All news and info and updates about 64bit (compatibility with "Monterey" and later, including mac ARM) will be posted on this page, everything I know is on this page (so writing to me won't yield any further info ;-)

Why? Because Apple supports 32bit software up to Mojave. But for Catalina and later, does NOT support 32bit software. FAQ below:

64bit Beta is Ready enough to use

The 64 bit version of kJams, which runs on Win11 or macOS 13 and later, including mac ARM). Here: ready for Beta Testing.

Get Notified

To get notified of major events, join the mailing list.

Is kJams (32bit) currently compatible with "Catalina" and later, including mac ARM?

No, the classic, 32bit version will not run kJams under macOS Catalina. It only runs on macOS 10.14.6 and no other

Why not?

The classic kJams is a 32bit application, and the newer OSs do not support 32bit apps.

Which macOS is kJams (32bit) compatible with?

kJams 32bit ONLY runs on macOS 10.14.6 (Mojave).

When will kJams be able to run under Monterey and later, including mac ARM?

For beta testing, Today. For running a real show: see this link.

How can I run kJams (32bit) today if I have "Catalina" or later?

If you have an Intel mac, you can use Virtual Machine software such as Parallels Desktop or VMWare Fusion. Be aware they unfortunately do NOT support multiple monitors. Then install macOS Mojave, see below for how to download it. There is a forum discussion here.

If you have an M1 mac, sorry, you can't.

Can I downgrade back to macOS 10.14 Mojave?

If you have a mac produced PRIOR TO October 2019, then YES, you can downgrade to, or otherwise use, Mojave. Try one of the following:

  1. use your time machine backup from before the upgrade
  2. reinstall from scratch using a USB stick. You can make a bootable Mojave Installer USB stick using DiskMaker. BACK UP your kJams installation before you downgrade, Start with this article (the "old computer" is later than Mojave, the "new computer" is Mojave). During the "Cloning" phase, use the "Backup and Restore" sections.
  3. install Mojave on an external drive and boot from that

How do I download Mojave?

Dave says: “I'm sorry I dropped the ball”

I tried really hard to inform all users of kJams not to upgrade past Mojave:

  1. directly within kJams: a notification would pop up
  2. on the kJams web site: prominently at the top of every page
  3. in the newsletter, i sent it out over a year before Catalina was released, and a few times since
  4. on my Facebook page
  5. via my Twitter account

Unfortunately if your auto updater was broken, because you were on a very old version of kJams, you never got the in-app notification. If you never visited the web site, and you weren't subscribed to the newsletter, and you never went to the facebook page, or saw the tweets, then sadly i was not able to reach you in time. I am truly sorry about that.

Can I track your progress?

Yes you can!

I have another question
