All fixes

A USB-C phone that charges intermittently, needs the cable wedged just so, or won't click in fully usually isn't a bad port or battery — it's compressed pocket lint at the bottom of the connector. Two minutes with a toothpick fixed it.

Your npm account uses a WebAuthn/Touch ID passkey for 2FA, so interactive npm publish can't prompt for a 6-digit OTP and the publish stalls or 401s. Publish with a Classic Automation token, which bypasses the 2FA prompt.

Adding a vhost for a brand-new domain and running caddy reload hangs indefinitely. Caddy is blocking on an ACME certificate for a domain whose DNS doesn't point at the box yet. Point DNS first, or reload — never restart — a shared Caddy.

The ext4.vhdx behind a WSL2 distro grows on demand but never shrinks on its own — deleting files inside Linux frees nothing on the Windows side. Trim inside the distro, shut WSL down, then compact the virtual disk with Optimize-VHD or diskpart.

"Add to Home Screen" on iOS shows a blank or screenshot icon instead of your app icon, even though the favicon works in the browser tab. iOS ignores SVG apple-touch-icons — you must serve a 180×180 PNG.

Moonlight pairs but fails to start the stream with "RTSP Error 60" on a headless Sunshine host. A zombie session or a hit start-limit is wedging the Sunshine service — clear the stuck session and restart it.

Music drops to muffled, mono, telephone-grade audio the moment any app touches the microphone. That's the Bluetooth hands-free profile taking over — classic Bluetooth can't do hi-fi audio and mic at once. Disabling the hands-free service keeps stereo quality, at the cost of the headset mic.

macOS sends a job and the printer ejects a single line of garbage characters — often the literal "%PDF-1.4" header — then stops. The CUPS queue fell back to a "Local Raw Printer" with no driver. Rebuild the queue with everywhere driver.

A Windows PC is reachable (ping succeeds) but SSH connections are refused because OpenSSH Server isn't installed/running and the firewall has no port-22 rule. Install the OpenSSH Server capability, start sshd, and open the firewall.

After an interrupted backup, Time Machine sat on "Preparing backup…" indefinitely. A leftover .inProgress bundle on the backup drive was the culprit — delete it and the next backup runs normally.

A USB NTFS drive with a 64 KB cluster size throws $MFT I/O errors and "unrecoverable error" on a Mac, but is perfectly healthy — the macFUSE/ntfs-3g driver just chokes on the large clusters. Repair it on Windows with chkdsk.

A high-end GPU artifacts just rarely enough that a technician will never catch it, so the warranty claim stalls. Force the fault to appear on camera with a targeted VRAM/power stress test, and rule out the look-alikes first.
