Kernel Panic on iMac

Jim Fisher
I am experiencing a kernel Panic with Capture One 20 on the exporting of image variants.

iMac Late 2015 21.5"
2.8 GHz Intel Core i5
8GB RAM
Intel Iris Pro Graphics 6200 1536 MB
High Sierra 10.13.16

Capture One 20 Build 13.0.0.186

I know this is the last update that will support High Sierra, I will be upgrading to Mojave.
Is this a documented issue? Capture One v12 was rock solid.

    More info:

    Seems to happen only when I am exporting copied negatives that I have reversed in Capture One. My regular photos export fine.

    This shows the image mods I did to achieve a positive image and my export settings.
    The photos live on a USB 3.0 external drive, if that matters.

    If the reversed adjustment (with the Levels tool, as I see from your screenshot) is the differentiating factor between proper operation and a kernel panic, I suggest you open a support case.

    By the way, I can not replicate the issue after inverting an image and processing it to JPEG or TIFF.

    Thank you for your speedy response. My thought is to upgrade to Mojave and see if the issue persists. If so, I will open a ticket.

    I have updated to Mojave and the issue persists. Now, instead of causing a system freeze or a kernel panic, Capture One simply crashes. Much more civil. 😉

    I have requested a support ticket be opened.

    All my other image variants export fine, it's just this latest set. Here's what makes this set different:
    - all other images in Catalog were from C1 v12
    - These are the only images I have added since upgrading to C1 20
    - I am reversing the levels to convert negative to positive
    - they were imported direct to C1 from SD card (normally I copy from SD card to external drive and then import to C1)

    That's all I can think of that is different.

    Same RAF files, saved to external drive and then imported to Capture One do fine with the Export Variants. The issue seems to be isolated to the direct import from the SD card via Capture One. May be something with how C1 is writing the files from the import?

    My experiences with Kernel Panics has always been a faulty memory module.

    Yeah, I remember that well in my G5 days!

    Kernel panics eliminated with upgrade to Mojave. Still have C1 20 crashes. Just tried to export a newly re-imported RAF file and C1 crashed. It is isolated to inverting the levels... on a LOT of images in a folder. Inverting the levels on a couple of images allowed exports. inverting levels on 20+ images caused a crash.
