When I delete a photo from Lightroom Classic and I want to also delete from my computer file it does NOT delete the file from my computer. It used to do but not recently.

I use a Macbook Pro. I import from a folder on my Macbook into Lightroom Classic. While editing I want to discard some photos from Lightroom but also from my Macbook . The option is there to delete from Lightroom AND my laptop but it doesn’t delete the file from my laptop. It used to do on earlier versions of Lightroom (which I know not) but it hasn’t done for quite a while. What I have to do now ouside Lightroom is go into my laptop and delete to unwanted photo files.
