macbook pro 13.3" retina, osx 10.9.4, 2.4 ghz intel i5, 8gb ram. so i recently was installing the old garageband legacy midi sounds and samples. i was all the way through and was installing the "world music" portion last. it froze twice attempting to run scripts. i gave up and force quit wasn't working so i restarted the computer by pressing the power button. i was finally able to restart without the computer telling me an active installation was taking place and deleted the excess world music files and everything was working fine. so a few hours later I'm trying to install TX16Wx and it's telling me its "waiting to other installations to complete"... not completing... im assuming the mac still thinks its trying to install the garageband files. how do i force it to stop trying to install it? what do i do? please help me, i don't want to drive and hour and a half to the mac store. thanks guys.
