High Sierra freezing after wake from sleep

I don't think the question is "How to avoid sleeping". It is how to prevent the computer from locking up after sleeping, and then you try to wake it up it locks up.. My two cents. Raphael

Nope. Not for me. Tks for posting though. R.

I am on the latest release 10.13.6 on a 2014 iMac. I still have this issue and have experienced it for several versions

except it is getting more frequent.

me as well 😟

Same issue. MBP 15" Late 2013. Started occurring after upgrade to Mojave.

What were the 'software issues'. Generally speaking. Did you uninstall software and then it was resolved? I'm facing the same issue on my MacBook 12.

If the system goes to sleep .

Open keychain access through spotlight , right click on login and click on change settings for keychain login .

A pop up appears .

If you check the box of lock after 5 minutes of inactivity and lock when sleeping and click on save .

The login keychain will be locked after 5 minutes or the time you set from drop down arrows and the system will go to sleep mode .

So , to avoid sleeping you have to uncheck both boxes .

I experienced this problem to varying degrees ever since upgrading to High Sierra. 10.13.3 was a bit more stable but then it started happening again frequently with the 10.13.4 update. Almost every time I came back to my iMac in the morning and waked it from sleep, my Dock would invariably be frozen and not responding, or the Finder would not respond and I could not do anything except with key commands. Often I would have to hard-reset the machine. No amount of re-installs of High Sierra would fix this.

I basically tried a combination of everything mentioned in this and other discussion threads .. disabling the screen saver entirely, turning off *all* sleep related settings (even disabling hibernation via the terminal and deleting the sleep image!), and making sure KeyChain lock was disabled. Since my system is using a solid state drive I just use the control-shift-delete shortcut to put the display to sleep manually.

So far, it has been over a week and I have not had another freeze up. Both the Dock and Finder remain responsive when waking from display-only sleep. I am using an iMac with an SSD, so obviously I would not recommend this approach for those using a spinning hard drive or if you have concerns about power consumption.

I hope this is just a temporary measure and that Apple will squash this bug in 10.13.5 or 10.14. High Sierra has been pretty awful for me in general and my iMac is only 4 years old. 😐

Some people have mentioned Safari freeze ups, which is an entirely separate issue. I found that enabling the debug menu and disabling 'canvas accelerated drawing' and 'full page accelerated drawing' put an end to all Safari freeze ups.

OK folks. Here we go.

The issue happens for me whenever I:

• Log off of ANY profile (admin, guest, or otherwise).
• Start the screensaver and leave the computer for a relatively extended period of time (10+ minutes).
• Lock the computer.
• Put the computer to sleep.

Issue: When I come back and touch/click on anything, the backlight on the screen lights up. I can actually see it lit up, albeit it is a black screen. The keyboard also lights up. But that is it. Nothing on the screen, remember, it's black. And nothing works. The computer is completely locked up.

The only thing that works is: press and hold the power button, wait for it, then restart the Mac.

One thing I would like to point out: several posts mention either a fusion drive or a fully SSD system... I'm betting that it is a problem somewhere with SSDs specifically. I may be wrong. But it sounds incredibly possible.

I will try:

sudo pmset standby 0

sudo pmset autopoweroff 0

...and report my results.

Yes, Apple should <insert expletive here> fix this.

Let you know what I find out.

P.S. I'm a Database Admin. So, not exactly a rookie. Not conceited or arrogant. Just clarifying that "most" of the time I know what I am doing.... ;-)

I'm having the exact issue - if I leave the computer for an extended amount of time, I come back to it and it seems to be "sleeping". I tap the space bar, keypad, whatever - and the keyboard lights up, but the screen remains black. I can click the power button, etc, and nothing else happens. I have to press and hold the power to hard reboot it. Then I get the pop up that the computer was not shut down properly and do I want to open the webpages.... UGH. I am new to mac and have no idea how to solve this issue.

Interesting. I have MacID installed (version 1.3.5; before it changes name for Unlox), but haven't used it since years, neither it is auto-launching at start up, though.

the same exact thing keeps happening to mine to and its brand new 😠.
