Synchronized settings don't "stick" during tethering

Report · Oct 16, 2025

This issue is driving me a little crazy and I'm not sure where the blame lies—when tethering LR Classic (14.5.1) with my Canon R5 on my Macbook Pro (M1 max, 64gb ram, macOS Sequoia 15.6.1), I rely on adjustments I make to an image to 'carry over' to the next imported shot so I can compare frames. For example, I will take a shot with the laptop, adjust the exposure, use transform and crop tools to give the photo an initial edit. Then I was adjust my exposure or change my flash settings or whatever then take another frame... The edits made to the previous frame do mostly carry over, but if I go back and fourth from the prior frame to the latest, often the newer frame gets reset. Then, when I select the two frames and sync the prior frame's settings again using the button, it frequently fails and I have to do this a few times to get the edits to 'stick'. This issue only occurs when I'm tethering—syncing settings works fine during non-tethering edting.

I work with another photographer who uses the Fujifilm GFX platform (there's a separate plugin for those cameras to tether into Lightroom) and I have never seen this same issue when performing the same workflow, using mostly the same tools (M1 Pro Macbook Pro), so I know I'm not trying to do something the software isn't designed to do.

This is difficult to search for—has anyone else had this issue or have any solutions?

Hi @ColinJR, thanks so much for reaching out!
Has tethering worked for you in a previous version of Lightroom Classic or macOS, or has this issue been there since you started using tethering?
As a first step, it might help to reset your Lightroom Classic preferences. Here’s a quick guide on how to do that:

This issue is not new to me, but I can't say how long it's been going on... I will try resetting preferences but because I'm in the middle of a project I don't want to do that until I have time to record all the prefs I use and go down that rabbit hole.
