Do not upgrade to Mac OS Mojave


  • Tech Staff

    Dear Isadora Community,

    Isadora 2.6.1 and earlier is not optimized for the changes made to MacOSX 10.14.x “Mojave”

    We recommend users working with Isadora 2.6.1 earlier do not install Mojave at this time.

    Our team is hard at work finishing Isadora 3, which is fully optimized for Mojave. Upon release, Isadora 3 or later will be required for Isadora users working on Mojave, but Isadora 3 will also function on MacOSX 10.12.x (Sierra) and MacOSX 10.13.x (High Sierra).



    MULTIPLE VERSIONS OF ISADORA

    Please see this article if you wish to have multiple versions of Isadora installed on the same computer.

    If you accidentally overwrite an older version of Isadora, you can re-download it from our legacy downloads.

    It will be possible to have Isadora 2 and Isadora 3 on a computer if that computer is running MacOSX 10.12.x (Sierra) or MacOSX 10.13.x (High Sierra).

    Isadora 3 is 64 bit and will be supported on MacOSX 10.12.x (Sierra), MacOSX 10.13.x (High Sierra), and MacOSX 10.14.x (Mojave). 

    Isadora 2 is 32 bit and is supported for MacOSX 10.10.x (Yosemite), MacOSX 10.11.x (El Capitan), MacOSX 10.12.x (Sierra), and MacOSX 10.13.x (High Sierra).

    Preliminary tests by our team show that even though Mojave says it supports 32 bit applications, the changes that Apple has made for Mojave render Isadora 2 unusable on the new operating system in some cases.


    BACKWARDS COMPATIBILITY

    Following the way that the software has always functioned,

    You can use a newer version of Isadora to open patches created with an older version of Isadora
    --- but --- 
    You cannot use an older version of Isadora to open patches saved in a newer version.

    Specifically, this means that:

    • Patches created in Isadora 1 can be opened in Isadora 1, Isadora 2, and Isadora 3.
    • Patches created in Isadora 2 can be opened in Isadora 2 and Isadora 3, but cannot be opened in Isadora 1.
    • Patches created in Isadora 3 can be opened in Isadora 3, but cannot be opened in Isadora 1 or Isadora 2.


    If you have any further questions, please do not hesitate to ask us.

    Best wishes,

    The TroikaTronix Team



  • Will it still be possible to run 2 versions? 
    I now have multiple versions on my machine. When I tour with a show made in an older version I like to keep it in that version.

    For example next year I'm still touring with a show made in 2.6.1 will I be able to run that show in 2.6.1 and make new shows in 3 on the same machine?

    I added links in an edit



  • @woland

    My problem is not now. I have multiple versions. My concern is, will it be possible in the future.

    Maybe it is a language thing, Do I understand i correctly: V3 requires Mojave (so will not run on a lower operating system)

    But V2.6.1 doesn't work on Mojave

    So It is not possible to have both versions at the same time?

    Ehh that is a great point that @GertjanB makes.

  • @woland

    That is a relieve. I'll stay on High Sierra for a while.



  • What are the problems detected. I just started a project with a brand new computer with mojave on it and haven't have an issue yet for few days. I don't know if is woth it to downgrade.

    There were severe playback issues when we tested Isadora 2 on Mojave that showed us that even if Isadora 2 ran fine on some Mojave machines, it would be entirely unusable on other Mojave machines. We don't know precisely which changes that were made by Apple have caused Isadora 2 to perform this way on Mojave but we've been too busy with the development of Isadora 3 to investigate it fully. In an ideal world, with a larger team, we would be able to ensure that both Isadora 2 and Isadora 3 perform well on Mojave but due to the fact that we need to focus our energy on Isadora 3 right now, it is not possible for us to spend the time rewriting Isadora 2 for Mojave.
