Messages is getting undo and edit buttons to fix errors in or recall a recently sent iMessage, and there is an option to mark messages as unread. Handoff expands to FaceTime, allowing you to take calls on the Mac and transfer them seamlessly to the iPhone or vice versa. There's a Desk View that uses the Ultra Wide lens to show off your desk if you need to demo something, along with Center Stage and Studio Light, an effect that illuminates your face while dimming the background. The iPhone can be positioned on top of the Mac using a stand, and it is designed to connect automatically. The new Continuity Camera feature does away with the need for a poor quality built-in Mac camera because it allows you to use your iPhone as a webcam for your Mac. ![]() Stage Manager integrates with both Mission Control and Spaces, and it's simple to click right back over to the desktop. Apps and windows can be grouped together, so you can set up your desktop in the right way for your workflow. Stage Manager puts your main app front and center on the desktop, and tucks your other apps at the side for quick access when they're needed. With Stage Manager, Mac users have an all-new way of focusing on a task while leaving other apps at the ready. macOS Ventura is a significant update that introduces a new multitasking experience, overhauls multiple apps, and adds updated capabilities across the platform. The tool will also provide you with a simple classification of your network quality from Low, Medium and High.Introduced at WWDC 2022, macOS Ventura is the newest version of macOS, the operating system that runs on the Mac. In these scenarios, you not only receive a media stream, but also transmit one (for example, the feed from your webcam, screen sharing, or your microphone), so a proper network test needs to simulate both in parallel. In my opinion, this test is closer to some real-world use-cases, which are also mentioned in the official Apple support docs: video chat and voice calls. On the other hand, networkQuality measures the upload/download capacity and responsiveness in parallel by default (can be overridden to sequential mode with the -s argument). While these tools measure a few more metrics like latency to a target server, they both only measure capacity, and do this only in serial mode (the download and upload speed tests are done sequentially one after the other). Responsiveness: Low (103 RPM ) Why the macOS tool wins in some aspects The capacity is roughly the same metric you could expect from tools like from Netflix, or OOkla’s Speedtest. Upload/download responsiveness measured in Roundtrips Per Minute (RPM), which according to Apple, is the number of sequential round-trips, or transactions, a network can do in one minute under normal working conditions.Upload/download flows, this seems to be the number of test packets used for the responsiveness tests.Upload/download capacity (your Tx/Rx bandwidth essentially).You can simply call the executable networkQuality, which executes the following tests: It seems that Apple has quietly added a new tool in macOS Monterey for measuring your device’s Internet connectivity quality. However, today I want to focus on Transport layer metrics that can be collected with the new networkQuality tool. When we talk about wireless link quality, often we focus on Layer 1 properties like RSSI, noise, the Tx/Rx rate etc. Network quality can mean different things, depending on the context. ![]()
