DeferredInstall folder inside my System folder?

Hi!

Have you discovered something more about that folder?

I've noted it recentlly, and in fact I've discovered it was created just few days ago, don't know why....

Tk very much! 🙂

Same for me: I discovered a DeferredInstall folder after migrating automatically from 10.5.8 system to my 10.7 brand new computer and don't have permissions to enter in it. Changing the permissions It looks there are some important files in that DeferredInstall folder (for instances coreservices) and I'm a little bit scared. Cannot find any information on internet.

I think the user template with prohibition icon is totally normal. Any computer got that one.

Could somebody help on the DeferredInstall folder?

Hi, I've just found the same folder in my system and it says it was created within the last few days, and also all the internal folders were also created at the same time ?? I can't find any info anywhere about it except here, which is strange ?!? I'm tempted to just delete it and see what happens, but ?!?! The only software I have been using intensively lately is Capture One Pro, and this won't boot up today, which makes me think they may be related. The only other thing I can think of is that I use a proxy server to watch the BBC.... hmm, any thoughts ?

So.... I couldn't wait for a response and went ahead and deleted it....... mainly after I'd noticed that they were just duplicate files and folders that were created more recently. I restarted and everything is back to normal and Capture One Pro has booted up. Now of course I'm paranoid that my system was hacked in some way shape or form, but I doubt it... (although there is always those niggling thoughts) It seemed that a lot of the files within the folders were security based so I wonder.......... Anyway, I am curious however to what it was and why it was created, so any more info would be appreciated.

So it looks like it is not due to an automatic transfer from one computer to another one, right?

Good to see that deleting this folder looks like a good idea but like you I'm quite scared in doing that!

Yeah, I haven't transfered from anything to anything......it just mysteriously appeared.... but it is all working fine now I've deleted it, in fact if anything performance overall seems marginally better, but that could just be wishful thinking. By the way I'm running a Macbook Pro 13" 2.7 Ghz Intel Core i7 10.7.2 .

Good to know! Thanks!

Still would like to understand when and why this folder is created.

Let's see if somebody got an answer...

Same for me: buyed my Macbook Air last autumn, with Lion pre-istalled.

I swear that the folder wasn't there at the first boot... But your computer run slower after deleting it?

No, actually it ran a lot better after deleting it and I haven't had any problems since........ How weird..... I just looked in my system folder and it's back ?!?! What ? OK, I'm deleting it again..... I'll let you know how I get on.... It says it was created 2 days ago....

Ahah.. I can't beleive it... 😁

Ok now I'll try to discover what there is exactly inside... I'll let you know!

ya, i also also had the same problem. And one more thing i feel so weird when my startup disk mentioned my startup disk is getting full but somehow i never download something that stranger.then i try to check my capasity disk that have been used. almost 495GB and only left around 4GB that still available. i need the answer why it happening to my laptop. can some tell me why.. i really worried about it cause it non stop increasing

Like most of you, I just discovered the "deferredInstall" folder in my System folder.

My first observation is that it is very small: about 250 mb for the whole thing, so space is not an issue.

My second observation: I logged into my computer as root to see the contents of the folder, and here is my best guess as to what it is. Mind you IT IS ONLY A GUESS, but not an unreasonable guess based on some of the files I saw in the sub-folders.

Apple is working to impliment "sandboxing" as a security measure. As I understand it, and I admit that's not very well, this isolates applications into their own space and protects them from corruption from other applications. It appears to me that what is in the "DefferredInstall" folder are components needed for the sandboxing feature when it comes available. The files include newer versions of various pref panes and other files that would normally go in the /System/Library folder. Several of them specifically have the word "sandbox" in the name, and many others have security-related names.

As I said, it's only a guess. Take it with a grain of salt.

i have a similar file. it was created last night while i was installing a large virtual synthesizer program (omnisphere). i woke up this morning hoping to run omnisphere and there was no trace of if. it loaded 50GB of sound files ect..... somewhere but i cant find any of them anywhere so i was thinking they might be in there. it wont let me open it and it doesnt show how large it is.............does anyone know how i can get in there or at least see how large that folder is?

thanks

I found this thread while googling for information about the deferredinstall folder. Though no one seems to specifically have a verified answer in this thread let me take a stab at it for anyone else landing here. I was in the middle of working on a project when an Apple dialog appeared saying that Apple's software updater was ready to install updates. I thought I had turned off automatic updates in Lion 10.7.5 but there it was. So I deferred it by clicking on the Later button.

A few minutes later I noticed the appearance of a DeferredInstall folder in the Finder, with a lock on it.

I have no verified proof but I think it its a reasonable guess that these are the updates to Apple Software that I deferred.

Note that I happened to have my System folder open at the time otherwise I'd never know it was there.
