At the time of writing, developer Alex Harper has put a warning on the MenuMeters website that reads as follows:ĭue to new Apple-enforced code signature restrictions, MenuMeters is not compatible with the OS X 10.11 “El Capitan” public beta. I still use MenuMeters on all my PowerPC Macs.īut after upgrading to Mac OS X 10.11, I discovered that MenuMeters is not compatible with the latest version of the operating system. In my case, I’ve always been interested in one thing - checking network activity, and MenuMeters can simply show the network throughput as bytes per second (or even just arrows, if you really want the simplest, most minimalistic option). I hate cluttering the menubar with icons, so it’s important that a monitoring tool let me hide everything I don’t need to see. I like it for its unobtrusiveness, level of customisation and general lightness. Every time a major Mac OS X release came out, one of the first things I used to do after upgrading was checking whether MenuMeters would work. It has been around since Mac OS X 10.4 Tiger, and it’s always been my preferred software in its category. Patches cheerfully accepted.MenuMeters is a set of CPU, memory, disk, and network monitoring tools for Mac OS X. Even better, since this is open source, you can fix the bug yourself. That said, if it causes you problems I'd like to hear about it so that I may be able to track down the bug. MenuMeters comes without warranty or support. Interface information is gathered from the SystemConfiguraton framework and thus is MacOS X network location aware (to prevent interfaces from appearing in this menu see the FAQ). The Net Meter menu shows current interfaces and their status. Scaling can be done on the basis of actual link speed reported by the network interface or peak traffic and can use one of several scaling calculations. Both the arrows and the graph are scaled using a user-selected scaling factor and calculation. The Net Meter can display network throughput as arrows, bytes per second, and/or as a graph. The Memory Meter can optionally display a paging indicator light. The Memory Meter menu shows a breakdown of current memory usage and VM statistics. The Memory Meter can display current memory usage as either a pie chart, thermometer, history graph, or as used/free totals. The Disk Meter menu shows volume space details for local drives (it does not display mounted network volumes for speed reasons). It is hotplug aware, and will show activity on FireWire and USB disks as they are mounted. The Disk Activity Meter displays disk activity to local disks on the system (anything that is a IOKit BlockStorage driver). The menu for the CPU Meter contains several pieces of information I like to have a single click away (uptime, load average, open Process Viewer, open Console). It can also graph user and system load and display the load as a "thermometer". The CPU Meter can display system load both as a total percentage, or broken out as user and system time. This means they can be reordered using command-drag and remember their positions in the menubar across logins and restarts. The MenuMeters monitors are true SystemUIServer plugins (also known as Menu Extras). Those monitors which used the menubar mostly used the NSStatusItem API, which has the annoying tendency to totally reorder my menubar on every login. Most were windows that sat in a corner or on the desktop, which are inevitably obscured by document windows on a PowerBook's small screen. Although there are numerous other programs which do the same thing, none had quite the feature set I was looking for.
