Garage Band

Hey there 1maddjack,

Thanks for reaching out to Apple Support Communities. I understand you want to know if you can download a previous version of GarageBand for Mac OS X 10.10.5. I’ll be happy to help.

There isn’t an a version of GarageBand currently available for Mac OS X 10.10.5. The current version requires macOS 10.13.6, you can read more about this here:

‎GarageBand on the Mac App Store

If you want, you can see about updating your software here:

How to update the software on your Mac

Let me know if this helps.

Maybe someone can chime is as to whether Garageband on the last Retail DVD of iLife (iLife '11) will work with 10.10.5
