Hello, I want to open this thread to get the latest news about the new SMBios iMacs 2019 and the compatibility with 9th Gen Core Coffee Lake CPUs (i5 and i9).
Update 2: Clover Configurator 5.4.2.0 is out, add SMBios for iMac 19,1 and 19,2 :headbang:
Update 1: (Info get from bootmacos ) Sorry for my English

iMac Early 2019 (iMac 19.1 "27 and iMac 19.2 "21,5) macOS version (18E2034)
The iMac E2019, currently in store, is manufactured entirely in China and is manufactured (usually) in 2019. Therefore, the first four digits of the serial number are all C02Y
The next digit is the month of production, but the product in the store is 9 weeks or 8 weeks. There were many for 9 weeks. The ninth week of 2019 is the week of 2/26 to 3/4 and the eighth week is the week of 2/19 before 2/25.

The next three digits are called the production line number, which is a specific product number. The last four digits are the model code.
iMac 19.1: JV3Q, JV3P, JV3N and JV40
iMac 19.2: JWDW and JWDX
Example: C02Y9xxxJV3Q

Board serial number
The serial number of the iMac E2019 board currently in store seems to be made in China as the main unit. The year of manufacture was, of course, 2019, and the manufacturing week was one week before the main unit, either 07 or 08 weeks. The second half of the plate serial number has a plate code that indicates the type of board.

BBcode:
iMac19,1: LNV9, KDP0
iMac19,2: KGQG
Example:
C02908xxxxxLNV9xx

IDs
iMac19, 1: Mac-AA95B1DDAB278B95
iMac19, 2: Mac-63001698E7A34814
ROM: 220.250.368.0.0

Examples:
./macserial --model iMac19,1
C02YC017JV3Q | C02909207GULNV9AD
C02Z7JYAJV3Q | C02933102GULNV9JA
C02YNYZNJV3Q | C02918200GULNV91F
C02ZP0XSJV3Q | C02946802QXLNV91H
C02YRAYQJV3Q | C02921200GULNV9A8
C02YN3ZGJV3Q | C02918403GULNV9CB
C02YM085JV3Q | C02917403CDLNV9AD
C02ZC0AFJV3Q | C02936303GULNV91F
C02Y800NJV3Q | C029078024NLNV9FB
C02ZP2YPJV3Q | C029467004NLNV91M

./macserial --info C02YC017JV3Q
Country: C02 - China (Quanta Computer)
Year: Y - 2019
Week: C - 10 (05.03.2019-11.03.2019)
Line: 017 - 41 (copy 1)
Model: JV3Q - iMac19,1
Valid: Possibly

Shown It is manufactured the tenth week of 2019. It's only two weeks after the first product, so I think it's fine. I think maybe some future numbers in the next few months are probably fine. However, since the first product is manufactured in the eighth week, I think it is better to avoid the 2019 number 1-7 weeks before this.

If you already have a serial number, ./macserial -mlb <series> will generate a series for the logic board manufactured the previous week, in the same country.

./macserial --mlb C02YC017JV3Q
C02909108GULNV9AD


Let's write a section of SMBIOS with the configuration closest to the iMac 19,1. If you use the serial number and serial number of the plate in the previous example, it will be as follows. (Please use your own number) SmUUID, generate and type the uuidgen command of the terminal appropriately.

Example:
<key>SMBIOS</key>
<dict>
<key>Board-ID</key>
<string>Mac-AA95B1DDAB278B95</string>
<key>BoardSerialNumber</key>
<string>C02909108GULNV9AD</string>
<key>EfiVersion</key>
<string>220.250.368.0.0</string>
<key>ProductName</key>
<string>iMacm19,1</string>
<key>SerialNumber</key>
<string>C02YC017JV3Q</string>
<key>SmUUID</key>
<string>XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX</string>
</dict>

So they should be usable in the latest version of Clover?

Just tried to update smbios from 18,3 to 19,1, and got the Stop sign on boot.

I read somewhere that the new iMac is using its own build of 10.14.4, perhaps that is needed as well.

Could someone help me out as to how I would go about downloading that build of macos?

Installed the public beta of 10.14.5, and the 19,1 SMBIOS is now working.

Interestingly, I'm still seeing "Processor - 3.6 GHz Unknown" in About My Mac. Not sure why I'm not seeing i9-9900K.
