[Plugin] Photoshop Crash

Topaz Gigapixel AI Bugs and Issues
1

Using the PS plugin, GP crashed both PS Beta and PS Current Release after upscaling from 1300 to 1920. Nothing special about the file (PSD can’t be attached) that I can tell. First GP crash in quite awhile but frustrating nonetheless.

Thanks

Just updated Gigapixel on my MacBook Pro and it crashes PS CC.

I’ve seen similar behavior crop up after plugin updates (in general)—especially on macOS where so much hinges on code signing, IPC, and how the OS interprets entitlements.

There are a few likely culprits worth considering:

  • Code signing mismatches
    If Gigapixel’s helper binaries were updated but Photoshop is still referencing the old ones, macOS might block or silently kill the plugin launch due to signature mismatch.

  • Memory hand-off instability
    Gigapixel afaik typically pulls raw layer data from Photoshop, and if you’re working with large smart objects or multi-channel files, that data exchange can break—especially if there’s a buffer alignment or image mode issue.

  • Rosetta translation confusion
    If Photoshop is running native on Apple Silicon but Gigapixel’s plugin is still Intel (or vice versa), you get weird cross-architecture IPC breakage. Seen this before with other plugins post-update.

  • Sandbox/permission regression
    (I think) Ventura and above tend to revoke previously granted accessibility or disk permissions after app updates. If Gigapixel loses full disk access or automation rights, plugin communication can fail outright.

That said, there’s so much variability here—macOS version, chip architecture, plugin install path, Photoshop’s own plugin manager—it’s near impossible to pinpoint root cause without the usual suspects:

  • Exact Photoshop + Gigapixel version
  • macOS version and chip (M1/M2/Intel)
  • Whether both apps crash or just Photoshop
  • What actually triggers it (plugin launch? layer transfer? post-processing?)

If it helps, running Gigapixel standalone and exporting manually from Photoshop can be a good sanity check to rule out deeper system-level conflicts.

But yeah—plugin architecture on macOS is still way more brittle than it should be (due to the OS being shit LOL) Would love to see Topaz bake in a better self-diagnostic layer for this sort of thing but that might require a magician we rarely see. (Again see reason above :joy:)
