Developer testing of High Sierra beta 9 ongoing.
Apple has released an update to macOS High Sierra for developer testing, which is the second beta for a week. Beta 9 brings improvements to the File System, Photos, Safari, and more.
Registered developers can try out this version on their machines, enjoying all latest improvements and fixes before the regular public testers and everyone outside of the testing program.
macOS High Sierra introduces many new features like native eGPU support, Safari improvements, new features for Photos, Mail, and the new APFS file system that already appeared in iOS 10.3.
Apple will officially roll out the update to the public later this fall, but we expect all details to emerge at the September 12 event in California.
