我决定根据以下建议为我的 SSD 启用 TRIM：这个 SU 答案。
出现了一些错误，我无法启动，最终不得不从 Time Machine 恢复。
编辑：
我手动替换了二进制文件
IOAHCIFamily.kext/内容/插件/IOAHCIBlockStorage.kext/内容/MacOS/IOAHCIBlockStorage
其中之一已被编辑并修复了权限。 我错过了关于第一次启动可能需要很长时间的部分（机器的正常启动时间是 8 秒） 我只花了几分钟并尝试重新启动了几次。
我尝试通过终端恢复我对二进制文件的备份来手动修复它，但仍然无法启动。
在恢复并重置 PRAM、验证磁盘和修复权限后，我也成功启用了 TRIM。
第二次我只是使用了Trim Support Enabler
现在我遇到了弹窗和短暂冻结。这通常发生在 Chrome 中，但也发生在 TextMate 中。我以前没有遇到过这些问题。
我如何确定问题是源于启用 TRIM 还是源于 Time Machine 还原？
这是几分钟前刚刚发生错误时的错误日志。

答案1
导致问题的原因是启用了 TRIM。我从备份中恢复了内核扩展，所有问题立即消失。
为了确保这不是侥幸，我遵循了所有步骤并重新启用了 TRIM，但问题又出现了。
结论：不要破解内核来为不需要 TRIM 的驱动器启用 TRIM。
答案2
您应该做的第一件事是使用磁盘工具验证磁盘，并在必要时修复磁盘。
