC loader that isn't present in later versions of the Mac OS after Snow Leopard.
You should also shut down Pacifist after it's finished.
Another thing. Have you run software update?
The instaled version of LP is probably 8.0. The latest is 8.0.2. That may make a difference.
I am also unsure what version of the Mac OS you are running. If it's Mavericks then LP will not work.
Serial number is asked for when you run LP for the first time.
My suggestion. Close down Pacifist and then shut down your mac.
After restart try and run Logic.
[The program is installed in the Applications folder? If it's somewhere else it won't work. The Apps folder is the default, so if you ran the installer packages one after another everything should be in the right place]
Another thing to do is ight click the Logic icon in the apps folder and select package contents. See what's there and try and determine if everything is in there.
regards.
