After updating my OS to Big Sur, I tried cloning a repo. In order to do so, I apparently need to install command-line tools. However, on Big Sur, whenever I try to download command-line tools, I get this warning and no installation.

enter image description here

  • Check if you can use brew for the time being. Not a lot can be done for beta. How did you attempt to install the CLT ? Can you try downloading it from the website ?

  • I tried to install CLT from the popup that appeared when attempting git clone and then attempting to install it from the website. Brew worked just fine. Thank you! Aug 26, 2020 at 17:42

I fixed the same issue for me by downloading and installing the latest CLT package from https://developer.apple.com/download/more/

  • For some reason that didn't work for me. Only Home brew. Aug 27, 2020 at 1:08

    This worked great. With the macOS beta I wasn't able to get right version of command-line tools using the standard approaches. Big Sur beta has been a big pain.
