Cloning SD card

I have a working sd card that I wish to clone into another so that I can re use the current working one.

I use a Mac but I also have Windows 7 available to me, running inside a virtual machine on the Mac.

I've tried using the disk utility in the Mac, creating an image of the current working sd card, then I take this image a copy it to the new sd card using Etcher.

However, when I insert this new sd card onto the pi, it won't work.

By "not working" I mean that when I use PuTTY to communicate with the pi, it won't see it.

Does anyone here have tried this and found a working way to clone/duplicate an sd card?

 

win32disk imager downloaded as an .src file. Unzipped it but, except for the Unix executable, there's nothing there for me to run, as in an ".exe" file.
I clicked on the Unix executable file, a terminal window opened on my Mac, some scrolling text and that was it. Nothing I could make sense of.

 

Yeah, that's another thing, every time I Google win32disk imager, the main result takes you to a page where the download comes in the form of a .src file.

I did try using the disk utility in Mac. It seemed to work because it did duplicate the exact contents of the working sd card, however, when I put the duplicate on the pi, it won't do anything.
The screenshot below shows the contents of both cards.
The image on the left is the cloned card.
The image on the right, is the original card.
As you can see, they're exact, but the one on the left, does nothing in the pi.

 

I also have ApplePi but I don't have an sd card of the same size as the one that I want to clone. ApplePi requires that cloned cards be the same size as original.

 

Maybe the issue isn't the SD card as for itself, but about software/method used.
The Raspi SD card contains two partitions.
Usually the imaging softwares (etcher, win32diskimager, etc) don't care about the logic structure
of the media they're copying, they simply replicate what they find, one or more partitions it is the same for them.
But a disk utility could behave different (sorry, i don't know the Mac utility, never had a Mac before),
maybe the software expects to find one partition only.
If that is the case, the cloned SD card might be uncomplete.

 

Ok, I found the Windows download for win32diskimager.

Placed the sd card I want to copy, launched win32diskimager and navigated to where the sd card is.

But, win32diskimager is looking for an image? When I click on where the sd card is, there's 2 images named kernel and kernel7, don't know which to choose.

 

Yes, but which image?
As you can see above, "boot" is the card I want to clone.
When I launch win32diskimager and navigate/select "boot", there's two folders and two disc images (didn't knew kernels were images).
And, even if I were to guess/choose one of the kernels, what about the folders; ".fseventsd" and "overlays"?
Are they needed?

 

Yes, I'd think you can see for yourself. Go ahead.

 

Got Zerotier installed.

 

Where is my login info?
I installed zerotier, got a node ID?

 

PC, took out the sd card to try and clone it.
