I bought a PreSonus Audiobox USB back around 2009 and it came with Steinberg CUBASE LE4 Music Production Software. The installation goes to the very last “inch” and then locks up. I can’t close it unless I do a hard shut down. I’ve uninstalled the 'eLinscencerControl" and reinstalled it and retried installing LE 4 but it does the same thing. This is following the Steinberg troubleshooting guidelines. I have everything they say I need and yet it won’t install.
Hi and welcome to the forum,
Cubase LE4 is quite old. Most probably it’s not compatible with your MacBook Air.
Please get in contact with your local Steinberg Support and ask for the update to the current Cubase LE 13.
