<p>The following git repo has the latest information on setting up your environment in Mac M1. I personally followed this tutorial and worked perfectly. I suggest you delete everything you have done before and start from scratch following this link. <a href="https://github.com/renzwo/cardano-plutus-apps-install-m1/blob/main/README.md" rel="nofollow noreferrer">https://github.com/renzwo/cardano-plutus-apps-install-m1/blob/main/README.md</a></p>

I did update with your suggestion for M1 based nix.conf file but used the cache suggested for the Plutus Starter. See updated logs above

I also see file descriptor error when running nix-build on Plutus-Apps

I dont think you should use the plutus-start-project for now , the repo they have on github is not updated , and you have to do a lot of things to fix it to make it run right now.

Well I followed the instructions for M1 above for Plutus-Apps and reinstalled nix as well. However, I am still seeing the invalid file descriptor errors as indicated in my update above.

I did install ghc before so perhaps that might be having an effect. I think with nix this should not be a factor however

perhaps it has something to do with this issue that mentions both bad file descriptors and too many open file descriptors? https://github.com/NixOS/nixpkgs/issues/101459

The following git repo has the latest information on setting up your environment in Mac M1. I personally followed this tutorial and worked perfectly. I suggest you delete everything you have done before and start from scratch following this link. <https://github.com/renzwo/cardano-plutus-apps-install-m1/blob/main/README.md>

> **Comments:**
> **username_0**: Ok, did you get try this with plutus-starter project?  
> **username_0**: I did update with your suggestion for M1 based nix.conf file but used the cache suggested for the Plutus Starter. See updated logs above  
> **username_0**: I also see file descriptor error when running nix-build on Plutus-Apps  
> **username_1**: I dont think you should use the plutus-start-project for now , the repo they have on github is not updated , and you have to do a lot of things to fix it to make it run right now.  
> **username_0**: Well I followed the instructions for M1 above for Plutus-Apps and reinstalled nix as well. However, I am still seeing the invalid file descriptor errors as indicated in my update above.  
> **username_0**: I did install ghc before so perhaps that might be having an effect. I think with nix this should not be a factor however  
> **username_1**: I dont really know what exact error you are getting , hit me up on my email shanyuzhang123@gmail.com. We can hop on a zoom or google meet call. I can try to help you set up from there,  
> **username_1**: actually we can meet on discord if you want Shan#7955  
> **username_0**: Sounds good, I will send you email and hop on discord as well  
> **username_2**: Your answer could be improved with additional supporting information.
