In this document I write about how to edit a PDF file using the built-in OS X preview app. But sometimes you need to add your signature to a PDF document. Well here is some good news – you can also sign a document right from within the preview app. Thanks to Bryson who pointed this out to me!
1. Firstly click the pen symbol as if you were going to edit the PDF file.
2. Then click the ‘create signature’ button.
3. Sign using the track pad or camera.
If you select “trackpad” you will be able to use the trackpad on your MacBook to sign your signature and the app will record your signature and keep it in preview for signing future PDFs.
If you select “Camera” you just need to sign your signature on a piece of paper in panel pencil and then hold it up in front of your computer’s camera. Preview will automatically adjust your signature and scan it.
Now you can just select your signature and preview will insert it into the PDF document when you need it.
Your signature will automatically be stored in preview so that you can use it in the future, but if you want it deleted for security purposes you can simply click on the cross on the right-hand side of your signature and it will delete it.
In OS X Apple have again changed the way that 2 pdf files merge in the free OSX Preview App. To Merge 2 pdf files in OS X Mojave you need to drag the thumbnails of one pdf file into the thumbnail view of the second pdf file. You can’t drag a pdf file directly from the desktop into the new thumbnail window or the files will not merge.
The “Create Booklet” PDF action stopped working when Mojave was released. It seems to be to do with Apple requiring an increased level of application signing. What this means is that the old version of Create Booklet (that was free) that I wrote about here no longer works. You need to download the new version from the Apple App Store. (It costs $20). I’m not sure if it’s worth $20 just to be able to make a booklet. It may be worth it to you. In my opinion it should be a feature that the built in OSX print driver can do. But for now I cannot find any free options to do this.
As I mentioned in this post Apple regularly change the way to merge a PDF document. Yet again it’s changed with High Sierra – for the better. Now when you drag a pdf onto the thumbnail window of an existing pdf the two documents will ALWAYS merge. This make it easier than ever to merge 2 pdf documents. Here’s how to merge 2 documents in High Sierra.
If you’ve ever been given a pdf file that you want to edit, or a pdf form that you need to complete and return electronically, you’ll realise that it’s not obvious how to edit a pdf file in OS X. You can make simple changes to a pdf file using the free built-in Preview App that comes free with OS X. Here’s how.
Apple’s built in pdf reader app called ‘Preview’ can merge 2 PDF files and edit PDF files. In macOS Sierra 10.12 all you need to do is drag the thumbnails that you want to merge from one PDF document to the other and then save the document.
Read on for some screenshots of what this looks like.
