Hello, first close the internet, open readme.txt, do the steps, then paste this to terminal
- code-select --install
sudo codesign --force --deep --sign - /Applications/Ableton\ Live\ 11\ Suite.app
sudo xattr -d -r com.apple.quarantine /Applications/Ableton\ Live\ 11\ Suite.app
sudo chmod +x /Applications/Ableton\ Live\ 11\ Suite.app/Contents/MacOS/*
In the end open the Ableton, in the preferences close the automatic update, after that below there is authorize offline, click that. After that write the serial to the 2R2 Keygen (open the keygen with Crossover). drag and paste the that created authorization file on the ''authorize offline''
Last but not least, go to settings on the mac security and privacy, security wall, and then open the lock and remove the internet connection of Ableton. Then, you should be fine.
