When opening a PDF lets stop relying on Adobe whether you are on a Windows computer or a Mac
First what is a PDF ?
PDF stands for “portable document format”. It was introduced to ease the sharing of documents between computers and across operating system platforms when you need to save files that cannot be modified but still need to be easily shared and printed.
Adobe for a long time has been the default software that people use to open PDF files
However if you want to open and annotate a PDF ( make a note on it ) , Edge the Windows 10 browser allows you to do this
On an Apple computer – stop using Adobe to open the PDF and try Preview – it comes with all Apple computers – Preview has some great features such as being able to reduce file size as well.
