The manual page for kmutil give important info about retriggering security approval for kexts. There may be utilities floating around that do help do this at a higher level.īut I'm not going to write a script to do that since I don't even get what we are looking for, I suspect this permission stuff is a red herring, only there because Focusrite copied it from the link above, if a vendor has a broken installer leaving incorrect file permissions just check their kext file permissions.įor most people ideally if there is a device not working/apparently not present issue they should to start with running kextstat (or kmutil on macOS 11 or later) and seeing if the relevant kext is loaded or not. Now repeat that for files (type f) combined with different name wild cards to check say that plist and executable and other files in these bundles are the permissions expected. As a trivial example, show me all /System Extensions where directories are not the expected 755 permission (should return no output).įind /System/Library/Extensions -type d ! -perm 755 But what/why is setting wrong permissions, a broken installer? This should just not happen often.įor fancier debugging if permissions were broadly screwed up, I would build a script that looked for the permissions on items within the kext bundles, things like directories and binary components being executable, and other files not being). If I suspected kext's (and all the actual files that make up a kext bundle) had the wrong permissions I'd be looking at what is wrong and not clobbering everything, setting incorrect permissions on many files. But no I would not just run the examples I gave to correct the wildcarding stupidity.Īnd oh well here explains where Focusrite get their support advice from, the muppets copied and pasted from this generically poor advice: Obviously you don't want to do the last step, which is only for the Focusrite gear, but I would certainly do the kext rebuilding.Įric - what macOS version was this on? What exact driver package were you installing? Sudo kextload /Library/Extensions/FocusritePCIe.kext Once rebooted, manually load the kext with the following command: Then restart the computer for the changes to take effect. Next, enter the below command to rebuild kext cache: Type each of the following commands (separately) in Terminal. I suggest trying the following to rebuild the kext cache and manually load the driver. It seems that the driver kext isn't being loaded by the OS upon a reboot. I'm going to try this to see if it helps with the Avid HD Driver. I had problems with our Focusrite drivers not loading on new Mac Pros and got they email from Focusrite support. This is only after the latest 2021.10 update. I have never had this problem in the past. I followed all instructions and did this and I still no longer get the driver showing up when I reboot my computer. Later in the article, it says that if this is the case, to boot in recovery mode and force an update to the MacOS prelinked kernal. This is bad because my studio is rented out to multiple engineers who I do not want messing with Terminal and I don't want to give my password to. However, when I reboot, it won't show unless I type the command in Terminal. When I type the command in Terminal, the HDX driver does show up and Pro Tools launches and I can move forward. After searching around, I found this article: So this morning I installed Pro Tools 2021.10 and the Driver download 2021.10 for my Mac Pro 2019 on Big Sur 11.6.Īfter installation and restarting the computer multiple times, and allowing all Avid stuff in my system preferences I could not get the HDX driver to show up in Audio MIDI Set-up (so of course not in Pro Tools).
