New MacBook Pro Models Tipped to Launch With macOS 26.3; M5 Pro and M5 Max Chips Might Not Arrive Before March

Highlights

• Apple is expected to launch new MacBook Pro models with M5 Pro and M5 Max chips during the macOS 26.3 release cycle.
• M5 Pro and M5 Max chips availability may be delayed until March.
• Production challenges at TSMC and Apple’s advanced SoIC packaging technology may be causing delays.

Apple is reportedly preparing to introduce updated MacBook Pro models powered by the M5 Pro and M5 Max chips with the launch expected to align with the macOS 26.3 release cycle. According to Bloomberg’s Mark Gurman, the faster MacBook Pro variants are tied to Apple’s upcoming software update.

“Apple’s faster MacBook Pros are planned for the macOS 26.3 release cycle,” Gurman wrote in his Power On newsletter. He further added, “I’m told the new models — code-named J714 and J716 — are slated for the macOS 26.3 software cycle, which runs from February through March.”

macOS 26.3 Beta Timeline

While macOS 26.3 is currently in beta testing, a public rollout is widely expected in February. Gurman did mention March as a possibility. However, that scenario would likely depend on delays in the beta cycle or if Apple chooses to pair the hardware launch with macOS 26.3.1 or a later update.

As things stand, the macOS 26.3 Release Candidate is anticipated in the first half of February, suggesting that a MacBook Pro announcement could happen soon.

This timeline aligns with earlier reporting from October, when AppleInsider’s Marko Zivkovic stated that MacBook Pro models featuring the M5 Pro and M5 Max chips.

“After the M5 MacBook Air, we’ll see the arrival of Apple’s high-end M5 Pro and M5 Max MacBook Pro configurations. They will be available in 14-inch and 16-inch sizes, much like the current M4-based line. All variants of the J714 and J716 MacBook Pros are expected to ship with macOS 26.3,” Zivkovic explained.

With multiple sources now echoing similar claims, the launch window appears increasingly credible.

No Major Design Changes Expected for M5 MacBook Pros

Aside from the chip upgrades, no major hardware changes are expected for these MacBook Pro models. Looking further ahead, Apple is said to be planning a significant redesign in late 2026 or 2027.

Rumoured upgrades include an OLED display with touch support, new M6 Pro and M6 Max chips, a slimmer chassis, and built-in cellular connectivity.

M5 Pro and M5 Max Chip Launch Delayed Until March

Meanwhile, a separate report suggests that Apple’s M5 Pro and M5 Max chips themselves may not debut before March. The delay is notable, as the previous M4 Pro and M4 Max chips launched in November 2024, placing Apple well outside its usual release window.

Weibo tipster Fixed-focus digital claims the new chips could be unveiled about a month from now, though no clear reason for the delay has been provided.

Supply-side challenges could be a contributing factor. Apple’s manufacturing partner TSMC is reportedly facing constraints that may have slowed chip production. There are also indications that Apple’s advanced SoIC (System-on-a-Chip) packaging technology may have encountered manufacturing hurdles.

SoIC Packaging Could Improve Costs and Thermal Performance

According to the same leak, the M5 Pro and M5 Max chips could end up being slightly cheaper to produce, although the reduction is expected to be modest. Even so, any cost savings would be meaningful amid ongoing DRAM supply pressures across the industry.

SoIC packaging could also help Apple manage thermal performance more effectively. Previous reports have suggested that the standard M5 chip can reach temperatures of up to 99 degrees Celsius under sustained workloads. Improved packaging in the Pro and Max variants may help address these heat-related concerns.

Additionally, SoIC may enable Apple to separate CPU and GPU blocks on the chip die, potentially allowing for more flexible configurations tailored to different performance needs rather than a single, uniform design.

As always, these details should be taken with caution, as Apple is known to revise its plans without notice.

FAQs

Q1. When will the new MacBook Pro models with M5 Pro and M5 Max chips launch?

Answer. They are expected to arrive during the macOS 26.3 release cycle, likely between February and March 2026, though the chips themselves may not debut until March.

Q2. Will the upcoming MacBook Pros feature any major design changes?

Answer. No, aside from the chip upgrades, no major hardware changes are expected. A significant redesign with OLED displays, touch support, slimmer chassis, and cellular connectivity is planned for 2026–2027.

Q3. Why might the launch of M5 Pro and M5 Max chips be delayed?

Answer. Reports suggest supply-side challenges at TSMC and hurdles with Apple’s advanced SoIC packaging technology may have slowed production, though the new packaging could improve costs and thermal performance.
