moshau Posted December 12, 2020 Share Posted December 12, 2020 (edited) Hello everyone. For reasons other than that, I had to reinstall mojave 10.14 on my latitude 7480. Most devices work, except the audio, I was checking and it must be from ACL256 ID> 21, that worked before reinstalling. I would like to know the steps to upgrade to Catalina or why not, to Big Sur, but I don't know how. Otherwise I stay with Mojave, hoping to have your help to activate the audio. I would like to know if I can update from olarila Catalina or big sur or should I do it from Apple? Where can I get the necessary and updated steps for my 7480? Thank you Edited December 12, 2020 by moshau Link to comment Share on other sites More sharing options...
