MacOS Tahoe Adobe support - extremely poor performance

[defaultiekx62hn96eu]

I made the mistake of upgrading my Mac Studio to MacOS Tahoe, and now Premiere is practically impossible to use. Playback is choppy with the program choking on any timeline with more than one clip / effect, and simple edits have crazy input lag. I know how to revert back to Sequioa, but I don't have a Time Machine backup before Tahoe so it seems pointless.

Based on last year's Sequioa release, does anyone have an idea of when Adobe would release a patch to support the new MacOS? Will it be this year since they normally only release 5-6 updates and we're already at 25.5? Anyone else struggling with this and found any workarounds?

DON'T UPDATE YET IF YOU HAVEN'T

Hi, 

Thanks for the message and welcome to the forum. I have read that others are having similar issues. Can you try deleting the media cache? Press Shift at launch to get the Reset Options dialog box. There you can delete all the media cache. That may help. Let me know if it does. Sorry for the problem.

Thanks,

Kevin

Hi, yes I tried deleting my media cache already. Still running into the same issues.

Thanks for confirming that. The performance seems to be fine on Tahoe at my end. Would you mind confirming if this is happening with any specific media type/effect or all of them?

Any project using Insta360 / Action Cam footage is really struggling, even when those clips are disabled. But nromal H.264 and ProRes files are struggling in other projects that don't use Insta360 footage.

I'm on a 2022 Mac Studio - M1 Ultra 128 GB RAM

Thanks for the details. Is hardware accelerated decoding enabled under Premiere Pro > Settings > Media?

Having all the same issues with Premiere 25.3.0, even tried downloading v24, and v25.0 - nothing changes, they all have horrible performance now. Can confirm accelerated decoding is enabled as well as all my settings from before are unchanged. 

I have a few audio tracks and 2 video tracks for a 3 min video only in a rough cut stage. It lags and freezes constantly, if I try to ripple or roll any clips it hangs for a long time. It's extremely frustrating and borderline unusable. This has to be fixed asap.

Sumeet, thank you so much. This worked for me! 

I saw another reply saying otherwise, but Premiere's overall performance was immediately improved and back to normal.

My adobe premiere pro is now not opening at all. It tells me "Adobe premiere pro 2025 is damaged and can't be opened. You should move it to the trash" I have made sure all updates are done on my mac and my premiere. Ive tried deleting the app and installing an older version. I've tried holding down shift when launching. Nothing is working.
