Liquid Glass, solid backlash
Block the "Upgrade to Tahoe" Alerts
Mac fans find a sneaky way to silence Tahoe nags — and call it a downgrade
TLDR: A crafty profile—and a bug—lets Mac users delay Apple’s “Upgrade to Tahoe” nag for 90 days at a time, sparking cheers. But the comments are a roast: many call Tahoe worse than Sequoia, gripe about glitches, swap a one-line hack, and fear Apple will slam the loophole shut.
Apple diehards are quietly celebrating a new “shh” button for their Macs: a 90‑day block on those relentless “Upgrade to Tahoe” pop‑ups. The twist? It works thanks to a quirky bug in macOS 15.7.3 that lets the block keep rolling, even though it wasn’t supposed to. The crowd is split between two camps: the meticulous tinkerers using a configuration profile from the Stop Tahoe Update project, and the “one‑liner rebels” dropping a simple command in the Mac’s command line to punt the alert into 2030. Either way, the nag is gagged—for now.
And the mood around Tahoe? Spicy. Multiple users say it’s a downgrade from Sequoia, with one lamenting slow animations and another fuming about a weird “drag the corner of a window” glitch. Some are stuck running both: Tahoe on a work laptop, Sequoia on the home Mac, just to stay sane. One anxious buyer wonders if a new MacBook will trap them on Tahoe forever. Meanwhile, the Linux crowd saunters in with a victory lap, calling Apple’s software slump a mirror image of the old days—great hardware, meh software. The jokes write themselves: “Liquid Glass” looks? More like Liquid Backlash. The only real fear now: Apple fixes the bug and the nags come roaring back.
Key Points
- •A configuration profile can defer major macOS updates (like Tahoe) for up to 90 days, suppressing upgrade notifications.
- •A bug in macOS 15.7.3 causes the 90-day deferral to behave as a rolling period rather than being tied to the release date.
- •The Stop Tahoe Update GitHub project provides a mobileconfig profile to implement the deferral.
- •Setup steps include cloning the repo, making scripts executable, and inserting two UUIDs into deferral-90days.mobileconfig.
- •Final installation requires approving the profile in macOS System Settings → Privacy & Security → Profiles, as the profiles CLI no longer installs profiles.
