OS X Mavericks :: Can't Boot Mac
Jun 30, 2014
I forgot my password so looked on YouTube how to go about this. I turned off the Mac. Restarted. Went to terminal. Typed: mount -uw...Then typed: rm/ var/db/.AppleSetupDone then I typed exit to exit the program. When turning the Macbook (Air mid-2013) back on, the chime then the screen turned on with the Apple logo, then it just turns off. Tried booting in safe mode, does the same thing. Tried pressing option key then clicking on recovery partition, tries to load and fails then Mac turns off again. I clicked cmd and R and it downloaded an Apple recovery thing, tried repairing the drives, and also tried installing a new OsX but it says a newer version is installed (the latest one).
I've clearly messed something up in the terminal and now it just simply wont turn on. Is there anyway to set the terminal back to its factory settings without being able to get on to the mac? I haven't got a backup.

Just got my MacBook Air back from a certified Apple repair shop - I'd had maintenance done, including upgrading to Mavericks (10.9.3). Plugged it in, started it up and never got beyond the startup screen - Apple logo and spinning wheel after 5, 8, 10 minutes...
Tried starting in Safe Mode, but once the load bar progresses about 1/5 of the way, the bar disappears, the wheel spins and then the screen goes black.

Spotlight still wanting to reindex their mac after every restart/reboot - the finder becomes completely bogged down until spotlight finishes reindexing my mid 2011 iMac hard drive. I have tried a clean install from scratch, clearing the caches, deleting the spotlight files and letting it reindex from scratch, nothing seems to get rid of the initial lag once the desktop first appears - it happens after every restart or initial boot up….as soon as the icons for the hard drive appears, it immediately goes into "reindexing iMac hard drive" and takes a few minutes to complete, during that time, the computer is totally unresponsive to anything until it finishes. (Computer configuration = Mid 2011 iMac with 16GB ram and 500GB H.D. that has over 200GB of free space - Time machine backs up to a 2TB Lacie D2 Drive via firewire 800).

Display flatters for up to one second while doing the regular boot.Means it gets blue with Apple logo bright - like a negative of original screen.Was not observed with Mavericks first releases .1, .2.iMac Late 2013, 27 inch, NVIDIA GeForce GT 755M 1024 MB.Again possibly a problem with SMC and it's reset as first solution candidate,or rather graphics?

Updated to OS X Mavericks last week. Ever since, it has been experiencing boot problems.
- If I restart my Macbook Pro (2011 13", lowest model), it will sit at the grey screen with apple logo and spinning grey wheel forever. I notice that my HDD is NOT running (no clicking / writing sounds)
- If I restart with a PRAM reset or holding down option to select Macintosh HD boot, the hard drive starts to run (I can hear it) and it boots successfully... it takes 5+ minutes to boot up. The grey screen with apple logo is presented on my screen for about 4 minutes, then the login screen shows up but I cannot move my mouse or select a login user for 30 seconds. After this, I can log in succesfully.
-Also, switching users takes 1+ minutes. Clicking "switch user" freezes my screen.

Macbokpro 2.2ghz i7 - 4g ram...10.9.3
All of a sudden our MBP will only boot in safe mode. After reading about this there was some answers about the shift key being stuck which makes sense since i couldnt login to my user because its a 5 lowercase PW. i got a usb keyboard and with the shift key pressed down i can now enter my lowercase PW. I took both shift keys off and cleaned under them, there was barely any dust even. Still stuck in shift somehow. i tried to reset the PRAM by booting with Option-Command-P-R with both the MBP keyboard and the USB keyboard with no success. it only brings me to OS X Utilities where i can restore from time machine, Reinstall,
When i upgraded to Mavericks i did make a USB installer of it. I cant remember if 10.9.3 is the version i downloaded. When i check the USB i know i made it on Feb 12 2014, the day i downloaded it, and its version 1.3.40.

I've just set up a FW800 SSD to use as an external boot drive for my 2011 iMac (mainly to speed up start-up).
I wanted to find out if I can direct the external boot to access the program files on the internal HD as a default. Or do I need to reload them all again on to the new partition/drive? My main concerns are that some are 1-time registration programs, plus I don't want to fill the smaller SSD too soon...

I'm trying to boot up my late 2013 15" MBP (shipped with Mavericks) using an external startup disk running Mountain Lion. I really need to use the FCP iChat Theater feature, as I need to do some long distance editing. The startup disk works just fine, I checked it on another computer, but when I restart my Mavericks mac and choose it as the boot drive, I just get a grey screen with the universal "no"symbol (circle with a slash through it).

I have an iMac from 2008. It got stuck in an infinite boot loop, so I took it to the local Apple Store. After they ran some diagnostics, it was determined that it was either a bad Logic Board, or Hard Drive. Because of the age of the computer, he said he was unable to work on it. Said it was "legacy" or "vintage"or something. So he gave me a little direction on how to open it up, and how to get to the hard drive (I'm fairly comfortable working on hardware replacements). Using a borrowed hard drive, I was able to boot to a Windows XP install (this was an old hard drive out of a Windows PC), which tells me that the original hard drive is shot.
So I am going to purchase a new Hard Drive this weekend, but I am unsure how to install Mavericks. This is the only Mac I have access to, so I cannot use another Mac to create a bootable USB drive or CD/DVD. Mavericks doesn't come with a disc, so I cannot use that. Snow Leopard is the newest OS disc that I have, so I could use that, but was hoping to just do a clean Mavericks install instead.
I have a Time Machine backup from less than 2 weeks ago. Is it possible to use that backup to install the OS on a new, clean, hard drive?
Is there a way on a Windows computer, to make a boot USB drive that I can use on my iMac? Or am I better off using the Snow Leopard disc, and then use the App Store to update the OS?

I replaced my beloved 2009 Mac Pro Nehalem with a brand new iMac 27" with Core i7@3.5 Ghz, 24 GB Ram, GeForce GTX 780M and a 3TB Fusion Drive.Big problem: the boot time is 2 min and 48 seconds, yes 168 seconds.I used Migration assistant to configure this machine from my last MacPro TimeMachine backup.
Apart from boot time, the iMac works fine and the disk tests with Blackmagic show a writing speed of 300 mb/s and a reading speed of 580 mb/s.. Nothing else seems wrong, but the boot time is terrible.

It takes really longer time to boot up. Eventually it gets boot, but i am unable to access Mail app. Sometimes the booting is faster. In this case, i can use the Mail app. I tried to shut down, restart many times, but the boot up takes longer time or even lesser.

I have a macbook pro 15-inch, Early 2011 running osx 10.9.4. I have a SSD hard drive that i installed myself a year ago and hasn't shown any defects. Its a 120 gb OCZ-AGILITY3.
My macbook will only boot in safe mode nowadays. I have done a complete erasion of my hard drive and installed osx mavericks twice already. After the installation the computer will safely go to the desktop. But if i then do a reboot it won't get further than after the first apple logo, sometime the turning wheel will pop up, before turning off and trying again. i have tried resetting PRAM, I have tried resetting SMC, i have tried avoiding SMC (with big fan rate), but all with no success.
I have done a complete hardware test (the longer one) and it showed "no troubles found".
My guess is that the problem is with the battery. My computer won't run anymore without the adapter, when i pull the adapter out it either stays on for a while before just turning off. Without having it plugged in it won't start. Is it possible that during normal start up there is some kind of communication with the battery that can cause this?
I ran a diagnostic shown in this thread (Will only boot in safe mode) and included it in this post.

I have a Macbook Pro Retina which cam with Mountain Lion installed, and I want to upgrade to Mavericks. However, I have a need to run some apps in Mountain Lion, as official support for those apps will not go past 10.8.5 (Avid's Pro Tools 10) and I need to be able to open archived projects.
I also wish to clean install both operating systems fresh, and do a stripped ML partition, with bare bones essentials, on the smallest partion possible. Mavericks will be the main system, and ML won't host user data, only the legacy apps. I am fine with erasing my 500GB SSD.
My current process is to install ML from the recovery partition, and use disk utility to partition before I do, then install Mavericks from a bootable USB (already made).
So my questions are these:
For ML:
1. What size partition is the minimum necessary to install ML, plus the apps and run without hitch? The legacy apps will take maybe 4GB.I want this as small as possible.
2. When I do a fresh install of ML, what apps can safely be deleted without affecting the system?
For Mavericks:
When migrating my old user account to Mavericks, I don't wish to migrate the apps, just the user settings and the data. I will make an entire backup of the user directory on a separate drive before I start this process, as well as a Time Machine backup. I then plan to migrate the account settings and data, but manually reinstall the extra apps. The reason for this is I have a lot of third party apps, and some are trials I decided to uninstall, and they all leave junk behind.
3. If I import the user account settings and data only, what cruft or orphaned files should I be aware of?
4. Are there options to cherry pick the settings that are migrated?
5. If I manually copy, for example, the mail folder, iCal or messages folder in my user library, and place it into the appropriate user folder in the new account in a worst case scenario, will there be any drama I should be aware of?
Lastly, a question of Apple ID's/iCloud:
6. Before doing this process, should I deauthorise my iTunes account, or will that be fine when migrated anyway?
7. What will happen with my iPhone when I sync to a fresh install on mavericks, will it attempt to wipe my iPhone, or is that part of the user data that is migrated?

My Macbook Pro (10.9.3) wouldn't boot up. I'd get the gray spinning progress indicator along with a gray progress bar which would get about 10% through and then restart.
I booted into recovery mode and run Disk Utility to repair the disk and got a message saying can't repair, back up your files.
So I took the HDD out and mounted it as an external drive on my Mac Mini (10.9.3). I got a message saying it's read only and I should back up my files. I can browse to my users directory and see all the base folders (Movies, Music, Docs, etc), but there's a red no entry icon on all the folders and accessing them through Finder shows they are empty.
I browsed the files through Terminal as super user and can see the files. I can also copy the files through Terminal. However, after copying a test directory some of the files are read only and others are still no access.
So the question is, how do I back up these files and maintain permissions?

I have a mid 2011 27" iMac that is taking longer than 3 minutes to boot. I've tried turning off everything in the start up menu, but that hasn't worked. In one of the other questions like this, Linc, I believe said to go to terminal and post to questions the output showed up in Text edit, and I have posted them below:
Step 1:
Loaded kernel extensions:
com.logmein.driver.LogMeInSoundDriver (1.0.3)

I am running Mavericks 10.9.3.
I always quit out of all apps before doing a shutdown. I make sure that nothing, except Finder, is running when i shutdown. And, I do a full shutdown, not just sleep.
Yet, occasionally, the apps that were running before I quit out of them will restart when I turn the MacBook back on.

I've had my TIme Capsule for a few years now. Last year I decided to self upgrade the internal HDD to 3TB to actually fit back-ups from my two mac's at home. On my MBP the boot drive failed. It's unfixable unfortunately. how to restore full system on a new HDD on my MacBookPro from TimeCapsule, after boot drive failure?
how to connect the laptop with clean/ empty HDD to MBP and make it boot and install it all from Time Capsule. Moreover, I am not sure how to connect it to Time Capsule, so that it doesn't take 3 days to restore.There is both an ethernet port as well as USB 2.0 one too.
That 'old' boot driveis still barely running, I wanted to hand copy at least my iPhoto Library of 110GB in size, but it just keeps crashing, as the file is so big. I mean, I should have it all back-ed up on TimeCapsule,

During the boot-sequence the screen of my Imac 27" flashes green (once), then returns to normal. This does not happen when I boot my Windows (Bootcamp) partition, so I assume this is some kind of OSX driver error. This started to happen only after I installed the latest patch (10.9.3). How to get rid of it ?

MacBook Pro, Retina, 15-inch, Late 2013
OS X Mavericks 10.9.5
USB 3.0 External Hard drive
I am currently using an external drive for my user storage. Right now I log in with a separate User account to mount the drive, log off, and then log in with my user. I am trying to remove the extra steps so I can boot my Mac and log right in. I have not found any method that pertains specifically to Mavericks, and all of the methods I have tried for older OS versions do not seem to work properly.

Model Identifier: MacPro3,1
Processor 2 x 2.8 GHz Quad-Core Intel Xeon
Memory 16 GB 667 MHz DDR2 FB-DIMM
Graphics ATI Radeon HD 2600 XT 256 MB
Software OS X 10.9.4 (13E28)
Boot ROM Version: MP31.006C.B05
SMC Version (system): 1.25f4
This is the first time I've encountered this. Upon cold booting the machine it went directly to the legacy Mac OS X Server login screen from before the upgrade to Mavericks. It would not let me login with current credentials. I had no choice but to hard power off. It returned to normal operation on restart.
It could be a possible bug.

My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.

My Mac Pro main boot drive us encrypted. I booted into recovery mode the other day & it wouldn't let me boot back o my main drive. Now upon start up I can't enter either recovery mode nor safe mode nor chose the main drive to boot from. I'm absolutely stymied in what to do.

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM
In the second week the boot up times became very slow.
I would turn the machine on and get the chime within 5 seconds or so.
Then just a black/blank screen.
Eventually after about 10mins I would get a white screen then it would boot up normally.
Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).
I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.
I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.
But now when I switch it on just darkness.
I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.
