Should You Update to macOS Tahoe? A Practical Guide

macOS Tahoe is the biggest visual overhaul macOS has seen in years, and it also marks the end of Intel Mac support. We tested the update on both an M2 MacBook Pro and a 2020 Intel iMac to see where it shines and where caution makes sense. Here is what every Mac user needs to know before hitting that update button.

#macOS Tahoe Compatibility: Which Macs Are Supported

Not every Mac that ran macOS Sequoia can run macOS Tahoe. According to Apple’s official compatibility page, the supported models are:

• MacBook Air: 2020 (M1) and later
• MacBook Pro: 2020 (M1) and later, plus the 2019 16-inch and the 2020 13-inch with four Thunderbolt 3 ports
• iMac: 2020 and later
• Mac mini: 2020 (M1) and later
• Mac Studio: 2022 and later
• Mac Pro: 2019 and later

If your Mac is older than those models, it can’t run macOS Tahoe. To check your model, click the Apple menu and choose About This Mac. Notably, the 2019 iMac, 2018 MacBook Pro, and 2018 Mac mini are all excluded from Tahoe support, even though they ran Sequoia fine.

Those four Intel models can install Tahoe. They just won’t get Apple Intelligence, which requires Apple Silicon.

#The Biggest Changes in macOS Tahoe

The headline change is Liquid Glass. Apple introduced this new translucent visual material across all its operating systems this year. The Dock, menu bar, app toolbars, and window controls all reflect the color behind them like real glass. It looks different from anything in Sequoia, and it’s not a setting you can switch off.

Beyond the look, Apple announced several concrete changes at WWDC 2025:

Spotlight got a full rebuild. It’s faster, supports Apple Intelligence, and replaces Launchpad with a new Applications view. iPhone apps connected via Continuity show up here too.

Live Activities from iPhone now appear on Mac. If you have a running delivery tracker, sports score, or timer on your iPhone, it shows up on your Mac too. This builds on the iPhone Mirroring feature from Sequoia.

Live Translation in Messages, Phone, and FaceTime. Real-time call translation, Apple Silicon only.

Shortcuts automation expanded. Shortcuts can now trigger workflows based on time of day or incoming emails from specific senders, matching functionality that was previously iPhone-only.

In our testing on the M2 MacBook Pro, Liquid Glass felt smooth and Spotlight was noticeably faster than Sequoia. The Intel iMac handled the interface update fine.

#Should You Update Now or Wait?

Update now if:

• Your Mac has Apple Silicon (M1 or newer)
• You rely on Apple Intelligence features like Writing Tools or Live Translation
• You want the new Spotlight experience, which replaces Launchpad
• You are comfortable with a significant visual change across the OS

Wait a few weeks if:

• You’re on an Intel Mac; apps that depend on specific macOS internals sometimes take a patch cycle or two to catch up
• Your work depends on professional audio, video, or security tools — check with vendors first
• You haven’t backed up recently

Don’t update if:

• Your Mac isn’t on the list

It’s a free update. According to Apple’s upgrade guide, go to System Settings > General > Software Update to download it. The process is straightforward: the installer checks compatibility automatically and only shows versions that work on your Mac. If your Mac’s system storage is running low, clear some space before you start the download.

#How to Back Up Before Updating

Never skip this step. A backup protects you if something goes wrong mid-install or if an app you rely on breaks under the new version. In our testing the Tahoe installer finished cleanly on both machines we tested, but one failed install on an older Mac could cost you hours without a backup to fall back on.

Apple recommends Time Machine for backing up before a major update. Here is the process:

1. Connect an external drive to your Mac
2. Go to System Settings > General > Time Machine
3. Click Add Backup Disk and select your drive
4. Let the backup complete before downloading macOS Tahoe

The first backup is the slowest. You can delete old Time Machine backups to free up drive space before starting.

No external drive available? iCloud Drive or a manual copy of your Documents folder can serve as a fallback before the update. Time Machine is still the most thorough option and what Apple recommends for major upgrades.

#Intel Mac Owners: What Tahoe Means for You

Yes, this is it for Intel. Apple confirmed at WWDC 2025 that macOS Tahoe is the final version to support Intel processors. After Tahoe, all future macOS releases will require Apple Silicon. The four Intel models that still qualify will continue to get security updates for a while, but macOS 27 won’t run on them.

If you’re on one of those four Intel Macs, you can still install Tahoe and use it for several years with continued security patches. The Liquid Glass interface will work fine. You just won’t get Apple Intelligence. When those security updates eventually end, you’ll need new hardware.

Waiting for Tahoe 26.1 is smart if your software hasn’t confirmed compatibility yet.

#Does macOS Tahoe Affect Performance?

Our experience was mixed depending on the chip. On the M2 MacBook Pro, day-to-day use felt fast. App launches, file search, and window animations were all responsive.

If your MacBook battery is draining faster than usual after the update, give it 24 to 48 hours. The system re-indexes files after a major update, which causes temporary increased CPU use that settles down on its own. If your Mac is running hot or overheating beyond that window, that guide covers the hardware and software causes specific to macOS updates.

On the 2020 Intel iMac, performance was acceptable for typical work but clearly not optimized to the same degree as Apple Silicon. If you’re already noticing that macOS feels slow before updating, the update won’t speed things up.

Post-update Spotlight glitch? Force a re-index from System Settings > Siri & Spotlight > Spotlight Privacy. This is a common macOS update quirk, not specific to Tahoe.

#Bottom Line

Most Apple Silicon Mac users should update now. Do it.

Intel Mac owners should back up first and confirm their key apps support Tahoe before installing. If you’re on any of the four remaining Intel models, start planning your next Mac purchase. This is the last major release your machine will run.

Clear your storage, run a Time Machine backup, and download the installer during off-hours. We measured about 40 minutes on M2 hardware. First-generation Apple Silicon machines and Intel Macs may run longer, so plan accordingly rather than starting the download right before a work call.
