Just installed an HP original cartridge. The first page printed fine, after which print density went down rapidly after just a few pages. I'm not sure whether it is continuing to deteriorate.
Essentially the same question as in this post:
But the answer obviously does not help, since mine is an original cartridge.

The black and white box is the latest toner if hp is still providing. I am just telling you if you think you got a toner that is defective you need to return it to place of purchase to have them replace it or give you your money back. The only way to get a toner to print darker is to use hp toolbox software which allows you to choose a higher density and to make sure econo mode is turned off. It may not be available for MAC systems. Assuming the previous toner worked fine then I would think the new toner has an issue and needs to be replaced.
