Apple on Thursday pushed out a fourth beta of macOS 10.13.2 for developers, available through the company's developer portal or as a Mac App Store update.
The code comes just three days after the third beta. In its finished form 10.13.2 is largely expected to be a maintenance release, the main exception being support for introductory pricing with auto-renewable subscriptions.
The same support should be coming to iOS 11.2 and tvOS 11.2. Previously, developers were only able to offer free trial periods or a full-price subscription.
It's still unclear when the finished version of macOS 10.13.2 will be ready, but it will likely go live on or around the same time as iOS 11.2, tvOS 11.2, and watchOS 4.2.
