If you want to use something then probably the best free option is Avast, or if you want to spend money then have a look at Sophos. I have been using Macs for about 35 years and have not used antivirus programs at all, but I am careful about what I download and from what sources. You can, of course, use both Time machine and CCC to different disks for redundancy.Īpplications can be re-downloaded from App Store or reloaded from original images if purchased outside the App Store. CCC is expected to soon have the capability to produce a full bootable backup of your Big Sur system ( it already has this capability for non-M1 Big Sur systems). Time machine is included with macOS, whereas CCC is a paid program but one of the best investments you can buy for USD39.99 for a licence which covers multiple machines. Both of these will back up all your data. MacOS Big Sur has a number of built-in features to improve security, including a non-writable system partition on the disk which has checksum protection, and in-built security checking in Safari.Įven if your disk is totally wiped, you can download a new system installation image via a wireless internet connection and restore your system.ĭata backups should be performed either using Time Machine to an external disk, or using Carbon Copy Cloner (CCC) to an external disk.
