How to Force Enable TRIM in macOS

A Trim command which allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally.Trim was introduced soon after SSD’s started to become an affordable alternative to traditional hard disks. Because low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSD’s


In other words TRIM helps to maintain the performance of solid state drives (SSDs) at an optimal level over the lifetime of the drive. TRIM functions by actively deleting invalid data from the SSD’s memory cells to ensure that write operations perform at full speed.
