my ssd is 481 gb but mac os give me 151 gb

hi, i wanted to clone my macbook hard disk to an ssd, so i take out the hard disk and i connected the ssd and the hard disk in my windows computer to clone the hard disk to ssd. So i used macrium reflect that it worked very well and it can read mac os hard drive. But there is a problem, the ssd that im using now is 481 gb but mac os think that is 151 gb (the dimention of the hard disk), i cannot make the partition more bigger with utility disk. How i can do it?

Perhaps the partition maps are incorrect across the different systems OS?

Depending on what you actually have there, an HFS+ or APFS (for Mac)

the Windows OS might not do well at all for those. And newer macOS

could use more than you think ~ once it starts creating extra partitions.

I'd not proceed without more information; and an alternative plan.

That's just me; when something doesn't sound good to go, I won't.

[Oh, there are two mac-centric clone utilities, these run in demo-mode

(or did, last used here) 1. SuperDuper and 2. Carbon Copy Cloner.]

Are the two drives the same size, for example both 500GB? If sizes are different you may get unintended results depending on the cloning software and how it handles different size drives. I cloned a 500GB drive to a 1tb drive and I ended up with a good 500GB clone alright, but also 500GB of unallocated space.
