How to get help
For questions, bug reports or feature requests about any Apis Systems application, email us at [email protected]. We reply within one to two business days.
To help us resolve your issue faster, please include the application name, its version, your macOS version, and a short description of what happened.
Disk Reviewer (macOS)
Disk Reviewer is a local disk cleanup tool for Mac. Answers to the most common questions:
Is any of my data uploaded anywhere?
Not the part that matters: file names, paths, sizes and everything a scan finds stay on your Mac. The app does send anonymous counters of which features are used — never what they found — and you can switch those off in Settings. It also sends a feedback report if you write one and press Send. Nothing else leaves your device. See our Privacy Policy for details.
How do I report a problem?
Open Disk Reviewer and choose Feedback in the sidebar, under Settings. Describe what happened, attach a screenshot or a screen recording if it helps, and send it — the report reaches the person who builds the app. Leave the diagnostic log attached if you can: it holds the last week of app events and errors, and it cannot contain file names, paths or scan results. Add your email only if you would like a reply. You can also write to [email protected].
Where do deleted files go?
Files you remove are moved to the macOS Trash, and photos are moved to the Recently Deleted album in Photos. Nothing is erased permanently by the app, and nothing is removed without your explicit confirmation.
How do I restore a file I removed by mistake?
Open the Trash, right click the file and choose Put Back. For photos, open Photos, go to Recently Deleted and choose Recover.
Why can't the app see some of my folders?
Disk Reviewer runs in the macOS sandbox and can only read locations you grant access to. If a folder is missing from results, add it again and approve the system permission prompt.
DeckMirror (macOS)
DeckMirror shows the screen of an iPhone or iPad connected by cable in an ordinary Mac window, ready to share in a call.
Nothing appears when I connect my device
Three things have to be true: the device is connected with a data cable (some charging cables carry power only), it is unlocked, and you have tapped “Trust This Computer” on it. On recent versions of iOS the device also asks “Allow accessory to connect?” — tap Allow. If the device still does not appear, unplug it and plug it back in with the screen unlocked.
Why does it ask for camera access?
Because macOS delivers the screen of a connected device as a capture device, the same way QuickTime Player receives it for “New Movie Recording”. That permission is the only way to read it. DeckMirror never uses your Mac’s camera and never opens one.
How do I share the window in Zoom, Meet or Teams?
Share it as a window, not a screen: in the conferencing app choose the window called DeckMirror. The toolbar stays at the top of the window and the device’s picture sits below it, so the bar never covers the phone’s own screen.
Does it record anything?
No. Nothing is recorded, and the mirroring path has no network access at all — the picture goes from the cable to your screen and nowhere else. Two other things can leave your Mac, both yours to control: anonymous counters of which features are used, which Settings can turn off, and a feedback report if you write one. If you want a recording, use any screen recorder on the window — it is an ordinary window.
Can I mirror over Wi-Fi?
No. DeckMirror is cable only, by design: that is what makes “no network path at all” true rather than a promise.
Does it work with an iPad?
Yes. Any iPhone or iPad that connects to your Mac by cable works, and the window takes the shape of whichever device is attached.
How do I report a problem?
Write to [email protected] with your macOS version, the device model and iOS version, and what happened.
