Ember is an open-source Mac utility for controlling the status light on a MacBook charger. Version 1.0.1 focuses on making the app easier to install, launch, and remove, rather than describing new light-control features. The release provides a disk image: users open it and drag Ember into their Applications folder. If they try to launch the app directly from Downloads, it now prompts them to move it to Applications first.
The update also addresses a problem starting Ember’s macOS helper, which could fail because the helper did not respond in time. Uninstallation now completes cleanly: Ember quits and moves itself to the Bin after removing its helper and login item, avoiding the previous hang during shutdown. Finally, the checksum file now contains plain file names, allowing users to verify downloaded files with `shasum -c` from the directory containing the download. These changes make the release primarily a practical fix for installation, background-helper startup, cleanup, and download verification.
