FreeFileSync for MAC
Free folder sync and backup app for Mac that copies only what changed. For private use; companies need the paid Business Edition.
FreeFileSync Overview
FreeFileSync is a folder comparison and synchronization app that creates and manages backup copies of your important files. Instead of copying every file every time, it finds the differences between a source and a target folder and transfers only the minimum amount of data needed. The basic steps are simple: choose the left and right folders, compare them, select the sync settings and press Synchronize.
It works with local drives and network shares, and it can sync with Google Drive and over FTP, FTPS and SFTP, with no artificial limit on the number of files. It detects moved and renamed files, can keep a history of deleted and updated files, and can compare files by content. The source code is under the GPL 3.0, but be aware of the terms of use: the standard and Donation editions are for private use only, and commercial, government and other non-private use requires buying the Business Edition. The Donation Edition adds a few bonus features, such as an auto-updater and parallel file copying, for people who donate. The installer and the app have no ads. Version 14.13 works around a macOS SMB driver problem with modification times. The FAQ lists macOS 10.12 through macOS 27 as supported, and the changelog records a native ARM64 build for Apple Silicon.

WhatCableUSB-C cables all look alike, but a charge-only USB 2.0 cable and a 240 W, 40 Gbps Thunderbolt cable are very different. WhatCable is a small menu bar app that tells you, in plain English, what each USB-C cable plugged into your Mac can actually do. For every port it shows a clear headline, such as Thunderbolt, display connected or charge-only cable, plus the cable's speed and power rating, the charger's power profiles and the connected device. When your Mac charges slowly, a banner points to the bottleneck, for example a cable rated below the charger.System Utilities- AlDenteAlDente lets you set a charge limit for your MacBook's battery. Instead of always charging to 100%, your MacBook stops at the level you choose, for example 80%, which can help the battery keep its capacity for longer when the Mac is plugged in most of the time. AlDente runs in the menu bar and works with most Apple Silicon and Intel MacBooks. It is made by AppHouseKitchen.System Utilities
DantroleneDantrolene is a menu bar app that stops your Mac's screen from locking while you are on your home Wi-Fi. You choose the home network once from the menu bar; in automatic mode the Mac stays unlocked there, and as soon as you join any other network, normal locking returns. The display still dims and goes dark after your usual idle time, and a touch of the mouse or keyboard brings it back without a password. Dantrolene steps aside when Zoom, a presentation or another app keeps the display awake.System Utilities
