Beta 122: Batch processing issues in Photo Beta on Mac Posted September 11 Hi MEB, Thanks for your efforts thus far. I've looked into this a bit more and it may be dependant on my setup - I have AP installed on my (NVMe->adaptor->Mac Pro 2013) system drive and I'm batch-outputting images to an external (modern, fast, FAT-formatted) USB3 spinning disk. After error checking filesystems and updating OS 10.13.6 to the latest security update I can not currently reproduce the zero-byte file creation issue. Still testing to see if now all files are being written whenever I run a batch with parallel processing turned off and after that will check if parallel processing behaves. Perhaps it's an issue with AP not waiting around for a comparably slower output device during batch export? Testing it over a slow network might get some results, too. What I can rule out is that it only affects files of a certain format or image dimension/file size threshhold.
