Sure, I can guide you through the process of making a podcast using Apple's GarageBand, which is a free app available on all Apple devices. Here's a step-by-step guide:

1. **Create a New Project**: Open GarageBand and select "New Project". Choose "Voice", which is the best option for podcasting.

2. **Set Up Your Project**: Name your project and set the tempo, key, and time signature. For most podcasts, the default settings will work fine.

3. **Record Your Podcast**: Click on the red record button to start recording. You can see the audio waves form as you speak. Press the space bar or click the stop button to stop recording.

4. **Edit Your Podcast**: GarageBand has a range of editing tools. You can cut, copy, paste, and move sections of audio. You can also adjust the volume, add effects, and more.

5. **Add Music or Sound Effects**: If you want to add music or sound effects, you can drag and drop them into your project. GarageBand has a library of royalty-free sounds you can use.

6. **Export Your Podcast**: Once you're happy with your podcast, you can export it. Go to "Share" in the menu and select "Export Song to Disk". Choose the quality and file type (usually MP3 for podcasts), then click "Export".

7. **Publish Your Podcast**: To publish your podcast on Apple Podcasts, you'll need to submit it through Apple's Podcasts Connect portal. You'll need an Apple ID, the RSS feed for your podcast, and all your podcast details (like title, description, and cover art).

8. **Submit for Review**: Once you've entered all your information, you can submit your podcast for review. Apple will check your podcast to make sure it meets their guidelines. If it does, it will be available on Apple Podcasts within a few days.

Remember, creating a great podcast takes time and practice, so don't be discouraged if your first few attempts aren't perfect. Happy podcasting!
