iStat Menus features
CPU & GPU
All you need to know to be sure everything’s alright: Mac CPU usage and overall activity. Quickly check on it without opening the app — the menu bar icon will show you the info. It’s real-time and you can view your Mac’s process monitor by individual cores or by all cores combined.
Memory
You can view memory stats in any form you prefer — as a pie chart or bar graph. Plus, you get a list of apps using the most memory, so you know which to quit when it gets tight.
Network
A realtime graph to keep on top of what’s being sent and received for all network connections, including a bandwidth breakdown for the top 5 apps.
Disk usage & activity
One of the main Mac performance monitors is naturally disk usage and general disk activity. Apart from general info on both HD and network drives, iStats gives you a variety of read and write indicators and S.M.A.R.T status monitoring.
Sensors
A realtime view of temperatures, hard drive temperatures (where supported), fans, voltages, current and power. Fan speeds can be controlled, with different rules when on battery power, if you’d like.
Date & time
Most of daily needed info in super detailed form: date, time, and an extensive weather for Macs module with temperature calendar, moon phases, wind speeds, dew points, and more. iStat Menus also has a world clock to show you not just the time, but sunset and sunrise times all across the globe.

App version: 7.20
in love with this, i work across a lot of timezones and this has THE MOST compact way to display multiple times in the menu bar and it’s incredibly customizable. also the network monitor and cpu monitors in the task bar are absolute irreplacable at this point. 10/10.
