Questions

Will it erase my files?

No. Veracard writes only to the card's free space and deletes its test files when it's done. If a card is too full to test, it asks before anything is erased, and it never formats a card unless you ask it to.

What can it check?

SD and microSD cards (with an adapter or a card reader), USB flash drives and external SSDs. The chip details in the X-ray need the Mac's own SD slot; with a USB reader you still get everything else.

How long does it take?

The quick check takes a few minutes on a good card. The optional advanced test reads and writes every free byte and can take hours on a big card. You can stop at any time and keep the best answer so far.

Which Macs does it run on?

Any Mac with macOS 14 Sonoma or later, Apple silicon or Intel.

App Store or directly from you: what's the difference?

It's the same app. Bought from us, it does a little more, asks for fewer permissions, covers up to 5 Macs and updates itself. See the comparison.

Does it collect data about me?

No. There are no accounts, analytics or ads. Results stay on your Mac. Sharing with the Community is optional and never includes anything about you. See the privacy notice.
