Solved: CS6 on High Sierra

Hello,

Apple File System (APFS) introduced with High Sierra is faster and better for a SSD but not fully compatible with CS6.

Fortunately it's possible to install macOS High Sierra without APFS conversion:

1. Download macOS High Sierra from App Store.
2. After download is complete, the installer opens automatically. Leave the window.
3. Open Terminal (or from the Utilities screen menu options if booted from a USB boot installer) and paste:
   

   sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --converttoapfs NO

4. Hit return key.

This will force installer to bypass APFS conversion. High Sierra will run on HFS+.

I didn't find any errors so far!
