5 releases so far, newest first. Bubo watches all night; this is what it shipped. Grab the latest for Apple Silicon or Intel.

v1.4 28 Jul 2026 Latest

The panel got out of its own way. It opens flat under the menu bar and as tall as the screen allows, and the readings inside it now say what they are measured against.

  • new Check for Updates in the right-click menu, comparing the latest release against the build you are running
  • new Report a bug opens a report form with your Bubo build, chip, RAM and macOS version already filled in
  • changed Panel opens flat under the menu bar and as tall as the screen allows, instead of a fixed height that hid the lower half behind a scroll
  • changed Efficiency and performance rows draw a bar per core and end in that tier's usage and speed; the separate core row is gone
  • changed Fan reads against its own floor and ceiling, on a row under the temperatures
  • changed Memory leads with used against total, and DRAM bandwidth moved above the bar, out of the app / wired / compressed / cached list
  • changed Power rails split the draw by rail on their own bar, next to battery

v1.3 27 Jul 2026

Bubo names the cause now. The panel used to show readings and leave the interpreting to you. It now says what is likely wrong and one thing to do about it, in a sentence.

  • new Diagnosis banner: the likely cause and one suggested action, in plain words
  • new System uptime in the panel header
  • changed Panel draws a solid background instead of the popover material
  • fix Memory matches Activity Monitor, per app and system used
  • fix Battery shows the charge macOS shows, not the raw mAh ratio
  • fix A busy app in front no longer hides a runaway in the background
  • fix Memory pressure follows the OS verdict instead of two guessed thresholds
v1.2 26 Jul 2026

Clearer at a glance. Full-word CPU tiers, a plain-language throttling badge, and a memory bar that shows what your RAM is actually spent on.

  • changed CPU cores named efficiency / performance, one per row, with temp, hotspot and pressure under the bar
  • changed Status badge reads throttling in plain words when the Mac runs hot, not "thermal serious"
  • new Memory broken down into app, wired, compressed, cached and free
v1.1 25 Jul 2026

Intel is in. Bubo now ships a native build for Intel Macs alongside Apple Silicon.

  • new Native Intel build, Bubo-intel.dmg
v1.0 24 Jul 2026

First light. The whole panel in your menu bar, and one click to quit the app dragging your Mac.

  • Top apps: the eight heaviest processes, grouped per app, one-click quit
  • CPU, memory, GPU and fan, battery, network and disk
  • Power rails and temperatures on Apple Silicon
  • Purge disk cache, or quit every heavy app at once
  • Native Apple Silicon, no daemon, no sudo
