Sleep Wake Failure with High Sierra 10.13.4

Since installing 10.13.4 on both of my iMacs, I have noticed a Sleep Wake Failure on my 2012 iMac.


Once it has gone to sleep, it will display the log in screen, I enter my password and it will hang. The only solution is to hard reset the system, where it will "bong" twice before presenting me with the login screen (NB: It is File Vault enabled).


This did not happen until I installed 10.13.4 prior to that it was working perfectly.


I don't seem to get this error on my 2017 iMac.

iMac (27-inch, Late 2012), macOS High Sierra (10.13.4), FileVault enabled

Are you using FileVault?


From my tests, it seems that 10.13.4 cannot wake up properly if your disk is encrypted with FileVault. 😟 The result is a black screen if you wake by keyboard or mouse (or rarely a non-responsive login screen).


If you press the power button to wake instead of using the keyboard or mouse, the iMac will turn on, turn off, then turn on again to perform a cold boot.


With FileVault turned off, it wakes perfectly every time.


Anyone on 10.13.3 reading this: if you need disk encryption, do not install the 10.13.4 update!

Same problem here.


MacBook Pro 13” Retina with 10.13.4 and FileVault enabled.


After having the MBP in sleep mode for 3 hours (standby delay 10800), when opening the screen, the login screen is shown and after entering the password the computer freezes.


Filed a bug with Apple. I hope issue gets fixed in 10.13.5.


As a workaround, I've extended autopoweroff and standby to more than 12 hours. It should keep the MBP in the sleep mode overnight.

Same issue here with a Late 2013 iMac 21.5 inch Core i7 with Fusion Drive. Scheduled sleep/wake worked perfectly until 10.13.4 installation. I do not, and have never had, FileVault enabled. A SMC Controller reset, and an NVRAM reboot solve the issue but only for 24-48 hours. The machine won;'t go into sleep mode when it's supposed to, and when the screen is "awakened" after overnight, the 5-minute sleep warning appears. Something is preventing the sleep countdown cycle from beginning at the proper time, and when the screen activates, the iMac "believes" that it's time to go to sleep.


Awaiting this to be fixed in 10.13.5 and I've reported it using the Feedback Form.

Same problem here also, mac mini 2012, started exactly after the 10.13.4 update.

I get the hang, log in screen with unresponsive keyboard and mouse, and I am using FileVault. Have already tried all of the recommended fixes including reinstalling macOS with negative result.

Since I should not have to relinquish FileVault, I'm looking for more options. Have not heard anything from Apple yet. One thing I am going to try tonight is running with the SLEEP MODE turned OFF;

{Choose Apple menu > System Preferences, then click Energy Saver}

I have read some tech notes that indicate the sleep mode has a record of interfering with log ons and boot ups as well as keyboard/mouse malfunctions.

I've also seen where there is a 'combo update' available on this thread, not ready to try that yet. Anyone else with any ideas (except turn off FileVault) are welcome. toodles.

I have this problem, too.

- iMac 21" late 2012

- Fusion Drive

- FileVault enabled


Already reinstalled OS once (had some kexts, etc., that I didn't trust), problem remained after enabling FileVault.

Haven't played with Power Management Settings.

Haven't tried 10.13.5 Beta on this system (running it on other Macs, but this is my PROD machine, so my personal policy is against using Beta on that one - was burned once already by the issue where APFS conversion killed machines with FusionDrive)


Have filed Bugreporter ID 40155960 with sysdiagnose in order to help Apple to identify and solve the problem.


Never happened on my 2017 MBP or 2015 MB, where I've been using every 10.13 Beta version available since 10.13.0, and where I am also using FileVault as well as hibernation, so it seems to trigger on Fusion Drive/Bluetooth or other iMac-related aspects.

I've neglected mentioning the Bluetooth issue because my issue with the sleep/wake appears to be related to File Vault. However, I did notice that when I had File Vault enabled on my iMac, the battery life on my Apple bluetooth keyboard was depleted in just a few days. I have the older keyboard that uses the AA batteries and even though they're rechargeable, their typical service life is several weeks. With FV disabled, battery life is back to normal.

Dare I ask if anyone knows if this issue has been fixed with the beta 5 version that's just been released? I feel we are getting close to the final release 😐

I am testing them now, on beta 4 Apple asked me to provide more logs for troubleshooting.


Currently there seems to be a change in the wake-hibernation behavior, I ran 'sudo pmset standbydelay 1 hibernatemode 25 autopoweroffdelay 1' and put it into hibernate immediately, when I woke it, it immediately went back to state it was in.


I am not sure if this issue is "fixed" considered I expect to see a FileVault password prompt (for security) - I will find out once more testings are done.
