LrC crashing when importing files

[markhallam74]

Hi, I am new to the community. I have recently bought a new iMac and have the latest updates for LrC installed. Every time I try to import it crashed after only 2 photos! I've disabled the GPU, reset preferences, purged the cache and tried a new catalog. I have plenty of space on my external hard drive and using the same SD cards I've been using for a while now. I've tried two different SD cards and have the same issue.

I never had any issues with my 10 year old MacBook!! 

please, does anyone know how to fix this? 

thanks

Mark

Have you enabled all the Apple required write permissions?  Can you try copying some files from your SD card to your drive and then try Importing?

Please tell us the version NUMBER of Lightroom Classic (we need the version NUMBER and not words like "latest" or "up-to-date").

Please tell us the version NUMBER of your operating system (we need the version NUMBER and not words like "latest" or "up-to-date").

When the crash happens, is it just LrC that crashes, or does the entire computer crash and require a restart?
