Mac Os Mojave freezes

I came across the same problem as yours: my MacBook Pro (retina, mid 14) didn't work very smoothly. Content frequently froze, at the same time Apps couldn't be opened but my mouse was movable while the rainbow wheel kept spinning.

After couple times' trial, I found it was the Adobe Flash.

If you uninstall the Adobe Flash, the freezing problem of Mojave could be solved (if you have Adobe Flash installed in your macOS).

BTW, I didn't reinstall the Mojave, but I tried to disable Spotlight or Siri and it didn't work. So I think it is because Adobe Flash made macOS crash.

Based on Apple & McAfee tech sessions I do know that the issue I have is related to McAfee Live Safe Real-Time Scanning function. While it's running I get a temporary freeze whenever I try to alter an Accessibility setting for any app in the Security & Privacy Accessibility list (or when a new App arrives in the list). De-install LiveSafe and the problem goes away, re-install it and the problem returns. Installing but then turning off the Real-Time Scanning function also gets rid of the problem. The Firewall function doesn't cause any issues. Automatic Updates and Scheduled Scans functions also don't cause any issues, but then they're unlikely to be active every time I want to change an accessibility setting.

McAfee have escalated this and I have a further call tomorrow. I can't be the only one out there with McAfee LiveSafe and Mojave 10.14.2. Hopefully there will be a fix, but at least for now I know I can just temporarily disable the Real-Time Scanning function while I am granting accessibility. Whether this relates to other freezing issues such as you have described I have no idea...just throwing this into the forum in case it helps someone else.

I'm experiencing the same issue with McAfee AntiVirus Plus 4.5.8, and like you I found disabling the Real-Time Scanning solved the problem of the beach balling. What clued me in was watching the Console's system.log for a while and looking for any interesting messages whenever the beach balling would occur. What I started to notice were lines like these:

Jan 20 01:05:45 xxxxxx McAfee: [98]: Alert: LogTime: 2019-Jan-20 01:05:45 AVAS: PID: 4006 : Cache: Dead Lock found Pid: 3765 holding the lock for 706.143247 seconds. Releaseing the lock forcefuflly
Jan 20 01:10:04 xxxxxx McAfee: [98]: Alert: LogTime: 2019-Jan-20 01:10:04 AVAS: PID: 4373 : Cache: Dead Lock found Pid: 4006 holding the lock for 259.096690 seconds. Releaseing the lock forcefuflly

In other words it looks like the Real-Time Scanning processes were getting hung, and a watchdog process was eventually killing them, at which point the beach balling stopped and Finder could finally finish whatever it was trying to do with the file.

I gather from this thread that there are a number of different issues capable of causing the kind of beach balling we're experiencing, so the root of the problem may lie in Finder, but McAfee definitely interacts badly with it.

Hello,

I had freezes on video playback, cursor etc.

I have checked my logs and found that:

that was always in Console on freeze moment.

And I have disabled: System Preferences -> Energy Saver -> Automatic Graphics switching

Finally 2nd day no freezes.

I hope thats help.

I tried so many things; Time machine restore, clean reinstall, SSD Firmware (No updates), New partition, Flushing caches, Resetting PRAM & Reset SMC.... etc.

However finally I resolved the problem by upgrading RAM. My ram was 8GB, it stopped on every right click on any program. However, now I don't see any beach ball after upgrading it to 24GB.

Hope it helps some people too.

So I have some good news to report finally =)... I have a iMac (Retina 4K, 21.5-inch, Late 2015) with 16 GB 1867 MHz DDR3 & An APPLE SSD SM0512G.. I think I finally found the source of my problem & it was software... For me it was Internet Protection Powered by McAfee via Optimum.. After I uninstalled that program I am going on 6 days without a single freeze and my computer is finally working the way a Mac should work =)

Hi i was facing the same problem after updating from Mojave 10.14.1 to 10.14.4, My track pad stops working the Key board stops working and the entire Screen freezes. I tried Resetting the VRAM and trying to get into the Recovery but neither the Keyboard nor the mouse would respond on startup.

So i got an external wireless mouse and an wired keyboard and was able to get into the recovery mode using those .

After that i used the Time Machine Backup and presto everything started working fine.

Tried the upgrade again and the same Problem.

So Again used the time Machine and my Mac is fine Now .

So i Have decided not to Upgrade at the Moment.

I'm Using Macbook pro early 2015.

I have been having this problem and after process of elimination and research looks like disabling Google File Stream solves the problem. Many others saying the same thing. This is a total drag as I use Google Drive all day and have to use Cloud version only.

Considering downgrading O/S so I can work as I used to.

I hear your frustrations and agree. That being said, have you applied the 10.14.1 update? It seems to resolve the problem, even though it is not addressed in the description of the update.

I tried everything but finally just reinstalled Mojave and it did the trick. Reboot and hold down CMD+R during boot up. Then follow the options to reinstall a fresh Mojave. Took about 45 minutes.

post etrecheck as old toad suggested above.

I suspect there is a memory leak in Spotlight that Apple hasn't 'fessed up to yet. Can you go into System Preferences - Spotlight - Privacy and add your Macintosh HD to disable Spotlight indexing and see if that helps? I just tried this on my system and will see if it fixes the problem. (If that doesn't solve it, just go back into System Preferences and remove Macintosh HD to re-enable Spotlight.)

That would also work, as would sudo mdutil -a -i off (although I can’t remember if that survives a reboot). I just chose to use System Preferences to make it easier to reverse when Apple fixes the bug. Shutting down Spotlight entirely seems to me personally a bit extreme when preventing indexing of my drives seems to work equally well. But any of these can be undone so it’s all good.

SSD is much faster than rotational media. I noted (somewhere in the middle of that novel) that the system hangs would still happen, but they would be shorter in duration, with an SSD.

If you're finding they're long, long hangs, it would suggest to me there's a problem in the OS's error handling routines or functions, rather than strictly something to do with the read/write process with the drive. (This is assuming it's a file read/write problem you're encountering; it may not be.)

I'm inclined to agree there's a huge problem with Spotlight for this release. I also think your stopgap measure is the optimal one: Going into the Spotlight pane of System Preferences, and adding the entire hard drive to the "Privacy" tab.

I may be doing exactly the same on that Mini in a few days, if the problems persist, until Apple drops the 14.1 update. I might also do the same on my Air. It hasn't been experiencing any system hangs at all, but RAM is flooded and usage time on battery has dropped drastically since Mojave. That is almost certainly Spotlight/mdworker related.

I solved this problem deleting "Recents" from the sidebar on the finder window, and disabling Spotlight for all hard disks, and Mojave runs without lagging, I'll activate Spotlight indexing during the night
