Although macOS does monitor the condition of internal storage using SMART status indicators, the most information it gives about this is in Disk Utility, where it simply reports the disk status as ‘verified’, which is of no help in assessing SSD wear.
There are two ways to estimate wear in an SSD. One is to check the disk’s SMART health indicators such as Life Percentage Used, which should be available for all recent Apple internal SSDs. The other is to work out what proportion of its life has been used according to the amount of data written to the drive. For either of these you’ll need a third-party app such as DriveDx from bit.ly/ml195drivedx.
