Recovered files from a corrupted APFS partition
The APFS partition corrupted leaving data on the external SSD with no way to access it. "Checking the space manager. error: spaceman cib out of order: 47, expected 69 Space manger is invalid" After doing my research, YouTube, Tech Radar etc, I found CleverFiles and Disk Drill. I also found the Disk Drill on the Mac App Store. I downloaded the file and scanned the disk. It found everything. I was able to recover 1.5TB in 3 hours.
