I have a Fujifilm digital camera that was compatible with my iMac 20. I have an IMac24 now but the CD from the camera with not load. So mt camera seems useless with this computer. An y help?

The application on the CD is likely a 32bit application, beginning with Mac OS Big Sur, Mac OS only runs 64 bit apps. Please contact Fuji to see if they have a 64 bit version of their app.

However the easiest method to use is to simply get a SD card reader, connect it to your iMac and upload your photos from the SD card to the iMac. If you use the Photos app this is extremely simple to do. Please refer to How to Import Pictures into Photos App in Mac OS X (osxdaily.com). While this article is old, it is still pertinent.
