Linux is a leading server operating system, and runs the 10 fastest supercomputers in the world.
Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers, routers, and video game consoles, to mainframes and supercomputers. Sudo rm -r /System/Library/Caches/ refers to the family of Unix-like computer operating systems using the Linux kernel. The following post and these commands helped me recompile the kext-cache:
On Mac OSX Yosemite the kext-cache is located differently. The chmod / chown commands as written in this post worked fine. After some research on installing extensions manually I came upon this post and i compared the file-permissions and owners with other extension-files and saw, that they were different. I even had error messages after reboot, that some extensions could not be installed.Ī “sudo kextload MyKext.kext” said something about missing file permissions. I tried to re-install the extensions by moving the extension-files back, but nothing happened. After my late 2011 macbook pro had the known GPU fault, i disabled some Extension (by copying them out of the extensions folder) to at least save my data before an official apple retailer repaired the motherboard on warranty.Īfter that, I still had slow bootup and strange graphical behaviour. Similarly, you can remove an item from the same /System/Library/Extensions/ folder to uninstall a kext file, rebooting the Mac again for the change to take effect.Īs you can see this is more time consuming than relying on an app installer to place a kext itself, and it’s a bit more complex than the alternative like Kext Drop, so ideally you’ll just one of the installer applications instead, because most kext files are coming from an application installer anyway, right? Nonetheless, if you can’t use an installer app or a kext modifier app for some reason to install a kernel extension, the manual installation method outlined above works great in all versions of OS X. You can query a list of the active kernel extensions in OS X with the kextstat command to be sure, use grep to limit the results. The kernel extension should now be installed. Type the following commands at the terminal, replacing the kext name with the one you are installing.kext file(s) to /System/Library/Extensions/ You’ll need to use the Terminal to complete the kext install, this process is the same in all versions of OS X:
