PDFs won't open after updating to OS Big Sur
I had problems with my MacBook Air and rebooted the lot following Apple Support's advice (over the phone). Since then, I have been unable to open my PDFs; Word, XLS and other Office documents. I did buy the Office suite for Macs on the old version but do I need to purchase new ones?
What if I just want to read my pdfs and word documents etc?
MacBook Air 13″, macOS 10.13
