Apple’s Trim driver is closed source, so it’s hard to know for sure. But it is believed that Trim on OS X is not using this new queued Trim implementation (that causes corruption on Linux), and that the “trimforce warning message” is instead referring to very early Sandforce SSD’s (from the beginning of Trim in OS X, around 2008-2009). These drives did have notable issues when using Trim in OS X, for example boot or emptying trash taking forever (>3 minutes). Just speculations at this point.
