I would like to play with my IMac on my Ps4 slim but unfortunately my IMac has no HDMI connection and therefore you can send me the right adapter and it would be good if the media market would be.
No, we can't send it to you. We're not an adapter trade, and not the media market. Buy it yourself!
Does your Mac have a DisplayPort connection?
My wife's got one (DisplayPort mini). An adapter from there on DVI-D we had to order on the Internet (DVI is now obsolete). DisplayPort / DisplayPort mini on HDMI had the miser and stupid expert of our distrust in stock.
