This piece of code runs another function called validateSoftware() and if that returns false, this function does so as well. The first is a section that looks like the following: Open that file up in a text editor of your choosing, and we'll be looking for a couple things. This is where the actual build number checks happen - and so, this is where we leverage our HackMasterness. When you navigate into that directory, you'll see a couple things - but the one we'll set our crosshairs on is the Distribution file.ĭon't be fooled by it's binary file appearance or lack of extension! It's really just an XML text file with a bit of javascript wrapped inside. This command will create a new folder called Web-Driver-Expanded on your desktop and populate it with the expanded contents of the WebDriver-378.10.10.10.20.109.pkg we downloaded before. pkg file here) ~/Desktop/Web-Driver-Expanded Luckily for us, we've got some built-in tools that can help! Fire up the Terminal and do the following: The first thing we'll need to do is get at the files inside the package. You can download that - install it, and move forward with things - yay! The downloadURL field actually contains a direct link to the web driver package. If you load up the manifest, then search for your build number, you'll see something akin to the following: You can load that page and search for your build number within - for this instance, we'll assume you're on the newest build of 10.13.1 which at the time of this writing is 17B1003. Nvidia keeps an online manifest that is an XML property list (it looks a lot like HTML if you're familiar) of current web driver versions, build numbers, etc. Once you have your build number, you can download the corresponding web driver install package. NOTE: I will be using example links, driver versions, build numbers, etc in this guide - please make sure that you adjust that information to reflect YOUR setup. This is not something you need to worry about if you're patching the ist locally. This doesn't prevent the nvda_drv=1 NVRAM flag from being removed though as the local NVDARequiredOS value is still checked - so you'll likely want to keep ist -> SystemParameters -> NvidiaWeb set to true. It also lets you keep SIP enabled as you don't need to muck up any code signing by changing files. pkg - but it does let you boot into a newer OS version with an older web driver. This won't help you install an older version - you'll still need to patch the. ist -> KernelAndKextPatches -> KextsToPatchįrom this thread it appears that you can use a ist patch to prevent the Web Drivers from checking against your OS build version.
