Hi everybody,

I just upgraded my mac from Catalina to Sequoia, time to clean my plugin selection and improve my workflow. All plugins that i want to use are fine only a few old ones not to important but DMG Equilibrium crash Logic like crazy. The plugin crash Logic 1 time of 3 when i close the window of Equilibirium and also at the loading of the projects. It's just my most used plugin :/. Anyone has a solution ?

Big thanks i advance for your help.

Hey there—sorry to hear about the headaches with Equilibrium; it's a killer EQ, so it's frustrating when it starts tanking your sessions like that. I dug around forums, Reddit, Apple discussions, and X for reports on DMG Equilibrium 1.68 specifically crashing Logic Pro 11.2.2 on Sequoia (noting that 15.7.2 seems like a custom or beta build—official releases top out around 15.6.x right now, but the core issues align with general Sequoia plugin woes). Your post on AudioSEX looks like the first public flag for this exact combo, so it might be an emerging compatibility hiccup post-upgrade from Catalina. No widespread DMG-specific threads popped up on their forums or elsewhere, but third-party plugins (especially older AU versions) are notorious for clashing with Sequoia's stricter security and AU validation.

Here's a step-by-step troubleshooting plan based on similar Logic/Sequoia crashes—start with the quick wins and escalate if needed. These have fixed 80% of comparable issues in community reports.

Quick Checks First

1. Update Everything:
   • macOS: Go to System Settings > General > Software Update. Grab the latest Sequoia patch (e.g., 15.6.1 or whatever's current)—many Logic crashes stem from early Sequoia betas and get patched in point releases. Users on 15.2–15.3 reported instant fixes just by updating.
   • Logic Pro: Open the App Store, search for Logic, and update to the absolute latest (11.2.2 should be solid, but confirm). If it's crashing on launch, download a fresh installer from Apple.
   • Equilibrium: Head to your DMG account at dmgplugins.com and check for updates. Version 1.68 is from 2022-ish; they might have a Sequoia-compatible patch by now (their site lists broad macOS support, but AU plugins can lag). If not, email [email protected] with your crash logs—they're responsive for workflow-critical stuff like this.
2. Reset Plugin Validation in Logic:
   • Open Logic > Preferences > Audio Units Manager (or Plug-in Manager in newer builds).
   • Find DMG Equilibrium in the list, select it, and hit Reset & Rescan Selection. This forces a clean validation—Sequoia broke a ton of AUs by being picky about code signing and entitlements.
   • If it fails validation, quarantine it temporarily: Uncheck "Enable All Plug-ins" and reload projects without Equilibrium inserted. Test a blank project with just the plugin to isolate.

Deeper Fixes for Persistent Crashes

1. Clear Caches and Prefs:
   • Quit Logic, then in Finder: Hold Option, Go > Library > Audio > Plug-Ins (delete any Equilibrium caches if present, but back up first).
   • Trash Logic's prefs: ~/Library/Preferences/com.apple.logic10.plist (restart Logic after).
   • For AU-specific junk: Run sudo killall -9 AudioComponentRegistrar in Terminal to flush the plugin registry, then rescan in Logic. This has saved sessions from "1-in-3" random closes like yours.
2. Isolate the Trigger:
   • Project Loading: Duplicate a crashing project (File > Save As), remove all Equilibrium instances, and reload. If stable, add them back one by one. Old Catalina projects often carry AU state that Sequoia hates.
   • Window Close Crashes: Try bypassing the GUI—insert Equilibrium on a track, but control it via automation or MIDI CC instead of opening the window. If that works, it's likely a graphics/UI thread issue (common in Sequoia with Metal changes).
   • Test in a new empty project: Bus a track through Equilibrium and bounce a loop. If it crashes there, it's pure plugin incompatibility.
3. System-Level Tweaks:
   • Grant permissions: System Settings > Privacy & Security > Full Disk Access—add Logic Pro and any DMG-related processes.
   • Disable SIP temporarily (boot to Recovery, csrutil disable) to test if it's a kernel extension block, but re-enable after—risky for production.
   • Rosetta check: If you're on Apple Silicon, right-click Equilibrium in Plug-in Manager > "Open in Rosetta" (or vice versa). Some AUs need it for legacy Intel code.

If Nothing Sticks

• Reinstall Equilibrium: Download a fresh copy from DMG, uninstall the old one (use their uninstaller or AppCleaner), and reinstall. Avoid copying from your old Catalina backup—Sequoia hates mismatched binaries.
• Downgrade Test: If you're adventurous, boot from a Sonoma Time Machine backup (pre-upgrade) to confirm it's Sequoia-specific. But yeah, that's disruptive for your workflow clean-up.
• Contact the Pros:
  • DMG Support: Attach your Logic crash log (Console app > Crash Reports > filter for Logic) when emailing—they can diagnose AU-specific faults.
  • Apple: Run Logic Pro Help > Open Crash Reports Folder and submit via Feedback Assistant, tagging "Audio Units" and "Sequoia."
  • Forums: Post your crash log on AudioSEX (yours is already there—bump it) or Reddit's r/LogicPro for crowd-sourced eyes.

Most folks with similar plugin crashes (e.g., UAD or iZotope on Sequoia) got sorted by updates or rescans, so odds are good it's fixable without ditching your fave EQ. If you share more deets (crash log snippet, Mac model, or if it's Intel/Silicon), I can refine this. Hang in there—let me know how it goes!

Big thanks for the clear post; helps narrow it down. What's your setup like (M1/M2/etc.)?

 

I checked everything. Cleared the cache, rescaned plugins... Equilibrium crash even when desactivated and if the project luckily load, clicking on it and closing it crash it 1 time out of 3 at least. I need to remove it entirely from the project to not having crashes on loading.

 

I really didn't expected that DMG plugins will causing me problems with the upgrade

 

If you ENABLE OpenGL, it has crashed my systems.
When I contacted Dave about it a year ago, he suggested I disable OpenGL. Solved my issue.

GLOBAL PREFS: OPENGL: DISABLE

Hope that helps.

If possible, check the Open GL setting in the Equilibirum preferences, in another app.

This option is not in the latest 1.68

 

Sorry @thunderfromthesky, wait for a mac User, i am a Windows User, cant help!

1. UPDATE Grafikcard OpenGL?

How do I check the OpenGL version on OSX?

glGetString(GL_VERSION)

Mac computers that use OpenCL and OpenGL graphics
https://support.apple.com/en-us/101525

2. OpenGL on Windows only, allows you to disable OpenGL in case there are compatibility issues with your machine. Toggling this option will require you to close and re-open the UI.

3. System Requirements -
Current version: v1.68
Mac OS EQuilibrium requires OSX 10.7 or better, on Intel mac. VST, VST3, AU and AAX are supported in both 32bit and 64bit hosts. RTAS is supported in 32bit ProTools 7 or newer.

I don't have it on OSX

From the manual :

OpenGL on Windows only, allows you to disable OpenGL in case there are compatibility issues with your machine. Toggling this option will require you to close and re-open the UI. VST Gestures allows you to stop the plugin from sending begin and end edit call

 

I gonna try to downgrade logic to 11.1.2

 

No probs anymore. Finger crossed but seems to work well

 

Arf, still bug when i close equilibrium but seems to be a little better. Don't crash anymore at the opening of the project.

What operating system is it?

Congratulations on the downgrade, but is that the solution to the problem?

You can also do the opposite: try an older version of DMG Equilibrium.
What kind of graphics card do they have, and have they checked if they can update OpenGL?

 

I have an intel mac. Never had any problems with DMG plugins on Catalina. But on Sequoia, after more investigations and tests, a few plugins from DMG are crashing logic when i close the window of the plugin. Trackcomp, Tracklimit, Limitless, Multiplicity. The only one that seems to work well is compassion. On ableton no problem with the plugins...
It's look like I'm the first to ask about on the internet. A lot had and still has some problems with the last Logic versions...

I'm sorry to hear about the frustration with those DMG Audio plugins in Logic Pro on Sequoia—it's especially annoying when they work fine in Ableton and on your older Catalina setup. You're not entirely alone in this; while exact matches for TrackComp, TrackLimit, Limitless, and Multiplicity crashing specifically on window close are scarce (likely because DMG's user base is niche and Sequoia/Logic 11 compatibility testing is still evolving), there are broader reports of DMG plugins (like Equilibrium) causing instability in Logic 11+ on Sequoia, including crashes during scans or UI interactions. Intel Macs like yours can amplify these issues due to how Sequoia handles older or non-optimized Audio Units (AUs), even if the plugins are universal binaries. Compassion working fine suggests it's better optimized, but the others might have lingering Rosetta-related quirks or UI bugs in Logic's AU host.

Here's a step-by-step troubleshooting plan based on common fixes for AU crashes in this combo (drawn from Apple forums, Reddit threads, and plugin dev notes). Start with the quickest ones and escalate if needed. These have resolved similar "unstable AU" errors for many users.

Quick Checks and Resets

1. Update Everything:
   • DMG Audio has released Sequoia-specific fixes for some plugins, including Multiplicity (VST3 metering/processing bug on Sequoia) and general AU stability. Head to the DMG Audio site (dmgaudio.com), log in, and download the latest versions for TrackComp 2, TrackLimit, Limitless, and Multiplicity. Reinstall them over your current ones—don't forget to deactivate/rescan in Logic afterward.
   • Confirm Logic Pro is on 11.0.1 or later (11.1+ has AU hosting improvements). Check for Sequoia updates too (15.1+ patched some Intel AU issues).
2. Reset AU Cache and Validation:
   • Close Logic, then go to ~/Library/Caches/AudioUnitCache/ (use Finder > Go > Go to Folder), trash the com.apple.audiounits.cache file, and empty the Trash.
   • Relaunch Logic while holding Control key—this boots in "safe mode" without AUs. If it opens fine, quit and relaunch normally; it'll rescan all plugins (this can take 10-20 mins but often fixes corrupted AU states).
   • In Logic: Go to Logic Pro > Settings > Audio Units > Reset & Rescan. If any DMG plugins fail validation, disable them individually via Plug-in Manager (under the same menu).
3. Test in Rosetta Mode (Intel-Specific Fix):
   • Right-click Logic Pro in Applications > Get Info > check "Open using Rosetta." Relaunch and test the plugins. This forces x86 emulation, which has stabilized crashing AUs on Intel hardware for many (e.g., similar DMG issues). If it works, the issue is native ARM handling—report it to DMG for a patch. (Downside: Slight CPU overhead, but negligible for mixing.)

Isolate the Problem

1. Targeted Testing:
   • Create a new empty project in Logic. Add one audio track, insert one problematic plugin (e.g., TrackComp), play some audio, open/close the UI 5-10 times. Repeat for each (TrackLimit, etc.). If it crashes consistently on close, note the exact step.
   • Try the VST3 versions if available (DMG supports them)—some Sequoia users report AUs are flakier than VSTs in Logic. Load via Settings > Audio Units > Plug-in Manager and rescan.
   • Check Console.app (Spotlight search it) for crash logs during the failure—filter for "Logic" or "AUHostingServiceXPC." Look for mentions of "DMG" or "abort trap." This can pinpoint if it's a UI deallocation bug.
2. Workarounds for Workflow:
   • Bounce to Audio: For tracks with these plugins, freeze/flatten or bounce in place (Track > Bounce in Place) before closing the UI—this bypasses live AU calls.
   • Disable on Close: In the plugin window, avoid resizing or rapid UI toggles. Some users script a macro (via Keyboard Maestro) to bypass the close button.
   • Since Ableton works, consider routing audio through Ableton as a ReWire slave or via IAC bus for mixing those tracks, then import stems back to Logic.
   • If overloads compound it, increase buffer size in Settings > Audio > I/O Buffer Size to 512+ samples during tests.

Next Steps If No Luck

• Contact DMG Support: Email [email protected] with your setup (Intel Mac model, Sequoia version, Logic version, exact crash steps, and a Console log). They're responsive and have patched Sequoia issues before—mention Compassion works as a control case.
• Apple/DMG Forums: Post on Logic Pro Help forums or AudioSEX (they have a DMG thread with Sequoia crashes). Reddit's r/LogicPro or r/Logic_Studio often has DAW pros chiming in with edge-case fixes.
• Rollback Option: If deadlines loom, boot from your Catalina Time Machine backup (or create one now) for those sessions. Sequoia on Intel isn't fully mature for pro audio yet—many hold off until 15.2+.

This should get you stable—let me know how the resets go or if you grab a crash log, and I can dig deeper. Hang in there; these gremlins are fixable.

 

I don't see any update on the website. the version to dl is the same than mines. So after further investigations and crash tests, I think it's an GUI bug. if i run the plugins without the gui it's seems to work fine. I tried also on Logic 10.8.1 and the same bugs are happening. So it's surely the way the OS handle the visuals with Logic that is the problem because on Ableton or thru Patchwork seems to run fine, but I wanted to get rid of this kind of Workflow after a Nebula period.

 

See if you have folder: /Users/YOURUSERNAME/Library/Application Support/DMGAudio/EQuilibrium/

If you do not, create it. You will getting the settings Wizard when you open it, because it cannot save its file and it does not create those folders for you. You could have done it manually when you were still on Catalina. That could maybe be causing your crash, trying to save to non-existent location. Only guess I have, otherwise GPU sounds like a good suspect.

 

Yes, the folder where the license is ? I have already done that and also on the presets folders.
I gave full access of the discs to logic, had some hope but arranging nothing.
The only ones that are not buggy are pitchfunk and compassion. The both share the same layout, so it's something to do with the compatibility of the new layout of the DMG suite and Sequoia and Logic. Ableton the plugins seems to be rock solid.

Check your mailbox!

 

the presets folder is in your normal system library. The one which will cause an error that results in the wizard opening every time is in the user ~library. 1.68 does not create the folders I mentioned on Catalina. Once you create that folder, and the one inside it, the wizard stops appearing each time you launch the plugin. If it is already there, the plugin should load normally. If it isn't, it will say your work is not saved after doing the setup wizard.

 

I have no probs with the wizard the settings can be saved. It's when i close the plugins 1 time out of 3 it crash logic. It's happen more when i'm in the settings of the plugins and close the window directly of the instance.
