OS X V10.7 Lion :: Macbook Pro Won't Start Up In 32 Bit Mode
May 29, 2012
My Macbook pro refuses to start up in 32 bit mode. At least as I believe so. When I go to "Apple > About This Mac > More Info > System Report > Software" It says "64-bit Kernel and Extensions: No" which leads me to believe (through previous research) that I am currently NOT in 64 bit mode and thus 32 bit. However in activity moniter it says everytihng is running in 64 bit mode, which to me, is quite confusing. I have tried holding down key's "3" and "2" during start up and I have tried the terminal command line for it ("sudo systemsetup -setkernelbootarchitecture i386"). Both to no avail.

My macbook (early 2008 model). Looks like my disk drive isn't working correctly; I put in a new hard drive. I went to reinstall Snow Leopard then upgrade to Lion. Ever since then my mac only seems to work in safe mode. I used my imac to load snow leopard (with firewire); and downloaded lion from app store. Is there a way to wipe clean and start over? There is nothing on the computer that I need. I keep all my important files on an external hard drive. My big concern is I don't know how to do it and second since I don't have a disk for lion will just going back to app store allow me to re-download or will I have to pay 30 bucks again.

Leopoard 10.5.2 - Quad Core Mac Pro.
I'm trying to start up in safe mode, per a recommendation from Objective Development, for a Little Snitch upgrade. I'm following these steps perfectly, and I see no indication that I'm running in safe mode. Of course, I've never seen safe mode, so I'm not sure what it looks like, but I'm guessing I ain't in it because I never see the "Safe boot at the login window".
Quote:
To start up into Safe Mode, do this:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key (the Shift key should be held as soon as possible after the startup tone but not before).
4. Release the Shift key when you see the gray Apple and the spinning gear. Please be patient, booting in Safe Mode may take some while.
During the startup you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.

Did a Shift - Command-V and the black screen showing all the startup steps appeared and it all looked good except: AFL Alart Sockwed cant update and INIT Reboot transmit failed. All else looks good. I have tried this 3 times and never go past that point. Then the screen turns off white like it does when it starts normally before the apple appears and the last time the screen went black.
I have tried starting with just the Shift Key and computer starts up but not in safe mode. I have tired starting with the OS X disk and the C key and it will not recognize the disk.I used the #1 disk since the instructions are printed on the disk. Did not work so I tried disk 2 and I get a menu to start the OS or tools. If I click on either one the screen goes white and stays that way.
computer starts fine and provides a login window, and then the desktop screen with screen saver pictures in perfect color. As it goes through starting programs it starts the same programs that is had open when the computer originally crashed. Even when I close them, before it locks up again, and I am forced to restart the same programs open up to the same place. Its like the computer is frozen in one location and will not go beyond that point. Eventually the screen turns white and sometimes black and sometimes gray.
Tech support thought it was the video card, put a new one in but did not fix the problem and then said it was not that but that it was the monitor. I said that did not make sense since the monitor and desktop icons and pictures are beautiful and clear. They then said it was the inverter board on the monitor and Apple only replace the whole thing. I purchased an inverter board and replace it. No change. The tech person said that the computer works find without the monitor connected - I will see if that is correct next. Isn't that a more systimatic testing procedure then trying parts to see if it works? Oh I did do the complete long hardware test. Took about an hour and it passed! Isn't this strange?

I have a mac book pro 17. I have 2 logins. on the main one it takes a long time and only the top bar appears. the normal icons dont appear. when i move the mouse i just get the spinning wheel and i stays like that. you can not operate anything. you have to hold power button to turn it off.Â
- if i try to log in in safe mode it does not owrk either.Â
- if i sign in as another user in safe boot, things seem to work. i suspect something is not sitting right in the main sign in.Â
I have checked the disc and it says it is fine. Â I have tried to back up but i does not seem to work, it just seems to hang too.Â

I was following the directions from the iphone dev team's blog on how to fix the DFU mode in 10.5.6 by dl'ing from Apple and installing the "IOUSBFamily-315.4-log.dmg" for Mac OS X 10.5.5 Build 9F33. After I installed it and restarted as the directions stated, the machine started to reboot and then had kernel panic on start up. Now I can't get back the start up screen. I've tried disk utility and repairing permissions but it hasn't helped. What I can do other than archiving and installing?

I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?
What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.

I've got an early '08 MacBook and an iBook G4. The iBook will only work for a few minutes before freezing completely.
I want to use my MB to get info off the iBook, but when I follow the instructions to start the iBook in Taget Disk mode, the MacBook asks if I want to 'initialise' the harddrive. What's that about?
How can I get the data off my iBook (ideally without re-installing the OS)?

My iMac G5 froze. I restarted it manually, but it kept freezing on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM.
Finally I resorted to an Archive & Install. That didn't work so I did a clean install but that didn't help either. After having done everything under the sun to it to get it to work, it will still only start up in safe mode. I even tried starting up off each of my two external fire wire drives with no luck (it froze on the fire wire screen with both drives - a Maxtor and a Western Digital). I am thinking that something on the mother board has died so that normal booting is prevented but safe mode booting is allowed.

I'm getting the gray screen when I startup. I tried using the install disc to repair the utility, but it said it cannot be repaired. I had to use a plug-in mouse instead of my normal wireless mouse to get the startup disc out on a restart. I want to now startup in safe mode, but holding down shift during startup with my wireless keyboard doesn't work. Do I need to have a plug-in type keyboard for this function to work? Can you backup files using safemode?

Running mid-2009 iMac with latest Mavericks 10.9.4.Â
DVD Player has been performing perfectly in Snow Leopard until this update to Mavericks.Â
I've tried resetting SMC/NVRAM. Reinstalled Mavericks 3 times. Tried dumping the plist too. That did nothing. I've re-set SMC/NVRAM...done the Permissions using Disc Utility.Â
I can get a DVD to load selecting the Recovery Mode StartUp disk. Then I reboot and the DVD plays fine using the DVD controls. But ejecting and trying it again - it won't play. Â

I am running OSX Lion latest version on my Macbook Pro 4,1 and can't get the thing to boot from any source. Always get's stuck at the grey screen with apple logo. Have tried all the following...
- Straight Boot (power on)
- Boot via Recovery HD (hold option on bootup then select)
- Boot via Safe Mode (Holding Shift on bootup)
- Boot via Safe Mode Verbose (Shift, Command, V)
- Boot via bootable Lion USB Key (Hold option, and choose the USB drive - not the same USB key works on my other macbook pro)
On every one (except verbose) it just get's stuck on the grey screen with spinning timer thingy. I have done PVRAM reset, SMC reset and have reseated the RAM and all to no avail. I'm pretty sure the problem was caused by removing battery at wrong time (device not responding after sleep mode started and I plugged in power - should have been more patient!)
I have a Time Machine backup but it's a bit older than I thought and very much want to get my newer photos off it before rebuilding - not that Time Machine would work in current state anyway. So what are my remaining options? Will I have to open it up and remove the HD as next step or is there anything else left to try? Can I remove the HD and connect it via a USB caddy to my existing Mac to recover info (hard drive spins and sounds ok to me)?

I have a macbook air running OSX Lion 10.7.3. I have installed Messages beta and am using my Apple ID. I also use this apple ID (as well as my mobile number) for iMessages on my iPhone. The app just stays in offline mode, I cannot get it to change to available or any other status. I am therefore unable to send or receive any iMessages on my Mac. I have to uninstall and reinstall the app several times. The status shows as offline in both the menu bar status and the preferences status. All other online service are working.

One day I was using my MBP open and external monitor hooked up. Everything was fine until the internet went down suddenly while I was using iChat.
My airport wouldn't see a network and after a couple restarts and a few resets my airport finally connected to my network. Once connected it would only issue a self-assigned IP, which obviously wouldn't work.
I was able to get around this by manually entering in the correct info but the speeds were low at best, usually pausing and stalling every minute.
After frustratingly trying get it to work, I entered clamshell mode because there was no reason at the time to have dual monitors. Once I did, viola, the airport kicked in and started working full force. It's been this way for about a month now.
My laptop is a MacBookPro5,1 with a 2.8 GHz processor and 4 GBs of RAM.
I've read that airports will have serious degradation issues if overheated and while that may be the issue, it doesn't seem to be the case.
I have smcFanControl installed and the MBP seems to be relatively cool to the touch. The fans never seem to be loudly kicking in and I have it raised on a fan powered cooling pad.
I do, though, use pretty much every port on my MBP. External monitor, speakers, both USBs, and firewire 800 are all in use, so maybe this is a resource issue or a very area specific heat issue.

my macbook pro today started to freeze at logo scrren. I tried to start it up in both safe and recovery modes but it doesn't work either. I got the system to start in safe mode only once and the scrren looked like in the attached image.When I tried printing the screen instead of taking a photo with my mobile, the image appeared to be normal (without those noisy rectangles), but it wasnt. Then itried restarting but it's been impossible. As i said i tried booting on safe and recovery modes but the circle below the apple logo appèars and then it freezes again. I read about aproblem with the graphic card similar to mine in earlier models, I don`t know if it is the same problem.Â
