Apple in 2017 announced that would add support for external GPUs to macOS. And now the company has finally rolled out the support with the latest update to macOS High Sierra. Now users will be able to connect different graphics card to the Mac using a Thunderbolt 3 port and make use of the additional power to speed up high-end processes such as gaming and video editing. The company specifically highlights its use for virtual reality.
Although, external GPU isn't something new, for Apple's walled garden this might be welcomed change. However, there are few restrictions on what you can do with the external GPUs. First being, only a few models are officially supported. Also, the company is only supporting some of AMD's Radeon GPUs.
Users will also not be able to use external GPUs on Windows through Boot Camp. Finally, to get the external GPU support, you will need a new enough Mac, since the support relies on Thunderbolt 3. So users with 2016 and 2017 MacBook Pros, 2017 iMacs, and the iMac Pro will be the only ones to take advantage of the new service. So if have a new machine and apps to support it, then this might interest you.
Apple also rolled out the iOS 11.3 update for the iPhone, iPad and iPod Touch. The update brings an array of new features including the ability to turn off the processor throttling for iPhones with aging battery life. The update also adds new Animojis for the iPhone X, enhanced ARKit for better-augmented reality and more.
The 'Battery Health' The feature is the result of the bad press that Apple witnessed after it was discovered that the system automatically slows down the processor's performance to avoid unexpected shutdowns. Apple also issued a public apology and offered cheaper battery replacements programs. But turning down the throttling also result in lower battery life.
There are chances that the battery won't be able to provide enough power for some intense tasks. The best alternative to maintain the peak performance and avoid throttling is to get the old battery replaced. The new feature only applies to the iPhone 7 / 7 Plus, SE, 6S / 6S Plus, 6 / 6 Plus as of now. Users will also see a new battery health option that will notify if the battery needs servicing.
