AppleJack

Version 1.6

Troubleshooting/repair utility.

AppleJack overview

Developer's note: AppleJack is no longer supported and has not been developed or supported for years and years. I would not recommend it being used on any systems after Mountain Lion.

AppleJack is a user friendly troubleshooting assistant for Mac OS X. With AppleJack you can troubleshoot a computer even if you can't load the GUI, or don't have a startup CD handy. AppleJack runs in Single User Mode and is menu-based for ease of use

Using AppleJack, you can repair your disk, repair permissions, validate the system's preference files, and get rid of possibly corrupted cache files. In most cases, these operations can help get your machine back on track. The important thing is that you don't need another startup disk with you. All you need to do is restart in Single User Mode (SUM), by holding down the command and s keys at startup, and then typing applejack, or applejack auto (which will run through all the tasks automatically), or applejack auto restart (which will also restart the computer automatically at the end of the process)

What’s new in version 1.6

Updated on Jul 13 2010

Version 1.6:
  • Snow Leopard compatibility [feature 2845796] (Thanks again to Steve Anthony)
  • Improved limits on output from syslog to STDOUT
  • Simplified startup of services on Leopard and Snow Leopard
  • Fixed bug in creation of user account lists in Snow Leopard where system accounts would show up
  • S.M.A.R.T. status verification is now being done in the expert mode. I still want to implement this using smartmontools, but for now diskutil will do.
  • Blessing of Mac OS X System folders on attached volumes is now possible. This is a primitive bless, ie, it does not create boot files, but simply blesses the chosen System folder and (optionally) sets it to be used for startup on next launch

I've not had cause to run AJ for quite a few years. I did contribute a small donation, years and years ago, and I am pleasantly surprised to find that in 2020 it is still valid for certain restoration tasks. However, I'm here because I cannot complete a Catalina upgrade from Mojave or blank disk without Disk Utility, First Aid telling me there are directory faults. My Question for today is: Will Applejack work with Catalina's new separatist disk structure ?

Even though Applejack appears to still clear caches, I'm skeptical about the job it's doing, because Apple has added, deleted, and moved caches over the years. I'm sure it's doing something, but I doubt that it's what people think it's doing.

Although Applejack's website links to SourceForge for v 1.7, SF delivers v 1.6. Anybody know what's up with that?

Just installed 1.7b as per posting etc below, working under Sierra 10.12.6 - but unable to repair permissions (I suspect framework MIA due to Apple) and removing the swapfiles function doesn't work, but deep clean still deep cleans and other functions also working, so was glad I spent the 15 minutes getting this installed (1.6), upgraded (1.7b) and working. Longest time was spent triple-checking script attributes/permissions with BatchChmod to make sure I didn't have to re-login as root.

Instructions below by sickteddybear re installing and replacing 1.6 with 1.7 very good.

Just type 'applejack' in singe user mode (cmd-s) after the system text has fllled several screens and choose from specific options (1-5) or run 'Auto'.

Once done, hit 'r' to restart your Mac. sweet!

Just tested under macOS 10.12 Sierra after installing the 1.7 update described below by SickTeddyBear, and it works great. No need even to type in the path; simply type "Applejack" in Single User Mode, and everything works as expected, except for Repair Permissions, which is no longer needed anyway.

I ran Applejack. To run parts 3 & 5 to clean the Cache and the memory, you need a apple password. I bought the computer used and don’t have the Apple ID or Apple ID’s from the previous owner or owners. Can I get around this so I can run these two parts of the program? Thanks…

This really is an amazing product. 6 years after it ceased being updated I found myself in a situation where my laptop running OSX 10.11.4 and my mouse arrow lost its ability to left click on anything. rendering the input unavailable. No input devices had left click functionality. Not the Trackpad nor any usb mouse connected to it. And this was the issue across all logins. It was a bit of a problem. Now I was a seriously heavy user of AppleJack also on every computer i have managed. But I haven't even booted into it with this OS before. So I fired it up and run the remove cache routine and checked for corrupt preferences and asked it to reboot. And it did and the issue was resolved!! Quite an amazing product.

I just discovered I overlooked installing AppleJack on my new iMac running 10.10..2. I'm now faced with choosing between the formal 1.6 release from 2010 or the "untested and unreleased" 1.7 update offered by Negritude on Oct 28, 2013 (see below). Which should I pick?

Applejack and DiskWarrior were my go to utilities, I even skipped 10.7 just so I wouldn’t lose the use of Applejack. Now many people are saying that it still works through 10.10 but I have to wonder if it is completely safe and here is why: I remember with each new upgrade (vs update) version of OS X would be followed by an update to Applejack. I never upgraded until the corresponding v. of Applejack was released. And after 10.6 the developer said (paraphrasing here) he could not keep up with all the under the hood changes with each new version of OS X so he was going to stop development of Applejack. So if the developer couldn’t keep up with the continuous changes in OS X for whatever reason, and ended development for that reason, how can it possibly still be safe to use?

WooHoo! Or whatever it is the kids say these days. Just tried this on Yosemite and it works! Two caveats: 1) didn't try Permissions as that has been borked for several versions; 2) at the prompt, instead of typing "applejack" you must type the path. If you do a standard Applejack install you would type (minus the quotation marks) "/private/var/root/Library/Scripts/applejack.sh" and then hit "return". YMMV but I got the hint from several google hits.

AppleJack continues to work under OS X 10.9 (Mavericks): 1. Disk repair with fsck is working fine. 2. Clearing of caches both system-wide and per-user is working fine. 3. Validation of plist files both system-wide and per-user is working fine. 4. Clearing of the system swap file, including deletion of the safe sleep image on laptops and desktops that have hibernation enabled is working fine. 5. Automatic execution via both the regular "auto" and deep clean "AUTO" parameter is working fine. 6. Execution of additional special functions, including memory testing via memtest, is working fine. The only thing that doesn't work: 1. Repairing permissions, and this does not in any way put your system at any risk. It simply fails to start, but then AppleJack continues to operate as normal, including in auto/AUTO mode, going on to the next task. I would say that despite the fact that this script is "obsolete", and superseded by the recovery partition in Lion and above, it is still a very useful tool to keep in your Mac troubleshooting and maintenance arsenal. In particular, and I have mentioned this before, but the clearing of caches when in single-user mode is a much more thorough approach than what Yasu, Onyx, TinkerTool System, and other trusted apps provide. Despite the program being "broken", I'm still giving it 5-stars across the board, and sending out a huge THANK YOU to it's former developer, Kristofer Widholm. He provided us with an invaluable tool that kept our machines in shape for many years. Please don't consider this blasphemy, but in terms of the larger Apple and specific Mac community, all I want to say to Kristofer is, thank you for your service.

Working here on Mavericks! I did not test Permissions as I haven't trusted that in several versions. But all other functions looked perfectly fine.

I've been administering & maintaining Macs for over 20 years. I consider Applejack, and the combination of Applejack and Memtest absolutely essential for troubleshooting Snow Leopard (& earlier) machines. I can't comment on Lion or above. Yet, from this forum it looks like some have used it with success. Cheers to the developer for all his work over the past many years. It's distressing that Apple has configured the new OSX so as to render this tool difficult to update. I have contributed through Paypal to the developer and I certainly will continue to do so if someone else picks up the project. For those of us who still have a 10.6 volume, I highly recommend Applejack.

From 10.4 through to 10.6 AppleJack has save my mac more times than I care to admit. I has never crashed or failed in its task. AppleJack is quite simply the Boss. Do not pay attention to the *morons* below who gave half a star because the dev has finally ceased work on the project after years of excellent work and support - all for free. He only stopped because: a) Lion already had a recovery partition built in, and b) Apple won't answer enquiries about changes to Single User Mode. So. If you have 10.7 or above you probably don't need AppleJack and it is not designed to work beyond 10.6.8... unless you know what you are doing, leave it alone. MacUpdate should "update" their information accordingly. But anybody still running an OSX machine up to and including 10.6.8 should install this for emergencies and rate it 5 stars. Then see about making a donation to the dev...

The developer officially ended all work as of Jan 28, 2013. Read his post on Sourceforge here (scroll to near the bottom): http://sourceforge.net/p/applejack/discussion/271611/thread/e2bee929/ The source code is available if anyone wants to develop it further. That being said, if you're still using Snow Leopard or earlier, the last "official" version, 1.6, works very well. Highly recommended.
