Ha. I guess I am more or less at the same point as you. The cells display correctly, I can click on one, it open the NSColorPanel, I can alter the color. The table is filled through a data provider, not bindings, because I have to do a lot of work in case of modification (e.g. if the user alters the 86 at the second row to 90, the 86 of the third row should change also).

Yes, that I knew, because it is mentioned explicitly in the documentation ("override CopyWithZone if you have iVar objects because the default implementation just copies pointers"). Fortunately, my custom cell has only one iVar which is its NSColor, so it does not too intricate!
