[Solved] Asus Maximus VII Impact - slow boot HID: Legacy shim 2

[gulios]

ok, i found that it can be TRIM(APFS) issue and it was that.
I've disabled TRIM

sudo trimforce disable

and `HID: Legacy shim 2` disappeared. Boot time takes ~10s

so now it's fine but i'm thinking is it good to have TRIM disabled...?

Having both APFS & TRIM is not a good idea. If you want to carry on using TRIM then use HFS+. Better to use Clover's TRIM KextToPatch than Apples TrimForce.

                <string>IOAHCIBlockStorage</string>
                <key>Find</key>
                <data>
                AEFQUExFIFNTRAA=

                <key>Replace</key>
                <data>
                AAAAAAAAAAAAAAA=
                </data>
                <key>Comment</key>
                <string>TRIM Enabler</string>
            </dict>

and of course again slow boot because of "HID: Legacy shim 2"

Do you have some URL with details describes why is not good idea to have TRIM on APFS?

Thx

Should be disabled with APFS. You can disable it instead of deleting it from the config.

By doing a clean install in HFS+ and disabling the automatic conversion to APFS in installing process by using @RehabMan guide found here.
The boot time now are much better 8 second with my 960 pro NVME drive.
HID: Legacy shim 2 latency completely gone from the booting log.

for now TRIM is disabled with APFS and everything works fine without boot errors.

so after few weeks in 10.13 with APFS and TRIM disabled everything works fine. Boot time <10s, great.

we can mark it as [SOLVED]

How do I type that in my config.plist?
I'm kind of new into clover and I'm getting confused with <key><data> parts.
I could not disable TRIM because of that.
