Latest macOS
macOS Tahoe 26›macOS 27 Golden Gate
What does this mean?
macOS is the software that runs the Mac: the desktop, Finder, the built-in apps, the settings and the security protection. Apple releases a new version every autumn.
A Mac on the newest macOS gets new features and regular security fixes. A Mac stuck on an older version keeps working, but over time apps start requiring a newer macOS, and security fixes stop. Apple has said macOS Tahoe 26 is the last version for Macs with Intel processors.
Matters most if: You use work, school or banking apps that need a recent macOS.
Apple Intelligence
GainWhat does this mean?
Apple Intelligence is Apple's set of AI features: writing help that rewrites or proofreads your text, summaries of long emails and notifications, Clean Up in Photos, and the new Siri AI.
On Mac it needs Apple silicon, the M1 chip or later. Macs with Intel processors cannot get it. Which features you see also depends on your country and language.
Apple repair support
Repaired by Apple (same on both)
What does this mean?
Apple counts from when it stopped selling the model, not from its release date. Vintage: Apple stopped selling it 5 to 7 years ago; repairs only while parts last. Obsolete: over 7 years ago; Apple no longer repairs it.
Checked against Apple's vintage and obsolete products list on 2026-10-11. Mac laptops may still get battery-only repairs for up to 10 years after Apple stopped selling them, if parts are available.

- M2 Ultra 24-core CPU / 76-core GPU
Chip
3.5GHz 8-core Intel Xeon W›Apple M2 Ultra
What does this mean?
Ultra is the largest Apple silicon chip in a generation, with up to twice the CPU and GPU cores of the Max chip from the same generation. For M1, M2 and M3 Ultra, Apple says it connects two Max chips with a link it calls UltraFusion.
Apple uses Ultra chips only in Mac Studio and Mac Pro. The extra cores help most with work that can use all of them at once, such as video exports, 3D rendering and machine learning.
Matters most if: You edit high-resolution video or work with very large 3D or machine learning projects.
CPU cores
8›24
What does this mean?
The CPU is the part of the chip that runs your apps. More cores means it can work on more things at the same time.
More cores help most when exporting video, compiling code or running many apps at once. For browsing and email, the difference is small. Cores are only comparable within the same family: one Apple silicon core and one Intel core do not do the same amount of work.
GPU cores
Not published by Apple›60
What does this mean?
The GPU handles graphics: what you see on screen, games, and video and photo effects. Apple lists GPU cores for its own chips.
More GPU cores make games, 3D work and video editing smoother. "Not published by Apple" means the Mac uses Intel or AMD graphics, which Apple does not describe in cores.
Neural Engine cores
None (Intel)›32
What does this mean?
The Neural Engine is a part of Apple silicon built for machine learning tasks, such as recognizing faces and text in photos.
It speeds up features like Live Text, photo search, voice dictation and Apple Intelligence, while using little battery. Intel Macs do not have one.
Memory type
DDR4 ECC›Unified memory
What does this mean?
Memory (RAM) is the working space for open apps and files. Apple silicon uses unified memory: one pool shared by the CPU, GPU and Neural Engine. Intel Macs list a memory type such as DDR4.
Unified memory is part of the chip, so it cannot be added later. Apple's spec pages list user-accessible memory slots only for the 27-inch Intel iMac and the 2019 Mac Pro.
Memory (base)
32 GB›64 GB
What does this mean?
How much memory (RAM) the cheapest configuration comes with, in gigabytes (GB).
More memory lets you keep more apps and browser tabs open without slowing down. 8 GB is enough for browsing and documents; 16 GB or more helps with photo editing, video and many apps at once. On Apple silicon Macs memory cannot be added later.
Matters most if: You keep many apps or tabs open, or edit photos and video.
Memory (most you can order)
1.5 TB›192 GB
What does this mean?
The most memory you could order from Apple for this model.
Only matters if you plan to buy a high-end configuration, for example for large video projects or software development.
Storage (base)
256 GB›1 TB
What does this mean?
Storage is where your files, photos and apps are kept. This is the amount in the cheapest configuration. 1 TB (terabyte) is 1,024 GB. Some older iMacs came with a hard drive or Fusion Drive instead of an SSD; the notes say when.
A desktop Mac can keep an external drive plugged in all the time, which makes a smaller internal drive easier to live with. Photo libraries and video fill storage fastest.
Storage (most you can order)
8 TB (same on both)
What does this mean?
The most storage you could order from Apple for this model.
Only matters if you need to keep very large files on the Mac itself rather than on an external drive.
Keyboard & input1 change
Unlock
None (password only)›Touch ID on the included keyboard
What does this mean?
Touch ID reads your fingerprint from a key on the keyboard. Without it, you type your password.
With Touch ID you unlock the Mac, approve Apple Pay and fill in passwords with one touch instead of typing.
Ports & charging4 gains · 2 changes · 1 unconfirmed
USB-C ports
4x Thunderbolt 3 (USB-C)›8x Thunderbolt 4 (USB-C)
What does this mean?
The sockets on the Mac, front and back together. Each row shows one port gained or lost. Ethernet has its own row.
Built-in HDMI and an SD card slot mean fewer adapters when you connect a TV or projector or copy photos from a camera. With fewer ports you rely more on USB-C hubs and adapters.
Matters most if: You connect displays, cameras or many accessories.
2x HDMI
GainFront: USB-C ports
2x Thunderbolt 3 (USB-C)›2x Thunderbolt 4 (USB-C)
What does this mean?
The ports on the front of the Mac, which you can reach without turning it around. They are also counted in Ports.
Handy for things you plug in and out often, such as headphones, a USB stick or an SD card from a camera. "Not listed separately by Apple" means Apple's spec page lists the ports without saying which are on the front.
Thunderbolt version
Thunderbolt 3›Thunderbolt 4
What does this mean?
Thunderbolt is a fast connection that uses the USB-C plug (Thunderbolt 2 used an older, smaller plug). Gb/s is gigabits per second. Thunderbolt 2 goes up to 20 Gb/s, Thunderbolt 3 and 4 up to 40 Gb/s, and Thunderbolt 5 up to 120 Gb/s.
Faster Thunderbolt matters for external SSDs, docks and high-resolution displays. For charging, keyboards and mice, every version works the same.
External displays (most)
Not published by Apple›8 external displays
What does this mean?
The most separate displays you can connect at the same time, as Apple's spec page lists it. On an iMac this is on top of its own screen.
Very high resolutions or refresh rates can lower the number; Apple's spec page lists the exact combinations. More display support helps when you spread your work across several screens.
Matters most if: You want two or more monitors on your desk.
Wi-Fi
Wi-Fi 5›Wi-Fi 6E
What does this mean?
Wi-Fi generations. Each new one handles more devices at once and higher speeds: Wi-Fi 5 (2014), Wi-Fi 6 (2019), Wi-Fi 6E adds a new, less crowded radio band, Wi-Fi 7 is the newest.
You only get the extra speed if your router supports the same generation. With an older router, the difference is small.
Bluetooth
Bluetooth 5.0›Bluetooth 5.3
What does this mean?
Bluetooth connects wireless headphones, mice, keyboards and game controllers. Newer versions have more range and use less power.
Most accessories work with any of these versions. Newer versions mainly help with range and connection stability.
Ports on both
2x USB-A (up to 5Gb/s), 3.5 mm headphone jack (same on both)
Ethernet
10Gb Ethernet (same on both)
What does this mean?
Ethernet is a wired network connection: a cable from the Mac to your router. Gigabit Ethernet carries up to 1 Gb/s (gigabit per second), 2.5Gb Ethernet up to 2.5 Gb/s and 10Gb Ethernet up to 10 Gb/s. "10Gb option" means Apple sold a 10Gb port as an option when you ordered; "optional" means Ethernet itself was an option.
A cable is steadier than Wi-Fi for video calls and large downloads. The faster speeds only help if your router, switch or network drive is just as fast.
Matters most if: You copy large files to and from a network drive or other computers.
Maximum continuous power
1280 W (same on both)

Weight
17.6 kg›Not confirmed
What does this mean?
Weight in kilograms. 1 kg is about 2.2 pounds.
For a desktop Mac, weight matters when you move it or take it between places.

Speakers
Built-in speaker (same on both)
What does this mean?
How Apple describes the Mac's speakers on its spec page. Apple's wording varies between models. We show it exactly as Apple lists it.
Apple lists a single built-in speaker for Mac mini, Mac Studio and Mac Pro, so for music and films you will want speakers or headphones. Systems with force-cancelling woofers give fuller sound with more bass.
