When a file won’t open, save, move, or delete, the block is usually somewhere around it. File First Aid checks each layer in order, stops at the one that’s failing, and shows its work.
Free to diagnose · one-time to fix · macOS 15+“Q2-report.pdf” is readable, but saving changes means writing a replacement into “1 Save blocked by folder”, and your account doesn’t have write access to that folder. That’s why the save fails even though the file itself opens.
A writable copy now exists at ~/Documents/Q2-report.pdf. The original is unchanged.
The line sits where the risk does. Reading what’s wrong is free. Changing something is the paid step, and you approve it first.
Tell it what you were trying to do. It checks each layer, stops at the one that's failing, and explains the cause in plain language. Run it as often as you like; there's no trial clock.
Before anything changes, you see the precise action it will take, and everything it won’t touch. No surprises, no permissions dump.
One click. The original is left untouched, the result is verified, and you can undo it. This is the only step you pay for.
The diagnosis is free every time, forever. You pay once, when you want the fix applied.
No permission bits, no metadata dump. Just the finding, how sure it is, what it didn’t check, and the exact edge of what a fix will touch.
“Q2-report.pdf” is readable, but saving changes means writing a replacement into its folder, “Client Uploads,” and your account doesn’t have write access there. That’s why the save fails even though the file itself opens.
Cause first, in a sentence you can act on, not an error code to go look up.
Stated up front. A guess is labeled a guess, never dressed up as a fact.
The greyed line is a check it didn’t run, said out loud instead of hidden.
Exactly what a fix will touch, and what it deliberately leaves alone.
You tell it what you were trying to do. That choice decides which layers even get tested.
The forum advice you were about to try, and why this doesn’t.
No subscription. No trial that expires while you’re not looking. One price, and you own it.
No. It never deletes, overwrites, force-quits, or bypasses macOS security. Every fix is reversible or non-destructive, and the file’s contents are never changed.
If your Mac is on macOS 15 (Sequoia) or later, yes. File First Aid is a universal app that runs natively on both Apple silicon and Intel Macs — one download, no Rosetta, nothing to choose.
Yes. It’s signed with a Developer ID and notarized by Apple, so Gatekeeper trusts it — no “unidentified developer” warning to click through. It runs with Apple’s hardened runtime, installs no kernel extensions, and never asks for your admin password or Full Disk Access. You download it directly as a notarized DMG, not through the App Store.
It says so plainly, points at the app or cloud provider responsible, and hands you a redacted report to forward instead of guessing.
No. Everything runs on your Mac, offline. No account, no cloud upload, no reading of your document’s contents.
Yes — it keeps working, forever. It’s a one-time purchase, not a subscription, so the app you bought never stops or expires. Your purchase includes a year of updates as macOS changes; after that, it keeps running exactly as before. If you want another year of updates, you can renew at a discount, but that’s always optional — nothing you’ve paid for is ever held hostage.
See exactly what’s wrong in seconds. Pay once, only when you’re ready to fix it.
