Did this work ok on previous versions of macOS? You only have 8GB of RAM and are using a LOT of virtual memory. Try restarting, closing all other applications, and maybe using a smaller catalog.

Yes it did, as a result I had to go back to the previous lightroom version

"MACOS 26"

 

So Tahoe. Could that new OS be part of the issue?

What happens when you try to export? Please describe in detail. If there is an error message, please quote the complete unedited word-for-word error message.

Hi there is no error message, it just says exporting but never actually starts, the export bar that shows progress just stays at '0' doesnt move, check screenshot

Thanks for the info! Are you exporting the files to an external drive or to a location on your computer's internal storage? 

Please ensure that Lightroom Classic has the necessary permissions on your Mac by following the steps mentioned here: https://adobe.ly/47rKHcn

If the app has the permissions, but you're still experiencing this behavior, try resetting the preferences of Lightroom using the steps mentioned here: https://adobe.ly/4otbfQE


Thanks,
Nikunj
