@AliKelman. Welcome to the Forum. I am sorry to be the first to reply to you as I do not use Mac, so cannot give you much help myself. I suspect Mac converts to Zorin may be in the mirority here, so you may have to search Ubuntu and other Linux forums to find similar installation questions for MacMini.
I did find this one item on the old Zorin Forum, which may or may not help you.

I assume from your last screenshot that you have stopped at the point of running Zorin Lite from USB and have not proceeded to install.
Is it true you have created a EXT4 partition on your SSD. I think you need a non-journaling FS for a SSD. I expect others here will advise on that. (Edit: Format EXT2 to save wear to your SSD)
Also. Have a look at Swarfendor's unofficial Zorin 15 Manual here:
