![]() You can look at the resource monitor and see exactly how much the drive is taxed by encryption. That’s what you’ll typically see when FileVault is working hard. So, if you have something that involves a lot of drive activity, it can slow things down. Storage drives, as a rule, are much slower computer components than the rest of the major hardware pieces. If every single file has to be encrypted, the storage drive has to do the literal work of encrypting (and decrypting) those files. Instead, when it creates a problem, it makes everything run slowly.īut, if FileVault is slowing down your computer, there are really only two things you need to look at: the storage drive and the processor. So, if FileVault is eating up computational resources, it can slow down the computer’s performance in general.įileVault doesn’t cause random errors on the machine. It takes a lot of resources to encrypt so much data (especially if you have a lot of stuff saved on your Mac). When you think about the fact that FileVault interacts with every single file on a computer, it’s easy to imagine that this might slow things down. How Does Encryption Impact Your Mac’s Performance? (2 Ways) It also involves a lot of processes in the computer, and that’s why FileVault can potentially affect performance. This is done with every single file in the system, so it is deep and robust. Without the key, you can’t make any sense of the information stored on the computer. Using the correct key, FileVault can unscramble data and make it easy to read again. If you try to read the scrambled data, it will make no sense.īut, the scrambling is done according to a specific code and algorithm controlled by FileVault. ![]() To do this, FileVault scrambles data on the drive. Put in simpler terms, it encrypts absolutely everything tied to Mac OS (or OS X on older systems). It encrypts the entire partition of a drive used for a Mac computer. This all makes more sense when you understand what FileVault does and how it is done.Įssentially, FileVault is an encryption program for Mac computers. Minimal desktop area for productive work. 4.2 #2 Alternative Encryption What Does FileVault Do? Modern workplace.
