First: The message about the ray-traced 3D renderer is not an error. Read it carefully. It is just telling you about a feature that reiles on hardware that you don't have.
Regarding your other issues, see this:
If you need more help, then provide answers to all of the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
Regarding the link you posted my firewall is not enabled. The only codecs in my quicktime folder are AppleIntermediateCodec and AppleMPEG2Codec which I assume are 1st party not 3rd party?

Still encountering this problem, any other advice?
I am having the same messages and errors and take a very long time too boot. My firewall is off and there are no third party files in quicktime. is there any solution for this?
I've managed to fix this. (granted my fix means un-installing all of your Adobe programs but if you want a job done you got to break some eggs...)
After speaking to Adobe and Apple help I've found this out...
Quick way to test if its the same problem as mine would be to create a new account on your computer with admin privildges and load After Effects in that new account, it should load correctly. If it does, follow the steps below...
Ok so step by step...
1. Search for "Disk Utility" in spotlight.
2. In Disk Utility click on Macintosh HD.
3. Click "Verify Disk Permissions"
4. Once this is complete click "Repair Disk Permissions".
Make sure all Adobe applications are closed at this point.
1. Open a finder window.
2. Alt-click on "Go" at the top of the screen.
3. Click on Library.
4. Go to the "Preferences" folder.
5. Search 'Adobe' and make sure you select to only be searching in the "Preferences" folder.
6. Select ALL of the files and drag to the trash can.
7. Empty the trash can. (some might not delete at this point)
8. Uninstall ALL Adobe applications using their un-installers in the Applications folder. (make sure to tick remove preferences)
9. Uninstall Creative Cloud.
11. If some files would not delete before you should be able to delete them now.
13. Re-install Creative Cloud.
14. Re-install your prefered applications.
15. Boot After Effects and it should *cross fingers* work!
Please let me know if this works cause I'd love to know that I'd helped someone who was in my situation.
