What is Warashi?
A native menu bar app for Apple silicon Macs that measures CPU, memory, GPU, power, temperature, network, disk, battery and every app, keeps a year of history on your Mac, and turns it into answers: what slowed your Mac down, which app drained the battery, and what your next Mac needs.
When will it be available?
Soon. Join the waitlist on the home page and you'll get one email when it's out.
Which Macs does it support?
Macs with Apple silicon (M1 and later) running macOS 26 or newer. Intel Macs aren't supported.
Is Warashi free?
There's a free version for everyday monitoring. Warashi Pro is a one-time purchase, with no subscription, for up to two Macs. It adds alerts, Time × Cost, the process inspector, 12 months of history and an always up-to-date Upgrade Advisor.
How is it different from Activity Monitor?
Activity Monitor shows this second. Warashi remembers: it records history, groups helpers under their app, shows percentiles and peaks, tells you what each app cost and recommends your next Mac.
How is it different from iStat Menus or Stats?
Warashi is built around history and answers rather than many menu bar meters: one spirit in the menu bar, the notch and island, a window that tells your Mac's story, Time × Cost and the Upgrade Advisor.
Does Warashi slow my Mac down?
No. It uses about 0.16% of one core and around 25 MB of memory in the background, and it shows you its own cost so you can check.
Does my data leave my Mac?
Your history, app names and activity never leave your Mac. Warashi checks for updates, checks licences, and sends anonymous usage statistics (app version, macOS version, chip family and which features are used) to help improve it. See Privacy & your data.
Does it need special permissions?
No permissions to start. It never asks for Screen Recording, Input Monitoring or Full Disk Access. Notifications are asked for only when you turn on an alert, and the optional system-process helper only when you turn it on.
Can it show WindowServer and kernel_task?
Yes, with the optional helper in Settings › System. It only reads process counters and you can remove it any time.
Does it work without a notch?
Yes. On displays without a notch Warashi shows a small island at the top centre that works the same way. You can turn it off.
How much history does it keep?
Every 5 seconds for 24 hours, every minute for 30 days and every hour for 12 months, in a small local database.
Can I use it on two Macs?
Yes: a Warashi Pro licence works on two Macs, and you can move it by deactivating it on one.
How do updates work?
Warashi checks for updates daily (you can turn that off) and only installs updates signed by its developer.
How do I uninstall it?
Quit Warashi, turn off the system-process helper first if you enabled it, then move Warashi to the Bin. Its history lives in ~/Library/Application Support/Warashi if you want to delete that too.
