Hi I have some old Qlab2 show files. I'm able to open the Qlab pprogram on my old MBP, but the show file say that it's a documents. I can't seem to convert it back to a Qlab file. Anyone have an idea what to do?

Does the file have a .cues extension?

It says .qlab. If I look at the file under "Kind" it says Qlab 2 Document

That's a QLab 1 file that will only open in QLab 1

While QLab v2 - v5 will update, incrementally to the next version. QLab 1 files can't!

From the QLab 2 Manual:

Transition from version 1.x

QLab 2 may be safely installed on a machine running QLab version 1.x; the two programs will not interfere with each other.

QLab 2 will not read QLab 1.x workspace files.

QLab 2 workspace files now use the file extension ".cues".

and from the horse's mouth in 2010:

QLab version 2 can't read version 1 workspace files. The program was
rewritten substantially and there was not a way to translate the
workspaces from version 1 into version 2 and guarantee they'd behave
in the same way.

You'll need to either rebuild the workspace in version 2, or, probably
the best option, is simply run the workspace as built in version 1.
