Apple has released the release candidate (RC) for macOS 26.4, just a week after beta 4.
If no major issues are found, this build will become the public version rolling out to all users soon.
But unlike a typical minor update, macOS 26.4 quietly addresses a few real usability problems Mac users have been dealing with for months.
macOS finally fixes the annoying window resize cursor bug
If you’ve used recent versions of macOS, you’ve probably noticed this: the window resize cursor doesn’t align properly with the window corner.
It’s a small issue, but one that makes resizing windows feel inconsistent and slightly broken. With macOS 26.4, Apple finally fixes this bug.
It’s not a headline feature, but it’s the kind of quality-of-life fix that improves daily workflow instantly.
A native battery charge limit (something Mac users have wanted for years)
macOS 26.4 introduces a Charge Limit setting, allowing users to cap charging between 80% and 100%.
This directly targets a long-standing problem:
Keeping your Mac plugged in all day can degrade battery health over time.
Until now, users relied on third-party tools for this. With macOS 26.4, it’s built-in.
Why this matters
- Helps extend long-term battery lifespan
- Useful for desk setups where Macs stay plugged in
- Brings macOS closer to iPhone-style battery optimization
This is one of the most practical additions in this update, especially for MacBook users.
macOS 26.4 starts preparing users for the end of Rosetta 2
Another important change is how macOS now handles apps using Rosetta 2.
Whenever you open an app that depends on Rosetta 2 on Apple Silicon Macs, you’ll now see a warning.
Apple has already confirmed that:
- macOS 27 will be the last major release supporting Rosetta 2
So this change is clearly aimed at:
- pushing developers to update apps
- preparing users for potential compatibility issues
If you still rely on older Intel-based apps, this is your early signal to start looking for alternatives.
Safari’s compact tab view is back
Apple is also reversing one controversial design decision.
The compact tab layout in Safari is making a return after being removed in macOS 26.
For users who prefer:
- a more minimal browsing interface
- tighter tab spacing
this is a welcome comeback.
A niche but powerful upgrade for creators
macOS 26.4 also expands capabilities in Freeform, especially for Creator Studio users.
New additions include:
- access to premium images via Content Hub
- image upscaling tools
- integration with AI image generation models
This won’t affect every user, but for creators, it turns Freeform into a more serious creative workspace rather than just a brainstorming tool.
New emoji and smaller additions
As with most updates, macOS 26.4 adds new emoji, including:
- ballet dancers
- distorted face
- fight cloud
Not essential, but always a fun addition.
How to install macOS 26.4 RC
To install the update on your Mac:
- Go to System Settings
- Navigate to General > Software Update
- Enable Developer Beta updates
- Install macOS 26.4 RC
Make sure to back up your Mac before installing, especially if it’s your primary machine.
Should you install macOS 26.4?
macOS 26.4 is not a flashy update, but it solves real issues:
- fixes UI inconsistencies
- improves battery health management
- prepares users for future compatibility changes
If you’re already on beta, this is a safe upgrade. If not, waiting for the public release (likely very soon) is the better move.
