I installed it but I don't see a window
That's expected. xHelios has no window and no Dock icon — it lives entirely in the menu bar at the top right of your screen. Click its readout to open the stats popover.
The menu bar item is hidden
If your menu bar is crowded, macOS may hide items. Hold ⌘ and drag menu bar icons to reorder them, or quit apps that take up menu bar space. On Macs with a notch, a very full menu bar can push items behind it.
How do I change what's shown?
Click the menu bar readout. In the popover you can toggle CPU, RAM and Network individually, and choose between the compact, detailed and capacity display styles.
Why do the numbers differ from Activity Monitor?
xHelios samples system-wide counters on a short interval and reports the average over that interval, while Activity Monitor uses its own sampling window and memory accounting. Small differences are normal.
Does it slow down my Mac?
It is designed not to. Native Swift, no dependencies, and it reads a handful of kernel counters every couple of seconds — a negligible load.
Does it send my data anywhere?
No. xHelios makes no network requests and collects nothing. See the Privacy Policy.
How do I quit or uninstall it?
To quit: click the menu bar readout and choose Quit xHelios. To uninstall: quit the app, then drag xHelios from your Applications folder to the Trash.
Requirements
macOS 13 Ventura or later, on Apple silicon or Intel.
