How to fix SPORE if it's not working on Mac High Sierra.
Please note this fix might not work for all of you!
First I uninstalled the Spore game using the Origin Program (must be singed in to your account)
Once uninstalled restart your mac, Download the Origin app again. do not sign in to the website.
after you download the Origin program install it on your mac.
Sign in to your Origin account after you have installed the Origin App.
Download Spore game again. after you have downloaded Spore game again, DO NOT PLAY it yet. Again restart your mac.
Once you have restarted your mac open the Origin app and click on Spore and click Update. apply all the patches. then again restart your mac again.
Open the game and try to play, or login, or create or register your account.
If it doesn't allow you to click on the Star World to start your game force quit the game.
by holding down the Alt / Option Button & Command Button & ESC button.
Then click on and high light the Origin app in the Force Quit Application box. and then click Force Quit.
next click on Apple Icon Top left side of your screen
click on System Preferences
Click Displays Icon
You will see it says DISPLAY Resolution, Default for display.
Click on Scaled Click on 1280 x 720
While you have the Display window open try to open your game again and see if your able to try to play the game again.
if it works good, if not then Exit out of the game again and change the Display settings back to Default For Display
Close the Display Box, Close Origin App, Restart your computer again, and then open Origin, and start your game again.
If you done all the steps I have mentioned this should have fixed your game and allowed you to play it with out any problems.
