I used to have an iMac 27 from 2011. There I used LL without jerks until October 2020. Since I bought a Mac mini 2020, it jerks in zoomed images. But only when I swipe with the Magic Mouse in the image. I bought an eGPU with the Mac Mini 2 months ago. Unfortunately, this jerking is not gone. The hardware acceleration should be configured correctly.
No problem, 10.1.1 (the same problem was with older version)
Have you checked with Adobe if your hardware, OS and Lightroom version are compatible together?
Yes, i write with the Support via Chat. The Adobe Supporter means my hardware was compatible.
Could you outline your image storage strategy for us?
The images are imported from a Canon 6D camera via SD card. This is done via LR to a network drive (NAS). I already use this system with the iMac 2011 and a 1:1 preview is created for the development of the images.
Are you using external devices?
The LR catalog is stored locally. But the images are stored on a NAS. I also have an eGPU connected.
