McSync
For the Mac

Nothing gets
lost.
And you watch it happen.

Twenty years of photos sit on a single disk. McSync puts them down a second time — on the external SSD, on the NAS, wherever you like. Drag a folder in, draw a line, let go. No expertise required.

Dead simple

If you can drag a folder,
you can use McSync.

No wizards, no command line, no jargon. Three moves, and it runs.

Drag a folder in

From the Finder onto the surface. It sits there as a tile with a name and a colour — and you can tell at a glance which one it is.

Draw a line

From one tile to another. The line is the instruction: “take this over there.” As many lines as you need.

Let go

One click, and McSync tells you first what it would do. Nothing moves a single file until you say yes.

Your pictures

A disk doesn't last forever.
Your photos should.

Hard drives fail, usually without warning. The only thing that helps is a second copy — and it has to be current, otherwise it is just an old promise.

  • New pictures are added without overwriting what is already there.
  • At the destination a file is either fully there or not at all — never half.
  • Whatever should go lands in the Trash, not in nowhere.
  • And weeks later, when the question comes: the log says what happened.

One more thing, openly said: a sync is not a backup, and we accept no liability for lost data. Keep a real backup as well — that holds for any tool of this kind. More in the terms of use.

Watch it

Copying you actually enjoy watching.

Not a bar that sits still for ten minutes and tells you nothing. You see which file is running, how fast it goes and what is still to come.

  • For a big file, a second bar runs just for that one.
  • Every finished file gets its tick — you see the work grow.
  • While something is running, your Mac stays awake.
  • A notification at the end, even when you have long moved on.
Connect

One board. As many routes
as you need.

Laptop, external SSD, NAS, the archive in the basement: every place is a tile, and you connect them however suits you. Each line has its own job — one keeps two folders equal, another only fills up.

One look tells you where you stand

After checking, the line takes on a colour. That is all you need to read:

  • All equal
  • Differences
  • Have a look
  • Several boards: one for home, one for the office, one per client.
  • Every tile can tell you how much lies in it.
  • Related places can be grouped and moved together.

Keep them equal

Both sides on the same state — one way or both ways.

Only fill up

What is missing is added. What exists stays untouched. The harmless choice.

No knot in your stomach

Nothing happens behind your back.

A program that can delete files owes you an explanation before it does.

Show first, then act

Beforehand it says what will happen — counted out. Only then may it run.

Trash, not gone

Deleted files sit in your Mac's Trash. That is where you get them back.

Undo

Mis-clicked? The previous state is one move away.

All on record

Every run is written down: when, how long, which file.

Stays with you

No cloud, no account, no server. McSync is not even allowed online.

A real Mac app

Windows, keyboard shortcuts, dark mode — all where you expect them.

Price

Starting costs nothing.
