Troubleshooting macOS

In this article:

• Your Apple computer has an NVidia GPU and Lightform Creator runs very slowly.
• You are unable to run Lightform Creator after installing it on your computer.
• You are using an external GPU and Lightform Creator starts with an error.
• Lightform Creator's layout is too small or too large.

Your Apple computer has an NVidia GPU and Lightform Creator runs very slowly.

Problem: Lightform Creator starts and runs, but it is very slow, even with an extremely simple project on a "Pro" Apple computer.

Solution: Disable your NVidia GPU. Alternatively, use an Apple computer that doesn't have an NVidia GPU.

Background information:

• Apple has discontinued support for most NVidia hardware on macOS 10.14 and higher. More information about this can be found on NVidia's forum (https://forums.developer.nvidia.com/t/faq-about-macos-10-14-mojave-nvidia-drivers/66379).
• If you’re experiencing low performance and you have a switchable GPU (such as on a Macbook Pro 15"), you can permanently disable your NVidia GPU so that the integrated Intel GPU is always used. On most macOS 10.14+ systems with NVidia GPUs this will result in a performance increase.

Instructions for disabling your NVidia GPU follow:

• Warning: This process requires the use of unsupported non-Lightform software called "gSwitch". You use this software at your own risk.

1. You should close/quit whatever applications are running on your system before performing these steps.
2. Download the gSwitch app .zip file to your computer. Click the "Download .zip" link on https://codyschrank.github.io/gSwitch/.
