Three Upcoming Apple Products Seen in macOS 26.3 Code

macOS 26.3 plans for Apple’s rumored cheaper MacBook, as well as two Studio Display models, according to Apple. MacworldFilipe Espósito.

Espósito found the following codenames within the macOS 26.3 source code, and revealed upcoming products that may be compatible with them, based on a previous report from BloombergMark Gurman and others.

Code names:

• J700: A low-cost MacBook
• J427: New Studio Display
• J527: The new, state-of-the-art Studio Display

This is far from the first time these codenames have been seen in Apple software updates. In accordance with MacRumors contributor Aaron Perris, the codenames were also present in updates such as macOS 26.2 and iOS 18.5 last year.

With more hints piling up, it’s clear that all three products are nearing release.

The prevailing thought is that Apple will launch a low-cost MacBook as part of three days of new product announcements in the first week of March. The media would then get to work with the laptop during the “Apple Experience” in New York, London, and Shanghai on Wednesday, March 4 at 9 am Eastern Time.

The new Studio Displays are expected to be released in the first half of 2026, but it is not clear if they will be part of the announcements in the first week of March.

The cheaper MacBook is rumored to be powered by a version of the iPhone 16 Pro’s A18 Pro chip, rather than an M-series chip. The laptop will be available in a variety of bright colors, such as yellow, green, blue, and/or pink. Other rumored specs include a 12.9-inch display and 8GB of RAM. Initial pricing remains to be seen, with estimates ranging from $599 to $799 in the United States.

The low-cost MacBook will be the new model positioned below the MacBook Air, and will mark a refresh of the “MacBook” brand (without the “Air” or “Pro” name). Apple sold the Intel-based 12-inch “MacBook” from 2015 to 2019.

At least one of the Studio Display models is rumored to feature a 27-inch screen with a mini-LED backlight, up to a 90Hz or 120Hz refresh rate, HDR support, and an A19 chip or A19 Pro chip. No major design changes are expected.

If the next Studio Display gets a mini-LED backlight and HDR support, its maximum brightness and contrast ratio will be higher than the current model. And the new A19 or A19 Pro chip – from the current A13 Bionic – should contribute to performance improvements, camera-related improvements, and more.

There are no details about the second Studio display. Most likely, it would be a top model, and we can only dream of a larger screen size of 32 inches.

The current Studio Display launched in March 2022, alongside the original Mac Studio. It has a 27-inch mini-LED backlight screen, 5K resolution, 60Hz refresh rate, up to 600 nits brightness, built-in camera and speakers, one Thunderbolt 3 port, and three USB-C ports. In the US, pricing starts at $1,599.
