(macOS M1 Max) Lightroom presets don't work/apply

Hi there,

Thanks for reaching out. We're sorry for the trouble with Lightroom Classic. We're here to help.

Could you please share the version of Lightroom & the operating system on your MBP(M1 Max)? Has this started to happen recently? Does this occur with a series of presets or specific images? What type of images do you work with? RAW or JPEG?

Where is the catalog & the original images stored? On the internal drive or an external drive? Have you tried any troubleshooting steps?

Do you notice any changes in the develop settings at all, or apart from the preset preview, there are no changes applied in the develop panels?

There are a few things you can try.

• If you are working on macOS 12, you need to follow the steps in this article to ensure Lightroom Classic has the required permissions: https://community.adobe.com/t5/lightroom-classic-discussions/quick-tips-how-to-give-full-disk-access-to-lightroom-classic-on-macos/td-p/12913413
• Go to Lightroom Classic > Preferences > Performance > Use Graphics Processor > Set it to 'OFF' if it is on Custom or Auto. If this shows you any differences in performance, please check this article to troubleshoot further:

• Create a new test preset with some basic adjustments, including some sliders with the maxed settings for a more visible effect & try to use that. 
• If you find only some presets behave like this, please share those presets with us via direct message.

Let us know how it goes,

Thanks!
