Guess what:

Entering this string into terminal:

defaults write com.apple.garageband MD_AllowVirtualCores -bool yes

Makes Garageband hyperthreadable since it was built on logic.

The string above is based on the command that provides multithreading capability back to Logic after version 9.12.



WOW!

I know for Logic users it's not a big deal but for Garageband users it will give those users additional horsepower if they're running any hyperthreadable processors.

Unless, of course, it actually SLOWS DOWN performance (as it does with Logic on some configurations, which is why it's turned off).

If you're doing stuff in GarageBand where hyperthreading on or off makes a noticeable difference, I have to question your judgement. It might be time to upgrade the toolset to Express or Pro.
