trimforce probably makes a drive system level call, to 'enable TRIM' on the drive. Using a third party tool such as "Disk Sensei" would probably NOT add anything to that process. At most, all it can do is make that same drive system level call that trimforce is already making. In other words, if it doesn't work properly using trimforce, it won't work any better with any other tool.


The one benefit of "Disk Sensei" is that you can enable TRIM via a GUI interface and see the current TRIM status via that same GUI interface.


To view the current TRIM status for your drive via GUI interface without using any third party tools,

navigate to 'About this Mac' -> 'System Report' -> 'SATA/SATA Express' and look in the details for: 'TRIM support'
