If you're experiencing any of the issues listed below, a defective, unsupported, or incompatible graphics processor (also called a graphics card, video card, or GPU) or graphics driver could be the issue. The solutions listed in this section can help you resolve the following issues:
Mac Os X Video Card Driver
If you're experiencing any of the issues listed above, or Lightroom Classic isn't accessing your graphics processor and your graphics card meets the minimum system requirements, update the graphics driver.
When upgrading the graphics card driver, it is recommended that you remove all previous versions of the graphics card driver from your computer before installing the new one. This is called a clean installation.
Multiple graphics cards with conflicting drivers can cause problems with GPU-accelerated or enabled features in Lightroom Classic. For best results, connect two (or more) monitors into one graphics card.
If you're using more than one graphics card in Windows, your high-end card might not be set as the primary card. To disable the lesser of the two cards, use the Device Manager on Windows. In the Device Manager, right-click the card's name and choose Disable.
Out-of-date drivers and operating systems can cause a variety of issues and are one of the first things to check when a game is having problems. The instructions below will help you check and update your drivers.
A Software Update is an incremental update of the Mac OS and its applications, Security Updates, device drivers, and firmware updates. For Blizzard games, it is important to download and install all software updates, as our games are designed for the latest version of the supported system requirements.
DisplayLink Manager is a new way to enable your DisplayLink dock, adapter or monitor on macOS platforms. It's an application that combines our latest driver with features that streamline the setup of mutliple displays up to 4K.
I installed the 7.5.30 driver that NVIDIA said I need for the Quadro 4000. I'm waiting for that card to be delivered but the 7.5.30 driver works with the NVIDIA GeForce GT 120 1024 MB as well as the 4000.
I found 5 drivers in /Library>Frameworks that are not supposed to work with a 4,1. They were the only drivers there and I have no idea why they were there. I trashed those. Now there are no drivers in the Frameworks folder.
Nvidia GPUs receive driver updates soon after each version update of OS X. Only one driver is released by Nvidia and it includes support for all of their modern GPUs. You will not find individually named Nvidia drivers for OS X, they are all titled "Quadro & Geforce Mac OS X Driver Release xxx.xx.xxxxx".
BTW, you're not supposed to manually shuffle drivers around on macOS. The Mac itself is perfectly capable of doing that for you. All you need to do is install the NVidia web driver. Leave the existing Apple drivers in place. There is a switch inside the web driver control panel to enable switching between the two driver sets. Moving things around manually is likely to break that.
To use Elgato Video Capture for Windows, you will need to download both the Driver, and the Software. After downloading, run the driver installation and follow the instructions. You can also update previous driver versions with this application.

Parallels Desktop has no access to the Mac's device's physical graphics cards. Instead, Parallels Display Adapter driver (which is part of the Parallels Tools installation) interfaces with virtual hardware and provides 3D acceleration features. The actual acceleration is achieved by translating Direct X commands from the guest OS to the OpenGL API on the macOS side.
Most Mac computers have an integrated graphics card, which is built into the motherboard and shares memory with the CPU. It provides a more economical alternative to the standalone card, known as "discrete graphics" or "dedicated graphics." In this case, Parallels Desktop will use the resources of the built-in Mac built-in graphics.
Since Parallels video card is virtual and relatively high-level (we do not work with hardware directly, but via API or OpenGL instead), it is not possible to effectively split tasks between two video cards, as we are not emulating SLI/Crossfire. In theory, we could map both video cards to the guest OS and somehow allow applications to use it. But there is no practical need for that as there is a tiny amount of peculiar Windows applications that could utilize two cards (because it is much more complicated process than SLI/Crossfire).
Note: The lighting will only display when the device is connected to the Thunderbolt 3 (USB-C) port of your PC. For the internal lighting to be visible, a compatible graphics card must be installed.
Note: The external graphics card must be detected by the system before installing the driver. You may also need to install the latest drivers for the internal graphics card of your PC for the external graphics card to function.
Support is limited to the two most recent major versions of iOS. For example, when a new, major version of iOS is released, the iOS requirement is the new version and the most recent versions that preceded it. The optional Blur my background video effect on iOS requires an operating system of iOS 12 or later, compatible with the following devices: iPhone 7 or later, iPad 2018 (6th generation) or later, and the iPod touch 2019 (7th generation).
Note: REDROCKET-X support requires driver 2.1.31.0 and firmware 1.4.1.16 or higher. Note: NVIDIA Cuda acceleration requires compute capability 2.0 or higher capable GPU on Mac with the latest NVIDIA Cuda Driver. Note: NVIDIA/AMD OpenCL acceleration requires OpenCL 1.1 or higher capable GPU.
Note: REDROCKET support requires driver 2.1.23.0 and firmware 1.1.18.0 or higher. Note: REDROCKET-X support requires driver 2.1.31.0 and firmware 1.4.1.16 or higher. Note: NVIDIA Cuda acceleration requires compute capability 2.0 or higher capable GPU on Mac with the latest NVIDIA Cuda Driver. Note: NVIDIA/AMD OpenCL acceleration requires OpenCL 1.1 or higher capable GPU.
Finding the right graphics card for your Mac can be difficult with limited information available now. Below is a complete (to my knowledge) list of graphics cards available to pre-OSX systems with full driver support.If you see something missing please get in touch so it can be added.
For WebGL in Firefox on Windows, Windows XP or newer is required. The following minimal driver versions are required: either NVIDIA >= 257.21, or ATI/AMD >= 10.6, or Intel driver versions from September 2010 or newer.
In Firefox 6 and newer on X11, the following minimal versions are required: either Mesa >= 7.10.3 (or Mesa >= 8.0 for the Nouveau driver), or NVIDIA >= 257.21, or any version of FGLRX implementing OpenGL 3.0 or newer (but FGLRX is blacklisted when the Linux kernel version is 2.6.32)
In addition to the blacklist, several GPU driver bug workarounds are applied on various platforms. Ideally these bugs will all be fixed. The WebGL conformance test runner disables the browser's driver bug workarounds to expose the underlying issues.
Warning! GPU devices do not in general offer the same level of memory protection as CPU devices. If your code attempts to write outside allocated memory buffers unpredicatable behaviour may result (eg, your video display may freeze, or your system may crash, etc). Do not install OpenCL drivers without first checking for known issues (eg, some computer manufacturers install modified graphics drivers so replacing these may not be a good idea!). If in doubt, seek advice from an IT professional before proceeding further.
Since macOS High Sierra 10.13, the operating system applies a stricter security policy to software that requires kernel extensions (KEXTs). The DisplayLink classic driver installation (version 5.x) includes a system extension (DisplayLinkDriver.kext) that is affected by this policy. The new DisplayLink Manager Graphics Connectivity app (version 1.x) does not use KEXT. This article does not apply if you are using DisplayLink Manager 1.x and macOS Catalina (10.x), Big Sur (11.x) and Monterey (12.x)
Download the latest drivers for your SAPPHIRE Radeon consumer graphics card product and operating system. Also note that most AMD drivers are universal and backwards compatible however they are operating system specific. Always make sure you choose the appropriate operating system for your computer, although the latest drivers should be compatible with most GPUs from previous generations.
