CPU, RAM, SSD & Battery Widget

Only for Mac

Free

Mac

New: a one-click checkup of your Mac, Keep Awake, Mac Health, alerts and ten widgets. Still free, no ads, no data collected. Your Mac's vital signs, right in the menu bar. CPU, memory, GPU, network, disk and battery at a glance, plus a one-click checkup. Free and open source. No ads, no subscription, no data collected. SimplyBar is a lightweight system monitor for people who like to know what their Mac is doing without opening a heavy app. Show only the modules you need, hide the rest, and click any of them for a detailed window with history. NEW IN 1.1 • Diagnostic: one click tells you whether your Mac is fine, worth watching or has a problem, and why • Keep Awake: stops your Mac from sleeping, indefinitely or for 30 min, 1, 2 or 4 hours, with the display on if you like • Mac Health: heat level and, on a laptop, battery charge, maximum capacity, cycle count and condition • Alerts: a notification when a Bluetooth device runs low, the startup disk fills up or the Mac gets hot • Five new widgets, ten in total ON-DEVICE DIAGNOSTIC Rules check the processor, memory, disks, heat and batteries on every Mac and give a verdict: OK, Worth watching or Problem. Buttons take you to the right place: Activity Monitor, storage or battery settings, alerts, Keep Awake. On macOS 26 or later with Apple Intelligence turned on, Apple's on-device model writes the explanation, and you can ask questions such as "Why is my Mac slow?". It all happens on your Mac: nothing is sent over the internet. Every answer is checked before it shows. Without Apple Intelligence, the rules give the same verdict. IN YOUR MENU BAR • CPU: user and system load as bars, or one bar per core • Memory: app, wired and compressed memory, plus memory pressure • GPU: graphics usage • Network: live upload and download speeds, local IP address • SSD: used and free disk space • Bluetooth: charge level of keyboards, mice and trackpads that report it; headphones show up as connected • Health: a thermometer that turns yellow, orange or red as your Mac heats up • Diagnostic and Keep Awake Every module can be shown or hidden on its own. TEN DESKTOP WIDGETS CPU, Memory, GPU, Network, SSD, Storage (every disk, external drives included, in three sizes), Bluetooth battery, Mac Health, Diagnostic with its Analyze button, and Keep Awake, on or off in one click. LIGHT ON RESOURCES Hidden modules are only measured when a widget or an alert needs them. Launch at login is optional. FREE AND OPEN SOURCE • Free: no ads, no subscription, no in-app purchases • Open source under the MIT license, code on GitHub: https://github.com/Iliesseu28/SimplyBar • No data collected, no network access, no account • Runs inside the Mac App Store sandbox • Available in 50 languages Requires macOS 14 or later. AI-written diagnostic: macOS 26 or later with Apple Intelligence. Runs natively on Apple silicon and Intel Macs.
