Hi, thanks for your reply. I've tried everything. My last hard drive just died unexpectedly, which didn't give me enough time to backup on to my external hard drive, so I got an engineer to instal (he recommended it), a SSD drive, with a clean install of OSX 10.13.6 High Sierra. 8GB RAM. I was using Garageband version 10.0.3. I can't get Apple to help me with this, so I must be screwed. Apple should still have support in place for long-term users like me. I've been using these machines for many years, but when they go wrong, they really go wrong and Apple don't appear to be interested. I can't get any reasonable response from Apple. just patronising stuff which I just don't need. All I want to do is finish my musical projects in that version. I've downloaded Garageband from different sources, but they don't work either - no audio, no instruments, no effects and no loops - even though I installed them, they do not appear in the media browser, or the instrument lists, or the effects lists, or component lists. I just cannot fathom it out at all. At my wits end.
