Checking a Mac's compatibility means looking at its processor, its macOS version and the applications it runs. Keep the hardware question separate from the software question: a computer's place on a macOS compatibility list does not tell you the processor requirements of every application installed on it. Apple's transition guidance gives users a way to work through those questions, from the Mac model to the Kind field in an application's information window.
Make a short note for each application you depend on: its name, the Kind label, and the macOS release under consideration. These are useful questions to take to a compatibility discussion because each describes a specific part of the setup. A notebook model, an operating system version and an application type are related pieces of information, but none is a substitute for the others.
The 2020 Announcement and Rosetta
In 2020, Apple announced the transition from Mac computers with Intel processors to Macs with Apple silicon. Its guide to Intel-based applications explains Rosetta, the software created to ease that change. Rosetta automatically translates Intel-based apps for use on Apple silicon, working in the background. Apple says it is available on any Apple silicon Mac using macOS 27 or earlier.
For users, that explains why an Intel-based application can run on an Apple silicon computer. It also gives a reason to check applications individually: running through translation and being made for Apple silicon are different ways of reaching the same familiar app window. Apple describes Rosetta as giving developers and users more time to adapt their applications to Apple silicon.
Which Macs Run the Current macOS
Apple's macOS 27 Golden Gate compatibility list names MacBook Neo (2026); MacBook Air, MacBook Pro and Mac mini with Apple silicon (2020 and later); iMac with Apple silicon (2021 and later); Mac Studio (2022 and later); and Mac Pro with Apple silicon (2023). Read the model name, year and processor wording together. A year alone does not establish a match where Apple specifies Apple silicon.
The macOS Tahoe 26 list also includes MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), iMac (Retina 5K, 27-inch, 2020) and Mac Pro (2019). Those entries do not appear on the macOS 27 list. Compatibility is specific to the operating system version: appearing on the Tahoe list is not enough to establish compatibility with Golden Gate.
Take care with similarly dated model entries. The Tahoe list distinguishes the 13-inch MacBook Pro with M1 from the 13-inch 2020 model with four Thunderbolt 3 ports. When comparing lists, carry over the complete wording rather than shortening both to "2020 MacBook Pro." The precise model description is what makes the comparison useful.
Apple's September 14, 2026, release announcement says macOS 27 began rolling out that day. Use the release number alongside the name when comparing requirements, so the hardware list and the application guidance refer to the same version.
How to Tell Whether an App Is Intel-Only
Apple describes a Finder check that works one application at a time. Most applications are in the Applications folder, available from a Finder window's sidebar. Select an application once, then choose File > Get Info or press Command-I. In the information window, find Kind and read the label:
- Application (Intel) means the app is made for a Mac with an Intel processor.
- Application (Universal) means the app is made for both Apple silicon and Intel processors.
- Application (Apple silicon) means the app is made for a Mac with Apple silicon.
On macOS 27 Golden Gate or later, another route is System Settings > General > About. In the macOS section, click Details next to Intel-based Apps. Apple describes this as a list of apps recently used or installed in common locations. Keep that description in mind when checking a particular application; the Finder method lets you inspect the app itself.
What Changes with macOS 28
Apple warns that opening an Intel-based app may produce a notice that support is ending and that the app, or a component it uses, will not work with macOS 28. That warning makes application checks relevant even when a program opens successfully today. The Rosetta guidance covers macOS 27 and earlier; a successful launch under one release should not be treated as an assurance about the next. Note the application named in any notice and review its requirements before planning a move to macOS 28.
Updating Apps and Plug-ins
Apple recommends updating Intel-based applications for Apple silicon. Its warning refers to both an application and a component used by it. When reviewing an application or a plug-in, keep the question specific: what software does the notice identify, and what does its information say about compatibility? Record the app's Kind label alongside any notice rather than assuming the label answers every question about a component. That gives a clearer starting point for deciding which application needs attention.
Use the Finder result to sort the next question. If Kind says Intel, Apple's advice to update for Apple silicon applies to that app. A Universal label describes an application made for both processor families. Save that wording as written, especially when asking someone else to help interpret a compatibility notice. This avoids reducing every application to a vague description such as "an older app."
A Mac Built on an A-Series Chip
Apple introduced MacBook Neo on March 4, 2026, describing a 13-inch notebook with an aluminum enclosure and an A18 Pro chip. Apple identifies it as an Apple silicon Mac. For compatibility checks, the useful connection is between that hardware description and the MacBook Neo entry on the macOS 27 list. The processor name describes the computer; the Finder labels describe its applications. Keeping both in view turns a broad processor transition into checks a user can make for the machine and software at hand.
