FileVault, El Capitan, 4K Monitor and Late 2013...

Hi -

I'm wondering if anyone has been running OS X 10.11.2  or later with FileVault enabled AND a 4K monitor on a late 2013 Mac Pro?

I lost the ability to display video with the release of 10.11.2 (though, my Mac Pro worked great with the exact same setup for over a year)

1. I power on
2. Chime
3. Monitor goes to sleep (I have two monitors Dell and Samsung, and both work great with my Macbook Pro)
4. After a few min, the Mac Pro powers off.

With out Filevault, the Mac Pro works fine. If I turn on Filevault, reboot, I'm back to no video. I can get video on an old 1600 x 1200 monitor.

This issue is not the same where the 4K monitors would not wake from sleep, which was resolved in 10.11.3.

The computer has been a brick for weeks at this point and Apple support is not able to help me.  I've been going back and forth with them for weeks. I've had most of the hardware replaced in the computer, the GPUs, though, not the CPU. I have a 6 core CPU.

I'm wondering if anyone has been able to use FileVault, OS 10.11.2 or later with FileVault enabled? What CPU do you have?

I really don't know what else to do (other than turn FileVault off, and that's not a solution) at this point. I've got a $7000 Mac Pro, with Apple Care, that has not worked in weeks and am loosing my mind at this point.

Thanks

Try updating to 10.11.3

Yeah, 10.11.3 and 10.11.4 beta 2 make no difference and don't solve the issue.

There are relatively few things that would make your Mac Pro power off. But one of them is not being able to mount the Boot Drive.

With the screen off, You may not be seeing the evidence of this happening.

Powering off is not the problem here. The computer works fine with a non 4K monitor

Have you disconnected everything except the 4K monitor?

Yes, done all this with apple support. Two different monitors, different cables, etc...

ist this problem solved? I have exact the same problem too

It won't startup with a 4k monitor attached via thunderbolt if filevault is enabled.

This is a problem I've had open with engineering for some time. This has been an issue for multiple releases of the O/S and is an issue across multiple resolutions and monitor manufacturers.

If you connect a non-4k monitor to the thunderbolt port then it works fine. I've also had it work properly with an Asus PQ321Q (UHD).

It fails for me with both the Dell P2715Q (UHD monitor) and the LG 31MU97 (4k monitor).

If you boot with a non-4k monitor and then connect the 4k monitor you can then disconnect the non-4k monitor; but the non-4k monitor has to be connected for each time you reboot or startup.

If you boot up with a non-4k monitor and turn off filevault you can swap a 4k monitor for the non-4k monitor during reboot and it will start up fine.

This is extremely frustrating.

My Mac Pro is JUST out of warranty. Same issue (My post is here.)

But for me, I have no video out to ANY device, including my simple 1280x800 HDMI projector, even after forcing multiple reboots with my 4K (Dell) display not connected at all.

So I think it's a Mac Pro/GPU issue in general, affecting some displays and not others (?), but NOT an issue specific to 4k displays.

Two other symptoms of this situation: caps-lock key won't light (Apple BT), and volume keys don't click. AFTER logging in, video works, and caps-lock and volume behave normally.

In case it hels you: the only way I'm surviving is that I discovered by trial and error that the machine isn't quite a total brick. You CAN log in. Then the video appears.

Here's my ritual:

1. Cold boot the machine. If it's already on, force-shutdown (hold power button until machine goes dead).

2. Wait... an arbitrary amount of time for booting. Haven't figured out the optimal timing. Too soon and you can't log in. Too late and the machine sleeps, but you can wake it with the power button (in fact, this re-weaking may make the display come on—but it takes so long to happen that I don't use this method).

3. Hit Esc a few times to clear anything that may pop up. What? I cannot say. Bluetooth wizards? I just know that sometimes logging in doesn't work, so I do this preventively.

4. Move the mouse (blindly) to top-left and click, to make the login screen "active." (Sometimes it isn't—I've long noticed that even when I used to have video.)

5. Type enough of your login name (even one character) to be unique, and press Return.

6. Carefully type your password and press Return. (Be careful not to touch Caps Lock. I think the key does work, it just doesn't light up, so you don't know it.)

7. Hold your breath and wait.

8. If nothing shows up after a while, try unplugging/replugging power to the display.

9. If that fails, repeat from step 3. (I really hope there's no limit to Mac login attempts.)

10. If THAT fails (and sometimes it does!) force-shutdown again and repeat from step 1.

This is all VERY stressful, including the ugly force-shutdowns, but so far, I have been able to get my Mac running after a power-down. Knock on wood.

Other blind experiments I want to try to make video appear: VNC screen sharing (maybe to iTeleport on my iPad), Safe Boot with Shift, booting with Option key (to choose startup disk), booting to recovery mode, and logging in as Guest so there's no password to get wrong. (But with File Vault, I know Guest mode takes extra steps/reboots.)

This is a horrible problem, and I do not mean to make light of it.

But why not turn OFF FileVault for your desktop Mac Pro for the time being until this problem gets cleared up. Enable findMyMac for use in the unlikely case that its gets stolen -- then you can track it and remote-lock it if needed. And disable auto-Login to slow down anyone who grabs it.

These are not nearly as stealable as a MacBook, and if you are working where it will be subject to theft, get a lock and/or bolt it to the table.

Still not fixed. Unbelievable.

I haven't updated to Sierra because I'd lose compatibility with my version of LightWave. I'm saddened to hear it's still the same.

Regardless, I'm still stuck with it in El Capitan—and I found out that there IS a limit to how many blind login attempts you can make. My entire machine was bricked and I had to use iCloud recovery to unlock it. Thankfully that worked, but  super stressful.

My main workaround is to never power down anymore (sleep/wake has the same problem, but less often). Not much of an answer when I need to travel.

(As for turning off FileVault: the owner of this building and dozens of employees have access to the master key. My clients' info is on the machine, not just my own. Turning off encryption and "taking my chances" would be irresponsible—not to mention a stressful and lengthy process to wait through.)

I have a variant of this problem.

Asus PQ321 running 4K@60Hz via MST DisplayPort on MacPro with D700s.

Filevault enabled.

Any reboot - blank screen.

IF I connect via HDMI only gets 4K@30Hz but does boot up.

Once I boot I can swap back to DisplayPort and up comes 4K@60Hz.

The ritual now is anytime I need to reboot, I connect via HDMI until booted.

Painful yes, but it works.
