Logic Pro 11 issues with Rosetta

I have the exact same issue. I heavily use Melodyne and Vocalign as ARA plugins, and now I can't because Logic Pro 11 doesn't support ARA and it won't open in Rosetta. I was excited for this update, and now I regret downloading it.

After 14 years, I realized that Apple does not value its customers just because it is a business

Trick: download the trial version of Logic Pro! It is currently still at 10.8.1 and it has NO restrictions besides a 90 day time limit. This should give you immediately 3 months of working under Rosetta and give Apple time to fix the issue.

I got some good news for all.

I reverted to 10.8.1 using Time Machine. Then somehow I discovered I could keep both versions on the same computer! Both will open without a glitch (although not simultaneously)

Moreover, the project files are compatible with both versions! No "Save as..." needed!

Now I have 10.8.1 with Rosetta on (for some older plugins, mainly orchestral samples)

Then 11 in Native mode (for most other work, and for the stem splitter 😝)

11.0.1 is out now. Rosetta working again!

I'm in the same boat. Logic updated automatically while I was in the middle of a session (I left my computer to walk my dog and when I came back it auto-closed and updated), and now just bounces and won't open in Rosetta. I use Melodyne and Vocalign heavily as well which is why I'm here.

Was supposed to deliver 6 tracks this week, this is a HUGE business stopper for me.

Please fix quickly or make it easy to transition back.

After several years of updates, I'm really sorry for Apple!!! Apple doesn't even know that its customers need Rosetta??? My main job is music and I have been working with Logic for several years. These last few years have really ruined Apple. My friends in Cubase have no problems. And I am forced to leave Apple and Logic forever. I'm really sorry. Really

Retrieve the old (working) Logic version from a backup. You can have several Logic versions in your Application folder as long as the older versions are renamed to something like Logic-10-8-1. The most recent version of Logic should not be renamed.

... and make sure auto-update is disabled now.

"I've been in Logic for so long that it makes it difficult to switch DAWs, but the lack of attention to detail and quality control has made me consider it.

To Apple, please do better. Logic is the host for many professional careers, and when there are mess ups this big, it just feels like a massive slap in the face."

I couldn't agree more with everything you are saying.

I am confused, I was told last year that Logic needs Rosetta to work!?

I am on Logic 10, on Rosetta, working fine, I wont be moving to Logic 11

Hi - The old 10.8.1 won't open because of Gatekeeper. Easy fix -- instead of double clicking the Logic Icon, Right Click or Control click it, THEN select open. It will prompt you if you really want to, then say yes. You should only need to do that once.

Rosetta is probably not a priority for Apple moving forward…

Most 3rd party developers offer native Apple silicon support, so if you’re relying on outdated plugins, I’m afraid it’s either time to upgrade, or ditch them for alternatives. (For those of a certain age, the transition from Power PC to Intel was equally painful)…

ARA compatibility is Logic specific rather than an Apple Silicon issue - due to Logic’s (now) reliance on “AUHostingService” which operates outside Logic & breaks ARA.

I’d much rather Apple concentrate on fixing ARA in Logic & Mac OS than fixing Rosetta. Seems Celemony & Synchro Arts are waiting on Apple rather than the other way around…

Basically, I have to choose: cancel all my ARA based plugins (Celemony and Vocallign), and remove Rosetta, or have a ten minutes break, everytime I open an old project.... So f..king frustrating. I will never recommend Logic to anyone anymore.

11.0.1 -> Sorry, ROSETTA isn't working well, maybe only for Logic Pro intern, but chrashes also with many good (updates) plugins (UVI, NATIV INSTRUMENT, MELODYNE, MAUDIO, IK SAMPLETANK, WAVETUNES et cetera). Every session Logic Pro send CHRASHREPORT. Whenn you open again the Plugins do not work oder sometimes a l'bit. Logic Pro run until now on Logic X Basis and NATIV with older Plugins. Melodyne say it is the DONT LIKE of Apple too implate correctly the "bridge" for there Plugin and others. Yes and this working Device is new with M3 and enought power et cetera, so i can't go back to older version.
