I don't think we will ever find out what this actually fixes since that would require Apple to admit the crackling and Bridge OS problems existed in the first place.

I had a lot of issues with high temperatures, fan noise and slow downs on my MBP 2018 before I sent it back. A YouTube video (1080p) or a big download was enough to make the computer go loud. Had some weird sounds from the speakers as well, so I guess there is a need for immediate action.

I was confused when I saw this pop up on my 2018 MBP. I thought it was a dupe of the last one. Anyway, additional fixes are always welcome.

“macOS High Sierra is reaching the end of its life as Apple prepares to release macOS Mojave”.

Your statement isn’t correct, as High Sierra will continue after Mojave is released.

And you honestly believe that a "new" macOS version will fix all the things that the point releases for the current OS version have not fixed...?

The major problem with macOS and also Windows these days is that both platforms are in perpetual beta - and QA and bug fixing are no longer on the agenda.

Don't be a Negative Nancy. One can always hope. :)

(TBH, I don't have much hope that Mojave will fix many of the stability issues we still face with HS..)

Time to download high sierra then. Always a good idea to wait for a years' worth of bug testing.

I'm a somewhat gambling man, so I installed the update. No firmware update, so whatever they did is pure software.
How is this not a firmware update?
Pre Patch:

Model Name: Apple T2 chip

Firmware Version: 15P6703

Boot UUID: 619DCF82-0FBF-4B45-999D-38DB7E24FE44

Post Patch:

Model Name: Apple T2 chip

Firmware Version: 15P6805

Boot UUID: 8D0C551C-57D0-4A14-B571-21F498366CDC

So perhaps for the firmware updates, I am used to how my old laptop would do it. 2011 17" MB Pro would have a white screen and a gray bar go across it and make a loud sound before it started updating. I guess it changed for the 2018 MacBook Pro models.

Software development has been that way for the last 30+ years.

Does anyone know if this patch resolves the issue of Target Display Mode not working with older iMacs? My late 2012 27” iMac worked perfectly as target display for a 2017 MB Pro but it does not with the new 2018 MB Pro (intermittently flickering or black screen).

It'll be interesting to see if this fixes the stability issues I've been having.

I've been seeing a lot panics while sleeping as well as other instability, but I had chalked it up to doing a full Migration rather than just user data, and was waiting until 10.14 to reinstall everything and start fresh.

So I was just installing this update on my 2018 MacBook Pro 13 and now it does not boot. I am greeted by the screen that you can see on the attached screenshot. Seing this first time since I started to use Macs full time in 2013.

Ohh well...


edit: After multiple restarts and plugging out power (the only cable connected during update) macOS was able to boot. Interestingly - High Sierra 10.13.5 Supplemental Update 2 still was shown in App Store as available (only Pro Video Formats and FCP X Supplemental Content were installed).

On the second try the update finished up fine. Glad I do not have to set up all the apps again (finished only today and have not done full backup just yet).

*Apple software engineers, if you are reading this, please fix "Right Size All Columns Individually" in Finder in column view at least for Mojave release. Make this option persistent (it only works for a single column and than you have to choose this option again or double click on the column border which is ridiculous). I have been submitting bug reports about this since ages now, including all public betas of Mojave. Common, the time is now.

I just got the new MPB a few weeks ago and immediately installed the first supplemental update. It usually gets pretty hot while doing things that i would't expect it to get hot while doing them. Like downloading a large file or playing a video on plex. And it feels like the fans are at full speed pretty often.
Not sure if this is expected behavior or not.

Try to boot in safe mode or in Disk Utility so you can try to reinstall MacOS again. If not try to use internet recovery mode to download the latest or out of box that was running on your 2018 MacBook Pro.
