  3. 🗑️ Empty the Bin: After deleting files, don’t forget to empty the Trash on your Mac. Files aren’t fully removed until you do this.

2. Optimize Your Storage Settings

Optimizing your storage is an essential aspect of maintaining your Mac’s performance. Your Mac has built-in settings that can help you optimize your storage automatically, making it easy to manage and free up space.

1. Use iCloud Photo Library

Enable iCloud Photo Library in the Photos app. This uploads your entire photo library to iCloud. Once enabled, you can choose to optimize Mac storage. This option keeps smaller, space-saving versions of the photos on your Mac while the full-resolution originals are stored in iCloud.

Whenever you need a full-resolution photo, you can download it from iCloud.

You can also convert HEIC images to JPG on Mac to make them more space-efficient.

2. Use iTunes Match or Apple Music

Services like iTunes Match and Apple Music allow you to store your music library in iCloud and stream music when needed. With iTunes Match, you can access your music library on any Apple device and download only the songs you want to listen to, saving space on your Mac.

After ensuring your music is safely in iCloud, you can remove local copies from your Mac. When you want to listen to these songs, they can be streamed or downloaded as needed.

If you have music files in large formats like WAV, convert them to more space-efficient formats like AAC or MP3.

7. Automatically Empty Your Bin

To automatically empty the Trash (Bin) on a Mac, you can use a built-in feature of macOS. This can be particularly useful for managing disk space and ensuring your Bin doesn’t accumulate too many old files.

Remember, once items are automatically removed from the Bin, they cannot be recovered, so be sure that you won’t need these files in the future before enabling this feature.

Here’s how to enable the automatically empty the Bin feature on your Mac:

  1. Click the Finder icon in your Dock to open a Finder window.
