Yes, I bought mine to use as a Time Machine backup for my iMac. As with most external drives you might buy, however, it comes formatted for use on a PC. It does include backup software that can be installed on a Mac, but I would recommend against that unless you aren't interested in using the iMac's built-in backup software. If you intend to use this as a Time Machine backup, it should be reformatted using Apple's Disk Utility, which can be found in the Utilities folder inside the Applications folder, or simply click on the Spotlight eyeglass on the right side of the menu bar and type Disk Utility. After plugging the drive into your iMac, it should appear in the list of disks on the left side of the Disk Utility window. Click on the drive and then click on the "Erase" tab, select the format you wish to use and type in the name you wish to give your new disk drive, then click on the Erase button. Time Machine backups need to be formatted as Mac OS Extended (Journaled), and if you wish, Encrypted. Encryption provides another layer of security if there's a chance someone might break in and steal your Mac - otherwise it's not necessary. Once it's reformatted, your iMac will probably ask you if you wish to use the disk with Time Machine, so just click Yes. If you plan to use this for mass storage for something like storing your photos or other media, you can use Mac OS Extended (Journaled), or you might want to use Apple's newer APFS format, which provides better file management and faster searching, but it's only compatible with newer iMacs running Mojave or Catalina.
