Can't download GarageBand 10.1 update and app store keeps searching for updates. 10.10.3 Yosemite
I received a notice of a 10.3 update for GarageBand. When I pressed download, the app store starts seaching for more updates while the GarageBand download keeps cycling. I routinely add all such updates even if I don't use the application. Have tried numerous restarts and reset permissions without success. I am really disappointed to have a problem like this and it makes me wonder if my system has somehow become infected with something bad. It also now appears there may be a Yosemite 10.10.4 update, but this never showed up as an available update on my computer.
