Restoration Small SDD

[Odroid13]

First of all I wanted to thank you for your distribution ^^

However, I can't find a distraction that resolves a persistent problem :s

Let me explain, I am a Hackintosh user, I installed OSX on a 512GB SSD with 3 partitions:
1 EFI
2 OSX
3 EMPTY

I manage to make a backup in the EFI & System OSX partition and it works perfectly.
In my backup there is no 3rd partition because it is too big and is of no use to me since it is an empty space.

The problem I'm having and I want to restore the backup to a 250G SSD, so it's smaller.

Normally there should be no restoration problem because the partition backs up its EFI & System OSX (40GB)

When restoring it tells me that the disk is too small, I don't understand?

Do you have a solution

Thanks

ps: If I do a restoration on the source disc it works
