ssdtPRGen.sh

You can download the latest Beta of ssdtPRGen.sh by entering the following command in a terminal window:

curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/Beta/ssdtPRGen.sh

You can verify the size of the downloaded file with:

wc -c ssdtPRGen.sh

That should match with what you see [here] (https://github.com/Piker-Alpha/ssdtPRGen.sh/blob/Beta/ssdtPRGen.sh). Right now that is 142KB. A failed download is usually much smaller (like 447 bytes or so).

This will download ssdtPRGen.sh to your home directory (~) and the next step is to change the permissions of the file (add +x) so that it can be run.

chmod +x ~/ssdtPRGen.sh

Note: ssdtPRGen.sh v15.1 and greater require a working Internet connection so that it can download configuration data and command line tools. You can also download a complete zip archive by entering the following commands in a terminal window:

curl -o ~/Library/ssdtPRGen.zip https://codeload.github.com/Piker-Alpha/ssdtPRGen.sh/zip/Beta
unzip -qu ~/Library/ssdtPRGen.zip -d ~/Library/
mv ~/Library/ssdtPRGen.sh-Beta ~/Library/ssdtPRGen
rm ~/Library/ssdtPRGen.zip

User Defined Processor Data

The script was initially written for Intel Core processors and the processor data for (most) Intel processors should be readily available, but I have no intention to add the processor data for older processors. No worries. You can add the data yourself to: ~/Library/ssdtPRGen/Data/User Defined.cfg A few examples are there to help you.

Unknown CPU error

The processor data for your processor may not (yet) be available, and this is – most likely – why you get the error. The other problem is a common user-error where people use the wrong processor label i.e. i76850k/i7-6850k instead of i7-6850K. If the latter is not the problem that you are facing, and you known that the data for a new processors is missing, then please open a [Github issue] (https://github.com/Piker-Alpha/ssdtPRGen.sh/issues/new) with the missing processor data (link to data). For older pre-Core I Intel processors see: ~/Library/Data/User Defined.cfg

Bugs

All bugs, so called 'issues', should be filed [here] (https://github.com/Piker-Alpha/ssdtPRGen.sh/issues). If the script fails to generate a SSDT then please attach the output of: ./ssdtPRGen.sh -d 2 and compressed: ~/Library/ssdtPRGen/ACPI folder. If you are using processor data from Data/User Defined.cfg then I also need to know what that data is.

Please do not use my blog for this. Thank you!
