# Activity+ changelog ## 0.2.6 (2026-09-28) See how fast your Mac is charging, and why it isn't. **New** - The Battery page shows the charging speed in watts and percent per hour, and when the battery will be full - Power flow: what the adapter delivers, what the Mac itself uses, what goes into the battery, and what is lost converting the adapter's voltage - Power adapter: its rating, the voltage and current it agreed on with the Mac, and every voltage a USB-C adapter offers - This charge: percent and watt-hours gained, average and peak watts, and the charging curve - Battery health in mAh (now, full, new) and charge cycles against the number the battery is rated for - Why the battery is not charging: full, held at 80 % by Optimized Battery Charging, your charge limit, battery temperature, or an adapter that cannot keep up with the load. Reasons the battery controller reports without a documented meaning are shown as they are, not guessed - When charging is slow because the Mac itself uses most of the adapter's power, the page says so - Menu bar: a battery item can show watts while charging or discharging (+19 W) instead of the percentage. The panel shows the charging speed, the time to full and how much of the adapter is in use - The history keeps the battery's and the adapter's watts per minute - `aplus --json` and `aplus mcp` include the charging details, so an AI agent can answer "why is my Mac charging so slowly?" Requires macOS 15 or later on Apple silicon. Notarized by Apple. ## 0.2.5 (2026-09-26) Trace a spike back to the process behind it. **New** - The history now keeps the busiest child processes of each app (every 5 minutes), so a spike in "Terminal" shows it was `node vite` or `cargo build`. Point at the history chart to see who was busy at that moment, or expand an app in "Apps that used the most" - Alerts name the process when an app has several: "Terminal is keeping the CPU busy … Mostly node vite (pid 4312)" - Recording sessions show the main process of each app - `aplus mcp`: the history tool lists the processes behind the top apps and answers "what was busy around 14:30?" **Privacy** Command lines are shortened to the program and its first arguments; anything that looks like a token, password, key or credential in a URL is blanked before it is stored. It stays on your Mac, like the rest of the history. Requires macOS 15 or later on Apple silicon. Notarized by Apple. ## 0.2.4 (2026-09-26) New measurements and a few conveniences, picked from what Mac users ask for most. **New** - **Recording sessions**: start a recording before a build, a render or a slowdown (in the window or from the menu bar), see CPU, memory and power over time with the top apps, compare two sessions, export CSV or JSON - **Performance or efficiency cores** per app, with instructions per cycle, on the CPU page and in the process inspector - **Neural Engine memory** per app on the Memory page, so Core ML and local models show up - **Connection quality** (off until you turn it on): latency, jitter and packet loss to your router every 30 seconds, optional public host of your choice, outages in the history - **Displays** on the GPU page: refresh rate, resolution, HDR, ProMotion, and a warning when a monitor runs below the rate it can do - **Power adapter** on the Battery page, and an alert when the battery drains although the Mac is plugged in - **Show Activity+ in the menu bar, the Dock or both**; a click on the Dock icon opens the window - **Settings export and import** (Settings → General → Backup) Requires macOS 15 or later on Apple silicon. Notarized by Apple. ## 0.2.3 (2026-09-25) Safety and accuracy release, after an independent code review. **Safer** - Uninstall only ever touches folders directly inside your Library, and leaves folders that another installed app also uses - Quit and Force Quit check that the process is still the one you saw, and only quit the copy of an app you picked - "Stop idle dev servers" counts only the idle time Activity+ has actually watched - Turning a startup item on now asks first, like turning it off; turning one off also works when it is not loaded right now - Your public IP is looked up only at api.ipify.org, exactly as the privacy notes say **More accurate** - History totals weight each sample by the time it covers, and a sample right after sleep no longer counts the whole night - Disk throughput is counted per drive, so drives that come and go cannot cause spikes - The code signature check in the process inspector also verifies the program code - Muting an app also covers audio processes it starts later (beta) - History older than 30 days is removed daily, not only at launch Requires macOS 15 or later on Apple silicon. Notarized by Apple. ## 0.2.0 (2026-09-25) First public release. **Highlights** - Processes grouped by app, with per-app CPU, memory, GPU, disk, network and energy - A menu bar you build yourself: any number of items, eleven styles, your colors - "Why is my Mac slow?" in plain words, with a fix for each finding - 30 days of history, alerts, unusual-activity and memory-leak detection, a weekly report - Every drive with SMART/NVMe health, CPU and GPU clocks, GPU power, several hundred sensors - Dev servers by project, connections per app, process inspector, sleep & battery drain - Automations that ask before they act - `aplus mcp` for AI agents (read-only) Requires macOS 15 or later. Notarized by Apple. Tested on Apple silicon. Beta: per-app volume, freeze detection, accessory batteries.
