MacSystem Monitor Apps
These stack alongside your notch app.
Menu bar managers and monitors — the adjacent species. Notched MacBooks made menu bar space scarce, which turned organizing, hiding, and styling status items from a nicety into a necessity. All of these coexist with any notch app.
Menu bar apps are the notch’s adjacent species: managers that organize, hide, and style your status items, and monitors that put system stats one glance away. The notch made menu bar real estate scarce — on a 14-inch MacBook a crowded bar simply runs out of room — which turned these from nice-to-have into near-essential.
Bartender is the long-running incumbent; Ice is the free, open-source challenger that’s become the default recommendation when you’d rather not pay; Hidden Bar is the simplest possible toggle. On the monitoring side, iStat Menus is the reference for tasteful information density, with Stats as its free open-source counterpart.
Everything here coexists with any notch app — this is stack territory, not swap territory.

Mac system monitor apps — questions people ask
How do I hide menu bar icons on a Mac?
Bartender (paid, most powerful), Ice (free, open source), or Hidden Bar (free, simplest) all tuck status items out of sight.
What’s the best free Bartender alternative?
Ice — actively developed, open source, and the community’s default recommendation for menu bar organization.
Why did the notch make menu bar managers necessary?
Notched MacBooks lose the center of the menu bar, so status items run out of space sooner — managers reclaim that room.
What’s a good menu bar system monitor?
iStat Menus if you want the most polished option, Stats if you want free and open source.
