My Mac Mini updated itself to Mavericks 10.9.2 now recording drops out in GB after 10 bars or so. I'm using the internal sound.

    Are you using the latest GarageBand (10.0.1)?


    Did you allow GarageBand to update its data files (about 1GB) when you did the update?  Did it do something like a rebuild of its data structures when you first opened the updated version?

    Thanks sberman! The GB version is 10.0.1. Is there a way to request a GB data file update? There weren't any requests denied during the update.


    Last night ran activity monitor, disn't see anything that seemed to be gobbling resources, went back to GB recorded a track with no issues. Had a friend over tonight, got 10 bars into a song, recording 2 tracks and had the dropout. Restarted, re-recorded 2 tracks go to 20 bars or so and dropout.


    Have the bit depth at 24 and have the rate at 48 I'm pretty sure. I don't think internal (line in)  samples any quicker.


    I'm an Apple newbie and certainly did not expect this! I had buffer size control with WIN XP and with little tweaking would only get a dropout if a disk scan or virus scan decided to steal rescources.


    Is there a way to try a different buffer size?

    You can try deleting the preferences file as detailed here under "Delete the user preferences":



    If you cannot find the library folder in Finder, you can locate it by holding the option key down as you press "Go" in the menu bar.

    Thanks again sberman! Deleted the files, restarted and recorded 2 tracks, no glitches, 120 bars. Sure hope this works!
