Hello, all! First post here... Ok, Im having some problems. Im running a 2.5GHz intel core 15 Mac, with 4GB 1333 MHz DDR3 memory here with Mountain Lion. I've used garageband for years. This is my second iMac, as the first had to go to internal mic problems. Now I have this nice new one, and I'm already running into problems. iMovie has massive latency issues, but more worrying, garageband has run into a problem. Ok, so when I spice a piece of audio, that spliced piece then produces a quite loud 'pop', or 'tick' at the beginning of each spliced part. It doesn't show up in the audio itself. It can happen randomly, with all spliced parts, or just some. Its always at the beginning. This is now happening on once fine projects that I was using in my previous version of garageband on my old Mac? I've searched everywhere on the net for a remedy for this. I've tried: Turning off all applications apart from GB (Thinking it maybe a memory issue) Pulling out all external devices Re-starting computer 'Sharing' the track to see if the pops are on the finished product. They are. I want to re-install GB, but have no idea how I would do that? I have TONS of project that would severely mess me up if they become corrupt. Really old ones as well. Anyhow, ANY help with this is much appreciated, so thanks in advance!
