Can't Save Photoshop Files on Shared Folders Through SMB
-
Problem - saving a PSD on a shared folder results in this error:
“Could not save because write access was not granted.”

Happens even with correct permissions.
The fix?
#Workflow

In Finder:
• Hide Preview when viewing files.
• Hide Preview -> ⇧ + ⌘ + P
Or...
• If Show Preview is enabled, de-select the file you’re working on in Finder before you save.

Also, in #Photoshop:
• Preferences -> File Handling -> File Saving Options -> Image Previews -> Never Save

Existing PSDs - may have to be re-saved without Image Preview, even when:
• Hide Preview is enabled in Finder, and/or...
• The PSD is deselected in Finder.
New PSDs - files saved with "Image Previews -> Never Save" can be opened and saved from a SMB share, as expected.

Image Preview Oddities:
• Even with "Image Previews -> Never Save" set in [Ps] prefs, a preview is *still* saved. You can see it in Finder. If the PSD's selected on the SMB share, and you try to save, you'll be denied. Deselect it, and save away. But...

• If "Image Previews -> Always Save" is set, some hard-coded value is written to the PSD. Any attempt to save is met with "write access was not granted.”, even if you deselect the file in Finder.
The Fix: set "Always Save" to "Never Save", then Save As... a new PSD.

Interestingly, saving another Adobe CC file, like an InDesign project, doesn't generate an image preview. Even when you ask for it (it's in the Save dialog, not buried in Preferences). Save an InDesign file and look for the preview in Finder. Nope.

But if you open an InDesign project from a SMB share, no problems saving.
So saving files with images previews in macOS over an SMB share will give you an error. @Adobe should address it. Developers write for the platform, not the other way around.

Of note: this doesn't happen over AFP shares. If your shared storage is on spinning platter drives, not solid state, you can stick with HFS+ volumes... for now. AFP's days are numbered with APFS.
