I want to make more space on my camera SD card. I can delete them via the camera which is tedious. How can I do it via my Mac
If the photos are already on your Mac - and you have a back up - the simplest answer is to format the card in the camera. It takes seconds and wipes the entire card. Many photographers do this after every transfer as they feel it improves the functionality of the card.

Simply plug the camera's SD card into an appropriate slot on your Mac computer - not sure which kind or year you own; but if there is a SD slot, use that insertion point, if not a SD-USB adapter can be used. The card should then be seen as mounted in Finder (see pic below from my MBPro) - open the DCIM folder which likely will contain sub-folders - pics can be easily deleted from these various folders.

After you deleted the pictures, did you empty the trash?
I'm not exactly sure what the crteria are, but for some external devices, deleting files just seems to mark them as deleted but doesn't free up the memory space until the trash is emptied.
Or, as already suggested - if you don't want to keep any pictures or data on your SD card, formatting the card in the camera will also delete everything on the card.
I can tell you that reformatting the card in the camera after downloading it's contents is the preferred method used by professional photographers I know. It ensures the card stays correctly formatted and reduces the need to remove the card.
