Lost space after a failed windows10 installation

Hello and good day,

TL;DR is there a simpler fix to regain lost space from a failed windows installation rather than backing up and reinstalling macOS?

Regain Space after Deleting Windows I just deleted Windows from my MacBook Pro using the Bootcamp Assistant. My computer still says I have only 200 GB of total storage when I should have 250 (the Windows partition was 50 GB). Is there any way to fix this without reformatting the entire drive and reinstalling macOS? Thanks!

How to recover 70GB I lost after removing Windows 10 I had a Windows 10 install in a partition of 70GB. I removed it through boot camp assistant but now I have list the 70GB, how can I restore it? My disk is 500GB but the space in macOS is listed as 430GB so the 70GB is lost, as you can see here: This is the output from diskutil list The Microsoft Basic Data GPU 30.4 MB disk0s3 is a small bootable disk because I am trying to get an eGPU working. FYI. Some other output from commands I've seen requested: diskutil cs list No CoreStorage logical volume groups found sudo fdisk /dev/disk0 sudo gpt -vv -r show /dev/disk0 And here's how my storage info looks for good measure: And my device: I will try to provide any info more that is needed. I am forever grateful if someone can help me deal with this.

Backing up and no mention of partitions being resized, it probably means I'll atleast get my 1,8tb, wooohoo

but to do these steps described to re-create fusion drive, I would need to erase underlying disks, am I right? Not sure I fully understand, language barrier.

Yes, you need to erase both underlying 'full' disks, and rebuild the Fusion drive from scratch.
