DockZ 0.2.3

Changed

• Quitting DockZ (menu bar Quit, ⌘Q, the Dock, or logout) now shows a "Shutting down
  DockZ…" window listing the Docker engine and Linux machines being stopped, with a check
  as each one finishes, instead of seeming frozen for the seconds a clean VM shutdown takes.

• Monitor's disk card shows space used against the disk limit (orange from 80%, red from
  95%) instead of against the filesystem size, with how much space is free on the Mac.
  Settings shows the Mac's free space too.

Fixed

• The disk limit is now enforced when it is lowered. Before, the VM disk only ever grew, so
  a disk created at 64 GB kept using up to 64 GB after the limit was set to 16 GB. Apply &
  Restart now stops Docker, shrinks the disk offline to the new limit and starts Docker
  again. A safety copy is kept until the shrink succeeds. If the data does not fit, the
  disk is left as it is and the message says which limit would fit. DockZ shrink-disk
  does the same from the terminal while DockZ is closed.
• docker run (without -d), docker exec and other attached commands lost any output
  printed more than half a second after they started: sh -c 'echo start; sleep 3; echo end' showed only "start". The VM's socket relay closed the stream half a second after
  the docker CLI finished sending input. Existing VMs get the fix at their next start: DockZ
  now brings the VM's own DockZ service files up to date with the app on every boot (boot
  files excluded), so later fixes to them reach existing disks too.
• Opening DockZ while its menu bar icon is hidden (a crowded menu bar or the notch) did
  nothing, so the app looked frozen. Opening it again from Finder, Spotlight or Launchpad
  now always shows the dashboard (restoring it if minimised), and a launch you start
  yourself opens it too; only Launch at Login still starts quietly in the menu bar.

Install

Open DockZ-0.2.3.dmg, drag DockZ to Applications, then launch it.
Requires macOS 15+ on Apple Silicon. First launch builds the Docker VM image (a few minutes).

Or with Homebrew:

brew tap nextage-soft/dockz https://github.com/nextage-soft/dockz
brew install --cask nextage-soft/dockz/dockz

This build is not notarized. On first launch macOS blocks it: open
System Settings → Privacy & Security and click Open Anyway for DockZ.

Signing it yourself or with your own certificate: deployment guide.
