Safely open apps on your Mac

macOS includes a technology called Gatekeeper, that’s designed to ensure that only trusted software runs on your Mac.

The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.

If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina and later also requires software to be notarized, so you can be confident that the software you run on your Mac doesn’t contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.

Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.

The warning messages displayed below are examples, and it’s possible that you could see a similar message that isn’t displayed here. Please use caution if you choose to install any software for which your Mac displays an alert.

View the app security settings on your Mac

By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.

In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”

Open a developer-signed or notarized app

If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.

An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected.

If you see a warning message and can’t install an app

If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can’t be opened because it was not downloaded from the App Store.*

If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer and—in macOS Catalina and later—notarized by Apple, you also see a warning that the app cannot be opened.

If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.

You may want to look for an updated version of the app in the App Store or look for an alternative app.

If macOS detects a malicious app

If macOS detects that software has malicious content or its authorization has been revoked for any reason, your Mac will notify you that the app will damage your computer. You should move this app to the Trash and check «Report malware to Apple to protect other users.»

If you want to open an app that hasn’t been notarized or is from an unidentified developer

Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.

If you still want to open an app for which the developer cannot be verified, open System Preferences.*

Go to Security & Privacy. Click the Open Anyway button in the General pane to confirm your intent to open or install the app.

The warning prompt reappears, and if you’re absolutely sure you want to open the app anyway, you can click Open.

The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.

Privacy protections

macOS has been designed to keep users and their data safe while respecting their privacy.

Gatekeeper performs online checks to verify if an app contains known malware and whether the developer’s signing certificate is revoked. We have never combined data from these checks with information about Apple users or their devices. We do not use data from these checks to learn what individual users are launching or running on their devices.

Notarization checks if the app contains known malware using an encrypted connection that is resilient to server failures.

These security checks have never included the user’s Apple ID or the identity of their device. To further protect privacy, we have stopped logging IP addresses associated with Developer ID certificate checks, and we will ensure that any collected IP addresses are removed from logs.

In addition, over the the next year we will introduce several changes to our security checks:

• A new encrypted protocol for Developer ID certificate revocation checks
• Strong protections against server failure
• A new preference for users to opt out of these security protections

* If you’re prompted to open the app in Finder and you’re sure you want to open it despite the warning, you can control-click the app, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.

there are currently no virus for OS X reported to be found «in the wild» from any credible securities lab in the world. At this time AV products for OS X have been found to be the cause of many problems with OS X from general sluggishness to system crashes to false positives to providing erroneous suggestions to end users that can exacerbate issues with OS X , but offering no benefit to the security of OS X.

and many of these products with «windows credibly» are making some shoddy crap for OS X. Microsoft.

Note that although JimmyCMPIT is technically correct, in that there is no known malware that can infect your Mac without you doing something to activate it and it won’t spread to others computers by itself (narrow definition of a virus), there are hundreds of other types of Malware currently in circulation capable of infecting it should you choose to download and install it. He wants you to use the term «Malware» which including computer viruses, worms, Trojan horses, ransomware, spyware, adware, scareware, and other malicious programs, but he never bothers to tell users that.

By far the largest majority of malware that can impact your Mac today is in the form of adware. It is designed to redirect your browser to another page, pop-up or pop-under a page or show underlines that pop-up ads when you hover over them. The adware developer gets paid every time such things happen. Although not particular harmful, it may well slow your computer experience and is annoying at best.

SiteSucker 17+

Rick Cranisky

Screenshots

Description

SiteSucker is a Macintosh application that automatically downloads Web sites from the Internet. It does this by asynchronously copying the site’s webpages, images, PDFs, style sheets, and other files to your local hard drive, duplicating the site’s directory structure.

SiteSucker can be used to make local copies of Web sites. By default, SiteSucker «localizes» the files it downloads, allowing you to browse a site offline, but it can also download sites without modification.

What’s New

Fixed a problem editing path settings.

Ratings and Reviews

Takes some tweaking

Ultimately, this app did what I wanted quickly and efficiently, though it took some wrestling with the configuration and reading the docs to get it right. Quickly and efficiently let me create local mirrors of

150 web pages, but getting it to hoover up the data I wanted and ONLY the data I wanted wasn’t straightforward.

That said, if you’re in the market for a tool like this, you’re probably used to fiddling with settings and such, and it certainly saved me enough time to justify the $5 price. I mean, you can do the same thing with httrack on the command line, but with 150 site URLs to paste in, why would you want to?

SiteSucker can be DANGEROUS.

I had to put my first download on «pause» because the «remaining» number kept getting higher and higher with no clue as to how long its growth would continue (When my computer was destroyed?)
I have written to the seller—twice—but have not yet received any reply, so here’s my final complaint.

Whoops! There are instructions. I just found them. Too bad I didn’t see them before I started doing my first download. I had to put it on «pause» because I was becoming very concerned that it was leading to the burnout of my computer. Well, now I’ll print a User Guide for myself. After studying it, I’ll go back to my first project. My question now is whether there is some kind of preview of things to come, like : Do I have enough memory for the job, or how much storage is required, or how long the download will take. You know, things like that. I’ll be restarring it when I learn how to use it in safety, safety for my computeer that is.

Underwhelming

My goal was to be able to download 2-3 levels of a website to use as a reference when internet connectivity or mobile devices were unsuitable or unavailable. Although SiteSucker pulled hundreds of files, it created an unintelligible mix of folders and files that could not be properly reviewed in a browser or via any other mechanism. Images were no longer embedded in any of the html files. Despite downloading with the default «localize» option, there was no usable html website representation that would allow me to use this properly (as might have been done years ago with Acrobat Pro). Overall, if all you want it to download the underlying files, the program works. If you want to be able to use it in html format as if the website was live — it doesn’t seem to support that. The help topic and FAQ did not reveal a mechanismm to move forward.
