Garageband file has giant file size

Hi bac26,

welcome to the Apple (user-to-user) Community!

Re: "I'm making a song in garageband for mac and the file size is 800 mb. When i try to delete or make a new track the app buffers for minutes on end or crashes".

Am wondering whether your Mac has sufficient memory / storage space in which to operate smoothly.

(NB: This is the storage space on your Mac ... iCloud storage is different)

Eg: A Mac generally needs around 50 Gb free storage space in order to do all you ask it to do:

If you find your Mac is short on space in which the operating system can work smoothly:

It is wise to back-up all of your data securely, before making space:

Else, if your Mac already has at least 50Gb storage space free:

All the best :-)

One more thing - close all other apps, when you are working on your project, so no other app will hog the available memory. It may help to restart the Mac before continuing to work on the project.

Not all sound fonts are compatible with the current GarageBand version. Make sure, that any plug-ins you have installed are compatible with your current system version. After upgrading to GarageBand 10 I had to uninstall all of my audio components and VST plug-inns, because they caused GarageBand to crash.

As a test, can you open your project with your Mac running in Safe mode? Safe Mode will disable all incompatible system extensions.
