Question

Could not complete the Color Halftone command because AppleTalk is not connected.

Hello All,

Today I experienced a strange error:

"Could not complete the Color Halftone command because AppleTalk is not connected."

Has anyone experienced this? My working theory is that it's because my image file is too large.

Thanks!

I'm using the 2025 version of Photoshop (26.4.1) on a Mac running Sonoma (14.7.3) and it's 5 years after this initial post and this "AppleTalk" error still exists.

And yes, as noted, it appears to be related to the size of the file. Smaller files do not experience this issue.

2 issues:

1) we need this to run on larger files because that's the size of the files we need it to run on (to the suggestion that it was unnecessary); and

2) how is a filter (that may be limited by the amount of data it's meant to run on) generating an error with anything related to AppleTalk, which no one has used in more than a decade, when it's not network-related?

I also received this "Appletalk" error. Cropping the image addressed the issue.

AppleTalk was discontinued in 2009. Which version of Photoshop are you running and whcih version of macOS.

For AppleTalk to work, you would have to be running macOS 10.6 or older.

Hi Warren,

Thanks for the reply!

I'm running Photoshop 21.0.1 and macOS 10.15.1.

It turns out there there does seem to be a size threshold factoring in to this. I got the error when using an image 28,800 x 18,000, but at 24,000 x 15,000, it worked. However, it would be great if it is possible to work at the larger dimensions.

That is a massive file size. What is the end point for this?

Normally when working on large format pieces you work at scale not actual size.

I create a workpath from the halftone raster that I export to Illustrator and send to a vinyl cutter. If I can work at higher resolutions, I get a smoother workpath.

Ultimately, its for making paintings, so I'm probably not the most logical user / use-case.
