Mac Power Users

stats

Stats is the free open-source system monitor that lives in the menu bar. It charts CPU, memory pressure, network throughput, disk activity, sensors, and battery health with a tiny RAM footprint. Bluetooth battery readouts for mice, keyboards, and headphones reduce Control Center digging. Prefer Stats over leaving Activity Monitor open all day; prefer it over iStat Menus unless you need weather widgets and ultra-polished charts enough to pay. After a major macOS point release, re-check that battery cycle counts and sensor panels still render; GitHub issues usually appear within days if drawing regressions land. Grab builds from Homebrew or the project releases page, not random download blogs.

ice

Ice is the community-default menu bar manager after Bartender's turbulent years. It hides, shows, and reorders items, with hover-to-reveal patterns that keep the notch clear. Install via `brew install --cask jordanbaird-ice`. Tahoe required dedicated beta work when Apple changed menu bar APIs: use a current Ice build on macOS 26 rather than ancient forks. HiddenBar remains a simpler classic alternative; Bartender remains the paid automation heavyweight. After a Tahoe point release, confirm hover-to-reveal still works before you depend on it in a presentation; Ice tracks menu bar API churn closely. Prefer the jordanbaird-ice cask or the official GitHub release over mirrored DMGs.

monitorcontrol

MonitorControl sends DDC/CI commands over HDMI, DisplayPort, or USB-C so external monitors respond to Apple brightness and volume keys. Software dimming covers panels that ignore DDC. It is open-source, still maintained, and mandatory for anyone who has ever hunted physical buttons on the back of a cheap 4K display. Re-test DDC after OS updates. Brightness keys sometimes need Accessibility re-granted when privacy toggles reset. Stick to the MonitorControl GitHub release or Homebrew cask so you are not installing a fork that broke hardware write paths.

itsycal

Itsycal replaces the stock clock click-target with a fast mini calendar that reads native Calendar data (iCloud, Google, Exchange). Customize the menubar date format, highlight weekends, and jump to events without opening a full Calendar window or slogging through Notification Center. It remains free freeware from mowglii, not open source, but tiny and focused. Dato is the paid upgrade path for multi-time-zone power users. After calendar provider changes (iCloud, Google, Exchange), re-grant Calendar access if the mini view goes empty. Download from mowglii or the Homebrew cask rather than third-party mirror sites that repackage old builds.
