FileVault adds that the final layer of security for your information stored on your Mac via XTS-AES-128 encryption with a 256-bit key.īelow is the step-by-step guide to encrypting your macOS hard drive with FileVault. If, for example, your laptop had sensitive information stored on it and was stolen or hacked, malicious actors would need to have your encryption key to “unscramble” the data and make sense of it. The reason encryption is such a fundamental part of security is that it scrambles the data so it is entirely unrecognizable without the encryption key. This process of encrypting and decrypting information on your Mac’s hard drive happens on the fly as you use your Mac. Its job is to encrypt the data that is already stored on the startup disk of your Mac and any new data coming in as you use your Mac. Your Mac comes with a built-in encryption feature called FileVault. Review collected by and hosted on G2.com.Your Mac comes with a built-in tool for encryption help your security team out and put FileVault to work. Another known issue with FileVault is in business environment where computers are hooked to Active Directory for account password management, there's often some poor syncing between AD password and FileVault password causing headache to users. We experienced this issue on MacOS Sierra (10.11) but not so far with MacOS High-Sierra (10.12), however since High Sierra is on the market for only 2 months and that FileVault remain unchanged in this version, we anticipate some issues later. Moreover, FileVault have a few "known issues" that several users reported and that we experience in our company too, where some computers refuse to boot because of some kind of corruption with FileVault, so we had to turn off encryption (de-encrypt all datas) to get computer booting back again and then turn it on again, then it work for a few months. In opposite to other data encryption software such as Microsoft BitLocker, FileVault seems to affect computers performance badly, even the latest generation of MacBook Pro with extremely fast SSD drives.
