The Best Antivirus for an Old Mac


When it comes to the best antivirus software for an old Mac, users have a couple of different options. If a user is unable, or simply doesn’t want to update macOS on their device, they can still receive antivirus and malware protection in thanks to the software below. Most of these have free options that will perform simple virus scanning, however, virtually all of them also offer subscription models than can provide users with even more protection and features.

When it comes to antivirus software, there’s a pretty large debate as to whether or not devices that stay up-to-date actually need it or not. Regardless, if you are running an older version of macOS, it is highly recommended that you use antivirus or malware software.

Does My Older Mac Need Antivirus Software?

While a user may have their reasons for not wanting to update to the latest version of macOS, having a device that is not up-to-date can create some security issues. In addition to not receiving the new features that arrive in a macOS update, users are also missing out on security patches and fixes for typical exploits.

Essentially, if you are running an outdated version of macOS, your system is likely less secure, especially depending on how old the software you are using actually is. Keeping antivirus software on your device is likely a good idea if you are running an older version of macOS.

Choosing the Best Antivirus Software for an Old Mac

With that in mind, I’m going to recommend some antivirus software that work nicely with older Macs. I will also inform readers what software is capable of protecting older operating systems. Just because you are running an older version of macOS does’t mean that you can’t do your best to protect your computer. Continue reading to check out my suggestions for antivirus software that can protect your device.

CleanMyMac X

Next up, I would also recommend CleanMyMac X by MacPaw. Available for devices running 10.12 or newer, it can be a great alternative for those that have not updated their macOS in a while. MacPaw does note that there is a version of CleanMyMac X for 10.10 (Yosemite) and 10.11 (Capitan), these versions do not receive new features. However, while these versions do not receive new features, they do still receive updates to their virus and malware databases.

What makes CleanMyMac X so appealing is that not only does it offer malware protection, but it can also clean a user’s machine of any older or unnecessary content, giving users access to hard drive space they may not have seen in a while.

Finding What Works Best for You

When it comes to protecting your machine, there’s option for those that are running older versions of macOS. While it is typically a good idea to keep your device as up-to-date as possible, that may not always be an option for some users. Running an older version of macOS only makes antivirus software more necessary, as users are missing out on security updates from Apple.

With the vast majority of these selections offering free trials, you likely won’t have to pay if you are looking for a simple virus scanner. However, each piece of software does provide further benefits and features if you upgrade to a premium subscription, I would recommend checking the features entirely to pick the antivirus software that works best for you. Just because your macOS may be out of date doesn’t mean your device should susceptible to viruses.
