Boot Partition doesn't have the correct storage space So my SSD has 500 GB of storage I have only one Partition (the Macintosh HD Partition) but it only has ~100 GB storage space.



Is there any way I can get my total ~500 GB of storage on my partition?

here is what shows up in terminal (command diskutil list)
You probably had some dual boot config previously and removed the main Windows partition(s). You didn't expand the APFS container disk0s2 afterwards.

A small blocking disk0s3 is a left-over though (right "after" disk0s2). This small partition has to be removed before you can expand your APFS container.


Erase the Microsoft Reserved partition:

diskutil eraseVolume "Free Space" %noformat% /dev/disk0s3

Expand the APFS container:

diskutil apfs resizeContainer /dev/disk0s2 0
