You can try out each MacKeeper feature once for free.
Thanks to MacKeeper’s antivirus protection, you can scan your Mac for malware in seconds. Opening PDFs from unknown sources is potentially dangerous. While PDF documents are supposed to be final, you can make some changes, whether it’s highlighting errors, adding signatures, or redacting sections of text. PDFs allow you to share a read-only version of your document, displaying the same formatting and layout on any device and in any software used to open it. To get around this, you could save your document as a PDF (Portable Document Format) file to share instead.
You’ve just written a document on your Mac and you want to share it, but you’re worried about changes to your document by others.
