I had a similar mounting issue and that seemed to fix it.@sevimliClick on the link in Step 1 and choose your machine from the list there.For example, after clicking the MacBook Air section, it shows listing the various MB Air versions.@Queen6Very true, it is meant to work as a security feature.But now it is an exposed security flaw. Maybe Apple will take note of my circumvention, and this might lead them to patch it up.
Therefore making it more secure for everyone. But in the mean time this guide can help the people truly in need. Click to expand.Sadly most likely those that have helped themselves to someone else's Mac, it would have been far more prudent to have reported this to Apple via their feedback channel and not help those with criminal intent.People who have a 'true' need will simply contact Apple or their authorised retailer, those that don't want to likely have other reason predominantly no proof of ownership. You might want to reconsider your post, you may help a very few individuals who have a genuine issue, however by far the vast majority to profit from this post will be those looking to unlock someone else's Mac, how would you feel if it was your machine?

Click to expand.You has a point. But don't forget thousands of people out there who got locked after Lion for no reason like mine and people who got locked because of icloud glitch. I bought mine over sea from an authorized dealer, there is noway to find the receipt from years ago.
Brought my MBP to apple, they wanna charge me a few hundreds bucks for a new logic board! Funny, they said my logic board is 'toasted'!
You might have the money to keep up with that BS, but i don't. Other people in similar situations don't. So please stop playing guilt trip on the guy who trying to help like that. @Queen6 @iDesigner2You both have valid points, but let's keep this thread on topic.I'm open for discussion on the topic, so feel free to make a new thread in the off-topic section and invite us there to discuss the issue.@iDesigner2I'm not sure what the Lion upgrade situation is right now. But to my understanding the PIN code is stored on the Hard Drive, and the firmware gets set into lock mode (independent of the hard drive). What might have happened is that the upgrade corrupted the partition. If so, then there would be no easy way to retrieve the code.
Another assumption is that the firmware will allow you to boot from any primary drive. So in theory, you can install a borrowed working drive, run a firmware password retrieval from the OS, unlock the firmware, then re-mount your original drive, and re-install the OS.To test this theory, first try to replace the original drive with a working drive. If it boots to the OS, then things will be much simpler. You'll have 2 choices from there:1. Use firmware password retrieval tool and unlock the firmware to have it back to factory state (not sure how it works, never tried).2. Re-install the OS to the original drive from another machine and continue your business while having a locked firmware.If it goes to the lock screen with a working drive, then another theory is that the firmware writes a PIN code to any drive installed.
If so, then run that drive through my guide and find the PIN code.Caution. I don't have any external confirmations that this method works yet. So I would advise you use an auxiliary drive or at least backup the files of a primary drive if you must use it.TL;DR try to boot the locked machine from a working drive and let me know what happens. Hi, I have discovered an easy way to remove the system lock pin code off of any Macbook, Macbook Pro, Macbook Air, iMac or any other Apple computer.1. You will need a OSX86 (Lion or Snow Leopard) disk aka Hackintosh.hehehe!!!2. Insert the OSX86 disk into your Apple computer.3. Hold down the Command + C keys on the Apple keyboard.5.
OSX86 will automatically load Mac OS X setup6. Click on Utility and select Firmware Password Utility7. Create a Pin Code then click enable, then save.8. Go back to Firmware Password Utility enter current pin codethen disable.9.
Reboot Apple Computer10. No PIN CODE will be present11. Install MAC OS X as usual. Click to expand.@iDesigner2Back to your situation.
If you have the flashing the question mark, then that usually means that the firmware cannot find a working OS. Obviously that is not true in your case as you installed it on a frsh drive. So I'm guessing the locked firmware checks for a drive with a locked OS configuration, or at the least an iCloud account.
Did you take the time to setup iCloud on the new drive? If not, then I'm thinking you'll have to do your best to match the configuration on the new drive with the old drive's iCloud configuration.Another thing that I found when looking around is to start in Safe Mode. With the locked drive, hold 'Shift' immediately after power on and it supposed to do a disk check. I'm guessing you'll have to do that from an unlocked Mac.Let me know if you get progress with any of these methods. So for the past week, I wiped clean my new HDD again. Reinstalled Lion. This time i set up a new icloud account with my GF's 13' MBP and serial.
Put it in the lock MBP. Same thing happened, folder with flashing question mark.
So i guess the locked HDD should have some key data that match the locked bios in order for the locked MBP to start booting to the ACL lock screen.I also tried putting the locked HDD to my GF's mac. Surprise enough, it boot to the screen that ask me to repair the HDD or reinstall lion with the CD, etc. Just like you boot from a bad HDD. So i tried repair HDD option.
It did go through and fix a bunch of problems but still can't boot, can't access from either Mac/PC. But at least i can assume that some sort of data is still there. I'm trying everything i can think of to get whatever left on the HDD out.I wanna try the reinstall Lion option but would it erase the icloud lock file? If so i would be out of luck.Now, for the new HDD with fresh Lion and new, good icloud, should i try using find my mac and lock it down with my GF's Mac, then put it in the locked Mac? Honestly i really don't wanna go there cuz digging around the net, i saw countless of people who tried the feature with a set of code as easy as '0000' and still bricked their Mac's!
Heck, mine got locked without me even touch that damn feature.Also, I stopped by another Apple store yesterday just to try my luck. Same old answer, either proof of purchase or new logic board.
But i noticed one thing, i was there for like 90 minutes and there were 4 Macs came in for the same problem. All 4 got fixed cuz they still have receipt. Only 1 Mac Pro tower got hold till next day. The other 3 laptops, not sure what model, got unlocked on the spot. One case took the guy less than 5 minutes. If you have to sent the serial in to hub, verify all the info, hub generate key file, send it back, copy it out on flashdrive, then unlock, it could have been way longer especially during this time in the middle of IP5 hype.
It got me thinking if there is a jumper on the bios or something to zap its memory, or even better a default code or key combination to unlock? Keeping my fingers crossed.If you come up with anything else, please let us know. Thank you very much for helping people out, Excitewalk. If you reinstall Lion, then as far as I know, it will render that file inaccessible.
Your best bet would be to do your best and recover the data from that drive.I'd recommend Stellar Mac Data Recovery. It runs from a Mac environment, so if you use that, then you'll need to run it from the working Mac. You'll also need an enclosure or adapter to connect to the locked drive externally to run the recovery on it. I assume the data must somehow be readable since the lock can differentiate between the two drives.I would not risk locking the working Mac yet as we have no idea if it will let you unlock it afterwards.If recovering the data does not work, then I hope you will be able to provide proof of purchase for the working Mac.
Since that would be next up in the options for generating the lock files.Thanks for sharing your experience at the store.By 'hub' I assume you mean something like offsite Apple servers. It could be possible that they can complete that operation in less than 5 minutes. But I'm not claiming that it is the way they do it, and I do hope there is a jumper or a master unlock code (heck, even a combo of the two).I would love to try and reverse engineer the lock system to figure it out.Unfortunately I don't have a personal Mac. The one I originally did this for was a friend's of mine. Maybe next time someone has this issue in my area I can test things out further and figure out a 'soft' unlock.
Aug 23, 2018 The only possible hiccups I onticed throughout my progress was none of the mods having Meta files, but otherwise the game itself works completely fine. Should I be doing something besides starting the Mod Enabler and then starting Sm4sh to get mods to work? The mods are all just recoloured skins, so I wouldn't imagine it's breaking the game. Jun 22, 2017 And that is how you install Smash 4 Mods directly onto your Wii U! For a little tip, if you want to disable mods for Smash 4 after booting the application, just go into System Settings and exit out of it to disable the patch SDCafiine has without rebooting your console. Also, be sure to keep your SD Card in when launching this app. Installing smash 4 mods.
Click to expand.I tried this method on my early 2011 macbook pro 15 with thunderbolt and this does not work after reading countless forums and guides i think the method your recommened works on previous edition macbook pros ( Not greater than the year 2011).@ Excitewalk thanks for working on this issue im testing the method you previously posted and am having some serious trouble. I'm using stellar mac recovery and running raw recovery from that. As previous post state: finder is not recognizing the external hard drive but disk utility is but wont mount it. I'm running this procedure on a 2008 macbook ( unibody).Any suggestions what to do with stellar? When i run quick recovery and other methods it says no data could this be a result from removing the stick of ram?a reply would greatly be appreciated.

NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.If you experience issues related to these settings or others, resetting NVRAM might help. For example, if your Mac starts up from a disk other than the one selected in Startup Disk preferences, or a question mark icon briefly appears before your Mac starts up, you might need to reset NVRAM.
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart. On Mac computers that play a, you can release the keys after the second startup sound. On, you can release the keys after the Apple logo appears and disappears for the second time.If your Mac is using a, this key combination does nothing or causes your Mac to start up from. To reset NVRAM, first turn off the firmware password.When your Mac finishes starting up, you might want to open System Preferences and adjust any settings that were reset, such as sound volume, display resolution, startup disk selection, or time zone. If you're using a desktop Mac instead of a notebook, and settings such as sound volume or time zone are reset every time you shut down and unplug your Mac, you might need to replace the battery inside your Mac. This small battery is on your computer's logic board, and it helps NVRAM retain settings when your Mac is unplugged.
You can take your Mac to an Apple service provider to replace the battery. If you experience issues with sleep, wake, power, charging your Mac notebook battery, or other power-related symptoms, you might need to.
