Message about PDF

[Hosun]

Hi,

Sometimes, I encounter the message below. 
My work had nothing to do with pdf.

What is that?

If you are trying to open a PSD, use Adobe Photoshop instead of Apple Books and let us know if it opens there.

Jane

[Hosun]

Yes.

I opened Ai, Ps, Id, Apple Books.  

Hosun

[jane-e]

Yes.

"Yes" to what? Yes the file opens when you open the PSD in Photoshop? Or something else?

Jane

[Hosun]

Apple Books was opened with Ps. 
And a file was already opned in Ps. 

I think opening file doesn't call up that message.

I think it's enough to understand the cause of the problem. 

It does not look like a serious issue.

Hi @Hosun 

One more question, because I'm confused:

do you have Photoshop and if so, how is it involved with your PSD and Apple iBooks issue?

Jane

[Hosun]

Now, I learned my issue was related with Ps and Apple Books. I will find out in which situation the message comes out. 

So far, I had no clue about it.

Hi @Hosun 

Apple Books is an e-book reading application by Apple Inc. for its iOS, iPadOS and macOS operating systems and devices. https://www.apple.com/apple-books/

Adobe Photoshop is an image editing application.

I'm glad it's sorted for you now 😊
