Hi Michael, my name is ***** ***** I would more than happy to help you with your question.
Can you let me know if you are using Photoshop on full screen mode? This is accomplished by clicking on the green button on the top left corner of the application. To easily see if you are in the full screen mode, just check your toolbar. If you can't currently see the buttons to close or minimize the application than it means you are in full screen mode
Would you like to do a quick remote screen sharing session to move things along faster? This will help me see what you are seeing on your screen, which in turn will help me assist you better.
Please give me a minute for me to start the remote session, and we can go on from there.
You can use this link to join our remote screen sharing session. http://www.justanswer.com/remotedesktop/join.aspx?Session=8a2c16cc-2a79-4bec-b99a-9e93beaafe6e&Type=Java
To by-pass this you will need to open up System Preferences, go into Security & Privacy section. Once you are there, you will see an option saying "Open Anyway" which will allow the installation to continue for this once.
This allows you to download programs that you actually trust, but your Macbook is not familiar with.
When you get the chance, please let me know if you were able to start the installation or not. If you are having trouble with the installation, we can always do it without the remote session, it might just be more difficult to asses the full situation.
Would you like me to try and resolve the installation issues, or continue without the screen sharing?
To clarify, is that a "yes" to continue without the screen sharing?
OK no worries! Before we continue, please make sure to save your work on Photoshop if you have any open projects. Once it's saved, please let me know and I can continue.
Alright! So, let's first make sure that you have extended display enabled on your Mac. To do this just follow these steps:
Yes, I did see that message as well. If these steps resolve our issue, we will not need to install Java, as that was only for screen sharing software we use at JustAnswer.com
So when you are in the "Arrangement" setting, do you see an option towards the bottom of the page that reads "Mirror Displays"?
It should be right under where you see those monitor images
Is the checkbox next to "Mirror Displays" checked or unchecked?
OK, that is good. Now in the monitor images, can you let me know how the smaller computer screen is placed as compared to the bigger screen? Is the smaller screen on the left/right/above/below of the bigger one?
OK, that helps us as well. Now, can you click anywhere on your MacBook screen and let me know what the gray toolbar reads?
Is your MacBook screen still black as you mentioned in the beginning, with just the gray toolbar reading Photoshop?
OK, this helps as well. Now let's try this. Click anywhere on the black area of your MacBook screen and on your keyboard press the following combination: Control + Command + F
Let me know if this changes anything on your screen.
I did not get the photo unfortunately.
Let's try this now, again on your MacBook screen, where you see the gray toolbar that says Photoshop, there should be an option that reads "View". Once you click "View" all the way at the bottom, there is an option that either reads "Enter Full Screen" or "Exit Full Screen". Can you let me know if it says Enter or Exit?
No problem Michael! It looks like this is a situation that I have not encountered before based on your answers, so I am going to opt-out to allow a more senior expert to jump in and help you, is that OK?
