Hi.
I'm on an older mac (Late 2013 Macbook Pro) which only supports up to MacOS 11 (Big Sur). The most recent version of Garageband supported is 10.4.6 which is what I'm using.
I have Komplete 14 (and 13), so have Kontakt 6.7.1 and 7.2.0 and Komplete Kontrol 2.9.1. I also have an M32 connected, but no audio interface.
Here's what happens. If I create a new project, I can normally (but not 100% of the time) safely add a Kontakt instrument. I can build my project, but when I start laying down multiple tracks I risk Garageband crashing. The error messages always quote Kontakt (normally 7 and normally the VST3) as being the process leading to the crash. Typically the crashes take place when I select a Kontakt instrument and try and open the Kontakt (or Komplete Kontrol) window to make changes. I get a beachball and then a crash report.
Both Kontakt and Komplete Kontrol run well in standalone mode.
I have done complete reinstalls of Garageband and Kontakt, Komplete Kontrol.
I have even set up a bash script to do some of the tidying more efficiently.
Loading Garageband without Core Audio (holding down left ctrl on load) occasionally helps....especially if I am in a crash loop, as sometimes the crash report's "reopen" window leads to another crash.
I'm happy to submit crash report details....I have plenty!
Any ideas on a fix?
