I have upgraded to Tahoe…
Yes, I know, but. I need to find a solution or workaround simply because it’s impossible to write music.
Problem nature:
If I launch fresh, or load any track no problem with UI. Until I open or load any plugin. From that point I’m not able to control Pattern section by mouse. All other panel, like Pattern Order, Instruments or DSP’s has no issues.
Affected Pattern panel not reacting on any mouse action, neither clicks nor scrolls.
And because I can’t “activate” Pattern Panel I can’t even use keyboard to scroll, navigate or even edit.
See attached link to video (please ignore background washing machine sound).
I have just discovered even weirder behaviour. Renoise not only doesn’t respond on mouse within Pattern Section, it’s block all mouse activities system wide!
I can’t even navigate in Finder window.
Until I’ll close Renoise, this strange “blockage” activated across every OS window.
Please help.
I’ve found like a semi–workaround about this problem.
Workaround:
In case Pattern section unavailable to operate, I press “Fullscreen” green button and the section will be “unlocked”. Going back to window mode will lock it again. I need to repeat this after every plugin added or opened.
I’m 96% sure this is not a source of a problem. I think this is kind of glitch between rendering Renoise Plugin Server UI in new Mac OS Tahoe.
Tahoe was also fucked for me — not as bad as you have it, but my CPUs all ran 10-20 deg hotter in the same projects and I got DSP glitches much sooner as a function of plugin load.
Have reverted back to Sequoia tonight and all is as it should be.
I’ve found the solution, or good Workaround rather.
Problem:
After opening any plugin GUI (VST or AU) in Renoise on macOS 15 (Tahoe), the note input area becomes unresponsive.
Investigation:
• The issue occurs consistently after instantiating any plugin with a graphical interface.
• Reproduced across multiple plugin vendors and on clean macOS installations.
• Confirmed not related to audio drivers, controller scripts, or plugin sandboxing.
• Disabling transparency, motion smoothing, and window animations had no effect.
• Enabling Reduce Motion under System Settings → Accessibility → Motion immediately restores full input functionality.
Workaround:
Manually enable
System Settings → Accessibility → Motion → Reduce Motion = ON
This eliminates the freeze and restores normal operation.
(I’ve tried to create Automation however Automation of this setting via Shortcuts, shell scripts, or AppleScript is currently blocked by system-level security restrictions in macOS 15.)
I wanted to automate the process by switching Reduce Motion ON before Renoise launch via a script. However in Tahoe (MacOS 26) access to System Preference by AppleScript or shell script is blocked, unless you bypass the SIP or create MDM profile.
