![]() ![]() ![]() As you very well know and is shown in the screenshot above, there can be various utilities put on the right hand side of the menu bar. There are in fact two types of such menu bar items, one known as NSMenuExtra's and another known as NSStatusItem's. Unless Apple makes the signature restriction optional, it is not clear that MenuMeters in its present form can ever be made compatible with OS X 10.11. ![]() The former are loaded and displayed by SystemUIServer, a process provided by the system. Although the restriction is similar, this is not directly related to 10.11’s System Integrity Protection (SIP, aka rootless) feature and disabling SIP has no effect on MenuMeters. The latter can be displayed by any app written by any developer. One good thing about the former is that you can rearrange them by ⌘-dragging the menu items. I have no idea why ⌘-dragging was not provided for the latter by the system. (On macOS Sierra 10.12, Apple finally implemented and enabled ⌘-dragging for all NSStatusItem's, including this port of MenuMeters. But this happened later than the need to port MenuMeters to El Capitan 10.11.)Īnyway, due to this better behavior of NSMenuExtra's, people often wanted to write their own. In fact until and including OS X 10.1, Apple allowed it. But since 10.2, Apple had a code that blocked SystemUIServer to load non-system-provided NSMenuExtra's. But until Yosemite, there was a known way to work around it, available as an open-source code as MenuCracker. Windows XP has a built-in performance monitor - its labeled as 'Performace' in the Admin tools menu. MenuMeters used this to inject their own NSMenuExtra's to SystemUIServer in fact MenuMeters' author is one of the main authors of MenuCracker.Įssentially, until Yosemite, SystemUIServer had a fixed list of allowed NSMenuExtras. MenuCracker was an NSMenuExtra that pretended to be one of those allowed ones, which, once loaded inside SystemUIServer, removed these checks, so that more NSMenuExtras can be loaded without any problem. In El Capitan, Apple added a more stringent check of the allowed NSMenuExtra's, and MenuCracker no longer works. So, how did I port MenuMeters to El Capitan, then? Well, I just gave up having ⌘-dragging. Then all I had to do was to, basically speaking, replace the occurrences of " NSMenuExtra" by " NSStatusItem", since the two APIs are almost the same.All UVM-owned computers running macOS 10.14 Mojave or older must be updated or replaced as soon as possible to comply with the University Information Security Policy. Meters labeled C, D, E, F can be used to view Tracks G. From the Apple menu in the top left corner of your screen, choose About This Mac. On Windows platforms, use the Safely Remove Hardware icon in the system tray.You’ll see the macOS name and version number, such as macOS Catalina 10.15.5 as well as your computer model and year. ![]()
