Rounded corners, sharp tongues
Make macOS consistently bad (unironically)
Mac’s new round look ignites a corner war — rage, shrugs, and jokes
TLDR: A developer shared a way to make macOS 26 windows consistently extra‑rounded without disabling a safety feature. Comments split between shrugs, outrage at Tahoe’s pill‑shaped tabs, and jokes about a “theghostofsteve” site rating Apple moves as “genius” or “it’s shit,” proving tiny design tweaks spark big feelings.
macOS 26 (codename “Tahoe”) quietly changed how window corners look, and one developer went full chaos-mode: instead of flattening everything, they made everything more rounded for consistency. Their tweak, shared in this post, sidesteps riskier hacks that turn off Apple’s safety features and focuses on non‑Apple apps, leaving Safari’s wobbly look as the odd one out. The irony? The file’s nicknamed “SafariCornerTweak,” but it won’t touch Safari.
And the comments? Absolute corner court. Team Can’t See It rolled in first: post‑it and rafram both shrugged, basically saying “what corners?” Meanwhile Team Can’t Unsee It went scorched earth. pram torched Tahoe’s “ugly pill” tabs and called out Apple Music’s makeover with a dramatic “wtf happened there.” Even devs joined the brawl: skrrtww wondered if this trick even works with Apple’s newer app toolkit (translation: will the hack stick?).
Then came the meme energy: gnarlouse pitched a parody platform called “theghostofsteve” where every Apple decision gets rated “genius” or “it’s shit.” The vibe across the thread? Apple’s corner couture has split the room—half the crowd is measuring pixels, the other half is rolling their eyes, and one brave soul is just making the corners rounder until the chaos looks consistent. Welcome to 2026, where the hottest UI drama is literally… corners.
Key Points
- •The article describes inconsistent window corner radii in macOS 26 and seeks a consistent look without disabling SIP.
- •It proposes increasing and standardizing corner rounding rather than removing it, setting a fixed radius of 23.0 points.
- •An Objective‑C dynamic library overrides NSThemeFrame’s private methods to return fixed corner radii and sizes.
- •The tweak is restricted to third‑party GUI apps by checking bundle identifiers, excluding Apple system apps (com.apple.*).
- •Build instructions use clang to produce a universal .dylib (arm64e and x86_64) linked with AppKit; signing/storage steps are referenced.
