Cannot scroll through iMovie transitions on MacBook Air.

We are having the same problem. It just started recently. We also tried the advise given here, but it did not work.

I'm having the exact same problem. I updated to Sonoma 14.3.1 recently. Only one page of transitions in iMovie now and no way to scroll down to use the others. Such a bummer.

Sometimes with an upgrade iMovie transitions can go awry, that cause iMovie to behave improperly. Oftentimes this type of issue can be cured by deleting/resetting preferences. To delete/reset preferences close and then open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new empty library. Reopen your old library to get back to your projects. Now see if all of your transitions will display. Possibly you may need to reboot to set the changes.  Deleting preferences is a safe procedure that will not cause data loss or disruption to your project.

You can also try creating a new project and see if that cures the issue.

I don't know whether your iMovie app's failure to scroll the transitions is related to the upgrade. There have been some glitches related to the Sonoma upgrade, but I have not seen the scrolling issue reported on this forum.

In case it is related to Sonoma, make sure that you are upgraded to the very last update of Sonoma, as glitches often are ironed out with successive updates.

Try doing a Window/Revert to Original Layout and see if that cures it.

Try opening iMovie in a new or different library. Do that by opening iMovie while holding down the Option key and selecting to create or open a new library.

Another thing you can try is to open iMovie in your Mac's Guest account.

All else failing, try contacting Apple Support and talking to the techs there. They have the ability to remotely access your computer, that we do not have here.

Just went searching on the web to see if I could find any details on this exact issue and discoverd this thread from the last month. Have likewise deleted the app, reinstalled, etc. Nothing has worked. Also began experiencing the issue after the last update. The only workaround I have found is to position the cursor at the top of the timeline window (the bottom third of the screen) and condense the window down so that I can see all the transitions. I can then slide the window back up to its normal size. Not ideal, but sufficient for now.

I have a similar issue, the best remedy I've found is to drag the time line as far down as it will go and this lets you see all the options except the last four which are half covered. I was still able to select them though so it's better than nothing.

Having the same scrolling problem. Tried all the suggestions but nothing worked. I just gave up and don’t use the rest of the transitions
