How to apply patch in Drupal 8?

@mac 

To apply a patch in Drupal 8, you will need to follow these steps:

1. Download the patch file and save it to your computer.
2. Navigate to the root directory of your Drupal installation on your local machine using a command line interface such as Terminal on macOS or Linux, or Git Bash on Windows.
3. Run the following command to apply the patch:

1

patch -p1 < /path/to/patch/file.patch

Replace "/path/to/patch/file.patch" with the actual path to the patch file on your local machine.

1. If the patch was applied successfully, you will see a message indicating that the patch was applied. If there were any conflicts or errors, you will see a message indicating that the patch failed to apply.
2. If the patch failed to apply, you may need to resolve any conflicts manually by editing the affected files. Once you have resolved any conflicts, you can try applying the patch again.
3. After applying the patch, you may need to clear the cache in Drupal to ensure that the changes take effect. To do this, go to "Configuration" > "Performance" and click the "Clear all caches" button.
4. It is a good idea to test your site after applying a patch to ensure that everything is working as expected.
