Upgrade Soon: Intel-based Macs and Apps Are On Their Way Out

ByEmily Dolloff

In 2020, Apple introduced the M1 chip, the first of the family of Apple silicon chips that now power the entire Mac lineup. At the time, Apple said it would “continue to support and release new versions of macOS for Intel-based Macs for years to come.”

Since then, it has become clear that Macs with Apple silicon are notably better than Intel-based Macs in nearly every way, and we’re now up to the impressive M4 chip family. Nonetheless, some people continue to hold onto their Intel-based Macs. Now we know precisely when those Macs will ride off into the sunset. Intel-based Macs had a good run, but it’s time to move on to Macs with Apple silicon.

macOS Support for Intel-based Macs

During WWDC 2025, Apple announced that macOS 26 Tahoe will be the last version of macOS to support Intel-based Macs, specifically these four models:

  • 16-inch MacBook Pro from 2019
  • 13-inch MacBook Pro with four Thunderbolt ports from 2020
  • 27-inch iMac from 2020
  • Mac Pro from 2019

macOS 27, expected in 2026, will run only on Macs with Apple silicon. However, the Intel-based Macs listed above will continue to receive security updates for macOS 26 for another two years. That means that all Intel-based Macs will have lost security viability by 2028.

How can you determine the type of Mac you have if you’re unsure? Choose About This Mac from the Apple menu and look at the Processor or Chip line.

Rosetta 2 Support for Intel-based Apps

There’s another aspect to Apple’s waning support for Intel-based Macs: Rosetta 2. The Rosetta translation environment allows apps written for Intel-based Macs to run on Macs with Apple silicon. The process is almost transparent because macOS downloads Rosetta the first time it needs it, and after that, Intel-based apps just work. They may be slower than native Apple silicon apps, but Apple’s M-series chips are so fast that the translated apps often run faster than on Intel-based Macs.

During WWDC, Apple published documentation clarifying the future of Rosetta. Apple plans to keep Rosetta available in its current state in macOS 26 and next year’s macOS 27. After that, however, Apple says it “will keep a subset of Rosetta functionality aimed at supporting older unmaintained gaming titles that rely on Intel-based frameworks.”

Given that Apple silicon has been the future since 2020, nearly all developers have updated their apps to run natively on the M-series chips. Very few actively maintained apps still require updates; Rosetta is primarily useful for those who rely on obsolete apps or older versions of current apps.

How can you find out whether an app you rely on is Intel-based? Open System Information (it’s in your Applications folder, nested in the Utilities folder), click Applications in the sidebar, click the Kind column header, and then scroll to find all the apps listed as Intel. To find out where one of these apps is stored on your Mac, select its listing and look at the Location field at the bottom of the window.

What All This Means

There’s a difference between what’s possible and what’s recommended.

Apple’s announcements draw a line in the sand at 2028 for when it will be too dangerous to continue using the last batch of supported Intel-based Macs. Older Intel-based Macs will cease to receive security updates even sooner—two years after they are no longer supported by macOS. If budget or compatibility with obsolete software or hardware prevents you from upgrading to a Mac with Apple silicon, it is possible to limp along with an Intel-based Mac for a bit longer.

Similarly, Rosetta will make it possible for you to continue using an obsolete Intel-based app on a Mac with Apple silicon through macOS 27, which will cease to receive security updates in 2029. Old games may continue to work for longer.

If we don’t sound enthusiastic about those possibilities, we’re not. Even the very first M1-based Macs outperform Intel-based Macs, and the performance difference is far wider with today’s M4, M4 Pro, and M4 Max chips. You aren’t doing yourself any favors by hanging onto an Intel-based Mac if you can afford to buy a new one.

Because so much time has passed, it’s likely that any Intel-based app that has not already been updated to run on Apple silicon will never be updated, so we recommend that you start looking for a replacement.

With both hardware and software, the longer you wait, the more problems you’re likely to encounter when upgrading. In part, that’s because both professional and community expertise fades with time—people who solved the problems you’ll encounter did so years before and may no longer remember the details. We also often see small conversion utilities built to help with transitions, but those tend to disappear or stop working after most people have moved on.

Most businesses upgrade their Macs every three to five years because the frequency of problems in that time frame increases to the point where employee downtime and maintenance and consulting costs outweigh the cost of upgrading. That financial equation is less evident to individuals, but it applies similarly.

So if you’re still using an Intel-based Mac or app, you now have a firm end date. But seriously, don’t wait that long.

    You know I am a rabid Boston Celtics fan, and I have been since I was a child listening to games on my transistor radio, searching for the gravely voice of Johnny Most. These days our All-Star and team leader is Isiah Thomas who NBA hall of famer, Tommy Heinsohn, always refers to as the “little guy”. We have been thinking of changing our dog, Max’s name to the little guy as a result.

    It was little iPhone and little iPad Pro day at the Apple event. Apple introduced the 4-inch iPhone SE and the iPad Pro 9.7-inch tablet. In other hardware announcements, there were new watch bands for the Apple Watch and a new Lightning to USB 3 camera adapter. The original iPad Air is now discontinued and the iPad Air 2 with a more limited selection becomes the entry-level 9.7-inch iPad.

    I have gotten used to the size of my iPhone 6 but there are many people that want a smaller iPhone. Having a big iPhone 6 or 6+ sticking out of your back pocket is an invitation to theft and they do get a big bulky in the front pocket of your jeans. The iPhone SE uses the iPhone 5 form factor, with a 4-inch screen and aluminum case. The iPhone SE is not crimping on power though, as it meets almost all of the specifications of the iPhone 6s. It fails to match up to the current iPhone lineup only in the lack of the 3D Touch technology, the Taptic Engine that provides feedback you can feel, and slower wireless networking. It’s either $399 or $499, with 16 GB or 64 GB of storage, and comes in the same four colors, Silver, Space Gray, Gold and Rose Gold. We have found that most cases for the iPhone 5 should work with the iPhone SE. These are shipping on March 31.

    The 12.9-inch iPad Pro, introduced last year with the Apple Pencil and Smart Keyboard, has enjoyed some moderate acceptance as a productivity device. I can see how for some, it might be their only device. And for artists, architects and others the iPad Pro is a digital drawing board like no other. But it is 12.9 inches and that is just a bit large for some. Apple introduced the 9.7-inch iPad Pro to meet this need, which meets or exceeds many of the larger model’s specs.

    For instance, the smaller model’s screen can display more colors and adjusts its white balance to match the ambient light in the room. Its cameras are notably better — the rear camera is 12 megapixels instead of 8 and has a True Tone flash, while the front camera is 5 megapixels instead of 1.2 and can use the screen as a flash. Plus, the new iPad Pro can record 4K video instead of just 1080p. I assume we will see these upgrades to the 12.9 inch iPad Pro in the future but the smaller version is a powerhouse.

    The 9.7-inch iPad Pro’s A9X chip is somewhat slower, it has half the RAM, and its Lightning port transfers data at only USB 2 speeds. But if the size is right for you, prices start at $599 for 32 GB of storage and go up to $899 for 256 GB. It will be shipping on March 31 in four colors: silver, gold, space gray, and rose gold. Cases and accessories designed to fit the iPad Air 2 should work with the 9.7-inch iPad Pro. We have our orders in with Apple and should have stock by the launch date. I think this new iPad Pro is going to be the iPad of choice for a lot of people.

    Apple also introduced the $39 Lightning to USB3 camera adapter. It is much more than a camera adapter though and opens the Lightning port to a lot of USB devices. With the Lightning to USB 3 Camera Adapter, it’s easy to transfer photos and videos from your high-resolution digital camera to your iPad Pro.
    If you connect with a USB Power Adapter, you can connect USB peripherals like hubs, ethernet adapters, audio/MIDI interfaces, and card readers for CompactFlash, SD, microSD, and more. This is a new and important step by Apple in making the Lightning port much more versatile.
