Uh, oh, you could be in a heap o' trouble.
Is there any way you can GET BACK your old Mac?
If not, do you know anyone that has an older Mac, about the same age as your previous one?
It looks like you may need to do something like this:
1. Find an older Mac that will still mount the t5.
2. Get ANOTHER HARD DRIVE (yes, I said another one) the same size.
3. Use DISK UTILITY to format the
new hard drive to Mac OS extended with journaling enabled, GUID partition format.
DO NOT DO NOT DO NOT
... encrypt this drive!
4. Download CarbonCopyCloner (CCC is FREE to download and use for 30 days) from:
www.bombich.com
5. Use CCC to copy the contents of the t5 to the second hard drive.
6. Take the second hard drive to your NEW Mac and see if it will mount now.
7. If it does, either use Migration Assistant to migrate your stuff, or else move it manually (other special considerations may be required).
THAT'S what you're probably gonna have to do.
Once you get your stuff onto the new Mac, I suggest you REMOVE ALL the Samsung software from the t5 -- that is, erase it completely and start over.
And again,
DO NOT use encryption.
You see where having used it has "gotten you to" now!
Just wondering... is there a brick n mortar Apple Store anywhere near?
Perhaps the genius bar could assist you in doing the migration...
