v4.2.0

A menu-bar app whose menu bar needed a window.

Set SiliconScope to launch at login and it came up as a Dock icon with an empty menu bar — no CPU, no GPU, no anything — until you clicked the icon and a window appeared. The sampling loop that draws the menu-bar items was started from the dashboard window, so with no window there was nothing to draw from.

Startup now belongs to the app rather than to a window, and a login launch no longer pulls that window in front of what you were doing. Two things had been quietly riding along: "Show Dock icon" off still showed one at login, because the setting was applied from the window that never opened — the exact mode Settings recommends was the one that did not hold — and a Mac with Share this Mac enabled stayed invisible to its own fleet until somebody opened its dashboard.

SiliconScope was knocking on ports nobody asked it to

• It sent GET 127.0.0.1:8080/metrics and :8081/metrics every three seconds on every Mac — no runtime detection in front of it, whether or not any AI runtime was installed, roughly 57,000 requests a day — and whoever else owned 8080 received all of them. Three separate places guessed at a port instead of looking; they now take the one a llama.cpp process was actually observed on, and the watcher no longer carries a list of ports to try, so it cannot reach anything nobody pointed it at. Measured on a machine with no llama.cpp: 16 requests to each port in 45 seconds before, zero after. (#53, reported by @csthenry, who also traced it to the right line)

Also fixed

• The dropdown opened on the wrong desktop. With a full-screen app in front, a menu-bar icon still responded to the click but its panel opened back on Space 1 where you could not see it. (#49, reported by @blackbox-zz)
• A light-mode button in a dark window. SiliconScope's window is unconditionally dark but had never said so, so on a light-mode Mac macOS drew the chrome for a light app over it — a pale sidebar-toggle chip and a title in dark-on-dark. The menu-bar icons still read the real menu bar, so they keep matching your wallpaper rather than the app. (#50, reported by @chapter09)
• Fleet machines can be renamed, and the list is finally in an order you can read. "It seems random." It was not — the list has always been alphabetical, but it sorted on the mDNS instance name while showing the machine's hostname, and those are different strings. An order keyed on something you cannot see is indistinguishable from no order. One name now does both jobs, and you can set it yourself: right-click a machine → Rename…. Renaming never touches the machine's pairing. (#55, asked for by @parkamonster)
• --uninstall reinstalled the agent. The one-line installer hands macOS off to the Mac installer, and the handoff dropped the flag you typed. The uninstall itself had been there all along; it was never reached. The README had the mirror image of the problem — install was a copy-button block while uninstall was prose with the URL trimmed to …/ — so it is a block of its own now, in all six languages. (#54, reported by @parkamonster)
• mlx-dspark is recognised, and it is followed to the --port it was actually started with. A Homebrew-installed Ollama was invisible for a related reason: its server carries neither /Ollama.app/ nor /.ollama/ in its path, so only its model-loading child was ever detected.
• Memory bandwidth stayed at 0 on an M3 Max under macOS 27, where PMP0 exposes only the aggregate histogram. (#46, reported by @Collinw24)
• An unpopulated IOReport energy rail reports INT64_MIN, which was being summed as a real reading. (#42, fixed by @YuriNachos)
• A battery whose capacities cannot be read reported "0 % — Normal"; unknown health now says so instead of claiming a healthy cell.
