A full Trash folder quietly eating disk space is easy to forget about until storage runs low — this macOS menubar trash reminder app is built around exactly that blind spot, turning an overflowing Bin into something visually impossible to ignore.
The mechanism is deliberately playful rather than a plain notification: once a user-configured disk-space threshold is crossed, animated flies start appearing around the menubar's bin icon and multiply hourly the longer it goes unemptied, with hovering over them scaring them off temporarily. It's less a system alert and more a small, mildly annoying nudge that gets more annoying the longer it's ignored — which is presumably the point.
Running that check requires accessibility permissions to locate the Bin's position and full disk access to calculate its size, both fairly standard asks for a utility that needs to watch a specific folder continuously. The app is credited to two named developers, Leon Schrijvers and Rik Schennink, and states it's 'Powered by PQINA' — small but specific attribution details for what's otherwise a lightweight, single-purpose tool. The site also points to Hidden Bar as a companion option for anyone who wants to keep their menubar tidy while still running BananaBin in the background.
A few things are worth knowing before installing: it currently only tracks local Trash, with iCloud and external-storage support listed as under development, and it supports macOS Sonoma (14) with likely — not confirmed — compatibility on Sequoia (15); older macOS versions and Windows aren't supported at all. The page also links to a purchase page without stating a price directly on the reviewed page.
Not yet — the site states BananaBin currently only takes into account local trash, with iCloud and external-storage support listed as under development.
Yes — accessibility permissions to locate the Bin's position on screen, and full disk access to calculate how large the Bin currently is, both required for the threshold-tracking to function.
Only once the Bin is emptied — the site states the flies multiply hourly the longer the threshold stays crossed, and hovering over them only scares them away temporarily rather than clearing the underlying trigger.
The site doesn't present it as part of a bundle — it points to Hidden Bar as a separate, third-party companion for concealing menubar icons, rather than an in-house suite of its own.
The reviewed page includes a purchase link but doesn't state a price directly, so exact cost isn't confirmed from the page alone.
