Logic Pro X: missing plug-in.. error or bug?

In logic pro x 10.1.1 i can only add a limited number of software instrument tracks: 2 or 3.

after that in the plug in button appears an orange circle with an exclamation mark. Hoovering over the button shows the text "missing plug-in:plug-in-name". However the same plug-in can be loaded on other software instrument tracks without any trouble.


I just recently discovered the problem, in the past i could load software plug ins without problems. I have an Imac i7 3,5, 16 Gb ram. Although i recently migrated the software (my whole system) from an MBP i5, 2,53 I didnt have any trouble on that machine.


Is this a bug? Any help is really appreciated .

Using Migration with Logic Pro has always caused many Users issues..... mainly due to unusual permissions related problems..


This is why I recommend always installing Logic Pro from scratch on a new Mac including all content......


But as a possible fix.. Create a new admin account on your Mac (System Preferences/Users and Groups.... ) log out of your current account and log into the new one... and then run Logic from within that new account and see what happens...

Try trashing Logics' preferences in the old user account. To find them you need to make the user Library visible first:

Open your home folder (/Users/"yourusername") in the Finder. Depending on your Finder settings, this may be as easy as simply opening a new Finder window. Otherwise, choose Home from the Finder’s Go menu (Go > Home); or press Shift-Command-H.

Still in the Finder, choose View > Show View Options (or press Cmd-J).

Near the bottom of the resulting View options palette is a setting called Show Library Folder. Enable this option. Your Library folder is immediately visible.

Close the View options palette.


Now, in the user Library folder, open the Preferences folder and chuck out all com.apple.logic… files.

Ok so far so good, thanks for your replies everyone. After removing and reinstalling Logic pro X and the additional content and prefs the problem seems to be solved, but somehow now all my apple loops arent available in the loop browser...


Strangest thing: after deleting Logic Pro X, prefs, loop index files, repairing perms and reinstalling AGAIN. Logic didnt do its normal AU plug in refresh round.

Plug ins seem to be installed ok right now but.....

I'm out of luck here


BTW - should this be in a new thread?
