How Apple scans your Mac for viruses and malware
Before we excuse what you require to do , we ’ll explain what happen without you hardly make to do a thing .

Apps are checked before they can be installed
Foundry
Apple makes it hard to put in an app that might not be secure on a Mac . mack users can pick out to only install apps from the Mac App Store , which is the dependable choice as it means that the app has been thoroughly check by Apple before being distributed .
Alternatively , there is an option to install apps from the App Store and identify developers . An identify developer is one whose software has been scanned by Apple to ensure it is good . As long as the app has passed Apple ’s test it will have a Notarization just the ticket , which Gatekeeper look for before tell macOS that it is dependable to open .
If you only install apps from the Mac App Store , or notarised apps from identified developers , you should be safe , but stupefy to the Mac App Store is the safest option as apps on the Mac App Store ca n’t be tampered with .
If you want to verify your Mac can only install apps from the Mac App Store these are the steps to keep up :
On Ventura or later :
On Monterey or earlier :
If you prefer to tolerate installations from outside the Mac App Store follow the same steps but opt App Store and identify developers from the options .
If you prefer to appropriate installations from identified developer then Apple will face for grounds that the app is notarized and it will also verify that the app has n’t been tampered with and no malware is present . unluckily in the past times there have been apps that slipped through this process because a certificate was present , such as the case of theShlayer malware , but Apple has ramped up security system since and changes to notarized apps are pushed out as required .
If Gatekeeper detect that the app has no notarization to try out the developer is certified by Apple , a message saying the app ca n’t be opened because of your configurations will be exhibit . If you hump that the software is from a legitimate developer you’re able to overturn this and launch the app . See : How to spread a Mac app from an unknown developer . However , you should be cognisant that even legitimate software package has been known to conceal malware .
App Management stops unauthorized apps from making modifications
App Management is a privacy set that arrived inmacOS Ventura . It is intended to prevent malicious software alteration by watching for endeavor by software to qualify other apps . If this happen , App Management close up the modification and alerts the drug user , who can allow it if applicable .
This means that apps can only be update by the developer of that app . A modification from anyone else will be block .
In System options there is an alternative in Privacy & Security for App Management . Users see contingent of any action that has been block here and can permit the applications to update or delete other applications if they feel that it is n’t malicious behavior .
XProtect blocks malware from running
Even if the developer is spot by Apple , the software will still be moderate against alist of cognize malwarein XProtect . XProtect will scan an app the first time it launch and it will scan the app every time there is an update issued for it .
Updates to XProtect are pushed out frequently and macOS automatically checks for update daily – a Mac exploiter does n’t even postulate to do anything as these updates are separate to macOS update . This means that even the new malware should be identified by XProtect , although Apple is n’t always as truehearted at getting this entropy updated as other antivirus solutions are . See our turn - up of theBest Antivirus for Mac , which featuresIntegoas our number one choice .
If malware is identify the app will be blocked and a subject matter will come out giving the choice to delete the software system .
To take full vantage of XProtect you need to be running macOS Catalina ( 10.15 ) or later , but we would advise that , becauseApple only supports the last three versionsof macOS , you will be safest if you are running macOS Monterey , Ventura or Sonoma .
You should verify your Mac is set to receive these update automatically by comply these steps :
In Ventura or later :
In Monterey or older :
Malware is removed by XProtect Remediator
When malware is identify on a Mac the exploiter sees an qui vive suggesting that the affected app has been moved to the trash . The user is also asked to alert others to the malware , which they can do mechanically . This does n’t mean it is entirely down to the user to cancel the app and absent the malware though .
The remotion used to involve a separate Malware Removal Tool ( MRT ) found in /Library / System , but it was n’t an app users could campaign . However , since macOS Monterey MRT was replaced by an XProtect Remediator that scans for and removes malware .
XProtect Remediator will scan your Mac at least once a mean solar day or more , and is updated much more frequently than MRT was – since MRT is no longer updated it is a good reason to ensure you are running macOS Catalina or later .
XProtect Remediator will attempt to remediate or take away malware .
The developer loses certificate and app loses notarization
If an app had been notorized by Apple but malware is identified that developer will lose the credentials that let them to distribute apps and the app will lose its notarization .
This modification to the notarization is then pushed to other Mac user so that Gatekeeper knows not to allow that app to be opened .
macOS checks for XProtect update daily , but Notarization updates are issued even more frequently , so if malware is detected , or an app lose its Notarization , Mac users should quickly be protected .
Is Apple’s protection enough?
If Mac users swear solely on XProtect and Apple ’s other protective covering there are restriction in comparison to other anti - malware solution , which are updated more regularly and have teams of specialists working on identifying malware .
The protection offered by XProtect is also more introductory than that of third - company anti - malware apps that can also protect you from phishing , social networking scams , and they can protect your Windows using friend . We make various testimonial in our test of thetop Mac antivirus apps .
XProtect is update more frequently than it was – which was one of the main criticisms – but other malware apps check for malware constantly . XProtect only checks for malware when an app is download for the first time , if the app is updated and if the status of the developer signature or app notarization changes .
Apple ’s protection should keep your Mac free from most malicious software , but they do not make itimpossiblefor malicious software package to be installed on your Mac . If raw malware is released today and you download and run it today you will have done so before Apple ’s database could have been updated . So it ’s always full to be wise when download software from unknown germ .
As we argue in a separate article : Macs do need antivirus package despite Apple ’s tribute in macOS .
How to run a Mac virus scan
macOS will mechanically scan your Mac for any malware definitions that features in XProtect , you ca n’t force it to do this . If you wish to enhance the protection to let in other variety of malware and scan for Windows virus so there is no danger of make it them on , then you would be wise to set up a third - company anti - malware app .
There are lots of third - party apps that can to glance over your Mac for viruses , including some free choice and many that extend a free trial stop .
Before you may scan your Mac for viruses you may need to visit the Privacy & Security in System options or Security & Privacy in System Preferences to allow entree .
