Slow Shut Down Times

[Macman45]

I have noticed a big increase in the amount of time Mountain Lion takes to power down over Lion. It use to shut down in a few seconds. Now it is taking on average around 25-30 seconds. Anyone else experiencing this?

I had the same thing on my MBa...It dragged forever to shut down. A fresh, non-destructive install of ML has cured it though.

I would not recommend CleanMyMac, based on the number of complaints that have been posted in this forum and elsewhere. As an example: CleanMyMac cleaned too much. While you may not have experienced problems yet, enough people have that it's wise to avoid it, especially since there are free alternatives that have better reputations, such as Onyx.

You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.

These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space. In fact, deleting some caches can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt.

Many of these tasks should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance.

Mac OS X does a good job of taking care of itself, without the need for 3rd party software. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.

Five Mac maintenance myths​

Ah, I see.
I wasn't aware of the risk. I just read somewhere that I should "clean" my computer once a month. But, as per your recommendation I will not use CleanMyMac. And if needed, I will look into Onyx.

Thanks!

There's no need to "clean" your Mac. I think some of this thinking is a carryover from Windows experience.

Having issues here as well... Cleaned installed, repaired disk, repaired permissions, reset PRAM & SMC (even though that shouldn't make a difference).

I saw something about Parallels causing the problem. I have Parallels installed, and notice this every time I shutdown.

They released an update earlier today though. Maybe they fixed it? I haven't had a chance to try it yet.

I currently do not have Parallels installed and I still get this problem.

I'm still experiencing slow shutdown times. Even after 10.8.1 update installed.

I was also wrong about the update... turns out my friend just hadn't been notified about the update from a week or two ago. So no new updates...

I'll switch my computer to boot into verbose mode to see if I can spot the culprit.

 

[Arizor]

In verbose mode at shutdown my main culprit seems to be:

com.apple.securityd

Anyone else?

If you're running Parallels, this solution worked for me:

1. In 'Finder', clicked on 'Macintosh HD' under Devices.
2. Double clicked on 'Library'
3. Double clicked on 'LauchAgents'
4. Dragged three files starting with 'com.parallels.' to 'Trash'. Required password.
5. Repeated #1 and #2
6. Double clicked on 'LaunchDaemons' now
7. Dragged one file starting with 'com.parallels.' to 'Trash'. Required password.
8. Restarted the system. This is the last time system takes time to 'Shut Down'.
9. After restart, 'Shut Down' took just a few seconds !

We have to wait for 'Parallels' to come up with an update fix.

This.

I just tried to run UNIX maintenance terminal command. Maybe could help

sudo periodic daily weekly monthly

My Mac Pro was taking over 1 minute with both Lion & ML.
I just removed Parallels - now shuts down in a few seconds.
Mmmmm, wonder if I will reinstall or just use BootCamp to my Windows drive, I received an email today asking for $49 to upgrade to Parallels 8..... I don't think so!

 

[ryannazaretian]

In my case, Parallels is having some problems, but I'm not sure if that is the cause. You can see all of the com.apple.launchd stuff below the Parallels errors, which is where it spends the majority of its time. It will spit out a batch, then stop for about 5 seconds, then another batch of them, and stop, for about 4 times.

If you notice, they're all the same PIDs and services. I'm not used to debugging OSX, so I'm unsure if that is related to the Parallel's errors or not.

Maybe someone with more experience can tell me?

 

[Paradoxally]

If you're running Parallels, this solution worked for me:

Parallels 8 fixes this for me, my 2009 MB Pro is very fast to shut down (with HDD), around 7-10 seconds including closing programs.

 

[aarmstrong27]

I did the Java delete described above but did not see an increase in shutdown time. I am not running parallels. I have an external HD connected and according to what I've read on another forum, external wired, or even wireless, HDs could be causing this problem.

However...

With the latest 10.8.2 build (12C35) I'm back to 3-5 second shutdowns.

Slow Times Both to Download and With Safari

Hello,

I've also found that both OS X Mountain Lion and Safari are both slow.

As for Safari, once I'm at a site, I cannot click on a sub-menu without waiting.
I need to go back to the original first time I visited the site, then visit something else.

I use Google Chrome now!

Also,even with the "new improved Safari", my Safari still crashes, but now as much as before (6 times a week). I guess that was 1 of the new 200 improvements!

Most of you are talking about reloading the OS. However, how can someone do that if you downloaded the OS from Apple? They didn't seem to offer DVD's at the time, and I think still don't.

No, Apple hasn't offered Mac OS X on DVDs since Lion was released.

I had slow shutdowns on both 10.8.0 & 10.8.1, tried to figure it out by looking at the console log, and think i worked out it was something with the internet. See if you all still get it if you turn off airport then shutdown.

I did a completely clean install last night and it so far seems to have fixed it anyway.

 

[JForestZ34]

I just have to ask a question. What is the big deal if your shut down times are longer than before? Is it really going to kill anyone if it takes a little longer. You shutting it down for a reason. Even restarting is 30 more seconds really gonna kill anyone?

I have the same issue - it's gone from ~1 sec (Lion) on my Late 2011 MBP 13 with Sandisk Extreme SSD to ~15 secs. Once in a blue moon it will shut down in around a second but the majority of the time I have the grey screen with the rotating shutting down icon. This happens even when I boot up and then shut down without opening up any applications.

Was running ML on Sandisk the migrated to Samsung830 SSD and installed a fresh copy of 10.8.1 and VmWare Fusion 5.0.1 and this started happening. it can go up to 30~35 sec whereas before it used to take 1~2 sec.

It's not about extra 30 sec, though extra 30 sec can kill someone in some other situation. Here it means something is not right or fallen out of place and needs to be fixed.

 

[MassiveAttack]

I just tested my machine and it shut down in 5 seconds. I never did a clean install or anything. My machine is totally stock running ML.

I think we are more concerned why the shutdown is suddenly taking 15 times longer to shutdown - it's not so much the duration, just the fact it has increased. There must be a reason for it and it suggests something is not quite right!

 

[inspirations365]

I had the same thing on my MBa...It dragged forever to shut down. A fresh, non-destructive install of ML has cured it though.

This solved the problem for me as well- and I don't even have Parallels! Went from ~30+s with gray screen and loading circle to Dock Disappear and black sreen in ~5s.

 

[JesalTV]

My Lion took 20-30 seconds to shut down anyway, so it makes sense for ML to do the same! Even though my MBP is v quick.

Tbh I put it to sleep 99 times out of 100, so it's not a big deal for me personally.
