Hi Ian
QLab 5 is in a sort of weird space with regards to macOS 26 Tahoe… we feel like we’ve fixed the most obvious issues, but there are still a few known bugs which we have not yet been able to fix. There’s also still an enduring sense of not yet knowing whether we’ve seen the whole playing field, as it were.
I know that’s not a very satisfying answer but it is the true answer.
My personal recommendation is to remain on Sequoia unless you have a specific need to update to Tahoe, but that is only my opinion.
If you’re using QLab 4, do not update. QLab 4 is incompatible with Tahoe.
Best
Sam
