user5906: I'm following the instructions laid out in https://docs.plutus-community.com/docs/setup/MacOS.html to setup my intel Mac (Big Sur) dev environment for cohort 3 of the pioneer program and having issues.
I've successfully completed steps 1-8 (in the link above): I have nix installed, rebooted computer and the cloned plutus code.
When I do Step 9, which is
nix build -f default.nix plutus.haskell.packages.plutus-core.components.library
I get
error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override
adding the suggested tag seems to build fine so I can get by this step.
But then I can't get step 10 to work.  When I enter
nix-build -A plutus-playground.client
it replies with
error: attribute 'plutus-playground' in selection path 'plutus-playground.client' not found
I'm new to nix and cabal so don't really know where to start to resolve this.  I see lots of other files named pluts-xxx in the plutus directory, but nothing related named "plutus-playground"
Can someone please tell me what do I need to run or load in order to get this to work?
Thanks

user5896: In step 7, there should be a 2nd line instructing you clone the plutus-apps.  Change plutus.git to plutus-apps.git in step 7 to clone it, then run the playground nix-build from the top of that second repo.
