What about 3.4.4? It worked for me until I tried uploading a texture and a sound clip of under ten seconds. Then the viewer crashed repeatedly. A couple of weeks ago, i attempted to download this or an updated version and was given the notice: Sorry but this version is not compatible with the mac. So now i am wondering, has LL given up on macs and decided PCs rule? Of course, maybe this is just a knee jerk reaction on my part. For goodness sakes, folks, it seems there are some bugs in these new viewers to work out, such as mac compatibility, as well as mac compatibility when various hardware and software are in use. Hardware such as headsets and printers. Software such as well, plugins and whatnot.
