This group of parameters is used to mask your PC as a Mac. Clover will do this task automatically based on the given processor, video card and signs of mobility. However, you may choose differently. Get the MacTracker application, choose a model you like and find matching values. Chameleon Wizard may help you with this task. There is not much to comment here, these values are not for beginners. If you know them - change them; otherwise leave it. Calculating them is mostly not possible.
ProductName
<key>ProductName</key>
<string>MacBook1,1</string>
SMBIOS.table1->ProductName
You can set only this value and Clover will adjust the rest of the parameters automatically according to the model, so you can leave them out. Otherwise your custom values will be preferred.
Clover has built-in definitions for following models:
MacBook1,1
MacBook2,1
MacBook4,1
MacBook5,2
MacBookPro5,1
MacBookPro8,1
MacBookPro8,3
MacBookPro9,2
MacBookAir3,1
MacBookAir5,2
Macmini2,1
Macmini5,1
Macmini6,2
iMac8,1
iMac10,1
iMac11,1
iMac11,2
iMac11,3
iMac12,1
iMac12,2
iMac13,1
iMac13,2
MacPro3,1
MacPro4,1
MacPro5,1
All other models require setting all fields manually.
In case the model is not set, Clover will automatically choose one for you.
Some parameters like BoardSerialNumber
should be generated and specified manually to be unique though.
SmUUID
<key>SmUUID</key>
<string>00000000-0000-1000-8000-010203040506</string>
This is the UUID, which is written into the SMBIOS table. Apparently it makes sense to fill the last pairs of digits with the MAC address of your ethernet card. This UUID will also be used in case CustomUUID is missing.
FirmwareFeatures
<key>FirmwareFeatures</key>
<string>0xC0001403</string>
SMBIOS.table128->FirmwareFeatures
These digits exceed the standard SMBIOS and are part of Apple's specification. Different real Macs show different values and no description of the meaning exists. The only clue is provided by the sources of the bless command:
&& (featureFlags & 0x00000001)) {
contextprintf(context, kBLLogLevelVerbose, "Legacy mode suppported\n");
Therefore, we too need an odd number here.
BoardSerialNumber
<key>BoardSerialNumber</key>
<string>C02032101R5DC771H</string>
SMBIOS.table2->SerialNumber
Clover will use one specific value here, which needs to be replaced by your own serial number. It is required for working iCloud and iMessage services. The length must be 17 digits, consisting of letters from the Latin alphabet and numbers. The serial number used by Clover is most probably banned already.
BoardType
<key>BoardType</key>
<integer>10</integer>
SMBIOS.table2->BoardType
This parameter was introduced for the MacPro, which uses 11
(ProcessorBoard) instead of 10
(Motherboard), apparently for historical reasons. The effect is not clear, however it can be seen inProfiler.
Mobile
<key>Mobile</key>
<true/>
Usually Clover will automatically detect the mobility of a system, e.g. if is powered by a battery, needs energy saving, or not. Change it to trick the system into thinking that a battery is not available, or otherwise.
ChassisType
<key>ChassisType</key>
<string>0x10</string>
SMBIOS.table3->Type
Used as an indirect indication for platform mobility. Here is a table according to SMBIOS standards:
Type | Value |
---|---|
MiscChassisTypeOther | 0x01 |
MiscChassisTypeUnknown | 0x02 |
MiscChassisTypeDeskTop | 0x03 |
MiscChassisTypeLowProfileDesktop | 0x04 |
MiscChassisTypePizzaBox | 0x05 |
MiscChassisTypeMiniTower | 0x06 |
MiscChassisTypeTower | 0x07 |
MiscChassisTypePortable | 0x08 |
MiscChassisTypeLapTop | 0x09 |
MiscChassisTypeNotebook | 0x0A |
MiscChassisTypeHandHeld | 0x0B |
MiscChassisTypeDockingStation | 0x0C |
MiscChassisTypeAllInOne | 0x0D |
MiscChassisTypeSubNotebook | 0x0E |
MiscChassisTypeSpaceSaving | 0x0F |
MiscChassisTypeLunchBox | 0x10 |
Clover will use a value according to the set Mac model, like it is used in real Macs. The effect, except mobility settings, is unclear.
ChassisAssetTag
<key>ChassisAssetTag</key>
<string>LatitudeD420</string>
SMBIOS.table3->AssetTag
This field is never used with real Macs. We can use it for our own purpose, for example in theHWSensors project.
Trust
<key>Trust</key>
<true/>
Used to give priority to memory descriptor values found in SMBIOS or SPD. Change if your memory is described incorrectly in Mac. Default is <true/>
.
Memory
<key>Memory</key>
<dict>
<key>Channels</key>
<integer>2</integer> OR <string>1</string>
<key>SlotCount</key>
<integer>24</integer> OR <string>4</string>
<key>Modules</key>
<array>
<dict>
<key>Slot</key>
<integer>0</integer> OR <string>5</string>
<key>Size</key>
<integer>2048</integer> OR <string>4096</string>
<key>Frequency</key>
<integer>1600</integer> OR <string>1333</string>
<key>Vendor</key>
<string>Some Company</string>
<key>Part</key>
<string>123456ABCDEF</string>
<key>Serial</key>
<string>ABCDEF123456</string>
<key>Type</key>
<string>DDR/DDR2/DDR3</string>
</dict>
</array>
</dict>
Inject custom memory module tables into SMBIOS if original SPD and SMBIOS provide incorrect or incomplete information.
Channels
- Number of hardware channels supported by your memory chipset, usually two.SlotCount
- Total count of memory slots in your system. Max 24 (for now).Modules
- An array of INSTALLED modules, if your slot is empty don't include an entry for it.For each module:
Slot
- Physical slot location in which the module is installed.Size
- Size of the module in megabytes.Frequency
- Speed of the module in megahertz.Vendor
- Memory manufacturer namePart
- The part number identifier.Serial
- The module's serial number.Type
- The memory module's type.
