Apple just released the third developer beta for macOS Tahoe 26.5 today. This fresh update gives app builders a chance to test out changes on Mac computers before the software hits the public. According to official developer release notes, the tech company is currently keeping things simple and focusing on background fixes.
This launch happens right as Apple pushes out similar test software for other devices. The company is releasing the third beta of iOS 26.5 to iPhone developers and simultaneously seeding iPadOS 26.5 beta 3 with a focus on stability.
Developers can download the new computer update from the system settings
Right now, this third beta heavily focuses on fixing bugs and smoothing out background performance. Apple is mainly clearing out errors found in earlier test versions. It wants to make sure the operating system runs well without sudden crashes before shipping it to regular users.
Anyone holding a registered developer account can download the update directly to a Mac. You simply open the System Settings app, click on General, and navigate to the Software Update section. The beta option will pop up right there on the screen.
It is always a smart idea to keep test software off your main computer. Beta updates often drain batteries quickly or cause important daily apps to freeze. A public version for regular testers should arrive in the coming days.
