    external ssd will not partition, can create no recovery drive for sierria (using carbon copy cloner) to create boot drive on imac late 2015... utilities partition greyed out on both imac and lap top even after reformating. says t5 partition scheme incompatible with mac osx intel.....any work arounds ????

    I've not got a workaround sorry, but can confirm that I've partitioned T5 drives in the past so it's not an issue with the Samsung architecture.

    Hope you find a solution soon as they are great drives - very fast and reliable in my experience.

    Make sure you're using the "GUID" partitioning scheme and not any other. The T5 should partition just like any other drive.

    Are you actually trying to use Disk Utility.app to create the partition?

    And are you selecting the name of the drive, and not any volume named below the main Drive name?

    As far as I know, the "GUID" partitioning scheme shouldn't matter or be required on an external drive.

    have imac w/ 2 externals, back up and ssd boot, boot is failing,( disk warrior cant replace directory due to damaged drive ) ....got T5 to replace imac external but when copied, drop down stated that the partition scheme was not compatible with apple intel osx and im left with data storage not a boot. im thinking repartition T5 but utilities is not allowing it, the only thing i could do was erase and reformat the T5 which was done twice..... perhaps due to Samsungs T5 versatile applications the architecture is storage only with the apple osx....
    either samsung is hiding the fact or im missing something .....

    How did you copy to the T5? What app provided the error message? How did you erase and reformat the T5? There is, AFAIK, no reason that SSD should not work as an external bootable if formatted properly.

    Maybe have a read here and give it another try:

    Make sure the selection option you want is showing and not hidden.

    It sure does if you expect to boot with it. The way I read his post, is that's exactly what he's trying to do.

    you are correct .....was not enabling guid on format ......have done so and recovery volume is now installed in T5 boot drive

    Thank you all:

    Congratulations!!!
    Don't ask me why, if this was your case, and as a warning to others, Apple for some reason makes doing so harder than necessary:
    Disk Utility in macOS High Sierra doesn’t make that option easy to find. Read on to see where it’s hiding.
    ... Disk Utility hides the GUID format option by default

    Patrick, that article was more than just a bit hyperbolic. The GUID option is right where it's been for 4-5 versions, at least, of the OS. Not "hidden" and not particularly hard to find. Under "Erase," which is where, logically, it needs to be.

    Just relaying what a user's experience found Jake, and I dare say they were not the only one who found the operation a bit more difficult than it should have been.

    I'd say something is sure not as good as it could be considering of the number of times the formatting question gets asked in various Mac forums.

    Anyway, the OP finally got everything working the way they need I gather, so that's good.
