6 Signs Your MacBook's SSD Is About to Fail
Random freezes or kernel panics Your MacBook freezes or crashes unexpectedly, especially when reading or writing files.
Frequent app crashes Applications hang or crash for no obvious reason.
Corrupted or unopenable files Files become corrupted or refuse to open.
Slower boot times Startup goes from fast to painfully slow.
S.M.A.R.T. status says “failing” If Disk Utility shows “S.M.A.R.T. status: failing,” the drive is on a countdown to failure.
No backup in place If you haven’t set up Time Machine to an external drive or a cloud backup like Backblaze, you will lose everything when the SSD dies. Run a backup now.
