Explainer: XPC

fed.brid.gy/r/https://eclectic

<p>Apps you run have the user&#8217;s level of privileges, and must never be run as root. That poses a problem if that app needs to be able to do something requiring elevated privileges, such as those of the root user. The best solution to that is for the code that needs to be run as root to do so inside a completely separate process, a helper, specially created for that purpose. That in turn requires the app and its helper to communicate, so the app can pass its requests, and receive the responses when the helper has performed them &#8211; and that&#8217;s what XPC does.</p> <p>XPC stands for cross-Process Communication, and is based on Inter-Process Communication (ICP), part of macOS&#8217;s Mach inheritance. XPC works between a <em>client,</em> often an app although it could be any suitable binary executable like a command tool, and a <em>service.</em> Services are run by <code>launchd</code>, either according to a property list for a Launch Agent or Launch Daemon, or when requested by the client. While some services are helpers that work at higher privileges, most perform all sorts of other tasks that are more conveniently provided as a service.</p> <p>The client and service communicate by sending one another data structured in dictionaries. Typically, the client starts with a request, perhaps for the service to obtain some information that&#8217;s only accessible from a process with elevated privileges or with certain entitlements. The service might call a macOS API to f

Can you slim macOS down?

fed.brid.gy/r/https://eclectic

<p>Open Activity Monitor when your Mac isn&#8217;t doing a great deal and you&#8217;ll see hundreds of processes listed there. Even in a virtual machine with a minimum of services there are at least 500, and in a vanilla setup with no apps open a real Mac can exceed 700. Clearly some of those like WindowServer are essential, but aren&#8217;t there plenty we could do without? That&#8217;s a question I&#8217;m asked repeatedly, which this article tries to answer.</p> <p>One of the first problems when trying to identify which processes we could do without is knowing what each does, and how they&#8217;re interrelated. I doubt whether any individual in Apple knows them all, and trying to establish what some do would be a challenge. If we assume that we need to identify just 500 candidates, and each takes an average of one week to research, that would take over 10 person-years, by which time they would all have changed again. Studying 500 targets that are ever-changing simply isn&#8217;t practical.</p> <p>When problems get difficult, it&#8217;s often best to cheat, so I&#8217;m going to go for the low-hanging fruit and consider a well-known group of processes, those making Time Machine backups. I&#8217;ve been following these since macOS Sierra, and frequently study them in the log. They&#8217;re also good candidates for removal, as many folk don&#8217;t back up using Time Machine but use one of its alternatives. So some already have good reason to want to be rid of <code>backupd</
