Every Single Mac Board ID from 2006-2021 + M1 Apple Silicon DeviceIDs
This page will be updated with the latest list of Mac BoardIDs, Model IDs and Machine Models. Apple started to document attributes like ModelID on the page below but stopped after 2017.
https://support.apple.com/en-us/HT201608
Most BoardID’s are scattered all over the web but are not all in one updated page. I started with the version Intel based version and will update when new BoardID’s are introduced.
Can I upgrade or downgrade macOS on my Mac?
I wrote an article including every Intel Mac since 2006. The list includes the lowest and highest macOS version that you can install on your Mac.
mrmacintosh.com/can-i-upgrade-or-downgrade-macos-every-mac-from-2006-2020/
What is the BoardID used for?
The macOS installer.app uses the boardID value to figure out if the Mac Model is supported when the user starts the install.
You can find this list inside the macOS installer.app. Look for the InstallESD.dmg After you mount the DMG navigate to /System/Library/CoreServices/PlatformSupport.plist
Inside this plist you will find the list of logic board ID’s that installer supports.
How do I find the Mac BoardID?
To find your BoardID use this command.
ioreg -l | grep -i board-id
The output should read like this
"board-id" = <"Mac-942C5DF58193131B">
How do I find the Mac DeviceID?
To find your T2 DeviceID use this command. HT @eholtam for the command.
/usr/libexec/remotectl get-property localbridge HWModel

DeviceID & ModelID
The macOS Big Sur installer is now checking T2 Macs for the DeviceID attribute. Hat Tip #1 goes to @rickmark who maintains the main DeviceID list here. Help us fill in the blanks! Hat Tip #2 goes to @grahamrpugh who found the new code in Big Sur.
// Next compare T2 devices against the list of supported deviceIDs.
…
// For legacy hardware T1 and older, we use boardIDs

8. Xserve – (2006-2009)
I almost forgot about Xserve. How could I forget about one of my favorite most reliable Macs ever created? The Xserve was introduced on May 14, 2002. The First Generation was based on a G4 Processor. The 2nd Generation was based on the G5 and the 3rd and final Generation was based on Intel’s Xeon Processor.

Greetings, mrmacintosh!
Just a interesting note:
I have a MacBook2,1 (13-inch C2D Mid 2007) – not in your list -, but my board id is the same as MacBook2,1 (13-inch C2D Late 2006) Mac-F4208CAA
hello
i need macbook 6,1 firmware and i cant find it in the net. please help me how can i fint that?
thank you
Firmware is installed by the operating system when you install macOS. Best bet would be to obtain a Leopard or Snow Leopard disc and install. That should help any issues you’re having
Hi – I think your info above may be slightly wrong, for my own model of Mac. I have a MacBook Pro (Retina, 13-inch, Late 2012), its model identifier is reporting as MacBookPro10,2 and its board-id is Mac-AFD8A9D944EA4843. You have those two listed as a 2013 MBP and then you have a blank row for the (late) 2012 MBP – so I think if you’re happy to accept this info that those two rows need updating. (I have a screenshot of all the info, but I can’t see a way to attach it!) Many thanks for this useful page. MB
My iMac 18,2 has “board-id” = which is not in the iMac table.
I didn’t this model in your database:
Mac model = iMac19,2
Serial number =
Logic board ID = Mac-63001698E7A34814
Hope that helps

Hello Mr. Macintosh
I have a MacBookPro8,1 (13-inch, Late 2011) and its Board ID is: “board-id” = <"Mac-94245B3640C91C81"
I also have a MacBook Pro8,2 (15-inch, Late 2011) and its Board ID is:
"board-id" = <"Mac-94245A3940C91C80"
I saw that in your list, you don´t have them, maybe you can add them.
Best regards,
Hugo Grob.
This is great! I was looking for a board ID and model number for my hackintosh laptop (Surface Laptop 3 is now MacBook Air 2019). All I did afterwards is surf eBay for a matching serial number (easy when people show System Profiler!) and bam! I have a working “MacBook”
