macOS 10.15.4 Update

[beehaze]

Update went smooth as aspected. However, LG 27UL500 4K monitor has certain functionality disabled. Maybe HDR update issues. Anyone got 4K monitor working as before.

I've got a 4K LG monitor on a Radeon RX480, although no HDR. The update didn't break anything for me — works the same as it did on 10.15.3, including scaling and a little DDC-CI brightness utility. Make sure Whatevergreen is up-to-date. Then unplug the monitor cables, reset to factory settings, and choose a new profile or try doing a new calibration from the Displays prefpane.

I can confirm latest Clover is works, and now LG monitor 4K HDR is active.

Download coupled with with two reboots for install, totalled just under 30 minutes.

Once I updated Clover to r5107, the update ran perfectly.

Thanks buddy, I am with RX580 and saw HDR during the boot on top right corner. I think HDR is active and color and contrast is darker than before. Installing fresh copy to see how it goes.

In fact, it went very well

I don't know why my previous message was marked as a request for help.

I will rephrase it:

The update procedure went well. But after the update i lost the functionality to put my display to sleep.

I am not asking for help (I will do so in the appropriate place). I am just stating an issue that come up as a result to the update to 10.15.4 and may prevent other users from updating. For me it seems that it is something crucial, especially if you don't have a discrete GPU, and so you don't have sleep functionality at all!

LG Monitor HDR IS ON!

Updated Clover to 5107 as per post 1, updated kexts via Kext Updater, updated fine with 2 reboots.

At the second boot using the combo update I got the message: MacOS could not be installed . . .The bless tool was unable to set the current boot disk -69793. However when I boot back into Catalina About this Mac says it is now Version 10.5.4 (19E266) like those that post their successful updates.
So am I updated?

I see Apple Arcade in the App Store so I guess I am.

I got the same thing do you still have the install drive when you Boot?
