Mac system performance monitor widget

If you have hundreds or more fonts to manage, consider using Font Book or a third-party font-management application to create, enable, or disable font collections when required. At a minimum, run the Mac OS X maintenance scripts regularly. Some Macintosh computers can decrease the processors speed to conserve energy. Note that:.

Activity Monitor is the place to start when troubleshooting performance problems. Menu extras are the icons on the right side of the Apple menu bar other than the Spotlight icon Leopard, Tiger. Third-party menu extras that use an active Internet connection can result in very high CPU usage if the network connection becomes busy or blocked. The chances of this increase if you are simultaneously using streaming media and a menu extra that requires an Internet connection.

Quitting your third-party menu extras should resolve the problem. Maintain ample free space on your startup disk Mac OS X makes extensive use of Virtual Memory VM , which requires free disk space on your startup disk, aka your boot volume. Turn off the eye candy While I imagine everyone is impressed the first time they see a window minimized to the Dock with the Genie effect, this entertainment has a performance cost. Select Scale Effect in the Minimize Using field. Deselect the Animate Opening Applications option.

Disable window effects Tools such as Cocktail and TinkerTool provide options to disable effects, such as zoom and rectangle, that appear when windows and files are opened and closed. The actual settings these utilities change are already available in Mac OS X but are "hidden" as there is currently no provision for changing them in System Preferences. Avoid using an animated desktop background While entertaining, an animated desktop background steals cycles from other processes on your Mac.

It is better to have a static picture as your desktop background if performance is important. It is not so much displaying the visuals as the computational effort needed to synchronize them with the music in real time that makes them so processor-intensive. Under Mac OS X You can reclaim these resources by closing nonessential widgets.

To close a widget: Open Dashboard. Press and hold the Option key.

How soon after starting your Mac can you begin to use it? Is it slow to start up first thing in a morning? What is it doing? At the end of the day, is it OK to turn off or restart or is the Mac still doing important processing or disk tasks? You just don't know what is happening behind the scenes.

It is therefore useful to keep an eye on what it is doing and you can easily add activity monitors to the right side of the menu bar at the top of the screen that show CPU usage, memory used and free, internet or LAN activity, and disk usage.

It is not the most comprehensive utility of its type and it does not have the most features, but there are a couple of reasons why you might prefer it to more modern alternatives. The other is that is lightweight and uses very little memory or processing power. Typically it uses around 0. It has a great display of resource usage in the menu bar.

I had to abandon it from El Capitan onwards, but someone has tweaked the code and made it compatible with modern versions of macOS, including Mojave. Here is it running on Mojave with the dark theme selected and a few of the optional features enabled in its settings. The features have changed very little and it just works on Mojave now.

Double click the zip file to extract it and a file called MenuMeters. Double click it t install it. System Preferences opens and a message appears saying that it must be installed.

Publisher's Description

When given a choice of installing something for yourself or for all users, it is usually best to install it just for yourself. Click Install. Because this file was not downloaded from the Mac App Store, a warning message is displayed. I checked it out at the VirusTotal website, which is always recommended, and it was given a clean bill of health, so go ahead and click Open.


MenuMeters appears as an extra item at the bottom of the System Preferences window. This is where it is configured. Click it to open it. MenuMeters adds up to four optional items to the menu bar: CPU, disk, memory and network. Each of these is configurable and you can choose from several different display styles depending on how much information you want to see.

You can see two examples of these optional indicators in the screenshots above. The other items, disk, memory and network, also have numerous display options. The colours of each item in the menu bar can be changed. The defaults work fine with the traditional light macOS interface, but are too dark for the dark theme. Select a colour at the bottom and it can be changed though.

I selected lighter colours to make them easier to see with the dark theme.

The menu bar display indicators instantly tell you how hard the Mac is working behind the scenes.
