After opening a small handful of Sony ARW files in ACR, loaded and displayed correctly, ACR crashes.
Today I selected all four ARW files and zoomed to 100% which resulted in dozens of ACR panels being generated behind the main ACR panel. The Macbook pro locked up again, totally unresponsive the only option was to power down.
I have been using Photoshop since the late 90’s and have never experienced this behaviour before.
Edit facility here is not working on either of my computers hence additional information.
I donlt suspect that my graphics card is an issue, it was replaced last year after an Apple recall. I have no issues with Lightroom dealing with large numbers of RAW files, Nikon, Canon or Sony RAW files. The issue with ACR only developed after recent Photoshop 2021 updates.
