What’s new in v1.13.0

Minor Changes

  • The Overview is a page you can work through now. What needs your attention sits at the top as a row of cards you move through one at a time, each saying what it is and what doing it costs. The readings below are tiles you can resize — bigger for the ones you care about, smaller for the rest — and the heading stays put as you scroll, shrinking out of the way instead of scrolling off.
  • The menu-bar panel shows the same card the app does. It used to draw its own version of the same reading, so the two could quietly disagree about the same Mac. There is one card now, in both places.
  • Plumby's face has five expressions, eyes as well as mouth, and they follow what your Mac is actually doing.
  • Text that was invisible is visible again. On some cards a label was drawn white on white, a gauge was drawn outside the space it had reserved and clipped, and the placeholders shown while a reading loads were the wrong shape for the card they stood in for.
  • The Overview costs much less to draw. The heading redrew sixty times a second whether or not anything had changed, and the list of things needing attention was swept twice on every update instead of once. On a laptop that is battery you keep.
  • "Keeping your Mac awake" and its explanation can no longer disagree. How long an app has to hold your Mac awake before Plumby names it was decided in the part that reads the system log rather than the part that decides what to show you, so the number and the sentence about it could drift apart.
