Why Apple Intelligence Takes Up So Much Storage on Your Mac ?

Apple Intelligence can use a surprising amount of storage on your Mac.

With macOS 27, Apple says its AI features require up to 14GB on Macs with an M3 chip or later and at least 12GB of unified memory. Other compatible Macs may require up to 8GB.

At first, that might sound like another system feature consuming valuable disk space. But it is actually one of the best things about Apple Intelligence.

A large local footprint means that many AI tasks can happen directly on your Mac instead of sending everything to a remote server.

Why does Apple Intelligence need so much storage?

AI models need to be stored somewhere.

Cloud AI services keep their models inside large data centers. When you send them a request, the processing happens on someone else’s computer.

Apple Intelligence takes a different approach. Apple installs on-device models and supporting resources on your Mac so that many features can run locally.

Apple does not provide an exact breakdown of everything included in the 8GB or 14GB requirement. The company also describes Apple Intelligence as a collection of models and specialized components, rather than one large model file.

The storage can therefore include language models, image models, feature-specific resources and other assets required by the system.

It is also an “up to” requirement. The exact amount may vary depending on your Mac, language and available features.

That storage is being used for privacy

When an AI model runs locally, your request does not need to leave your computer.

This can provide several benefits:

• Your personal data can remain on your Mac.

• Some features can work without an internet connection.

• Responses can begin without waiting for a remote server.

• Apple does not need to process every request in the cloud.

According to Apple, many Apple Intelligence models run entirely on the device. This includes tasks such as determining which notifications should receive priority.

Using several gigabytes of disk space is a reasonable trade-off when that storage lets your computer process personal information locally.

Your Mac already contains your messages, photos, documents and calendar. For many tasks, the safest place to process that information is on the same device.

Does everything stay on your Mac?

No.

Some requests require more processing power than a Mac can provide efficiently. In those situations, Apple Intelligence may send the request to Private Cloud Compute.

Private Cloud Compute uses larger server-based models to complete more demanding tasks. Apple gives Image Playground as one example of a feature that may use this infrastructure.

Apple says data processed by Private Cloud Compute:

• Is used only to complete the request

• Is not stored after the request

• Is not made accessible to Apple

• Is not linked to your Apple Account

This is a stronger privacy model than sending every request to a traditional AI service. However, it is still important to understand the distinction.

Apple Intelligence is designed to prioritize on-device processing, but not every feature runs entirely on your Mac. Apple also says that some features using server-side models have daily usage limits.

You can see when Apple Intelligence sends requests away from your Mac by enabling the Apple Intelligence and Private Cloud Compute report in macOS privacy settings.

What about searching across your files?

This is where Apple Intelligence still feels limited.

On its current feature availability page, Apple mentions:

• Natural-language search in Photos

• AI search for HomeKit Secure Video

• Intelligent file and folder name suggestions in Finder

What Apple does not list is a general Apple Intelligence feature for searching across the contents of all your Mac files.

There is also no searchable screen memory that lets you retrieve something you previously saw, heard or worked on.

Spotlight remains useful for finding files through filenames, metadata and indexed text. But it does not provide the same kind of private memory across documents, images, videos, audio and previous screen activity.

Fenn brings private AI search to your Mac

Fenn is designed to fill this gap.

It lets you search inside the files and folders you choose, even when you do not remember the filename or where something was saved.

Fenn can also create a searchable Screen Memory. This helps you retrieve something you previously saw, heard or said on your Mac.

You could search for:

• A document based on what it discusses

• A specific moment inside a video or audio recording

• An image based on its visual content

• Something you saw on your screen several days or months ago

• A conversation or presentation you heard during a meeting

You control how much Screen Memory is retained based on your available disk space.

Fenn supports macOS 14 or later. With its default local models, your files, searches and screen history are processed directly on your Mac.

Local AI should use your computer

For years, software companies moved more data and processing into the cloud. AI gives us an opportunity to reverse part of that trend.

Modern Macs contain powerful chips capable of running useful AI models locally. Using several gigabytes of storage to make that possible is not wasteful. It is a practical use of the hardware you already own.

Apple Intelligence uses local storage to bring more intelligence into the operating system.

Fenn uses the same local-first idea to make your files and digital memory searchable.

In both cases, the principle is simple: if your computer is powerful enough to process your data, your data should not have to leave it.
