Allows you to set graphics preferences for macOS applications, and force use of external GPUs, even on internal displays.

This script requires the following specifications:

• Mac running external GPU
• macOS 10.13.4 or later

Note: Mojave has this built-in. For some reason, Mojave does not adhere to plist values anymore. For the time being, set-eGPU functionality will not affect apps on Mojave. This is odd even though it is documented in Mojave.

Install set-eGPU.sh:

curl -s "https://api.github.com/repos/mayankk2308/set-egpu/releases/latest" | grep '"browser_download_url":' | sed -E 's/.*"([^"]+)".*/\1/' | xargs curl -L -s -0 > set-eGPU.sh && chmod +x set-eGPU.sh && ./set-eGPU.sh && rm set-eGPU.sh

This will automatically install the latest version of set-eGPU.sh. Administrative privileges are required only for installation and software updates. All other script activity is performed in a user-privileged shell automatically.

Alternatively, download set-eGPU.sh. Then run the following in Terminal:

cd Downloads
chmod +x set-eGPU.sh
./set-eGPU.sh

On first-time use, the script will auto-install itself as a binary into /usr/local/bin/. This enables much simpler future use. To use the script again, just type the following in Terminal:

set-eGPU

An update for macOS Mojave is currently under R&D. It will happen very soon.

Set-eGPU makes it super-easy to perform actions with an interactive menu, and is recommended for most users. Providing no arguments to the script defaults to the menu.

For advanced users that may sometimes prefer bypassing the menu, the script provides convenient arguments in an attempt to be as user-friendly as possible.

Checks all available applications and sets their GPU preference to use eGPUs.

Checks specified application(s) and sets its GPU preference to use eGPUs.

Reads specified application(s) GPU preferences.

Resets GPU preferences to system defaults for all applications.

Recover original untouched macOS configuration prior to script modifications.

Run your application and check Activity Monitor > Window > GPU History (⌘ + 4) for GPU statistics.
