garageband restore sound library not working
I am using yosemite 10.10.1 and garageband 10.0.3 on a mid-2009 macbook pro with 4GB and also on a mid 2007 imac with 2GB
I have attempted to "restore sound library" several times on both computers. they spend a long time lownloading and then they spend a long time installing, but nothing has changed and the "restore sound library" is still on the menu.
I am asking about this because I think something may have gone with my yosemite install. Apple says mavericks and yosemite have the same minimum requirements, but performance and stability have both taken a big hit with the yosemite install. The imac is almost useless. Lots of beachball, lots of mysterious crashes. mavericks ran just fine on both machines.
Can somebody tell me if this is a garageband issue or an issue with a bad yosemite install.
thanks
