Slow boot due to Samsung SSD TRIM on macOS Monterey about hackintosh

[shiruken]

SetApfsTrimTimeout seems to have no effect on boot times, possibly indicating that long boot times are not being caused by the problematic Samsung SSD TRIM operation. Boot time measured from motherboard logo to macOS login screen. Used authorized restart to bypass FileVault 2 login.

SetApfsTrimTimeout	Boot 1	Boot 2	Boot 3
-1	2:55	2:55	2:55
999	2:54	2:55	2:55
4294967295	2:53	2:56	2:54

Just to be safe, updated configuration such that SetApfsTrimTimeout=4294967295 (2cf0bfd). While this won't resolve slow booting, it will guarantee the TRIM operation completes.

I am using 980Pro and I have the same issue. SetApfsTrimTimeout settings won't affect the long boot time.

FWIW, I shifted my install from a Samsung 970 EVO to WD Black drive for this very reason. Continuing to use the Samsung for additional storage.

Per OpenCore 0.7.9:

On macOS 12+, it is no longer possible to set trim timeout for APFS filesystems. However, trim can be disabled when the timeout value is set to 0.

Setting SetApfsTrimTimeout=0 (0c33c56) now results in system boot of less than 10 seconds. This "fix" is less than ideal and will lead to ever increasing performance degradation on the SSD. Occasionally booting with SetApfsTrimTimeout=-1 should theoretically help alleviate this risk.

I will continue to monitor the Dortania bugtracker discussion about this problem.
