hello! i just cloned my a1278 to a larger SSD. now, how do i claim that extra space? i'm hoping for a youtube link?

THANKS!!!!!
 
Just use it? I must be missing something. You've cloned your smaller SSD to a larger one, right? So you just start up your MBP as usual and now you have more room for photos, documents, videos, music, etc.
 
Hello and thank all of you SO MUCH to take the time to reply. In trying to be brief, I left out a good portion of my issue. Here is how it all happened. I used one of those "toaster" hard drive reading units to clone a 750GB hdd to a 1TB drive. It went off without a hitch, but it did not incorporate the extra 250GB on the new SSD. I then tried using disk utility to open up that 250gb, but as you can see by the attached image, the mac kept failing.

I tried using the utility by using command r, as well as on the booted up OS and got the same error--

"the new size must be different than the existing size, (-69743)"

You know how macs are sometimes fickle...i'll never forget the first time i ran into not being able to download a new OS because the device's time was off compared to Apple's servers!

Should i try a different way to clone the SSD?

So are you saying the cloning process created a 750GB partition and left he rest of the space unparitioned? And in your post above you're trying to create a partition for that 250GB and it failed?
 
yes, you stated it perfectly. i need to get the OS to recognize that unused space.
 
It sounds like you went and made a second partition, named it "free space", and now you don't understand why you can't grow the 750GB partition into it. But you don't need two partitions, just remove the second partition and grow the 750GB partition to 1TB. It shouldn't be more complicated than that
 
that's what i thought, but when i clicked on the open 250GB, the "+" option is dimmed, i can only hit the "-" choice, then i get the screen i posted. it looks like i'll have to re-clone the old drive using mac software or maybe use the time machine option?
 
OP:

Trying to understand just what you did here.

Are you saying you used one of those "2-bay" automatic cloning docks?
Did you take the factory drive out of the Mac, and put it into the cloning dock along with a fresh SSD?
I don't think that will work right.

THE RIGHT WAY TO DO IT:
1. Have the original drive IN the Mac.
2. Get an external dock (1 bay, NOT "a cloning dock), or enclosure (for temporary use).
3. Put your NEW drive into the dock or enclosure.
4. Download CarbonCopyCloner from:
Carbon Copy Cloner - Download
CCC is FREE to download and use for 30 days -- this will cost you nothing.
5. ERASE the SSD/target drive using disk utility.
6. IMPORTANT: if you're using Mojave or later, you MUST go to the VIEW MENU and choose "SHOW ALL DEVICES" so you can see all the drives and volumes.
7. Again, erase to APFS with GUID partition format
8. Quit disk utility and open CCC
9. Set the original drive as the source and the SSD/new drive as the target.
10. You haven't told us WHICH OS you are using. If it's Big Sur, I think you have to choose "legacy clone" in CCC's preferences in order to create a bootable clone. This can be tricky, but it seems to work for others.
11. Create the clone.
12. When done, DO A TEST BOOT. If it's an Intel Mac, hold down the option key at boot continuously until the startup manager appears. If it's an m1, press and hold the power-on key until the options appear.
13. Assuming you get a good test boot, now's the time to open the Mac and install the new drive.
