+
+Here’s a step-by-step guide for installing and running **Apache Tomcat on macOS**:
+
+---
+
+### 1. Check Java
+
+Tomcat requires Java. Verify you have it installed:
+
+```bash
+java -version
+```
+
+If you don’t see a Java version (e.g., `1.8` or `11` or higher), install one. On macOS the easiest way is via [Homebrew](https://brew.sh):
+
+```bash
+brew install openjdk@11
+```
+
+Then link it:
+
+```bash
+brew link --force --overwrite openjdk@11
+```
+
+---
+
+### 2. Install Tomcat (Option A: Homebrew – easiest)
+
+With Homebrew you can quickly install Tomcat:
+
+```bash
+brew install tomcat
+```
+
+This typically installs the latest version (e.g., Tomcat 10).
+
+You’ll find it under:
+
+```
+/usr/local/Cellar/tomcat/<version>/libexec
+```
+
+Or if using Apple Silicon:
+
+```
+/opt/homebrew/Cellar/tomcat/<version>/libexec
+```
+
+Run it with:
+
+```bash
+catalina run
+```
+
+---
+
+### 3. Install Tomcat (Option B: Manual Download – official way)
+
+1. Go to the [Apache Tomcat website](https://tomcat.apache.org/download-10.cgi) and download the latest stable release (choose the `.tar.gz`).
+
+2. Extract it to a directory, for example:
+
+   ```bash
+   tar xvf apache-tomcat-10.*.tar.gz
+   mv apache-tomcat-10.* ~/tomcat
+   ```
+
+3. Start Tomcat:
+
+   ```bash
+   cd ~/tomcat/bin
+   ./startup.sh
+   ```
+
+4. To stop it:
+
+   ```bash
+   ./shutdown.sh
+   ```
+
+---
+
+### 4. Verify Installation
+
+Open your browser and go to:
+
+```
+http://localhost:8080
+```
+
+You should see the Tomcat welcome page.
+
+---
+
+### 5. (Optional) Add to PATH
+
+So you can run `startup.sh` from anywhere, add this to your `~/.zshrc` or `~/.bashrc`:
+
+```bash
+export CATALINA_HOME=~/tomcat
+export PATH=$CATALINA_HOME/bin:$PATH
+```
+
+Reload:
+
+```bash
+source ~/.zshrc
+```
+
+---
+
+👉 That’s it. Now you have Tomcat running locally on macOS.
+
+Do you want me to also show you **how to deploy a WAR file to Tomcat on macOS** after setup?
