Mac Security | Mac News | Reference | History

macOS Catalina has continued to move much iOS functionality onto the Mac, including the ability to port iPadOS apps. iTunes is gone, replaced with Music, TV and Podcasts. iOS backup in now in Finder and Sidecar turns supported iPads into a secondary monitor.

The end of support for 32-bit apps in macOS 10.15 is probably most significant for legacy users more likely to be using 32-bit apps.

Mac hardware and macOS made the jump from 32 bits to 64 bits a long time ago, but Catalina will be the very first version of macOS that is totally unable to run 32-bit software. — iMore

Catalina will be the last version of macOS to use legacy system extensions. Most active vendors have already made this change, but it may require you to pay for an upgrade. An example of the warning:

Switching to a Mac

The Mac provides a stable platform for those that dislike the direction Microsoft has taken with Windows 10 or those that need to run both Windows and Mac on the same machine.

[T]here's a simple reason to buy a MacBook. They last twice as long. — ZDNet
A common misconception about Macintosh hardware is that it's more expensive than equivalent PC hardware. In fact, that's not true. If you compare spec-for-spec Mac hardware against the equivalent premiere PC hardware like the Microsoft SurfaceBook or the Lenovo ThinkPad X1 Carbon, you'll find that the pricing is similar. — ZDNet

High-end Mac laptops (e.g. the 15" MacBook Pro) can be quite pricey, but are aimed at those that need the extreme performance in a laptop. Apple's 2019 MacBook lineup: Which one to buy? (video)

The switch from Windows to OS X has really paid off for me from a reliability standpoint. Sure, the Mac ecosystem is far from perfect, and there are still plenty of annoyances to contend with, but I'm wasting a lot less time hand-holding systems these days. — ZDNet

The integration with iOS devices like the iPhone and iPad make it even more attractive if you run those devices. You can even run Windows on a Mac by using Boot Camp or on a virtual suite like Parallels.

Should you switch? Have a look at When replacing your Windows 7 PC: Should you switch to Windows 10 — or a Mac?

High end Windows-based ultrabooks are priced near (or even above) similarly equipped MacBooks and MacBook Pro machines. — ZDNet

There are online resources and books to help you in the transition.

Mac Security

You need to be running security (antivirus) software on your Mac.

The use of security software for Mac OS X should not fail due to false vanity. — AV-TEST

Once of the reasons people love Macs is because of its reputation for lacking security vulnerabilities compared to Windows.

Macs No Longer Secure

That is no longer true. Security threats to Apple devices and computers have significantly increased in the last few years.

The Malwarebytes researchers, however, concluded that what the 2019 threat landscape tells us as we move further into 2020, is that "it's time to take a good hard look at Mac security and finally get serious." — Forbes

With Increased Popularity Comes New Threats

With the increased popularity of Macs has come a new set of security threats (see sidebar).

Don't Be Part of the Problem

Verify any links sent via email before you click on them and be wary of websites or sudden warnings that “you're infected.” Know how your security software provides protection and alerts so you can identify fake warnings.

Be aware of what you're sharing on social media and how it could affect your security and privacy. Too many people post answers to common security questions.

Install Security Software

I strongly recommended that you install security protection onto your Mac.

You'll find a listing of Mac security software in the software section.

Macs are very reliable, but sometimes things go wrong.

Unresponsive Programs

Apple has a Force Quit option for programs that don't respond to a normal shutdown request. This should be your last resort option.


Storage Options

Traditionally, the only option for a hard drive was a spinning magnetic platter. Today, SSDs have changed that but you need to be aware of the risks and benefits of each choice.

Backing Up Your Mac

If your hard drive fails, you'll lose all your data and perhaps the information necessary to recover your computer. Backing up your Mac stores that information so that you can recover. You might want to read a bit about backups to fully understand the main concepts and risks.

Security Software

You need to be running security (antivirus) software on your Mac. The effectiveness of security programs varies. See this not all products as effective.

Many Mac OS X security products adversely affect system performance. These reviews may help you decide:


The recommendation is mainly based upon comparing the reviews and personal experience. I'm unlikely to recommend a product that causes your system to slow down considerably or which provides poor protection, but it is a balancing act. Here's some notes from the 2018 Tom's Guide reviews:

Kaspersky Internet Security offers both the lowest system impact and some of the best malware-detection rates recorded. It even provides extra security features, including parental controls and options to lock down your webcam and stop websites from tracking your browsing activity. If you're willing to pay to protect your Mac from malware, Kaspersky Internet Security is the best option available.
Avast Free Mac Security caught 99.9 percent of all malware, packs in a password manager, barely leaves a smudge on system impact and doesn't charge a dime. If only it caught 100 percent of malware, as Kaspersky did.
Bitdefender Antivirus for Mac is one of only a few solutions we tested that offers perfect malware detection. Further, its modern, streamlined interface places on-demand scans front and center. Last year's winner dropped from first place, though, because its system-impact scores didn't match the flawless marks posted by Kaspersky.
Norton Security Deluxe may offer excellent protection, but it charges more (after the first year) than its competitors do, without offering as many perks. Still, always-on-call customer support is a nice thing to have if anything ever goes awry.


OS X's built-in firewall provides only inbound protection. There is no outbound protection and provides no additional protection if you're behind a router.

  • Little Snitch provides both incoming and outgoing firewall protection and includes a network monitor.

Photo & Graphic Design

Affinity products are extremely powerful and very reasonably priced.

  • Affinity Photo (CA$69.99, no subscription) is professional photo editing software for the Mac. In the works for 5 years, it has an incredibly intuitive interface. System requirements.
  • Affinity Designer (CA$69.99, no subscription) is professional graphic design software for the Mac. Affinity Designer won the 2015 Apple Design Award, “honoring outstanding design and innovation.” System requirements.

Internet Software

Web Browsers

  • Safari Browser is the Mac OS X default web browser and supports the latest standards and features.
  • Firefox Browser is available for Mac OS X 10.2.x and later.
  • iCab Browser. This alternative browser for the Mac is highly customizable and includes image filtering, which eliminates banner ads.


  • Postbox (US$29.99 per year) may provide a Thunderbird alternative to those looking for something similar but with more features.
  • Spark for Teams US$7.99/month/team member adds the ability to share and discuss email with your teammates to Spark.
  • AirMail is a new mail client designed with performance and intuitive interaction in mind. Available for macOS (US$26.99) and iOS (US$4.99).


  • Interarchy professional Mac FTP (US$64.00). (Note: there was an expired certificate for the site when last viewed the download page.)
  • FileZilla (free) is the recommended FTP client for casual users.
  • FileZilla Pro (US$19.99) is a professional FTP/S, SFTP client for Windows, Mac OS X or Debian Linux. Heavily optimized for speed, it can also connect with many cloud servers.

Accounting Software

  • It includes modules such as cashbook, invoicing, receivables, payables, taxes and comprehensive financial reports.
  • The Desktop edition doesn't support multi-user capabilities. If you require multi-user access, you will need to sign up for Cloud edition and your data will be stored in the “cloud” rather than on your computer.


  • VLC media player is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols.

LibreOffice and Apache OpenOffice: Free Office Alternatives

LibreOffice Apache OpenOffice

LibreOffice and Apache OpenOffice provide the core features of Microsoft Office and both are free to download, use, and distribute. More on the differences and history here.

System Requirements for Mac OS X

LibreOffice runs on Windows, MacOSX, and Linux. Java is required for certain features of the software. The Mac OS X requirements have been included below.

  • macOS 10.9 (Mavericks) or higher.
  • Intel processor.
  • 512 MB RAM.
  • Up to 800 MB available hard disk space.
  • 1024x768 graphic device with 256 colors (higher resolution recommended).

Apache OpenOffice runs on many operating systems including Windows, Linux and Mac OS X. Java is required for certain features of the software. The Mac OS X requirements have been included below.

  • OS X 10.7 (Lion) or higher.
  • Intel Processor.
  • Free memory of 512 MB RAM.
  • 400 MB available disk space.
  • 1024 x 768 or higher resolution with 16.7 Million colours.

About the Java Requirements

Both LibreOffice and OpenOffice will run without Java for most users but certain features depend upon Java, particularly the database program.

For certain features of the software — but not most — Java is required. Java is notably required for Base — LibreOffice System Requirements
Java is required for complete OpenOffice functionality. Java is mainly required for the HSQLDB database engine (used by our database product Base) and to make use of accessibility and assistive technologies. Furthermore some wizards rely on Java technology. — Java and Apache OpenOffice

Java is known to make Windows insecure. Mac and Linux users now share that vulnerability by running Flash and Java.

Remove Java if you don't need it. If installed, be sure to frequently update it and to remove older versions.

Download Java. | Test your current Java installation. | Learn more about Java.

See Oracle's Java Downloads for All Operating Systems page for information specific to Mac OS X.

PDF Editors

  • Able2Extract Professional is a powerful professional PDF program that allows you to do almost anything with PDFs. Strongly recommended. See my review of Able2Extract Pro 12 for details and full system requirements.
    • A full license costs US$149.95.
    • A 30-day subscription costs US$34.95.

HTML and Text Editors

HTML Editors

  • BBEdit ($49.99 USD) is an excellent HTML text editor.

Text Editors

Notes, the Mac OS X built-in editor, was improved greatly in El Capitan, but you might find one of these products better for your needs.

  • TextWrangler is now free, and considered the replacement for BBEdit Lite. There is a TextWrangler FAQ that should answer questions about the intended market for this product and the advantages of moving to the full-featured BBEdit.
  • BBEdit Lite is discontinued. There is still a download available here, which you'll need if you are not running OS 10.



Your Mac has utilities built in that do much of what is done by these third-party utilities, but sometimes they simplify the process.

Disk Cleanup

When deleting files, be careful to avoid system files and files related to programs as they may not run properly (or at all) if you do). Duplicate files on the system may be named the same but used for different purposes.

  • CCleaner for Mac protects your privacy and makes your Mac faster and more secure.
  • CleanMyDrive 2 is great for copying files to thumb drives including removing hidden junk files from external drives.
  • AVG Cleaner tracks down forgotten duplicate files.
  • AppCleaner can help uninstall apps that distribute many files throughout your System.

Security Notices

See Apple Product Security for an overview of Apple's security and Apple Security Updates for a listing of fixes.

Reports are increasingly appearing about malware and viruses infecting Apple computers (as well as the ever-more-ubiquitous hand-held devices).

User Groups

Macintosh user groups provide a place to interact with other Mac users, to ask questions and socialize. There are often special interest groups (SIGs) that meet regularly to discuss specific topics.
