Has anyone managed to create a bootable macOS Sierra installation on a partition from Samsung T3?

For some reason, when I press Alt on bootup, it does not show the installation partition which I created with Diskmaker X.

My partitions on this drive goes like this:

  1. T3 (For media files)
  2. Mac Apps
  3. Bootable macOS Sierra Installation

Yes, it was rather easy, and I'm running on one now.

I booted up in recovery mode, selected the SSD, partitioned/formatted and then installed OS X.

try and skip these 3rd party utilities for making bootable macOS installers - macOS Sierra and down to Mavericks there's a included "createinstallmedia" command for you to use. Apple Support has the lowdown here:
https://support.apple.com/en-us/HT201372

If you format your USB key for macOS then name it "MyVolume" as according to the string on the support page from Apple.

Else, follow the suggestion from @maflynn above for getting macOS onto your Samsung T3 - which I also have to now check out once more just because I feel left behind on SSD technologies.

Did you partition your drive in GUID or Master Boot Record?

I will also try to create a bootable partition with the official way from Apple Support instead of Diskmaker X. Will keep you guys posted...

Currently my Samsung T3 is not bootable. I might have done something wrong when partitioning the drive.

Not fully clear on what you mean yet. Do you mean installer like a partition that can be used to install Sierra to other machines, or installation as in a fully functional volume that boots into the Mac OS user environment?

If the former, your best bet is to follow the official apple directions that allan.nyholm posted. I have done this on a T3, the 1TB model and it worked fine. If the latter, you can use a recovery partition to install the OS to a partition. Either way to be bootable on a Mac you must use GUID partition scheme.

Ok thanks for the info. I meant a partition that can be used to install Sierra to other machines. Will give this a go as soon as I finish downloading another Sierra installation.

On a side note, I have also enabled Samsung security activation on my T3. Not sure if that matters as far as bootable goes? I have also tried disabling my password as well, but in vain.

Will keep you guys posted.

In my opinion, a FAR better way to do this would be to create a bootable installer on a USB3 flashdrive (16gb or larger).

Use that where needed....

I managed to make it work by creating a bootable installation using the official Apple support method (terminal).

Thanks a lot to everyone!
