I updated my OS to Tahoe 26.5 several days ago. Now, I'm developing a new macOS application under it.
What I notice about it is that it can take the application at several seconds to select a file or a folder with NSSavePanel, NSOpenPanel and .fileImporter. First, I thought it's just my application. But it's not. Preview acts the same. First, a progress wheel keeps rolling several seconds.
Then it will disappear, and you won't be able to select a folder for another several seconds.
Why do they make it more difficult to use every time they release a new OS version? Why don't Reviewers notice when they test it? Wait for 10 seconds or more just to select a file or a folder? It's disappointing. I wish I could go back to macOS 15.7.
Your questions aren’t really things I can answer. Forums is primarily focused on code-level questions, and given that this issue is affecting Apple apps like Preview, it’s clear that none of your code is involved.
My advice is that you file a bug about it, making sure to include a sysdiagnose log that you triggered during the delay.
Share and Enjoy
