Clones 240 GB SSD to 525 GB SSD - Expand Partition

[fenderbass146]

So I have a 2013 iMac (RIP due to no more updates because Apple sucks, but that's beside the point) and due to it being such a pain to install a SSD on the inside I am just running my OS on an external SSD. Well the SSD failed/is failing so using a cloning station (the kind you put two hard drives in and hit clone) I migrated my whole SSD over to the larger SSD. The thing worked great. Speeds and responsiveness of the new hdd are immediately better, however, the partitions did not expand. Also, with disc utility I can't expand them as I used too. How do I go about using all the space on my new SSD or am I better off doing a fresh install...

I'm formatted as AFPS but I get an error every time I try to use that extra space.

I found the answer

How do you INCREASE the size of an APFS volume?

I've created an APFS volume on a MBP running High Sierra in order to use it as a Time Machine drive for the iMac I use at work (we don't have a backup solution so this is my hacky way to keep mysel...

Easy way: Carbon Copy Cloner or Superduper

OP:

If you haven't resolved the problem by now...
I sense the "cloning station" had a lot to do with it.

What you need to do is this:
1. Mount the source drive (240gb) on the Mac. DO NOT USE the cloning station, or use only "one side" of it (to mount the drive on the desktop).
2. Mount the target drive (525gb) on the Mac. Again, DO NOT USE the cloning station. Use another drive enclosure. You want TWO SEPARATE enclosures for this procedure.
3. Download CarbonCopyCloner from here:

Download CCC - Bombich Software

www.bombich.com

CCC is FREE to download and use for 30 days -- this will cost you nothing.
4. Make sure your target drive is freshly-erased so that all 525gb are available.
6. Now use CCC to clone the source drive to the target. Accept all of CCC's default settings. CCC may also ask if you want to clone the recovery partition. YES, you want to do this too.

CCC will clone over the source to the target, but the finished (cloned) target will still be a 525gb drive. There will just be "more free space" on it.

Thanks it was my first time using a cloner on a mac. It's always worked flawless on Windows boxes. (I work for a managed IT company). After I found the command I was looking for i was able to expand it and my machine is working great again.
