Its surprises me that Apple basically enabled this by default but didn't give users any of the backup options in case you "forget" your password.

With the new encryption in iOS 8, it seems that Apple really does value our privacy and that they want us to protect ourselves from theft and *cough the fed cough cough* in any way possible. Way to go Apple!

Thanks for your replies.
I never had FileVault enabled before. It's a unibody MacBook, but connected to a screen, Ethernet, and Bluetooth keyboard and mouse.

Could these peripherals make it believe it's a desktop?

I was prompted on both my iMac (2010) and MacBook Pro Retina (2013). Are you positive you didn't accidentally rush by the prompt window?

In any event, you can simply go into System Preferences ---> Security & Privacy ---> FileVault to check its status and enable if needed.

I didn't rush through, as I was looking for the option specifically. I've also tried a couple of times. I know that it can be enabled later on but I don't get why my installer is different from everyone else's.

I may try redownloading the installer to see.

Has anyone else used a USB installer?
At what stage of the install does it prompt you? Between which windows?

Thanks

Definitely a good thing !
But without recovery key and no explanation so far about how it works... Hope we will know more soon

I enabled it and then disabled it after realizing I couldn't remove the partition with Yosemite beta. I had Mavericks with the beta on a separate partition.

So enable, fight trying to figure out why I couldn't delete a partition, disable, delete partition. Now given my Wifi issues I haven't enabled it again as I'm thinking to revert back to Mavericks on my MBP.

I do not have Fire Vault enabled...

I do not have Fire Vault enabled... on Yosemite obviously..

Thought i'd check what options come up if I attempt to ENABLE firevault on a Yosemite installed system.

Clicked on TURN ON FIREVAULT - in System Preferences> Security and Privacy.. of course.

This is what I get: A POPUP BOX....

Your iCloud account [email address] can be used to unlock your disk and reset your password if you forget it.

Two option boxes:

1) Allow my iCloud account to unlock my disk
2) Create a recovery key and do not use my iCloud account

I only have the option to select either or, not both.

I have decided not to enable it, just wanted to share this with you guys.

Hope it helps.

I "accidentally" enabled FileVault after Yosemite was installed and being prompted to enable it.

It is STILL encrypting my files since I installed Yosemite on Friday - ~500GB data on a traditional HDD.

I want to disable FileVault immediately after it's been encrypted and want to know if decrypting/disabling FileVault will take long?

Thanks

The decrypting will take just as long. It takes longer to encrypt / decrypt when you are using the computer as it is working. I have the same size HDD and it takes 5 - 7 to encrypt, depending on how much data is on the drive and if it is being used at the time for other tasks.

The only way around that is if you delete the drive in disk utility via a Command +r boot and reinstall the OS.

Damn, I'm guessing I should expect about a couple of days for decryption.

Thanks for your help, much appreciated.

For those who have FileVault enabled and also backup to an external drive, you might want to consider encrypting the backup drive as well.

Encrypting the external backup drive will allow you to create a single password to unlock it. If you forget the password, there will be no retrieving the data on the backup.

So I tried again. Same result. For some reason, Apple don't offer an option to encrypt my Mac during Yosemite setup. I can't figure out why!

Anyway, I'm doing it manually. There's no difference is there between the FileVault option in System Preferences and the one offered by Yosemite during install?

Installed OS X Yosemite (10.19) on a mid-2013 MacBook Air that had been running Mavericks. Enabled FileVault at installation but didn't realize that it would need a lot of time to encrypt files. I detached the Air from the power cord which apparently paused the encryption process and now I can't get it to resume encryption. I've turned it off & on several times but it still shows as "paused" in Systems Preferences although the blue progress line looks like it's moving -- all else seems to be working just fine.

What can be done? A complete reinstall or is there a way to start up the encryption process again so that it finishes?

Thanks in advance for any suggestions!

Doing it manually provides you a few more options (provides the actual key, can store the key with Apple if you want for subsequent retrieval). The core process of encrypting the drive between the default install method and the manual method are the same.

If the blue progress bar is moving, I would let it finish the process, reboot, and then check the system preferences again to make sure it is encrypted. You can also check afterward in terminal via the diskutil list command.

Is the fact that it is encrypted and that my Time Machine is not the reason why I cannot browse my backups?

Nope. Having FV2 on does not impact the way Time Machine works.

I posted an idea in your other thread.

Thanks for the quick response!

I'm not sure if FileVault is actually doing anything though. On the one hand, the blue progress bar isn't showing progress -- the blue is just sort of undulating. Also, it just says "Encryption paused. Connect power cord to resume encryption." The power cord is and has been connected but there still doesn't seem to be anything happening. On the other hand, if I try to select "Turn Off FileVault," I get the following: "File Vault is encrypting the data on your disk. Wait until your disk is fully encrypted before turning off File Vault."

Fortunately, I learned from this and did NOT enable FileVault when installing Yosemite on my iMac. Clearly, it's not quite ready for prime time yet!

Thanks again!

I have a new Macbook pro retina and did the same mistake of encrypting the drive. Never used the machine before and i can not get it to resume from a paused status after 2 days plugged into the power. I chatted with apple support that states that it is *cosmetic issue* as it should be finished in 8 hours but unfortunately that is not the case.
A message warning the user of the length of the process before any action is allowed (in order to start encryption) should be issued.
Please be aware of this issue before getting into this nightmare.

Did the same on one of the Air`s in the house, however it just resumed without issue. We still have two 15" MBP`s with spinners and have left FileVault unchecked on those two.

Retina`s took easily less than an hour with around 200Gb on the SSD`s one a 256 other a 512, the latter being appreciably faster. Depending on your usage encrypting the drive makes good sense and with SSD enabled Mac`s pretty much zero slowdown, all mine are encrypted. Personally it`s a good move and if you value your data/privacy the way to go.

Hello,

Two quick questions:

-Is Filevault 2 as secure as Encrypted disk images?
-Has filevault 2 performance/security improved since 10.8.5?

Thanks

Loa

1) yes
2) performance is fine. I haven't noticed any slowdown. Security is 128 AES. I feel comfortable with using it.

Edited to add: More than likely, you won't get a encryption key once it is enabled after initial install. Yosemite is supposed to post it on the screen. However, in all the times I have tested, it has only done it once.

If you forget your password or are unable to input it into your Mac, you could be in trouble.

If you do the default install options with Yosemite, the encryption key will be your Apple password, provided you don't change anything.

Thanks for the insight BasicGreatGuy.

I'll wait until I have a couple of hours and enable it.

Is it easy to do for external drives?

If you want to encrypt a Time Machine backup, that is as easy to do as ticking the "encrypt time machine backup" box in Time Machine setup.

If the external is for other uses, you can encrypt the drive in Disk Utility.
