Frequently Asked Questions
Why does the Acrobat Pro 2020 activation window go completely blank?
This issue typically occurs due to outdated software builds being incompatible with the rendering engine of newer operating systems like macOS Big Sur, or due to corrupted licensing cache files in the Adobe OOBE directory.
How do I access the hidden Library folder on macOS Big Sur?
Open Finder, click 'Go' in the top menu bar, and hold down the 'Option' (Alt) key on your keyboard. The 'Library' option will appear in the drop-down menu for you to select.
