IF Mac El Capitan read below
CS6 and earlier programs have not been tested and will not be updated to run on Mac El Capitan
-which means that you try to use CS6 and earlier at YOUR risk of having problems
-you may get CS6 and earlier programs to install and run, or you may not (some do, some don't)
Install CS5 on Mac 10.11 https://forums.adobe.com/thread/2003455 may help (also for other than CS5)

MacOS Sierra has not yet been released in its final version.
I presume you mean your new MacBook Pro is running OS X 10.11 El Capitan?
I am running MacOS Sierra Beta
OK, so you're on an unsupported, yet-to-be-released OS.
Try changing your security settings:
- Click on the Apple icon in the top left corner of your screen and choose System Preferences.
- Next, click on Security & Privacy icon.
- To edit the security settings, click the padlock icon in the bottom left of the window.
- You will be asked to confirm your Mac credentials, enter them and hit Unlock.
- On the following screen, you'll see the options for "Allow applications downloaded from", you need to click on the "Anywhere" radio button, once you click that you will see a confirmation window, click on "Allow From Anywhere".
I did this already and even disabled gatekeeper from the command line
sudo spctl --master-disable

I figured it out, here is the solution:
Right click on the app and go to 'Show Package Contents'
Navigate to 'Contents/MacOS' and open that folder in Terminal
In terminal run: sudo ./Install
When I try to do this it says "Install" can't be opened, You should move it to the Trash.
I got the same. Help???
Same problem here, I've downloaded 4 times ands can't install, going crazy!
This worked! Thank you!
OMG, thank you so much for finding this answer utilizing Terminal! I've been having problems with my programs for WEEKS! Something went wrong and none of them would open. I followed a million different answers without being able to fix the problem, including trying to uninstall and reinstall, which kept bringing me to this same error message. I finally came across this answer and it WORKED! THANK YOU!
Thanks so much, Vol4life!
I've been messing with this for days, trying to reload CS5.5 onto my "vintage" MacBook Pro after restoring it. The instructions on the page you linked (including the tip on how to open the terminal) worked like a charm!
