If you're using current software from 2020 or 2021, your new computer should not pose any problems. However, older software isn't compatible with Apple's latest operating systems: Catalina & Big Sur.
1. Use a Mac user profile with full administrative permissions to install software.
2. Log-in to Creative Cloud.
3. Download and Install Creative Cloud Desktop app followed by Photoshop, Lightroom, etc...
4. Restart your computer.
Post back if you have more questions.
