In recent software updates, Apple has included more stringent security measures in its OS with the goal of better protecting your Mac from malware. While this gives you an added layer of protection, it also makes it more difficult to open applications that Apple is not familiar with (such as those not in the App Store or those created by unidentified developers).
While it may be tricky, opening these apps is possible. Here, we’ll explain the reasoning behind Apple’s enhanced security, show you how to allow any and all apps on your Mac, and even briefly discuss keeping yourself safe from malware.
Access /Applications in Finder and find the app, right click the app icon, choose Open menu item in pop-up right menu. Ever have a problem on your Mac, where you can’t type the letters and numbers 7, 8, 9, U, I, O, J, K, L, and M—and maybe some others? It’s probably Mouse Keys at play, an accessibility.
What does it mean to be able to download apps from anywhere?
- To add text using Preview app: Place your cursor where you want to insert text. Go to 'Tools,' click on 'Annotate,' select 'Text,' and start typing. To change the font, size, or color, go to 'View,' click on 'Show Markup Toolbar,' and press A.
- Click/tap on Advanced on the left side, and turn On (default) or Off Open sites in apps for what you want on the right side. (see screenshots below) While turned on, you can also click/tap on the Choose which sites open in apps button to turn on or off apps for websites.
- Obviously the address is a OS X/Unix type of address but it seems you can’t use it to access other protocols, i.e. Smb://ip/sharename, to open a file share or ftp://domain.com to browse a FTP destination.
Apple puts many safety measures in place in order to reduce users’ chances of being infected by viruses and other forms of malware. This is why Apple is known as a “closed platform”: It’s strict about what apps it allows to be easily downloaded onto and accessed from Apple devices.
The apps you can download onto an Apple device are generally limited to those that can be found in the App Store because they’re seen as more secure — they’re created by developers that Apple trusts and have been checked by Apple for malware.
In order to check an app’s safety, Apple uses a software called Gatekeeper.
Gatekeeper is Apple’s program that recognizes whether an app has been downloaded from the App Store. This program warns you when you’ve downloaded and attempted to run software from another location for the first time.
https://newfantastic147.weebly.com/blog/how-to-use-numbers-app-on-mac. Downloading apps from anywhere, then, means accessing and using apps that either:
- Don’t come from the App store
- Were created by unidentified developers
It’s a good idea to know how to download and access these kinds of applications. So many of the great apps out there simply aren’t available on the App Store. This is a crucial skill for those who rely on apps that aren’t necessarily meant for Macs (such as Microsoft software), as well as those who have recently begun using Apple devices and want to be able to use non-iOS/macOS apps.
Luckily, your Mac does allow you to download apps from anywhere — it just requires a few more steps.
How to download apps that aren’t on the App Store or come from unidentified developers
There are two main ways to give your Mac access to a broader range of apps:
- Set your Mac to allow you to open apps that aren’t from the App Store
- Set your Mac to allow apps from unidentified developers
Both of these methods consist of changing your Mac’s Security & Privacy settings to allow you to open apps that haven’t been checked by Gatekeeper. Once you’ve bypassed Gatekeeper, you’ll be able to download and run all the apps you’d like. (To learn how to do this, check out our piece on how to open apps from unidentified developers.)
How to download apps from anywhere
Before macOS Sierra, it was much easier to set your Mac to allow you to download apps from anywhere. You’d simply go to System Preferences > Security & Privacy > General, then under Allow apps to be downloaded from, select Anywhere.
Since new updates to macOs, however, you’ll need to change a few more settings on your Mac in order to do so. Here’s how:
- Launch Terminal by going to Finder > Applications > Utilities or by locating it with Spotlight search (
[CMD] + [SPACE]
). - In Terminal, type the code
sudo spctl --master-disable
and hit Return. Enter your Mac’s password when prompted. - Go to System Preferences > Security & Privacy > General. At the bottom of the window, you’ll see multiple options under Allow apps to be downloaded from. Select Anywhere to allow your Mac to download any and all apps.
If you later decide that you’d like to return to your Mac’s default settings and no longer allow apps to be downloaded from anywhere, just follow these steps:
- Launch Terminal.
- Once it’s running, enter the code
sudo spctl --master-enable
You’ll no longer be able to select Anywhere.
After this is done, you will only be allowed to download apps from the App Store, unless you use the steps mentioned above to access apps from other locations.
How to open Mac apps bypassing Gatekeeper
There is another way to open restricted apps that many Mac users don’t know about.
- Open your Applications directory.
- Click Finder > Go > Applications.
- Now, Control + click on an app you’d like to open.
This way you can open apps no matter where they come from.
How many suspicious apps do you have?
You probably have downloaded apps from all kinds of sources. Some of them (especially, the dubious ones) may install additional components on top of their main functionality. Chances are, you wouldn’t even know.
Such invisible applications are sometimes called launch agents or daemons. They may stay in the background for years. Probably, you have a couple of those lurking on your Mac.
How to check your Mac for hidden background apps
To check it, you can run a free version of CleanMyMac X
CleanMyMac X itself comes from MacPaw, which is a popular Mac developer and its apps are notarized by Apple.
- So, download and install a free version of CleanMyMac X.
- Click on Optimization and choose Launch Agents
You’ll see background apps you can disable in one click.
- In the same app, click on Malware Removal.
When it comes to finding suspicious apps and adware trojans, CleanMyMac X is way ahead of many other antiviruses.
CleanMyMac X will check your computer for all potentially unwanted apps (PUA) and all kinds of malware. It also helps you keep track of malware regularly with a real-time malware monitor.
A free version of CleanMyMac X is available here.
Is it safe to download apps from anywhere?
There’s no guarantee that apps downloaded from outside of the App Store will be safe. As these apps haven’t been vetted for security by Apple, it’s more difficult to confirm whether they’re safe and free of malware.
Because of this, you should be wary in changing your settings to allow apps downloaded from anywhere. Doing so leaves your Mac vulnerable malware and malicious software, as Gatekeeper won’t be able to check if the app downloaded is legitimate (or just malware disguised as the desired software).
The safety of your Mac, then, is in your hands. The best you can do to try to make sure that an app is safe to download is to look into its reviews and the experiences other users have had. Doing your due diligence can help you avoid using untrustworthy apps.
Downloading anti-virus software is another means of protection, as this software will check whether an app is safe for you. If, when researching all you can about an app, you decide you’d rather not download it, you can opt for a similar app with better reviews or one that is already in the App Store.
Get PDF editor with OCR
PDFpen lets you change anything about your PDF docs.
You can't escape them — PDFs are everywhere, especially in the workplace. Although convenient to read, PDFs can be tricky to deal with if you just need to make quick changes to the text, sign a form, or send a file through a size-restrictive platform.
With a default PDF reader like Preview on the Mac, finding a certain word in the PDF is difficult and editing a document can be almost out of the question. Without knowing which tools to use, it will be very hard to make changes to a PDF document. Fortunately, there are plenty of PDF apps to help you get the editing job done.
You can use PDF Search to search for specific document, information, facts, or figures. This would come in particularly handy if your PDFs are very long. To pore through your PDF in batches or to scan through long files, open the app and type in a search word or phrase in the search bar. Even if you misspell a word, PDF Search's artificial intelligence feature will make an effort to understand what you mean and help you find exactly what you're looking for.
Tools to Edit PDF Documents
By now, if you don't know how to modify a PDF document, you may be left behind. Good news is taking control of your PDF files is not rocket science — whether they be for home or work, you just need the right set of tools in place to cover your everyday requirements.
To help you alter PDF documents, there are a few apps with such useful features as adding comments, filling and signing agreements for your business, removing sensitive information, and compressing large files to allow for easier sharing. Stop agonizing over how to edit PDFs and try a few of the powerful applications mentioned below. You may want to redact your PDF documents, like edit typos or add different images, but how do you go about doing so?
Grab the best PDF editor
A perfect toolkit that allows you to rotate, combine, highlight, annotate, and change anything about your PDF. Easy squeezy.
Apple provides every Mac with Preview, a free program that allows you to read and edit PDF files (add and highlight text, combine PDF documents and transfer pages from one PDF to another, add a signature and comments).
Edit and mark up PDFs with Preview
The experience of editing images with Preview is pretty intuitive. We've created a quick guidance for you to instantly find what you're looking for.
How to type on a PDF, add text and notes
Open the PDF in Preview and try to add text by clicking on the target text field. If it doesn't work, you'll have to add a new text or note field:
- Select Tools > Annotate > Text/Note.
- Click on the text/note box that appears in your document and start typing.
- Close the box by clicking outside it. You can move the note/text field anywhere via drag and drop.
- To customize fonts or color of text, select View > Show Markup Toolbar > A.
Highlight text in a PDF
To activate the highlight mode in Preview, select the Highlight button in the top right corner. Click on the down arrow next to the Highlight button to change color, or choose an option to underline or strikethrough.
When switched on, highlights will be applied to any text you click on. You can switch it off by clicking on the same Highlight button.
To view notes and highlights in the PDF, select View > Highlights and Notes.
Combine multiple PDFs
- To merge PDF files, open one PDF in Preview.
- Select View > Thumbnails to see the thumbnails of all pages.
- Click on Edit > Insert > Page from file and open another PDF.
- Choose destination and save the updated file as PDF.
Rotate, delete, rearrange pages, and renumber pages inside a PDF
You can cut pages out or change the order of pages in a few steps via thumbnails:
- Open a document in Preview.
- Navigate to View > Thumbnails.
- To rotate, click on a page thumbnail > Tools > Rotate Left or Right.
- To delete pages in a PDF, select thumbnail > Tools > Delete to remove a page from your PDF.
- Rearrange by dragging pages around in the sidebar.
To change page numbering, you can use PDFpen editor. When you open a file, go to Edit > Headers, Footers, Page numbers > Insert. From there, you can customize the position and format of page numbers as well as define a starting page.
Split PDF files
To separate pages in a scanned PDF, simply drag the page you want to remove from the thumbnails pane to desktop. If needed, you can combine those pages into a separate PDF file afterwards.
How to reduce PDF size
You can compress your PDF in Preview while exporting the doc. Once you're done with editing, select File > Export. Click on Quartz Filter to open the pop-up menu > Reduce File Size.
Apart from Preview, you can use a scanning application like Prizmo app to create easily searchable PDF files out of paper-based images like brochures, books, or posters. This app lets you scan and recognize any photo documents to make them editable. You can even take a photo of a physical document on your phone, and finish editing on your Mac.
To make corrections or rewrite some text within the original file with editable text blocks, try PDFpen. Also you can use it to highlight, draw, scribble on the document.
Edit any PDF on a Mac
To correct text with PDFpen:
- Open the desired PDF document within the application
- Highlight the text within the PDF and click Correct Text
- Erase the current text and type the desired changes
To insert and edit an image in PDF:
- Click on 'Insert' icon and choose an image you want to add
- Move and/or resize the image by dragging it around inside the PDF
- Double clicking an image lets you adjust it or add some effects
- You can also delete pictures and drop new ones
You can also edit images by converting them into PDFs with Prizmo. With powerful OCR, Prizmo app instantly captures text and makes it fluid and editable.
To create a PDF from an image with Prizmo, use the following steps:
- Click the plus icon in Prizmo
- Find your source in the drop-down menu
- Select an image that you'd like to convert to PDF and click Add
- Click Recognize in the top right corner or toggle Text mode in View.
- Editable text will appear on the right side of the window.
Add comments and annotations to a PDF
To help yourself with extra notes or annotations, you can add comments directly onto a PDF. Comments can be useful to readers when you want to provide extra information about certain parts of the document.
To add text using Preview app:
Mac Can't Type In Open App Keyboard
- Place your cursor where you want to insert text.
- Go to 'Tools,' click on 'Annotate,' select 'Text,' and start typing.
- To change the font, size, or color, go to 'View,' click on 'Show Markup Toolbar,' and press A.
- You also can move the text box anywhere on the document.
A regular PDF viewer app won't let you attach comments to specific areas on a PDF, so you need to use an editor like PDFpen to do that. This app allows to add comments to PDF files with highlights, sticky notes, a freehand drawing. Annotations are useful because you can embed them into the file without being too distracting for a reader. You can also use the markup tools to add shapes around important areas of the PDF and underline things to remember.
App Can't Be Opened Mac
To comment and make notes on PDF:
- Click on the Comment (cmd+8) or on the Notes (cmd+7) on the
- Tap on the area of the document where you want the comment or note to appear
- Type in the comment or note area field
- Drag the comment or note text box to the desired area on the document
Fill and sign PDF forms (e-sign)
Printing documents just to sign them and scan them back can be frustrating and time-consuming. Many of us don't even have printers anymore. But luckily with e-signatures, there's no need for all that.
Now you can easily add your signature to digital forms and documents in macOS. Whether you're looking to have a new client sign an agreement, a tenancy contract, or any other PDF form, e-signature will save you time (and ink).
To sign a document using PDFpen:
- Scan your signature and save it as an image file
- OR draw your signature right on a PDF with your trackpad, magic mouse, etc.
- Drag, resize and correct position the signature inside your PDF file.
To sign your PDF file with Preview app:
- Open the document you want to sign
- In main menu go to Tools > Annotate > Signature > Manage signatures
- To create signature tap to Click Here to Begin, draw your signature on the trackpad, press any key when finish, and then Done
- You can also scan your handwritten signature - write it on a piece of paper, hold to be visible to the camera, and Preview will draw a virtual signature.
- Choose the signature created to insert it into the document. Drag, resize and correct position of your sign like a regular image
Redact sensitive information from PDFs
Many of the PDF files on your computer may contain sensitive or personal information, leaving you at risk of becoming a victim to identity theft. For example, a PDF form could contain your tax information, credit card numbers, or other personal details that you don't want to share with third parties.
This is where PDF redaction comes in handy. Without an appropriate PDF editor like PDFpen, it can be very difficult to remove parts of the text you want to hide from a document. Redaction can remove a word or an entire line of text with a black box or empty white space.
Of course, if you don't want to use software to redact your PDF, you can always take a black marker to cross out any information from a printed sheet. To make your life easier, use the following steps to redact sensitive information.
Mac Can't Type In Open App Chrome
To redact an entire section of a document:
- Within PDFpen, click Tools and select the rectangle tool
- Select the area of the text you want to redact
- Click Format and Redact Text-Block
To redact selected text:
- Under Tools select Text Tools
- Select the text you want to redact
- Click Format and Redact Text – Block
Compress and share a PDF
If you don't have a strong or reliable internet connection, it can be hard to send large PDF files to friends or colleagues. In order to upload large PDF files onto the cloud, send via email, or add them into size-restricted forms, you'll need an app like PDF Squeezer to help you compress the PDF file while keeping the original quality. You can rest easy that this process won't convert your PDF into a ZIP file.
To shrink your PDF resumes, applications, or visa-related documents for the web, use the following steps:
- Open PDF Squeezer
- Drag the PDF file you want to compress into the 'Drop Your Files Here' section
- At the drop-down menu, select your preferred dpi and image quality
- Click Save
With a built-in feature to send your PDF files to friends, clients, or colleagues, it makes sharing your compressed documents super easy. Click Share to send your file via text, email, or other options.
