How do I install gSwitch on macOS?

Install via Homebrew with 'brew install gswitch' or download the .zip from the releases page and move gSwitch.app to your Applications folder. If it doesn't start, allow it in Security & Privacy settings.

Does gSwitch work on MacBook Pro 2020 or newer?

No, gSwitch is only for dual-GPU MacBook Pros (2011-2019 models). Apple Silicon Macs from 2020 onward don't have discrete GPUs, so the tool is incompatible and archived.

gSwitch vs gfxCardStatus: which should I use?

gSwitch is free and archived, while gfxCardStatus might offer more features or updates. For older Macs, gSwitch suffices for basic control, but if you need ongoing support, consider alternatives like gfxCardStatus.

How to force integrated GPU only with gSwitch?

Select 'integrated only' in the menu bar or run 'gswitch --integrated' in the terminal. This saves battery by preventing discrete GPU use, but external displays will automatically switch back to discrete.

Why is gSwitch archived and no longer updated?

gSwitch is archived because Apple's transition to Apple Silicon removed discrete GPUs from MacBook Pros, making the tool obsolete. The developer hasn't worked on it in years and no further development is planned.

Can gSwitch permanently disable my discrete GPU?

No, gSwitch cannot permanently disable the discrete GPU. It only temporarily switches to integrated mode, and attempting permanent disablement could brick your computer, as warned in the FAQ with a linked Apple StackExchange post.

What is gSwitch?

gSwitch is a macOS menu bar application that allows users to control which graphics card their dual-GPU MacBook Pro uses. It solves battery life problems by preventing unnecessary use of the power-hungry discrete GPU and works around buggy graphics drivers on some models. The project is now archived as newer Apple Silicon Macs no longer have discrete GPUs.

Target Audience

Users of older dual-GPU MacBook Pros (2011-2019 models) who want to extend battery life by controlling GPU usage and avoid graphics driver issues.

Value Proposition

It provides simple, free control over GPU selection that Apple doesn't offer natively, with both GUI and terminal interfaces. Unlike system defaults, it lets users force integrated GPU usage to maximize battery life.

Overview

macOS menu bar app that allows control over the gpu on dual gpu macbooks

Use Cases

Best For

Extending battery life on older dual-GPU MacBook Pros
Avoiding graphics driver glitches on specific MacBook models
Forcing integrated GPU usage for light computing tasks
Monitoring which processes are using the discrete GPU
Automatically switching GPUs when connecting external displays
Managing GPU power consumption via terminal commands

Not Ideal For

Users with Apple Silicon Macs or any Mac without a discrete GPU
Projects requiring active maintenance, bug fixes, or compatibility with macOS versions beyond its archival
Users who need to permanently disable the discrete GPU for hardware modifications
MacBook models older than 2011 running modern macOS, due to removed APIs

Pros & Cons

Pros

Battery Life Optimization

Forces use of the integrated GPU to reduce power consumption, directly addressing the discrete GPU's high energy drain that ruins battery life, as highlighted in the README.

Driver Issue Workaround

Helps avoid glitchy and buggy graphics card drivers on some MacBook models, providing a practical solution where Apple hasn't fixed issues, as stated in the project description.

Simple GUI and Terminal Control

Offers a menu bar app with integrated-only, discrete-only, and dynamic switching modes, plus terminal commands (--integrated, --discrete, --dynamic) for flexible management.

Process Monitoring

Shows dependent processes using the discrete GPU and hungry processes waiting for it, allowing users to identify and manage GPU-heavy applications effectively, as explained in the FAQ.

Cons

Archived and Unsupported

The project is no longer maintained or updated, as Apple Silicon Macs eliminated the need, leaving it outdated with no bug fixes or support for modern macOS versions.

Hardware and OS Limitations

Only works on dual-GPU MacBook Pros from 2011 to 2019, and may not function on older models with modern macOS due to removed APIs, as noted in the legacy section.

Cannot Permanently Disable GPU

As admitted in the FAQ, gSwitch cannot safely disable the discrete GPU permanently; it only switches back to integrated mode temporarily, with risks of bricking the computer if forced.
