Error: Photoshop could not save file because write access was not granted
When saving file, file dialog box view does not matter(ie list, icons, column), what does mater is Finder itself. What does this mean?
Ok so open finder and change the view from column to any other(list or icon). There is no need to disable any icon preview in finder options. After that you can now save files normally in PS.
Validated: tested and works fine with PSe(Photoshop Elements)
