Interesting I was expecting a drive icon to appear on Desktop for camera. Nothing, but opening the Mac app Image Capture, allows the downloads and recognises both cameras and allows me to download to Mac to a folder named after the camera. So now I bet all my cables work! Learn something new every day!
I have a small typo (mistake) in that I should have written the white ends are originally USB 1.0, but many manufacturers use it for USB-2.0. this may help: https://www.geeksinphoenix.com/blog/post/2014/01/12/How-to-tell-what-type-of-USB-connector-you-have-by-color.aspx
Check your menu settings, for PC Connection Mode. It sounds like you have it set to USB RAW CONV. / BACKUP RESTORE -- this is what it should be to copy the settings to your computer. To transfer images, set it to USB CARD READER, then some of your programs will be able to transfer the images.
