Trying to run commands sam build --use-container and sam local start-api, both return errors about docker being unreachable, although it is running and active. I am using iMac with M1 processor, this could be the issue, but I could not find anyone else having this issue specifically on Apple Silicon.
The directory of the project is under /Users/, thus it is by default included in docker shared directories.

Error: Running AWS SAM projects locally requires Docker. Have you got it installed and running?

Answers
The most likely cause of the errors you are getting is that you are using an incompatible version of Docker for your iMac with M1 processor. The sam commands you are trying to run require Docker to build and run your serverless application locally, but they may not work well with the Docker version you have installed.
Explanation
According to the official documentation of AWS SAM CLI, the sam build –use-container command builds your application inside a Docker container that mimics the Lambda execution environment. The sam local start-api command runs your application locally by using a Docker network. Both of these commands depend on Docker to function properly.
However, not all versions of Docker are compatible with the iMac M1 processor, which uses a different architecture than the Intel-based Macs. The M1 processor uses the ARM64 architecture, which is more efficient and powerful, but also requires different binaries and libraries than the x86_64 architecture used by Intel.
As of now, Docker has released a preview version of Docker Desktop for Mac with Apple Silicon support, which you can download from here. This version is still experimental and may have some bugs or limitations, but it should allow you to run the sam commands without errors. Alternatively, you can try to use a different tool to run your serverless application locally, such as LocalStack, which does not rely on Docker.
Docker Desktop fixed this issue with their latest release:
Make sure your Docker Desktop is updated.
My company development has been on hold due to this issue for over a week now. I can confirm that the latest patch 4.13.1 addresses the issue.
Once updated to 4.13.1, be sure to restart docker fully.
