Apple added support for external graphics cards in macOS

Apple has implemented the long-awaited support for the operating system macOS of external video cards that are connected to the Thunderbolt port 3. However, not all Mac computers will use the new feature, as not all video cards are suitable for connection. In addition, in order for everything to work, it is also necessary to support the new function with software.

In June of last year, Apple announced its plans to implement support for external graphics processors in its operating system macOS. And now, almost a year later, official support has become a reality. With the latest update macOS 10.13.4 "High Sierra" users were able to connect a number of different graphics cards to Mac computers. The connection is made via the Thunderbolt 3 port. Such a technical solution allows to increase the productivity of a number of tasks, including games and video editing. In addition, Apple particularly stressed that the new feature, now provided in its operating system for computers, is useful when working with virtual reality. The new message was considered in more detail by Jacob Kastrenakes on the pages of the resource . Of course, not all computer users pay attention to the presence of this new function at all.

The support itself did not surprise itself, because it was planned long ago. But there are a number of limitations regarding what users can do with external graphics processors connected to computers. First of all, users can choose only from those models that are officially supported. At the same time, Apple only supports some of the AMD Radeon graphics cards. This does not mean that GeForce cards will definitely not work. Some users noted that they worked when the new function of the operating system was at the beta stage. The question remains as to whether this compatibility will continue.

In addition, users will not be able to use external video cards in Windows operating system using Boot Camp. However, even the fact that a graphic card is connected to the computer through the Thunderbolt 3 port with the operating system macOS, may not be enough to support the video processor was provided. Developers need to enable support. The new feature will only work on fairly new Mac computers, because the use of an external graphics processor assumes a very high speed provided by Thunderbolt 3. Among the supporting new feature of computers – MacBook 2016 and 2017, iMac 2017 and iMac Pro 2018.

So, if the user has a new computer and uses applications that support the new function, then it will be very useful for those who appreciate the performance of the GPU. The concept of using external video cards is popular in the community of gamers. But the possibility of using additional graphics processors was not available on the Mac, traditionally considered to be computers designed for working with capacious graphics.

Features of the Thunderbolt 3 port play a huge role in the possibility of using the new function, noted on pages Yahoo! . This technology provides a transfer rate of up to 40 gigabits per second. This speed is sufficient to ensure that between the Mac and the external video processor there is a fast exchange of data necessary for processing textures and rendering data in the game process, and this additional work done by the hardware did not cause any noticeable problems to the user in games, 3D rendering applications , virtual reality content and other applications that require an additional graphics card.

This is probably the reason why during the Best Buy sale, the price of the MacBook Air was significantly reduced. The port speed of Thunderbolt 2 is not sufficient to transfer data generated by an external graphics card. Its speed reaches "only" 20 gigabits per second. Thus, it is four times faster than the usual USB 3.1 Gen 1 port, but this is not enough for an external graphics processor. The speed of data transfer is often the determining factor that makes possible the use of a new technology.

Thus, for several hundred US dollars, a user can make his computer much more productive. The new feature can be especially useful for those who use the MacBook Pro.
