How do I downgrade MacOS High Sierra to MacOS Sierra, El-Capitan or Yosemite?
Hi, I've purchased an Apple iMac (4K Retina Display, 21'' Inch) for my production (recording studio) but it's already updated with the latest 'MacOS High Sierra (Ver. 10.13.1). My audio interface's driver [Lexicon IO 42] doesn't support on the latest update and it shows '' Discontinued '' every time when I visit Lexicon's official website for downloading A.I Driver [for MacOS High Sierra, ver. 10.13.1]. Would really appreciate if anybody could help me to solve this issue. Thank you in advance!
