Can't enable File Vault 2 in Lion on Mac Pro

Going insane trying to get file vault 2 enabled on my mac pro.
It's an older octocore mac pro (2x2.8 GHz Xenon) with 10 GB RAM. I have a 2 tb startup disk, another 2tb disk, and a pair of 1.5TB disks that form a mirrored RAID.
i tried enabling file vault on one of the startup disks and it would enable then restart, and i would get to the login screen after the restart and the keyboard would be frozen (usb) and so would the mouse. i started going nuts and tried to boot into recovery mode but i would hold down my keys and would be greeted with (after the initial grey startup screen) a white screen for a second, and then it would just boot up normally.
ok...
repaired permissions and verified disk, said it needed repair. coudln't figure out how to get it fixed because the stupid computer won't boot in recovery mode. made a recovery usb disk and it still wouldn't boot in recovery mode even with the stick.
started it as a targeted disk and ran disk util from my laptop. coudln't repair it, siad the disk was corrupted and needed to be formatted.
SO.
formatted the OTHER startup disk, extended/journaled, and installed lion on it cleanly using my usb installer. figured i'd turn on file vault on the brand new untouched install and then run migration assistant.
guess what: when i restarted it, i still got the login screen without the ability to use the mouse or keyboard.
pushed the power button, turned it back on, and it ignored all my attempts to get into recovery mode and continued to boot up normally.
what's going on?!!? pulling my hair out...!! any thoguhts are much appreciated!

It seems your hard disk is damaged from time to time this give tremandous problems even before booted as the Mac wants to read stuff he can't...

Can't enable File Vault

Decided to try out Leopard on an external USB drive before overwriting Tiger.
Clean installation on an external USB drive(Intel Macbook) boots fine.
File Vault tells me I cannot enable as the Home Folder is not Mac OS Extended Journalled when it is - it's actually Journalled case-sensitive - should that matter?
Also tried installing a demo of Adobe Dreamweaver and that gives me an error of incompatible volume format.
Is this a known bug with external USB boots?
Another thing I can;t do is partition it to try out BootCamp.
Any ideas?

I think the problem with a case-sensitive file system is that not all software vendors make Unix compatible products. If you have two files with the same name save the case, abc.txt and Abc.txt, some programs may crash because they "see" two "identical" files.
Until all the world agrees on case-sensitive names, then I would not recommend using such a file system. And as long as we have Winders, that won't happen.
In fact, I suspect some of the problems may well be from MS Office products running on BSD, but that's only a surmise. Then there is the networking problem when "talking" to a file system that is not case-sensitive.
I have read enough pro and con to consider that the world is not yet ready for case-sensitive file systems, especially on computers with dual-boot capability and that can run BSD and GUI apps at the same time.
Yes, FV and TM do not really conflict. It's the way FV encrypts your folders. It makes each folder look like a single large file, so TM cannot do anything with it but save it as a unit. If TM could look into the folder that would mean the encryption is useless, right?
Of course, you can exclude that folder from TM and back it up separately on your own.
The alternative would be for FV to encrypt each and every file separately, but that would probably slow down the processing more than doing in in one big chunk.
Also when using FV, TM only backs up after you log out, for obvious reasons (in retrospect), so nothing happens until you do log out, and then you can't turn the box off until TM does its thing.

Login screen on MacBook Pro Retina (Late 2013) with enabled File Vault is extremely slow (suttering)

Hi
I have a MacBook Pro Retina (Late 2013) with enabled File Vault on OS X Mavericks. When I boot up the mac freshly it takes quite long to get to the initial login screen (which as I understand is a pre-boot login provided by the recovery partition if File Vault is enabled). However, what is even more bothering me is that once I get to this screen, the whole UI is behaving extremely slow. The mouse makes jumps of a few inches on the screen and the animations (e.g. if you click a user and then an animation shows the password entry field) are running in slow motion and only update every few seconds. Typing the password afterwards runs smothly again (altought for example moving the mouse at this point still behaves as described before). After loggin in to the account OS X runs fine without any hicks. Can anyone give me a hit what this could be and how I could resolve this?
This has already been done:
Reset PRAM
Boot into recovery partition and run repaired disk and disk permissions
Run all OS X maintenance operations and cleared caches using OnyX
What I could imagine is that somehow the recovery partition is damaged (which as I understand is used to boot to the login screen if File Vault is enabled).
Any help would be greatly appreciated.

Just ordered a Retina MacBook Pro11,2 (mid-2014 15", 2.2GHz Intel Core i7, 16GB RAM, 512GB SSD, OSX 10.9.4 Pre-installed - Build 13E28) and have the exact same issue. The first thing I did when i booted it for the first time was enable FileValut2 and encrypt the disk. Though I failed to notice this behavior prior to encrypting the disk, the stuttering/lag happens without fail every time I have logged in from a cold boot, locked screen or sleep. Additionally I have noticed the same stuttering behavior when switching tabs on various built-in OSX applications such as the tabs on the About This Mac > More Info.... (System Information) dialog for example, and similarly other dialogs that experience this behavior of resizing when switching tabs. I was running no other software than About This Mac > More Info ... (System Information) and OSX 10.9.4 itself. The issue happens without fail with and without a USB mouse plugged in.
I am really glad to have found this thread and with such recent posts. I'd love to find out that this is just a software bug that will be fixed when OSX 10.10 "Yosemite" is released. If not, I hope the cause of this bug is determined soon so I can still exchange or have it repaired.
Migflono and Matthew, would you be able to post your hardware specs for comparison?

Problem: securely erasing home folder after enabling file vault

I enabled file vault. It took 4 days (125 GB) to "securely erase home folder", then when it finally reached 100% I got an error message that it could not be erased after all. I also now got an icon on the desktop (protected house) showing my home folder. Anybody experience with this? What do I do to securely erase? What can I do to speed it up? I have 4GB RAM and a HD of 500GB

open /Applications/Utilities/Terminal.app
At the prompt type:
diskutil secureErase freespace 0 /
(press return)
This will secure erase free space on your boot volume.
Level "0" (zero) is a Single-pass zero-fill erase. Levels 0 through 4 are supported.
Here is a full description of the different erase levels: 0 - Single-pass zero-fill erase.
A. 1 - Single-pass random-fill erase.
B. 2 - US DoD 7-pass secure erase.
C. 3 - Gutmann algorithm 35-pass secure erase.
D. 4 - US DoE algorithm 3-pass secure erase.
for more info (in Terminal) type:
man diskutil
(press return)
This should take considerably less time than 4 days. On my Mac Pro with 162GB boot volume,
130GB free (I keep my data on a different volume) it takes about 10 minutes using level "0".
Disk Free Space Warnings are normal during operation and can be ignored.
more info about it from apple support:
http://support.apple.com/kb/TA24002
You can invoke the erase procedure from Disk Utility GUI interface, but it usually is quicker
when run from terminal.

Enabling File Vault

Wow it looks like I avoided a lot of trouble with the File Vault Death problem by just doing an erase and install. However, I'm trying to enable File Vault on my newly created user account and I keep getting an error message saying that I cannot enable it because the "home folder" is not an Mac OS Extended format volume.
Now I know that's false since I made sure that the hard drive was reformatted to an Extended format volume when I installed. Anyone else having this problem? If so, has anyone figured out a solution? My only one would be to reinstall Leopard again, but I really do not want to have to do that if I can avoid it.

Could it be possible, that the GUID filesystem is responsible for this misbehaviour? I think, before I've changed the HDD in my MacBook Pro the original Apple HDD had an Apple filesystem and it was possible to enable FileVault. Now I have built in an Western Digital WDC WD2500BEVS-00UST0 and it isn't possible.
HTH and kind regards, Friedrich

Can't disable File Vault

I wanted to disable the File Vault for my account. The password is correct. But after a while there is an error message that it can't be disabled and it stays enabled. This is after I had installed Leopard.

Can't disable file vault on MBpro
That's your only choice.
Copy enough stuff to an external HD so there will be room. After deleting the copied from your home folder, you may need to log on and off more than once to reclaim all the space.
After you migrate, copy back from the external HD.
(If you don't have an external HD, get one -- you should have one anyway so you can make regular backups.)

Is there an issue using file vault 2 on a Mac fusion drive

is there an issue using file vault 2 on a Mac fusion drive

I'm using that configuration and it works for me. There have been some reports of kernel panics with FileVault and SSD's. The cause is unknown. Chances are you'll be fine, but make good backups.

Can I watch downloaded tv episode on my mac pro that I utilized to download this episode from itunes?

Have you downloaded the show onto your Mac ? If you have it should show in the TV Shows part of your library e.g. with the left-hand sidebar enabled (option-command-S ona Mac) and TV Shows ticked on the General tab in iTunes > Preferences (command-comma) so that the category shows in your library

Don't know! You'll have to give us more details of what's happening when you try. Can you print other documents OK? When you try to print, does the printer icon appear in the dock - click on it and see if there are any printer messages.

How can I hook up 3 screens to a Mac Pro 8 core 2010 model?

How can I hook up 3 screens to a Mac Pro 8 core. One is a 23' Apple Cinema Display, the second is a 20" Apple cinema display and the 3rd is a 32' Sony Bravia HDTV (connected to mini port with mini/HDMI connector) Do I need to buy another video card? I have heard about 4 different scenarios about this, and they all sound a bit complicated. I thought that you could automatically connect 3 displays with the card that comes with the MacPro. It has a DVI port and 2 mini ports, so it appears that would be for 3 displays. But this is where it gets strange. Any thoughts?

Which video card? 5x70? If you read about the various scenarios thern for 5x70's you need two active adapters for thee monitors (TV considered a monitor). And you should have seen references to these apple docs:
Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
It's not really complicated. Search out the appropriate adapters and hook 'em up. For the 23" and 20", if they are DVI, you need single link adapters. For the TV, if you end up using the DVI port for it (because possibly you can't find the appropate adapter cmbination) then you need to handle the audio separately since DVI doesn't carry audio.

Can i hook up my xbox 360 to mac pro 27

i wnat to know how or if i can hook up my xbox 360 to my mac pro 27 as a screen to play games

I suppose you can. You're talking about the desktop Mac Pro, right?
just takin' a stab at it here, but I think elgato has a game capture box which might be helpful. It does mention xbox 360 and ps3. if it's for a MacBook Pro, I can't say for sure. Maybe blackmagic??

Can I put two GT120's in a Mac Pro?

I just put a ATI 4870 in my Mac Pro and I took out the standard GT120. My father has a Mac Pro as well and I thought about putting the card to use by installing it in his Mac Pro.
Both our Mac Pros are the most recent version. Only difference is that his is 4 core and mine is 8.
So can I do this? Can I put two GT120's in his Mac Pro, and would it even make a difference for him. He mainly uses Aperture 2, and Office apps.

Two cards only allow more displays to be connected.
Rendering for all displays is still done with only the primary card.
The information is then passed along the PCIe bus to the additional cards.
What additional cards actually do is to increase bandwidth loading of the PCIe bus, which can result in a net decrease in performance.
Some applications are not multi card aware, and can result in negative performance.
One example is the case of two identical cards and FCP:
http://www.dvinfo.net/forum/non-linear-editing-mac/145449-dual-graphics-cards-ma c-pro-final-cut-pro.html
Note that the "solution", that is to use two different cards, is a result of the fact that rendering occurs on only one card.
