I know this has been addressed before but...
Trying to Partition a newly purchased Samsung T5 SSD as boot and external drive.
Partition is grayed out in Disc Utility.
Anyone have a solution as to how I can partition this new SSD.?
Thanks.
iMac 27", macOS 10.14
Plug your T5 in. Open Disk Utility. Go to the upper left of the Disk Utility window. Click on "View". Select "Show All Devices". Go to your "Samsung Portable SSD T5 Media" in the sidebar. Click on it. Select "Erase" in the top toolbar. Now select your Format: select APFS or Mac Extended (Journaled). Click on Scheme: choose GUID Partition Map. Click on "Erase" at the bottom right. Wait until Disk Utility finishes up. If you wish to make more partitions on your T5 click on "Partition".

Hi again,
This is another question, quite naive I admit.
Even though , with your help, I succeeded in re-formatting the T5 SSD into extended journal and GUID......
Here is the next question-
Do I actually have to physically create a partition for mac OS only and another separate partition for the Applications/files/photos/music, etc?
Thanks again,

Thanks very much.
Currently transferring apps/files/photos to my new external Samsung T5 SSD (Boot and Main Drive).
You have been a wonderful help. Thanks for giving your time and sharing your knowledge.

BTW - T5 SSD is FAST
Nope.
Please read Partition a physical disk using Disk Utility on Mac:
"How you partition a disk depends on the file format it uses."
Thank you both for your prompt replies.
It seems as though the suggestions/recommendations have worked.
I'll let you know if I succeed in creating an external SSD macOS Boot and Primary drive.

Following up on above discussion about moving iMac internal HD to external Samsung T5 SSD.
It has been performing flawlessly so far.
Fast.
Like a new iMac!
Thanks again.
