macOS 10.14.5 random system freeze

Recently upgraded macOS 10.14.4 to 10.14.5 on my MacBook Pro (early 2015). Ever since upgrading, my Mac experiences random system freezes where the machine becomes totally unresponsive and only a hard power-off is able to fix it. There does not appear to be any noticeable pattern in terms of programs running at the time the freeze occurs. I upgraded to 10.14.5 about 1-2 weeks ago and have experienced 3 such freezes so far.

In addition to the system becoming unresponsive, I also notice that any audio playing at the time of the freeze also seems to "freeze". The machine appears to go into an infinite loop of emitting a "pop" sound every second while continuing to playback whatever sounds were active just before the machine freezes.

Up until installing 10.14.5, I have never encountered this problem before on any prior version of macOS.

Curious if anyone has experienced similar issues. Wish I could downgrade my Mac to the previous macOS version.

MacBook Pro 13", macOS 10.14

Apple support was able to provide a solution for effectively "downgrading" my OS.

1) Follow the instructions provided at https://support.apple.com/en-us/HT204904 to reinstall the version of the macOS that came with my laptop.

2) Upon completing step (1), the App Store is supposed to provide me with access to various versions of the Mojave installer. The recommendation is to start by installing Mojave version 10.14.0.

3) Apply the appropriate combo updater to get to the desired minor version of Mojave. The combo updaters are publicly available from Apple's website (e.g., https://support.apple.com/kb/DL1996?locale=en_US).

Can you explain how to create and use the installer for 10.14.4? I'm having the same freezing issue when I run certain applications.

I have access to the right version now but I’m not sure how to get the .app to use in the instructions from the .dmg download, do you mind explaining that?

From where on the App Store then? If we go to Mojave on High Sierra it goes straight to 10.14.5. Not the base version of it.

FWIW, You can't get Mojave 10.14 any more, only 10.14.5. The "Tech" and macafiedpc are mistaken.

Without a backup of some kind you cannot downgrade without losing data. You can however find out what the problem might be.

Please post an EtreCheck report for analysis.

So I cleared like over 126GB of storage on my Mac, did a SMC (no indication it did anything) & NVRAM reset.

And my Mac did an unexpected shutdown while typing in Chrome's Omnibar (without external display connected and I was on battery mode, but at 86% - It was shortly after my SMC & NVRAM reset). Super weird. First time it has done that. It froze before at the screensaver. So it's definitely not my storage causing it. Sigh.

My Mac has frozen like 5 times now over the last 2 months ever since 10.14.5 18F132 Grrr, super annoying! I don't even feel like working on this Mac anymore. I might go back to my old one. Such a shame. I've had so many issues with Mojave, including Finder being delayed, no Cover Flow and files appearing right at the bottom of Finder's window under 'No Date' section.

All I wanted was dark mode. :(

My 2013 Macbook Pro on Yosemite 10.5.5 is flawless. Hardly ever froze unless I pushed it really hard. But maybe only like once or twice a year, if that.

PS: I use Avast too, but I have been with prior Mojave versions without any freezes. I turned off web shield because it blocks http2 on sites.

From the abrupt shutdown (send to Apple):

Well, I don't read French but you should uninstall Avast and CleanMyMac. antivirus and cleaning programs are known to slow performance and cause problems.
