Relocate Sound Library to existing sound library

I'm afraid I don't get it. You say your sound library was on your external drive, now you want to move it to your external drive? So you want to move it to the place where it already is? Why, if it is already on the place where you want to move it to?

micdim, Logic does this for a different reason. If you did a fresh reinstall of macOS (or you migrated your data and apps to a new Mac, which obviously would have a fresh install of macOS), then the installation receipts for Logic Sound Library might be missing from your Mac. That's why the library is marked as not installed, although you can actually access the content on the external HD. It's a common issue.

We've discussed and experimented with receipt "transplant" in another thread. One of the users even uploaded an archive with the LPX sound library receipts from his system, and apparently also came up with a method of copy-pasting them (hence my term "transplant") 🙂

You may find it by browsing this thread: Logic Pro X sound library status not updating

Just copy-paste the symbolic links in [Your Mac Mini's System HD]/Library/Application Support/Logic folder to [Your iMac System HD]/Library/Application Support/Logic/ folder. Also, delete any existing sound library folders from /Library/Application Support/Logic/ folder on the iMac. Hint: these would be folders with the same names as symbolic links you copy-pasted there.

I don't think there will be issues since you migrated your data from Mini to iMac, and so the user name (I assume) is the same.

OK, nice of you (or more likely: a mistake) to mark my question as the solution, but as I understand it now, from the answer by JotaGi, you did not have any content already on your system disk, just on the external, and Logic wasn't seeing that?
Anyway, good it was solved, see if you can unmark my question and give the green star of thankfullness to JotaGi.

Or else, host(s), could any of you do that?

Hi JotaGi,

What if the Username and hard drive have different names. I tried that, and logic seems to use the external location files, however it still shows that the content is not downloaded.

Any ideas why Logic would be using the external files, but shows they are not installed?

Thanks for your great input here.

Not a problem, micdim. It's not that complicated, actually. Just a note that this "receipt transplant" would work if you previously had the sound library downloaded and installed in full, because the receipts provided in the thread linked above are for the whole library.

However, if you look at this technique on an abstract level, it proves that the shortcomings of Logic developers when it comes to sound library management (related to library relocation) are fixable. All you need is a copy of your sound library installation receipts and a bit of patience.

All good Eriksimon, the red star of helpfulness is quite enough 🙂

Wow thanks JotaGi!

Looks a little complicated, but I'll check it out!

Great input, and thanks again!

On my way out, however how many receipts are there?

and thanks again. Fantastic!

No worries. From my own receipt folder, there are 1320 receipts related to Logic Sound Library.

Fantastic! Downloaded and all good now. Wow thanks to everyone!

Most welcome, micdim! Enjoy 😀
