iStat Menus covers a huge range of stats, including CPU, GPU, memory, network usage, disk usage, time, battery, weather and more. iStat Menus 7 is a full reboot, sporting an all-new design with hundreds of big and small improvements. iStat Menus is unmatched in efficiency, and is the most CPU-friendly system monitoring app.
CPU and GPU
Highly detailed CPU info, with current usage for individual cores, history graphs, load averages, uptime, CPU frequency, and a list of the apps using the most CPU. Efficiency and performance cores can be styled differently. Plus, GPU processor, memory, temperature, and frequency on supported Macs.
Weather
Quickly glance at current conditions in your menu bar, or dive into an incredibly detailed hourly forecast and weekly weather overview, covering low and high temperature, wind speed and direction, chance of rain, humidity, dew point, UV index, pressure, visibility and more.
Memory
Extensive memory stats covering usage, history, memory pressure, compressed memory, swap, and a list of the apps using the most memory.
Rules
iStat Menus can notify you of an incredibly wide range of events, based on CPU, GPU, memory, disks, network, sensors, battery, power and weather. This lets you be notified when your public IP has changed, if your internet connection is down, if CPU usage is above 60% for more than 10 seconds, if disk space is low, or a near-infinite range of other options.
Disk usage and activity
See used space, free space, and disk activity in your menu bar. S.M.A.R.T. status monitoring, per app disk usage, and more detail for all your disks is only a click away.
Network
Keep on top of what’s being sent and received for all network connections with history graphs, current bandwidth usage, and a bandwidth breakdown for the top apps, as well as detailed connection info, bandwidth graphs, public and private IP addresses, and an internet connectivity indicator.
Battery and power
Detailed info on your battery’s current state and a highly configurable menu item that can change if you’re draining, charging, or completely charged. Plus, battery levels for Bluetooth devices.
Sensors
A realtime listing of the sensors in your Mac, including temperatures, hard drive temperatures (where supported), fans, CPU frequency, GPU frequency (where supported), voltages, current and power. Fan speeds can be controlled, and even switched or gradually ramped based on temperatures and battery state.
Date and time
Highly customisable menu bar clocks, a calendar with upcoming events, and world clocks with detailed sun and moon info. Each world clock can have a custom name, to make it easier to see the time for coworkers or family members.
Combined
Combined mode combines multiple iStat Menus items into a single menu bar item. You can choose what’s shown in the menu bar and what’s shown in the menu, allowing you to save space in the menu bar while still having access to all the information. It’s super handy on laptops.
