I got my first apple product at the start of 2007, shortly after receiving an instalment of my student loan. My Black MacBook. It was top of the range at the time with a Core 2 Duo processor and one whole Gigabyte of RAM (which I later upgraded to two). At the time I didn’t know anything about Mac’s so I let a friend of mine (who later betrayed Apple for Linux) get it all set up. Among the various pieces of software that he installed, one of them was a very handy app called MenuMeters. The idea of MenuMeters was that it kept an eye on your system for you – your CPU load, RAM usage, Networking utilisation and a few other bits and pieces.
I took it for advantage that it was the only tool of its kind until recently discovering that iSlayer (the guys behind the very cool iStatPro dashboard widget) have a product that is quite similar – iStat Menus.
So this left me with a bit of a dilemma – do I keep using old and faithful MenuMeters, whose core functionality has remained the same for 5 years now or move to something a bit newer and bit more flashy. Time to weigh up the differences. MenuMeters is incredibly easy to install. Open the .dmg and double click the .prefpane. This installs MenuMeters into your system preferences, making it incredibly easy to activate and customise.


Within the preferences you can activate CPU, Disk, Network and Memory (RAM) monitoring – which, after choosing your preferred layout, looks a little something like this:

I have chosen the graph layout for my CPU and it shows each of my 8 cores – this takes up quite a bit of room on the Finder bar, but you can also display just percentages over even one average for all cores.

The Network tool gives you an overview of your transmit and receive speeds as well as giving you statistics from each of your networking devices in a clear manner.

The RAM tool lets you see at a glance how much RAM you have available/used, but also gives you a more in depth look at how your RAM is being utilised.

Finally the Disk tool (one I rarely use) lets you see when there is disk activity (read or write) alongside the drives currently mounted, their mount point and filesystem.

So there it is – good trusty old MenuMeters – now let’s look at iStat Menus 3.
iStat Menus runs as an application and it’s install is as easy as unzipping and placing in the Applications folder. Upon launching it for the first time we are invited to install the application before being allowed to customise it. The first thing to notice is that this is only a trial version and that fully featured version will cost $16 (£10). As a result I am expecting very good things from this application.

Straight away you can see that there are many more tools to choose from. In addition to that of MenuMeters, iStat also has Disk Usage, Temperature (and other built in sensors), Battery and Date & Time (if you feel the need to change from the Mac default clock). Looking first at CPU – iStat has the same features as MenuMeters but gives us the ability to fully customise the appearance. If we wanted we could have bars, graphs, piecharts and percentages if we wanted, although I feel that with 8 cores, I might run out of room. The same customisation applies to the rest of the monitoring tools but beyond that not much is different. We still have the used/free totals for RAM and the bandwidth utilisation for Networking.

The real difference comes when we look at the drop down menus each of the tools has to offer. The information available is much clearer and well presented. For the CPU you can see the history of all your cores, even if you only have an average displayed. It also shows us the top processes as well as the GPU memory usage and system active time as opposed to just uptime.

The RAM tool lists the top 5 processes so that you can easily clean up memory space, as well as a RAM usage history.

Disk Activity gives us a read/write history of the main drive as well as current speeds, while Disk Usage gives us the free/used space per drive. Note that here we do not have the drive mount points although as the drives are always mounted in the same place (/Volumes) it isn’t really a useful tool to have.

Finally the Network tool gives a detailed graphically representation of transmit/receive, but unlike MenuMeters, hides the inactive interfaces (you can see here that as bluetooth is turned on, it is displayed).

The addition of a sensors tool gives an incredible amount of information of system temperatures. Not only can you display the value of each sensor separately if you wished, just /look/ at how many there are to choose from. You can monitor temperature, voltage, fan speed and even current and power. An incredible amount of information – especially if you are an enthusiast.

Finally, iStat has one more trick up it’s sleeve with the combination tool – this allow’s you to display icons and menus as separate entities; If you just want CPU icons you can have them, or if you want the sensors menu but no icons, you can have it. This means you can thoroughly customise all the tools you want to see, along with all the ones you want at your fingertips, but not taking up space on your Finder bar.



So what’s the tally? Well MenuMeters has great functionality for a free system – its lightweight, customisable and unobtrusive. iStat, however, has incredibly detailed information, great looks and a plethora of customisation options but it does cost £10 after the 14-day trial period.
So the choice is yours, but for me, I have the feeling iStat might be sticking around…
