Q: How do I check my Mac SSD's health?

For a basic check, open System Information (hold Option and choose Apple menu → System Information), select NVMExpress or SATA, and look at S.M.A.R.T. status. "Verified" means the drive reports no problems. Disk Utility also shows S.M.A.R.T. status for some drives. Detailed wear figures need third-party tools. Whatever the status, keep a backup — drives can fail without warning.

Short answer: Open System Information, choose NVMExpress or SATA, and check S.M.A.R.T. status; Verified means no reported problems. Keep a backup regardless.
