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.
