You can’t select Mac or PC only yet. I hope it will come at some point too. The old forum used to do it, but there is no faciility here as far as i know.
I’d really love to have that ability back, + the coloured markups of what you had selected or not. Now my download centre is a mess, and it has become almost impossible to keep track on what you have downloaded or not. It’s almost like I’m considering buying each product at a time to make sure I download all the files I ought to have. And getting the Stephany bundle - forget it simply too many files.
On top of that no matter how many times I’ve selected Show 50 per page it still goes back to 10 next time I enter. Big time frustration!
