Entropic Posted January 28, 2021 Share Posted January 28, 2021 Hi everybody. I'm following Jake Lo guide to install Big Sur 11.1 (Dell Latitude E7440) without issues, but when i'm going to install alc_fix from Download folder, terminal says: "zsh: no such file or directory: ./install". Thought it was due to using szh instead of bash and tried with a bash session with ./install.sh, and it start to install: "Installing ALCpluginFix v.1.7", but then it says: "mkdir: /usr/local/bin/: Permission denied", ask for the password but can't create the folder. I even created manually the folder /usr/local/bin with sudo mkdir and then I got to install ALC_Fix, but after rebooting system, I lost the sound (no sound device). I'm sure I'm doing something wrong... Any idea? Thanks a lot. Entropic. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 28, 2021 Moderators Share Posted January 28, 2021 You'll need to boot into Recovery mode, disable SIP. Boot to normal mode, run the script again. Once done, reboot to Recovery mode to re-enable SIP. Link to comment Share on other sites More sharing options...
Entropic Posted January 28, 2021 Author Share Posted January 28, 2021 Ok. Disabling SIP can be done typing "csrutil disable" from Terminal in Recovery mode, but I'm not sure how to getting in Recovery mode. ¿Do I have to delete HideAuxiliary from kernel boot properties in Opencore config.plist and I will see Recovery entry in Picker or there is a way to get all the entries (maybe pressing spacebar)? I can't test it because I won't have the laptop until tomorrow. Thanks again for helping me with that. Entropic. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 28, 2021 Moderators Share Posted January 28, 2021 Yes, press spacebar to review the options if you have HideAuxiliary enabled. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 28, 2021 Moderators Share Posted January 28, 2021 Just to be clear, if you have HideAuxiliary set to YES, it hides the Recovery Boot option in OC Picker. Link to comment Share on other sites More sharing options...
Entropic Posted January 29, 2021 Author Share Posted January 29, 2021 Thanks very much, Jake Lo. It's done and working now. I will describe te entire process I followed under Big Sur 11.1 just in case someone has the same problem: 1. Reboot system with Recovery partition. If you don't see Recovery in Opencore Picker, press spacebar and you will see it. 2. In Recovery screen, click Tools>Terminal and write: csrutil disable 3. Press RETURN on your keyboard and reboot system in normal mode (main OS X partition). 4. Download alc_fix.zip. Open Download folder and unzip file. 5. Open Terminal and open a BASH session typing bash 6. Press RETURN 7. type in Terminal with Return after every order cd Downloads cd alc_fix sudo ./install.sh 8. After the last Return you will see a message in Terminal, ending with "Done!" 9. Type in Terminal exit 10. Press Return and close Terminal 11. Reboot again in Recovery mode pressing spacebar if necesary. 12. In Recovery Screen, click Tools>Terminal and write: csrutil enable 13. Press RETURN and reboot system in normal mode again. 14. After writing your password you will see a message saying: "AlcplugFix is an app downloaded from INTERNET. Are you sure you wnat to open it?" 15. Choose OPEN button and that's all. I hope it will be useful. Thanks to Jake Lo. As usual, he solved the trouble. Entropic. 1 Link to comment Share on other sites More sharing options...
