Git Ignore (global)

Create the file ~/.gitignore as shown below

# Folder view configuration files
.DS_Store
Desktop.ini

# Thumbnail cache files
._*
Thumbs.db

# Files that might appear on external disks
.Spotlight-V100
.Trashes

# Compiled Python files
*.pyc

# Compiled C++ files
*.out

# Application specific files
venv
node_modules
.sass-cache

# Teraform files
# Local .terraform directories
**/.terraform/*

# .tfstate files
*.tfstate
*.tfstate.*

# Crash log files
crash.log

# Ignore any .tfvars files that are generated automatically for each Terraform run. Most
# .tfvars files are managed as part of configuration and so should be included in
# version control.
#
# example.tfvars

# Ignore override files as they are usually used to override resources locally and so
# are not checked in
override.tf
override.tf.json
*_override.tf
*_override.tf.json

# Include override files you do wish to add to version control using negated pattern
#
# !example_override.tf

# Include tfplan files to ignore the plan output of command: terraform plan -out=tfplan
# example: *tfplan*

followed by running the command below, in terminal:

$ git config --global core.excludesfile ~/.gitignore

to not track files that are almost always ignored in all Git repositories.

Or simply download macOS specific .gitignore maintained by GitHub itself and put contents of it to ~/.gitignore.
