Nevertheless, keep in mind that if you visit developer.apple.com/downloads, you can only find 10.3-10.6 OS X operating systems there. Newer versions are not available because starting Mac OS X Snow Leopard 10.7, the App Store has become the only source of updating Apple OS versions.
Before you do it, the best advice is to back your Mac up so your most important files stay intact. In addition to that, it makes sense to clean up your Mac from old system junk files and application leftovers. The easiest way to do it is to run CleanMyMac X on your machine (download it for free here).
A new feature included with GarageBand '09 and later is the ability to download pre-recorded music lessons from GarageBand's Lesson Store for guitar and piano. There are two types of lesson available in the Lesson Store: Basic Lessons, which are a free download, and Artist Lessons, which a user must purchase. The first Basic Lessons for both guitar and piano are included with GarageBand. In GarageBand 10, many sounds (aka patches, which Apple refers to as 'audio units') which are listed within the sound library are dimmed and unusable until the user pays an additional fee which allows the utilization of those sounds, bundled with the guitar and piano lessons. Attempting to click on and select the dimmed audio units to apply to the track causes promotional prompts to appear, requiring the user to log on with their Apple ID and furnish credit card information before knowing the price of the bundle.
The Sound Library was added in November 2017 with the 2.3.1 update and lets the user download additional free instruments, drummers and loops released as Sound Packs that are added to the app over time.
