Garageband was not able to install the new sounds

Fixing permissions with Disk Utility will only fix the /Library permissions, not your temporary directory.

Occasionally it can happen, that the ownership for $TMPDIR is wrong. Then the installer cannot write there or delete older, partial downloads.

You can make yourself the owner of your own $TMPDIR again using the shell command below: It sets the ownership of $TMPDIR and all subfolders to your own userid . This can only be done from an administrator account.

sudo chown -R $UID $TMPDIR..

I found the folders and I found some packages in there. I was able to double click and install the 2 packages but when I went back to GarageBand it was still trying to download and it took like 15 minutes before the download crapped out again. My progress bar got way further this time.

Does anyone have applecare? Has anyone called apple? WHat do they say?

This worked for me!! You also may need to open folders that don't allow permission. You right click and show info. Then click permissions at the bottom and set to read & write.

You also may need to install everything thats there and then click the app again until it possibly fails again...Then run any new pkgs it installs... What a pain in the ...

Thank you!!

I'm sorry - that all sounds really complicated to me. I don't really know how to do all that

just follow the fprefect444 solution. The double-clicking on PKG files is very easy and just takes a bit of clicking. We uh shouldn't have to do it but whatever ...it works until one of the 100,000+ employees over at Apple fix this for us.

Scary man, but I'll try. Just follow it to the letter? No surprises?

This was a clean install of Yosemite on an iMac Mid 2011 2.5Ghz

The first time I launched Garageband, I immediately got the message "Garageband was not able...."

I did use the advice from Leonie and fix the permissions of the temp directory with sudo chown -R $UID $TMPDIR..

That did change one thing, instead immediately giving me the message "Garageband was not able...." it did download something.

It was only when I entered the password that the message came back again.

I tried fperfect444's solution, but when I click on the packages I get "can't be installed on this disk. A qualifying copy of Logic or MainStage or GarageBand was not found".

Seems to me, from all of these post, Apple would be more on top of this.

A qualifying copy of Logic or MainStage or GarageBand was not found"

If the AppStore does not find Garageband as installed, you may need to rebuild the SpotLight index for your System drive. That is where the AppStore is looking, to see which versions of applications you have installed.

See this link: Spotlight: How to re-index folders or volumes - Apple Support http://support.apple.com/en-us/HT201716

OK, so in the end, all I did was delete the Application, the Application Support Garage Band Folder and two references to GarageBand that I found in the hidden folders "private/var/folders". I'm not sure if it helped or not but I did re-index spotlight and I did use the command sudo chown -R $UID $TMPDIR.. That I got from Leonie. Hope this helps someone out there.

This problem is a huge pain in the *ss. After 2 hours of messing about, deleting hidden files and having crashes on restart.... I finally got it to install. REALLY APPLE?!?! Did you even test this software before you released it? GARAGEBAND FAILS ON INSTALL!! You can't even use the basic program if you are doing a new install.

This worked for me:

Open App Store

Go to the 'featured' page

On the bottom right of the page it should have a small list of purchased apps, open garage band from there and it should work.

If GarageBAnd came preinstalled with MacOS X 10.7 or later, t should still be showing on your Purchases tab at the App Store. You may be seeing an "Accept" button. Click that to associate GarageBand with your Apple ID.

Then try to install the additional content again. If it still does not work, try to boot into Safe mode:

Hi I was able to resolve this problem for now after having the same problem following a similar process to the whole /private/var/folders SoftwareUpdate cache erase. I have a feeling I was having issues with the OSX allowing the default administrators be given access to restricted folders within the garageband process itself. I'm not sure if its something Apple will deal with but I have similar problems in unrelated projects with Yosemite. Now what I did was simply manually find the Content packages. For me they were located here: private/var/folders/38/8sz_xtgj37qgx011vd99kr6c0000gn/C/com.Apple.garageband10 after you reach this folder by using finder "Go -> Go To Folder" menu option click through the hierarchies until you reach com.apple.garageband10/com.apple.MusicApps/audiocontentdownload.apple.com/lp10_m s3_content_2013 this is where all the garageband content packages are, now if it is a fresh install the very first pkg should be GarageBandCoreContent.pkg. Click this and follow installer instructions and you will now have access to garageband. After you have done this the content collapses and you can go back and install the premium content the same way. Good luck!
