[Isadora 2.6.1] Do not upgrade to Mac OS Mojave

Woland

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?

@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.

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.

Hi,

I'm a long-time Isadora user, from when we would exchange emails with Mark about problems we were having and he post a software fix for your issue. I had been using the same computer for about 6-8 years and my patch was working great so I never checked Troikatronix for updates or whatever. Finally my computer crashed and I bought a new mac and thought, "Great I will finally upgrade Isadora, I can't wait for the new features." After installing 2.6 and not being able to open it, I read that it doesn't work with Mojave. I can't uninstall Mojave because it's necessary for the other software I use, mainly the Adobe Cloud. I can't afford buying another computer form video processing so I'm stuck until Isadora 3 comes out. Is there any timeline for Isadora 3? Is there any beta versions available?

Thanks,
Antonio

There is another option for installing and using Isadora 2.6

You can create a small partition (48-64gb) and install an older mac OS on that system (high sierra is fine).

It's not ideal, but it will bridge the time until Isadora 3.
