I figured it out. I was trying to save to "Macintosh Hard Drive" icon. When instead I saved it to the "Documents" icon everything went fine.
[doublepost=1488711875][/doublepost]Out of curiosity, why won't it let me save to the Hard Drive icon?
Thank you. When I moved my files (including about 10,000 pictures) from my external hard drive it took about 3 to 4 hrs. Unfortunately I placed them on to the Hard Drive icon and hence my problem with trying to save "Pages". Thus, should I now move all my files from the Hard drive icon to "Documents"? Then, should I send to trash these same files from the Hard Drive icon?
did what Mike suggested and worked fine. I have 3 icons on my desktop-the icon of Macintosh HD, Lightroom and another photo app. The last two I downloaded from the internet. Are these just "aliases" such that I can drag them to the trash bin to clean up my desk top, without having to worry about altering the underlying files/applications?
One last thing. Now that my files are in the Documents folder is there a way to move or put an alias of the Documents folder on my desk top so I can quickly open it up?
