In the Preview app on your Mac, open the PDF you want to change. Do any of the following: Add a page to a PDF: Select the page you want to appear before the new page, choose Edit Insert, then choose Page from File or Blank Page. The new page is inserted after the current page. Delete a page from a PDF: Choose View Thumbnails or View Contact Sheet, select the page or pages to delete. I selected one of the PDFs which was set to open in Safari, did cmd-i (to get info) and then change the app to open with to Preview, and clicked apply to all. Now those 'broken' PDFs will open in Preview, but what's strange is, that in the Finder, they are shown as 'Preview documents' and not 'PDF documents'. In the Preview app on your Mac, click the Show Markup Toolbar button (if the Markup toolbar isn’t showing). Click the Sign button, position the pointer over the signature, then click the X to the right. The signature is deleted from all apps that use Markup on your Mac computer. If you have iCloud Drive turned on, the signature is also deleted from your other Mac computers that use iCloud.

- In the PDF menu, choose Save As Adobe PDF, and follow the onscreen instructions.
If you upgrade from Mac OS X Leopard (v10.5), Snow Leopard (v10.6), Lion (v10.7), or Mountain Lion (v10.8), the Adobe PDF Printer isn't removed.
The Save As Adobe PDF command appears in the PDF menu.

Add, they add a Save As Adobe PDF command. Customers using earlier versions of Adobe Acrobat in Snow Leopard cannot use the Adobe PDF Printer.
Technical changes in Mac OS X Snow Leopard (v10.6) and the later editions prevent Adobe from delivering a PostScript-based printer module. However, the new PDF workflow takes advantage of the PDF-based printing architecture already present in Mac OS X. By choosing Save As Adobe PDF from the PDF menu, Apple-based PDFs are converted to Adobe-quality PDFs using your JobOption settings.
The benefits of a PDF-to-PDF print workflow include the following:

- Better performance
- Higher-quality PDFs
- The ability to create PDFs that are compliant with Standards, such as PDF/X and PDF/A
- The potential for adding functionality to PDFs, such as bookmarks, hyperlinks and watermarks
Users of non-Adobe PostScript-based publishing applications cannot print directly to Adobe PDF, and must use another PDF creation method.
Some versions of some Adobe products, such as InDesign and Illustrator CS4 or CS5, don't support the PDF menu in the Mac OS X print dialog box. For those cases, either save as (Illustrator) or export (InDesign) to a PDF file. Or, print to PostScript® file and open that file with Distiller, Acrobat Professional, or Apple's Preview application.

Video Preview Not Working

Preview is the default app for opening and editing images and PDF files in macOS. It has several useful tools built into it. For instance, Preview offers a color palette in the Annotations Toolbar to allow users to highlight PDF documents in different colors. In short, Preview is a highly capable PDF utility and image editor that can help you annotate a variety of files, ranging from PDFs to JPGs.
The Preview app was changed a bit in High Sierra. As usual, most of the changes lean towards the positive side. However, there are a few changes that inconvenienced users. For instance, the right-click functionality in Preview no longer has an option for highlighting text. Sometimes it is also hard to open multiple PDFs files in a single Preview window. Perhaps the most troubling one is that annotations in PDFs and image files are crippled. Performing simple operations, such as adding a note or highlighting text, requires more clicking and mouse-pointing steps. In some cases, the entire color palette in the Annotations Toolbar is dimmed, so you can’t select any color. In fact, some users have found Preview highlight not working on High Sierra. Unfortunately, most of these users have no idea why the Mac Preview highlight is disabled.
It is frustrating that Preview on High Sierra isn’t better. But don’t get me wrong – I still believe that Preview is far more useful than most apps. That is why we developed this guide to help you resolve the Mac Preview highlight problem. In any case, we have all come across a bug or two while using different computer programs, and Preview is not an exception.
How to Fix the Mac Preview Highlight Problem?
Annotations are actually part of PDF standards, and most PDF readers, such as Adobe Acrobat, Foxit, and Preview, are cross-compatible with standard annotation and highlighting formats. So PDF-related inconsistencies could be ruled out in this case. To help you fix this issue, we will recommend some common troubleshooting steps for non-responsive Preview tools.
Step 1: Use Another Account for Testing
Before you try other troubleshooting steps, check whether the unexpected behavior is related to files or settings in your user account:
- Click on the Apple menu and choose System Preferences > Users & Groups.
- Click on the user icon and then enter a password and administrator name.
- Tap on the Add button (+) and complete the provided fields, then click OK.
- Ensure the documents you want to test are available to the new user account. You can drag them to the Shared folder.
- Remember to log out of your current account and log in with the new account details. If you are asked to sign in with your Apple ID or iCloud account, skip that step.
- Now try to use Preview in your new account. If Mac Preview highlight is disabled, then know that the issue is not related to settings or files in your user account.
Step 2: Restart Your Mac in Safe Mode
There could be something wrong with your Mac. To isolate issues with your computer, restart it in Safe Mode. Starting your Mac in Safe Mode will prevent some applications from automatically loading. It will also perform certain checks. Follow these simple instructions to boot your Mac in Safe Mode:
- Restart your Mac, then instantly press and hold the Shift key.
- Wait for the Apple logo to appear on your display.
- After that, release the Shift key and log in to your account.
- Your Mac will check and repair the startup disk directory, and then it will restart automatically.
Step 3: Update Preview to the Latest Version
Apple may have listened to the growing discontent about the problem of Preview highlight not working on High Sierra and released a fix to this issue. Therefore, updating your Preview to the latest version may resolve your problem and other common bugs.
Alternative Solutions
Sometimes Preview does not support editing of scanned PDF files. You can use an inexpensive third-party Optical Character Recognition (OCR) application to resolve this problem.
You can also highlight text using the line-drawing tool, but you need to set the color to a transparent yellow or simply choose a color of your choice and click on the ‘Show colors’ option to change the opacity for highlights to about 50 percent. For bigger fonts, select the thickest line to ensure that highlight covers the whole text.
Additional Tip: Check for and Repair Errors on Your Mac
Junk and corrupted computer files can make macOS misbehave. You should, therefore, scan for and repair bad sectors within your Mac. Viruses that target macOS are rare, but they exist.
Besides sluggish performance, one of the most cited symptoms of malware infections is misbehaving apps. You can avoid most Mac problems by using an intuitive repair tool such as Tweakbit MacRepair. This repair tool will pinpoint and remove infections within your system.
How to Highlight Files in Preview?
Highlighting text is usually an important task, yet most Mac users are still unsure about how to do it. Thankfully, you can use Preview to make highlights and other markup options. Please follow these steps to activate text in Preview:
- To highlight text in Preview, open the specific file using the app.
- With the file open, tap on the Tools option in the menu bar and then choose Annotate.
- From here, hit on the Highlight button and select the text you want to highlight.
- Repeat this process as necessary.
You can expedite this process by using the Markup Toolbar, which has shortcut icons for regular tasks, such as highlighting text. If your Markup Toolbar is not visible, tap on the View option in the Preview Title Bar and select Show Markup Toolbar.
Wrap-Up
Spend some time experimenting with a few tools in Preview. If you haven’t previously used the highlight option or other annotation capabilities, you will find the Annotation tool to be so helpful.
Preview is simple to use, and it is already built into your macOS, so there is no need to load or buy an expensive third-party app to open files or perform routine PDF editing tasks. Starcraft 2 heart of the swarm mission 14.
