Pros:
✅ Resizes/moves partitions without data loss
✅ Supports APFS, HFS+, exFAT, FAT32, NTFS
✅ Clean, visual interface (better than Disk Utility)

✅ One-time purchase, no subscription
✅ Works on Intel and Apple Silicon (M1/M2/M3)

Cons:
❌ Cannot relocate non-adjacent partitions
❌ No dark mode, dated UI
❌ NTFS write support is absent (you can format to NTFS but not write to existing NTFS volumes)
❌ Free trial is read-only — you can’t test actual partition changes
❌ Slow on large spinning HDDs (but that’s physics)
