dotnet: command not found in Mac

Make sure your macOS version meets the prerequisites

https://docs.microsoft.com/en-us/dotnet/core/macos-prerequisites?tabs=netcore2x

If it does, then after installing via the installer, in a new terminal run this command

ln -s /usr/local/share/dotnet/dotnet /usr/local/bin/

Then try dotnet --version

hopefully that should work

EDIT:

You might need to add x64 like so:

ln -s /usr/local/share/dotnet/x64/dotnet /usr/local/bin/

For Mac M1

sudo ln -s /usr/local/share/dotnet/x64/dotnet /usr/local/bin/

If you add symbolic link to /usr/local/bin/ but you get file exist error.

You can delete the dotnet file at /usr/local/bin/

or

at you finder Shift + ⌘ Command + G and type /usr/local/bin/ , delete the dotnet file in finder.

Just another way how to successfully install dotnet on a Mac: using Homebrew, you can simply run:

brew install dotnet

to have it install. Advantages include automatic updates via brew upgrade and less to worry about permissions or any of the workarounds mentioned as solutions before me.

You can find the formula information here: https://formulae.brew.sh/formula/dotnet

If you are using the dotnet x64 installer for mac which can be found here , use this command

sudo su
ln -s /usr/local/share/dotnet/x64/dotnet /usr/local/bin/

I solved by editing ~/.zshrc

#Add .NET to $PATH

export PATH="/usr/local/share/dotnet:$PATH"

Run sudo ln -s /usr/local/share/dotnet/dotnet /usr/local/bin/ in the command line, you then should be prompted for your password. This is the solution that worked for me on Mac OS Catalina.

.NET 6.x on MacOS I had to run with updated path

ln -s /usr/local/share/dotnet/**x64**/dotnet /usr/local/bin/

Run with sudo if you getting a permission error.

I solved it this way:

Add entry to .bash_profile

Before:

export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/opt/gradle/gradle-4.10.2/bin

After:

export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/opt/gradle/gradle-4.10.2/bin:/usr/local/share/dotnet
