Fast User Switching Problem (Sometimes Cannot open applications with two accounts logged in)

Hi there,

I'm using a Late 2012 21.5" iMac running Sierra (10.12.2), (though the problem has existed for some time, I believe dating back to El Capitan).

I'm running into some problems with Fast User Switching.

The main problem seems to be that after two users are logged in for a while (might take anywhere from a few days to a week) we run into a problem where everything slows down quite a bit and launching new applications gives us an error message that says something to the effect of "Cannot open this Application" new processes generally can't spawn but the computer keeps running processes that are already running, albeit generally pretty slowly.

In the past I've mostly fixed this by just restarting the computer because it seems like the fastest way to solve it, and it always seems to crop up when I or my wife have something we need to get done, This especially annoys my wife because she doesn't actually use the iMac all that often (she does most everything on her iPad but occasionally needs to use the iMac) but quite often by the time she gets on the iMac we're experiencing the problem. It's gotten to the point that she doesn't want to log into her own account because it always seems slow and unusable. I'd prefer we keep using our own login's so things are exactly as we expect them to be when we get back to the computer (I tend to leave a lot of windows and tabs open for various projects, not to mention I'd prefer not to have gifts I'm buying for her ruined while I'm doing research, as almost happened this past month).

Until today I had only suspected that the issue was related to Fast User Switching, but hadn't had time to really dig into it to try and experiment and figure it out. Today I ran into the issue and did a bit more experimenting. Because I had some time Instead of just restarting the computer I switched over to my wife's account, (which takes a very long time whenever the issue is happening, which is another annoyance), and then logged her out and switched back to my account. Low and behold I could launch new programs again.

I've gone to the console and I can see when the problem is happening but I can't figure out what the root cause is. Below is some of the logs showing what I'm seeing when the problem is happening I haven't yet gone so far as to reinstall OS X and then load our info back on from a time machine backup, but I'm not against giving that a try, though I'd prefer something less drastic if anyone has any suggestions.

Please let me know if you have any questions or need any further information.

Your Mac isn't working properly. The first step in diagnosing a broken Mac is to rid it of any and all nonessential junk, a broad category that includes any product claiming to "clean", "maintain", or "protect" it.

"Cleaning" scams are destructive in nature. It's what they are and how they work.

Excerpted from Effective defenses against malware and other threats:

Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.

Such products are very aggressively marketed. They are all scams.
They generally operate on the flawed premise that a Mac accumulates "junk" that needs to be routinely "cleaned out" for optimum performance.
Trial versions of those programs are successful because they provide the instant gratification of greater free disk space.
That increased space is the result of irreversible destruction of files, programs, or operating system components normally protected from inadvertent alteration or deletion. The eventual result will be unreliable operation, poor performance and random crashes that may not become evident for months or even years after their use, when updates to programs or OS X are eventually released.
Memory "cleaners" that circumvent OS X's memory management algorithms work by purging inactive memory contents to mass storage, which can only result in degraded performance and accelerated hardware failure.

Merely uninstalling ill-conceived "cleaning" apps, even when performed in strict accordance with their instructions (which often don't work) is usually an insufficient remedy due to the effects of having used them. Very briefly stated, the recovery procedure from having used such things is as follows, and in the following order:

Back up the Mac using Time Machine or an equivalent backup strategy
Remove the scam "cleaning" products according to their instructions, and evaluate
Reinstall macOS using macOS Recovery, and evaluate
Reinstall all other potentially affected apps, and evaluate
Erase the Mac completely, followed by reinstalling macOS, followed by reinstalling essential apps from their original sources, followed by migrating User content from the Time Machine backup.

Since the results of Steps 2-4 are almost always unsatisfactory, I omit them as unnecessarily time-consuming.

An expanded procedure for Step 5 is provided below the horizontal line. Be sure to read everything and understand its implications. Less drastic solutions certainly exist, but this one will probably result in the least amount of your time and need for constant interaction. It is also unequivocally supported by Apple's published documentation, is what a Genius Bar would do if you were to pay them to do it, and it is the exact same procedure I use given a Mac that has been affected by similarly categorized products.

To recover from the effects of having used "CleanMyMac" to modify macOS, the additional software you require and the essential files you need, follow the applicable recovery procedure below:

If you have a backup that you created prior to using CleanMyMac, now is the time to use it. For Time Machine, boot macOS Recovery, and at the Mac OS X / macOS Utilities screen, choose Restore from Time Machine Backup. Choose a date preceding the installation of CleanMyMac.
If you do not have a backup that predates the use of CleanMyMac, create one now. To do that read Use Time Machine to back up or restore your Mac
- The recovery procedure will require that you completely erase the Mac using macOS Recovery, and then create a new User Account whose contents will be empty. You will then be able to use Setup Assistant to migrate your essential documents including photos, music, work products and other essential files.
- To erase and install OS X / macOS read How to reinstall macOS.
  - Follow the instructions in that document under use Disk Utility to erase your built-in hard disk.
  - Then, follow the procedure in Move your content to a new Mac.
  - When asked how you want to transfer your information, select Transfer from a Mac, Time Machine backup, or startup disk.
  - Under Select the Information to Transfer, select only your previous User account and do not select "Applications", "Computer and Network Settings" or "Other files and folders". De-select those choices.
- Subsequent to using Setup Assistant, you will need to reinstall the essential software you may require, once again remembering to install software only from their original sources, and omitting all non-essential software.
- "Non-essential software" is a broad category that includes but is not limited to third party "cleaning", "maintenance", and "anti-virus" products.

Also I just reproduced the problem, and was able to get Acitivty Monitor running (acutally had it running just before the problem started). The "memory used" section showed only 11.46 GB, with 11.95 GB of Cached Files.

Here's a photo of Activity monitor while the issue was happening (sorted by memory usage):

Any ideas? I don't think it's a lack of RAM that's the problem...

Ok, that was in fact the solution. I checked the process limit and it was in fact 512 for some reason. I went ahead and bumped that up as per the instruction in the link below. (I bumped up the file limit a little too though I never had that particular issue but with more processes running I could see hitting the file limit more easily, especially with two accounts running correctly.) I was able to get up to 600ish processes between the two accounts, with just about every app I could possibly run with no problems.

(I didn't bump up the number as much as this article did, but bumped it up a fair bit). Anyway, if anyone else is having this issue or a similar one, check to see what your process limit is and if you might be bumping up against it, and then see about raising the process limit per the instructions below. Also, I didn't find that I needed to turn off system integrity protection to do it. Not sure why the article indicates that'd be necessary.

One last bit of warning. From what I've been able to tell, from reading the process for raising the process limit seems to change every time there's a new version of Mac OS, or at least has the last bunch of versions, so it's entirely possible the procedure to do this will be different once High Sierra comes out. I'm hoping that my changes will at least be preserved when it comes out (assuming the change the proceedure again).

Hi there, Brandonshire.
Thanks for using Apple Support Communities! It appears that you're needing to restart your iMac to be able to use fast user switching between your and your wife's user profiles. Your iMac slows down considerably and isn't able to load another application without a restart. I'll be happy to help.
Use Activity Monitor on your Mac -- Use the Activity Monitor to determine whether you need to quit one or more applications or install more RAM.

Let me know what you find and take care!

So that's not quite correct, though close.

The issue with Fast User Switching and apps not being able to open, only happens after several days to a week or both accounts being open. If I log out one of the accounts things will return to (relative) normal. I suppose it could be a RAM issue, but i'm not sure. I have 16 gigs, and I'm generally not running anything too crazily RAM hungry, (and quitting programs doesn't seem to make any difference).

The next time it happens I'll try to fire up activity monitor and see what I see, but the first few times this happened I seem to recall trying to do that and finding that I couldn't launch Activity Monitor either.

I'm having pretty much the same issue on Mac Mini Late 2014 running Sierra 10.12.4 and Mac OS Server 5.2. Now the Server is constantly crashing. It started a few days ago for no particular reason. No updates were installed immediately prior to this.

Ok, resurrecting this thread.

I actually gave up on the issue previously and just waited to get a new iMac. I was hoping that'd solve the problem. Sadly it has not. I ran into the same issue just a few minutes ago. I now have 24GB of RAM so I'd be surprised if I was actually running out of available RAM, but here are the most recent logs from when it happened.

Any ideas or suggestions? This doesn't seem like the way things should work and again is preventing us from using separate accounts.

One additional bit of information. It actually almost seems like things are worse now than they were when the problem first started (which I'll remind you was on a totally different machine, the problem has followed me from one iMac to a new one). It seems to happen faster than it used to. When I used activity monitor for the post above I was able to get the problem to start within a few minutes of logging into my wife's account. Admittedly I was able to launch a couple of things first (like Safari and Chrome) but they started having problems loading pages and new tabs almost immediately. Interestingly, it seems like every once in a while they'll be able to spawn a new tab and load a web page in it but they will go back to having problems. Occasionally while the problem is happening I can get an app to launch, but then the next one I try will give me the same "Cannot open this Application" message.

I don't think it's a RAM issue, but I am wondering if there's some other issue that's causing the two accounts to "fight" over some resources? I've tried googleing the message in the console, but haven't found anything useful.

It sure seems like some kind of deadlock as both accounts compete for some resource.

It is not surprising that the problem carried on from one mac to the other: I imagine that as you migrated you brought the applications, settings and accounts from the old mac to the new, and so you probably brought along the issue as well.

I suggest you run the diagnostic tool Etrecheck and post its report here. This will give as a notion of stuff such as launch agents, daemons, login items, that may be involved.

Try it with one account. It will give info about things that are system-wide and things that are specific to that account. Depending on what we see, it may or may not be worth running it from the other account, but for now I suggest you run from your own account, which I gather is the one most often used and where more things are likely to be installed.

Thank you. THAT is a potentially very helpful comment. I'll see about giving that a try.

However, before I go to quite that extreme a step, does anyone else see any other potential causes of the problem? I'd certainly prefer to find a solution that doesn't involve completely reinstalling the OS and essentially manually recreating my entire setup. (I'm not opposed to doing it eventually, but if there are other things I can try first I'd like to do that).

If/when I do take this step, are there any other specific programs listed in the Etrecheck report that anyone sees that I should avoid reinstalling?

It's actually not that bad, and given the alternative of selectively uninstalling various other potential culprits, that procedure I advocate is likely to result in the least amount of your time and constant interaction. It is also certain to be successful, given the fact that "cleaning" apps are capable of causing widespread corruption... depending on exactly what a user did with them while they were installed. Selectively uninstalling various programs and system modifications is best left to those with an abundance of time and / or curiosity, while the likelihood of success is low. Having (on occasion) an abundance of time and curiosity, I reached that conclusion on my own. I avoid imposing tedious solutions upon someone else.

That is the reason merely uninstalling those bad actors or reinstalling macOS is not likely to help. Follow Steps 2 through 4 anyway, because that will provide a quick answer to that uncertainty.

The essential first step is to create a backup, which you already accomplished. Then, install what you need to use your Mac. For example, you may need to reinstall Adobe and Microsoft apps, but do not reinstall "CleanMyMac", "TechTool" or the Seagate add-ons. Such things convey exactly no benefit to you. No Mac requires them just so that it can work reliably. Apple specifically designed Macs and macOS for maximum performance, while requiring minimal attention. Its reliability, security and performance can only be degraded by using clever third party products claiming those abilities.

You probably no longer need Adobe Flash Player, Java, or Silverlight. None of them are likely to contribute to the problem you described, but in general unless you are 100% certain you require any particular product for the work you do, don't install it.

The balance are up to you, but some of them remain potential troublemakers. As with all software installations, proper use, potential adverse effects, updates to them, and effective uninstallation instructions are all your responsibility.

So the reason I am asking about other less drastic solutions is that I'm not convinced that the problem is necessarily caused by CleanMyMac or any of the other programs you mention. It might be, but so far as I can tell that's just a guess on your part. Though if that impression is wrong please let me know.

This morning I went ahead and uninstalled CleanMyMac, now that I know it's generally not well regarded by all of you. So I'll stop using that. But I'm also hoping someone has more specific insight into this particular problem.

What I'm really hoping for is that someone will stop by this post and say "Oh! Error 35! I know that one, do xy and z and it'll clear that right up." Instead of what is essentially the nuclear option which is what you're proposing. It may come to that, and I appreciate the information on how to do it if it does, but I'm still holding out hope that someone will have some more specific advice.

This issue is annoying but it doesn't actually prevent me from doing most of what I want to do on my iMac. So until I have a lot of free time all in one sitting, something that drastic is going to be low on my priority list. If I can avoid spending an entire day (or more) reinstalling the OS and setting up both my and my wife's accounts (which will also involve at least a few hours of cataloging everything we both use and need reinstalled before I even start on the reinstall), I'd like to avoid it. Again, it may come to that, and if so i'm willing to do it, but it's a very big time commitment and a lot of downtime for the computer which serves a lot of different functions in the household.

Of course I've also just realized that since I just got a new iMac I'm suddenly covered by AppleCare again, so I may just give them a call and see if they can help me. (If I'm really lucky the person I talk to will know exactly what the issue is and we can proceed from there).

Thank you again for the help. And if anyone else has any specific insight or suggestions please let me know.

The salient point you seem to want to overlook is that any Mac that has ever been affected by any non-Apple "cleaning" product will no longer be reliable, until the affected Mac has been completely erased and its contents restored from sources unaffected by the alterations they are capable of inflicting on a system. The effects of using such ill-conceived junk are potentially disastrous, widespread, and cannot be predicted. Problems resulting from their use are likely to arise or reappear with every macOS update or upgrade there will ever be, and will continue to reappear until that Mac is completely erased and reconfigured from the ground up.

A Mac unaffected by such junk will work properly. Good luck.
