GarageBand 10: 'more sounds' purchase stuck in perma-download
I've already seen several unresolved threads on this issue, but wanted to bump it up in case somebody out there has found out anything.
On our new iMac, my daughter chose the in-app purchase of extra sounds for $4.99. That was 3 days ago. It's been downloading ever since.
According to the dialog box, the app must remain open for the download to continue, so we've done that. Yet the progress bar never makes it past about 20%, and every few seconds the estimated time remaining fluctuates wildly between 7 and 50+ hours, usually hovering somewhere around 30. We have noticed that certain loops that were originally greyed-out are now available, but, like other folks have noted, "slide guitar," "vocals," and "clavinet" remain grey.
I have received no receipt from Apple confirming the purchase, nor is there any record of the purchase in our App Store purchases tab, nor have I figured out any way to determine what specific additional content is actually included in this endless, ginormous download. It is disconcerting that this content isn't simply available via the standard methods. If in-app purchases are the wave of the future, fine, but at least let me know what I'm buying.
Has anybody else been able to figure out what's going on with this? Thanks!
