Hidden macOS 26 Features, Homebrew Upgrades, and VPN Gotchas
Mac Geek Gab — Apple Tips, Tricks, and Troubleshooting
Tailscale Device Expiration Pitfall
Dave warns that Tailscale device authentications can expire and recommends disabling expirations to avoid lockouts.
You dive straight into practical macOS and workflow wins, starting with macOS 26’s new ability to record video by window and moving quickly into keeping your Homebrew setup clean, current, and fast. You learn how simple display resolution tweaks can hide the MacBook notch or eliminate it entirely, and why audio problems like AirPods mic failures often come down to overlooked system behavior. Along the way, you’re reminded to stay alert to sneaky gotchas like expiring Tailscale devices, VPNs that never fully disconnect, and cables that quietly become the weakest link. Don’t Get Caught assuming the obvious is working as expected.
Then it’s on to listener questions that hit real-world pain points: avoiding international cell charges even when using an eSIM, understanding why not all MVNOs are equal, and keeping vacation photos manageable by killing duplicates before they pile up. You dig into OS version mismatches, whether AI actually helps tech support when used correctly, and why asking AI to explain the “why” matters.
Cool Stuff Found rounds things out with tools for sleep and stress tracking, app update management, USB speed visibility, smarter System Settings navigation, notch-aware utilities, nostalgic screen savers, and shortcut mastery. It’s a fast-moving episode packed with ways to tighten your setup, reduce friction, and stay one step ahead.
Happy new year, y’all! See you in 2026! (don’t worry, that’s next week, right on schedule!)
