STEMS feature causing audio lag and crackle after macOS Tahoe 26 update on MacBook Air M1
Hello,
I’m a DJ using a MacBook Air 13” (M1). After updating to macOS Tahoe 26, I’ve noticed severe performance issues when using the STEMS feature in Rekordbox.
Previously, on macOS Sequoia, everything worked smoothly, even with this resource-intensive feature. However, since the update, using STEMS causes high load — the audio starts to lag, stutter, and crackle.
You can hear an example of the issue in this recording: https://soundcloud.com/1tovmas/rekordbox-issue
I’d really appreciate any advice or possible fixes for this problem.
Thank you in advance for your help!
