Can you still use OS X Yosemite?
Upgrading prematurely may result in a potential loss of data and performance as a result of incompatible applications. As a result, we are phasing out software support for all computers running macOS 10.10 Yosemite and will end support on December 31, 2019.

Why is Disk Utility not working on my Mac?
If Disk Utility can’t see your disk, it also can’t see any containers or volumes on that disk. In that case, follow these steps: Shut down your Mac, then unplug all nonessential devices from your Mac. If you’re repairing an external drive, make sure that it’s connected directly to your Mac using a cable that you know is good.
What to do when there is no disk on your Mac?

Why is Disk Utility not showing partitioning options?
I cannot believe I am the only one having this problem in the whole wide world. It’s not a bug. Disk Utility still offers this option but only if you choose ‘Wipe’ on physical device rather than volume (which makes perfect sense). In 10.13 Apple has simplified Disk Utility’s view so it only shows volumes (omitting physical devices).
Where do I find the Disk Utility on my Mac?
Choose View > Show All Devices (if available) from the menu bar or toolbar in Disk Utility. The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. And beneath each disk you should see any containers and volumes on that disk.
