Someone above said that as long as you avoid unsupported actions, FMP 11.0v4 works with Mojave. I have huge databases of relatively simple information. A very large home inventory. Nothing posted online etc. So what kind of functions will make it crash. If this isn't possible, is there an open source data base that I can migrate my data too? FMP has just advanced WAY beyond what I need, but I don't want to loose the records or search ability of FMP
