Whale for MAC
Free, open-source unofficial Trello app for Apple Silicon Macs: your Trello boards in their own window, with Home, Back and Forward shortcuts.
Whale Overview
Whale is an unofficial desktop app for Trello. It opens Trello in its own window, so your boards sit in the Dock and the app switcher instead of in a browser tab. It is built with Electron and shows the Trello website itself, so you sign in with your Trello account and everything you do happens on Trello. Whale remembers its window size and position, reopens the page you had open, and has keyboard shortcuts for going Home, Back and Forward. Links to other sites open in your normal browser.
Whale is free and open source under the MIT license, made by Shogo Sensui, and it is not made by or connected with Trello. Version 3.0.0 is a maintenance release. The Mac download is for Apple Silicon only, with no Intel build in this release, and the app needs macOS 12 or later. A warning before you install: Homebrew disabled its Whale cask because the app fails macOS's Gatekeeper check, so macOS may refuse to open it. The app needs an internet connection and a Trello account to be useful.

Time to LeaveTime to Leave is a desktop app for keeping track of your working time, laid out much like a time-card system. You log the time you started work, and the app works out when you should leave, taking into account the time you spent on breaks such as lunch, then notifies you when that moment comes. It needs no database setup: you install it and start punching in. You can log your day in a Day view or a whole Month view, and see your running balance of hours.Productivity

Press the spacebar on a .md file in Finder and Quick Look shows it rendered in color, and Finder shows generated thumbnails of your Markdown files. Open a file in the app and you get a live split: plain monospace source on one side and the rendered page on the other, with text selection and search that work across the whole rendered document.Productivity
MassReplaceItMassReplaceIt is a find and replace utility for many files at once. You choose the files or folders, type what to look for and what to put in its place, and MassReplaceIt searches either the file contents or the file names, such as changing the extension of hundreds of files in one go. Before anything is written you can preview the changes, and each search gives detailed results. Searches can be saved and used again, filters leave out files you do not want touched, and regular expressions handle patterns that plain text cannot.Productivity
TypeCueTypeCue takes the typing out of screen recordings, tutorials, webinars and live presentations. You write your demo as an ordered list of text blocks. During the take, each press of a global hotkey (Control-Option-X by default) types the next block into whatever field has focus, as real keystrokes at a human pace, with no typos and the same result on every take. Press the hotkey again while it types to stop it.Productivity
