I have a late 2014 27 inch IMAC, with 32 gig ram (3.0.4) and I am constantly getting the beachball and lockups with Catalina 10.15.6 editing JPEGs, did not seem to happen on the previous RAW Power, any suggestions. My HD is about half full.
I’m sorry that you are encountering issues with the current version on your iMac. RAW Power 3 does push the machine more than 2.0 did, especially the GPU. The amount of RAM and hard disk space should not be a factor.
Which GPU do you have? I may be able to suggest some ways to configure the app to reduce the load on the computer.
I just cleared the Dynamic Link Editor
“sudo update_dyld_shared_cache -force”
and to my surprise the program feels quicker and I get no dreaded beach ball or lock ups so far. I will see how it goes and let you know.
