Important! macOS 10.15 Catalina Notice


Apple is poised to release its next operating system, macOS X 10.15, “Catalina,” sometime in October of 2019. PreSonus has been working with Apple to qualify pre-release versions of this new OS with all of our products.

We have found changes in Catalina that affect compatibility with PreSonus hardware and software. Remain on current versions of macOS until further notice. We ask that you please wait for us to announce compatibility before updating your OS.

In the meantime, please be advised:

  • Studio One version 4.5.4 is required to run Studio One under 10.15.
    • Izotope Neutron Elements and Klanghelm SDRR2Tube will not install under 10.15.
    • Arturia Analog Lite, and StudioLinked Trophies will at first not install— you must CTRL+Click (or right click) and select “Open” to install them.
    • Check your third-party plug-in developers’ websites for updates, as many of them may not install or run correctly under 10.15, and will need updates themselves to work correctly.
    • Some of the Studio Magic Plug-ins will not run under 10.15.
  • Universal Control 3.1 and older versions are not supported and will not open sample rate settings correctly on macOS X 10.15 Catalina.
    • An update to Universal Control will be necessary to access these settings. This update will be announced as soon as it’s ready for use with 10.15.
  • Universal Control 1.7.6 for FireStudio interfaces and StudioLive 24.4.2, 16.4.2 and 16.0.2 will not install on macOS X 10.15 Catalina.
    • An update to Universal Control will be announced as soon as it’s ready for use with 10.15.
  • StudioLive Series III mixers will not work with macOS X 10.15 without a firmware update.
    • We are planning a public beta of this firmware update to be available soon after 10.15 becomes available.
  • StudioLive 16.0.2. USB will not work with 10.15, please stay on 10.14 or a previously-supported OS until further notice.

We will provide an update when we have qualified 10.15 for use with our products and what updates are needed to ensure proper compatibility.

Thank you!

    Thank you for the reply. I have been a Studio One User for years and I must say it has come a long way.

  • Hey NatTurnerLives, we e-mailed hundreds of thousands of users about this issue, posted on our social media pages, our blog, our knowledge base, and our Facebook groups, and included it in the news feeds of Studio One and I’m sorry we weren’t able to reach you.

    What e-mail address do you have registered with us? I will make sure you’re opted in to receive e-mails for this sort of thing.

    I didn’t see this warning and have already updated my OS to Catalina. My UC is not working unless I open studio one. The drivers don’t seem to support Catalina as of yet. I use UC outside of Studio One. It would have been nice if I received an email to advise. I’ve been going crazy all day trying to figure out why my inputs are not working or even registering in UC.

  • Hello,
    estimated date ?

    OK, it’s probably not a big deal to downgrade but still — would be nice to know the timeline for compatibility. thx!

  • Jeffrey Belka

    With the upcoming upgrade to UC, will the lag issue between UC and AI series consoles be addressed????

  • daslicht

    Will the FaderPort Classic keep working under Catalina ?

    Thanks for the notice. Any estimated date for compatibility? I’m looking to upgrade my Mac soon and if it ships with Catalina, downgrading to a previous version of macOS will be a chore.
