I don't understand why my backspace key does not work on my Mac. I have several Mac computers (10+) and my backspace doesn't work. Why did I reinstall all of these to see if it is an issue on the ones without backspace? It works flawlessly on my new system. Please help and thanks. My Backspace key doesn't work on my Mac: Aug 12, 2022 — Hi I was trying to find out if my backspace would not work. If you could tell me that it's not an option I would be very pleased to hear it! I can't believe that my backspace key in Mac doesn't work! I have a mac running Mac OSX 10.6.4 (Snow Leopard) and can't get it to work! Furthermore, I tried to install the backspace-key-mod-kit, and it seems to be working fine, but then I do a copy and paste, copy a tab's contents from one window to another, paste into a code editor and I still have no go. Furthermore, I'm not sure if all these are related, it took me a while to find the problem. Is there anyway you can help me with how to stop my backspace key working? — Naveen Singh What's not working I used to hate my backspace key. It was a constant annoyance. Now I use it for deleting to delete on an external hard drive, and it's great. What's up with the backspace? What's wrong with mine? If a Mac has a backspace (delete) key problem, or other key/button problems, there may be an issue with the USB cable. Some people have reported that backspace does not work on a Mac, and there have been a few theories on what may be causing the issue. One of the more common theories is that the USB cable may not be properly installed. (See Troubleshooting Apple USB cables.) You can test if your USB cable will work with this one. A good test is a full reset to Mac OS X. Then perform the following steps: Open your computer. Disconnect your USB cable. Open the Accessories folder and enter “Reset” (without quotes). Press Enter. Press and release Option + F2. Click Command + R when your system appears. When you see this screen, just press and release Alt + F2. Repeat step 5 (Reset). When you see “System Recovery Options”, press Option + R.
