Logic Pro was not able to complete the download? Sound Library

DATE TODAY: AUGUST 9th 2022 - Ive noticed a large amount of these posts are spread across many years, so some of the fixes may not work anymore and some of the advice isn't valid anymore. That said, this fix may not work forever either, so I guess in short: Pay attention to the post dates for issues as generic as this, because reasons.

A Work Around Tested On 10.7.3 on macOS Monterey 12.4.

1. Open Logic Pro.
2. Upon seeing the "Resume content download?" pop-up, choose CANCEL. Do not choose either of the other two options. They will just loop the cycle over and over.
3. After hitting CANCEL, Create a new, Empty Project". Choose a 'Drummer' track type with 'Songwriter' as the drummer type, and hit "Create". Hopefully this will bring up a Some additional content is needed for this project. Do you want to download it now? pop-up, but it's not required to get this to stop looping.
4. If the "Download it now?" pop-up DID come up, click No/Cancel and then Close out of the project immediately. Do not save changes on exit.
5. Re-load Logic Pro. It should be clear this time around, or at least flushed so that you can retry the downloads with a new cache.
6. There is no number 6. OR IS THERE.......

Good luck, I hope this helps a few of you.

I got this error and could do nothing to fix it until I updated Logic Pro to latest version (for me that was from 10.5 to 10.7 - now sound library updates fine.

I think the error was misleading - the download had fully completed - it was unable to install the new sounds in my older version.

Caused me lots of time spinning on it.

Thank you so much!! It works now.

It seems like the only way to fix this issue is to update logic to its latest version which is 10.7.4.

As mentioned in a previous comment, I was able to resolve this issue by simply updating my Logic version. Although I thought I was on the latest update of Logic, I was one version behind, and updating to the current version of the app let me download everything without a problem.

Apple should definitely change the error message, but in the meantime, see if you're on the latest version!

This appears to be affecting a large amount of people, and so if it's affecting you too, I strongly urge you to file a "Radar" with Apple so that they are made aware of the problem and fix it.

This is different than some of the other feedback pages I've seen in the answers section.

I am facing the same exact issue.

Were you able to resolve it?

Hi there, it looks like this is an issue on Apple's side (i.e. some sort of a server error or something like that). There'd been another question just like yours a few weeks ago, but I don't recall what solution worked in that case exactly.

If you can, try using a VPN to make your Mac look like it's connecting to Apple's content distribution servers from a different location (ideally, from another continent, say, Europe, if you're in the US, and vice versa).

I have already tried turning off the firewall and still it shows the same error.

Also I've tried downloading it via Ethernet and a different Wifi connection both and still no resolution.

If this is at Apple's end then I hope they fix it soon.

Hi everyone, It is 28 Aug and I have latest Mac OS and logic 10.7.4 and still have the same issue, has anyone have any solution?

Try to download the library in smaller chunks by Open Sound Library Manager and choosing (checking) the missing libraries manually.
