Decryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged in to AC power.
Not all languages and regions are serviced by AppleCare or iCloud, and not all AppleCare-serviced regions offer support in every language.
If you set up your Mac for a language that AppleCare doesn't support, then turn on FileVault and store your key with Apple OS X Mavericks only , your security questions and answers could be in a language that AppleCare doesn't support. Click the FileVault tab. Click , then enter an administrator name and password.
Click Turn On FileVault. Choose how you want to be able to unlock your disk and reset your password, in case you ever forget your password : If you're using OS X Yosemite or later, you can choose to use your iCloud account to unlock your disk and reset your password.
Choose answers that you're sure to remember. While hardware-wise both computers are vastly different they had some similarities. Both run High Sierra and both have Bootcamp partitions. Another interesting observation is the difference in encryption time between MBA with Yosemite and Mojave. There could be two possible explanations: either encryption in Mojave is slower than in Yosemite or the disk format matters.
It is possible, that encryption time with APFS is higher than with older disk formats. Does FileVault encrypt Bootcamp? No, FileVault only encrypts the Mac partition of the disk while Bootcamp partition is handled by Windows. However, it is possible to encrypt the Bootcamp Windows partition with BitLocker. By the way, you can still switch from Mac partial to Bootcamp while encryption or decryption process is still in progress. Mac will pick up where it left off and continue with encryption while you are logged in macOS.
The next test I think is the most important. Most people concern with the possible performance hit of encryption. So, I tested disk performance with Blackmagic Disk Speed Test, I measured reads and writes before and after encryption and presented results in the table below. So, does FileVault affect performance?
FileVault significantly degrades disk performance on all old Mac models. The impact of the FileVault on disk writes is the highest, in some cases, down to a half. However, the problem was fixed with the introduction of T2 chips where encryption and decryption are happening on the hardware level. As stated above FileVault is an encryption mechanism. Only users who were enabled at the time when FileVault was turned on can access and read the files on the disk.
FileVault is one of the tools provided by Apple to prevent data theft in cases of stolen or lost MacBooks.
The number of key combination in AES is 3. Assuming we use a computer which can calculate a million keys per second during a brute force attack then the time required to crack it will be 1. The FileVault requires Mac to be connected to power. Filevault encrypts all of the contents of your computer so that you and only you can access it should your computer be lost, stolen, or damaged. There are still ways someone can override your password or connect your Mac to another Mac and copy your files off.
There is a huge difference between password protection and encryption. A password is like a lock on your door: you can still come in through a window or hire a locksmith. The precise steps to follow may vary depending on your specific model of Mac, your OS version, whether you use iCloud, the security settings on your iCloud account, and whether you have additional users configured on your Mac.
But just read and follow the instructions. You may be asked if you want Apple to allow your iCloud account to unlock your disk or if you want to create a recovery key that you store yourself. For most people, I recommend using your iCloud account. If you have extra security needs and you prefer to keep it yourself make sure to store it in an extremely safe location.
If you have a folder where you keep birth certificates this would be a great location. The recovery key is your one and only bypass in case you forget your password. You may be asked to enter the passwords of other user accounts on the computer. If the computer is turned off or restarted, only users whose passwords are entered on this screen can turn the computer on.
You can then switch to one of the other accounts. When encryption starts your computer might freeze up for about 10 to 30 seconds, and depending on your macOS version you might be asked to restart.
How long does FileVault encryption take? Mac models with a T2 chip models since will encrypt instantly.
