Lion Boot Problem on MBA

Running Lion with no problems since the first weekend it was released. Running on a Gen 2 MBA. Just restarted and its hung at the Apple screen with spinning icon. Went into recovery mode and verified filesystem and permissions. No luck. Any ideas?

Hi Joe,
     Two thoughts,
     Upon boot, OSX will do some system level software updates that can take longer then normal and sometimes these don't release control back to the boot process. It is rary but I have seen it a few times over the years.
     Secondly, If the system came across an issue that was disruptive, the safe boot process will do a deeper FSCK command and will repair certain certain drivers by discarding and loading only the basics in default configurations to boot in a more native state. Then after the next boot it loads fresh copies of many objects & preferences.
     There is a log document that may give you the answer if you can pin-down the exact time of the boot hang, But it can be a lot of tedous work reading it.
     OSX is generally self–healing in most respects.

Lost boot problem os x lion 10.7.5

i suddenly lost my OS X lion 10.7.5 on my hard drive, my macbook cannot boot again but my data is still on my hard drive question : please can someone give me a clue how do i fixed my boot problem.. thx^^

Try starting up your Mac while holding down the Command + R keys so you can access the built in utilities in OS X Recovery to repair the startup disk if necessary or restore OS X.
You can restore from a backup using Time Machine in OS X Recovery.

Missing Mac OS X Lion Boot Camp Software drivers

Dear Community,
Having just completed a smooth installation of Windows 7 on my 2011 Macbook Pro, I was quite surprised to see that the wireless and ethernet connections didn't work. The computer did not even find any possible connections and I'm missing Wireless Adaptor or any such sort of devices in the device manager.
Now, my first bet is that I'm missing a driver installation. So after having looked on the internet for some guidance on where to get the drivers, it comes down to me using the installation DVD that's included in the package in which the mac came. But no such DVD came with the package, since Apple has decided not to ship physical DVDs anymore.
So my question is, how do I get these drivers?
I see under //support.apple.com/kb/HT4818#12 that the Atheros 802.11 Wireless, Broadcom Wireless and Marvel Yukon Ethernet are all drivers included in the Mac OS X Lion Boot Camp Software, but then why don't I have them then?
Many thanks for the, hopeful, fine answers!
Best regards,
Tim

But everything else got installed and hardware abstraction, Boot Camp control panel and other drivers and services are now present and running?

Usually you need to establish a wired connection.
And it is a problem for some, definitely.
Boot Camp 4.01 or later will enable those devices but you may still need to find appropriate drivers too. I don't know why but audio and graphics are also issues that the user needs to attend to and is not 'spelled out' that you will need those as well.

How do I prevent the Lion boot partition from being reformatted when using boot camp?

Under Windows 7, Computer Mgt, I shrink the C drive to create another drive. When I right click on the unused drive to format it, 200MB Lion boot is formatted and assigned a drive letter F. But I did not tell Windows 7 Computer Management to do that. I clicked on the unused 170GB space to create it as F, I did not click on the 200MB Lion boot partition at the front of the list.
Now I have to take the computer back to the Apple store to reinstall Lion for me.
I tried this twice and it happened twice. So now I need to go back to the Apple store a second time for help on the same problem.
Would the 200MB Lion boot disk at the front be safe from reformatting if I first made it drive letter F, and then made the new drive letter H at the right side of the drive list in Computer Management? Also, there is an unlettered drive between the Lion drive E and the Windows 7 drive C. Should I make that G prior to formatting drive H?
By the way, I did this on another MacBook pro that was using Snow Leopard, following the same procedure, and had no problems. So could a different version of Boot Camp be the issue?

I just found an older question similar to this one that you also replied to. It was from 2012 and never solved. The only things I am using in my set up is a male quarter inch cable from my guitar to my interface, a USB cable from my interface to my computer, and headphones from my interface to my ears of course. Just like in the other question I found I have everything in the Audio MIDI Setup of the computer set to use the interface as input and output and I also have everything in garage band setup to use the interface as audio input and output. Any new track is recording the metronome and any old track that is being played in the headphones. No external speakers are being used for monitoring and no microphones are being used.

Macbookpro a1297 boot problem

I bought an old macbook pro 17 inch a1297 and later found that it did not have hard drive. So I installed a new blank hdd n installed mountain lion. Laptop works fine but with a boot problem. I always have to disconnect the battery connector from the board and reconnect to get it worked. If I do not do this, laptop keeps giving start up tone.
Even when laptop goes to sleep mode, it does not come up. Please help. I will be very grateful.

Hold the option key when powering up. You should then be able to select Windows to boot.
You should also visit the Boot Camp forum here. http://discussions.apple.com/category.jspa?categoryID=237

Lion boot hangs at point logon prompt should appear

Lion boot hangs at point logon prompt should appear. Unresponsive to mouse or keyboard. Mac mini 2007. Touching power button briefly puts machine to sleep. Hitting key or wiggling mouse then wakes machine and logon proceeds normally. Has happened every time Lion has booted. Never had problems with SL. Fix needed!
TIA,
--Beman

Same issue here, not always but after entering logon password it will hang with the spinning icon. I have to power off then reboot.
Only since Lion upgrade!

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?
Is this because of hardware changes? Or firmware changes? Or is it just and Apple Inc. administrative fiat?

@Steve Holton: Sorry Steve, but you're wrong about that one . I'm using 10.8 (purchased and downloaded) on the internal HD of this MBP8,3 (2.2 GHz, 17"), and I am also able to boot into 10.7.4 and 10.6.8 from external FW800 partitions.
However, I DO have problems with my MBP9,1. It came with 10.7.4 installed and ran fine. Then I purchased and installed 10.8. It ran fine but could no longer boot from 10.7.4 on an external partition. I then reinstalled 10.7.4 on the internal HD and discovered that it is still unable to boot (even 10.7.4) from an external FW800 partition.
One of Apple's Senior Support Advisors has done some remote troubleshooting but the case is still open and unresolved. An earlier Apple Support case suggested that when, I installed the downloaded copy of 10.8, there had been a "firmware update" (behind the scenes) that is now causing the problems with booting from my external partition(s). This apparently is "a bug": it is not what is supposed to happen.
So - I believe - "the problem" really has nothing to do with hardware capability. It is strictly about Apple's strategy for "managing its future customer base". If you don't like it - use something else - I am seriously considering Ubuntu as an alternative.
If there's a hidden caveat in all this it's probably "Read Appple's Licence Agreement VERY Carefully".

Mountain Lion WiFi Problems (recap)

Folks, wanted to recap this as I am finding the problem much more broad than my original post (here: https://discussions.apple.com/message/19123146#19123146). Here's my setup:
MacBook Air 13", Mid 2011
Mountain Lion
Wifi Problems, cannot connect to open wi-fi and Sprint hot spot.
CAN connect to Time Capsule (at least I could before I started futzing with my setup while on the road)
here's what I've done so far:
Reset SMC
Zapped PRAM
Reduced MTU to 1300
Set hotspot to 802.11g only
Set IPv6 to Local-link only
Set up a new user account, no connection there either
Repair disk
Repair disk permissions
Removed WiFi in networking control panel and re-add.
Remove the network from control panel AND remove keys from Keychain
What I have not done but will try later:
Reinstall ML
Disable WMM
Observations:
ML seems to think there is a connection to the wi-fi, but it can never get an IP address
Using a static IP on the network doesn't help the problem
My hotspot never really registers the MBA as a connection

Tell you what worked for me .. finally.
Had two Apple technicians on the case - over the phone. Have to say, those guys are awesome! - with patience of saints! But to the point! As there was nothing obviously wrong with operating system, they promised to call me back the following day but suggested talking to my Internet Service Provider about the router (D-Link router). The ISP remoted to my iMac and logged into router site and changed channel selection from automatic to manual. He chose channel 13, and suddenly my MBA connected and has been connecting smoothly ever since. The reasons I had problems was that there was over 10 available wi-fi networks in my flat, some of which showed as having stronger signal than my own. The ISP guy told me this, increasingly, becomes and issue, especially in blocks of flats - the ether is filled with wi-fi networks to the point of saturation. He also said, his choice of channel 13 was just a fluke and it might turn out I'd have to change it again.
So, although the problem is now solved, there still remains this one nagging question: Why did the wi-fi connectivity zonked right after Mountain Lion upgrade?

K7N2 Delta-L: Strange cold boot problem & solution

My K7N2 Delta-L has a problem cold booting when the vcore is set in the bios at 1.65v of higher. After a cold boot, you get a blank black screen. I noticed that even if you run at default speeds but set the vcore to 1.65v of higher the problem still occurs. There is no problem rebooting however.
I found the following solutions:
1. After you power up and get a blank, hit the reset button.
2. Don't unplug your PC. My PC is connected to a AVR and after I power down the PC I usually turn the AVR off. If i do this, than the computer will have a booting problem if I try to boot it up 30 minutes later or so. Now if I don't unplug it/power off the AVR than everything is fine.
I don't understand why it acts the way it does though.
Does anyone know of any other solutions?

Have you cleared the cmos. If you do be sure you have the power turned off don't move the cmos jumper with the power on.
I found that turning off power at power supply and unpluging, than turning on the computer the fans will spin just a little this drains all the power. Clear cmos 2-3 than return to
1-2 position.
Than plug the power back in and turn it back on, than try the computer again.

Mid 2006 iMac Boot Problem (Since latest firmware update)

I have a Mid 2006 17" iMac. Ever since the latest firmware update in early December, about every other startup I've been having boot problems. After the white screen with the Apple Logo and the spinning wheel it goes to a blue screen like normal, but instead of the 'Loading Mac OS X' white window popping up it stays blue and the spinning loading wheel starts. I've left it loading for quite a while before and nothing changes. I have to do a force shut off by holding the power button. and then I start it up and it will boot normally.
Any help would be appreciated.
Thanks!

Actually, I think it'san early 2006.

Lion, Boot Camp and Windows 7 Issues

Couple of questions regarding Lion, Boot Camp and Windows 7... I never had issues with Snow Leopard and setting up Windows 7 on my iMac (expcept the dreaded black screen after restart, bu got that fixed)
Let me start off with my specs and then I will ask my questions:
iMac 27"
i7 Quad Core (1st gen)
16GB Ram
1TB HDD
OS X Lion (Fresh Install - Not Upgrade)
All updates for OS and iLife and other installed software:
Adobe Creative Suite CS5
MS Office 2011
Boot Camp 4.0
Window 7 Ultimate
Ok... here are my questions.
When I fixed my black screen issues after installing a fresh copy of Windows 7 - I had to install MacFUSE and Tuxera NTFS in order to delete the the stock ATI driver so the second rebot on the install of windows 7 would work and boot correctly. After rebotting into my mac side I now always get this message from Tuxera.
What does this mean? Now in the finder when looking at the computer drives.. It does not show the BOOTCAMP partition...
However, when I resart i can hold down the ALT key and get this menu:
I know this might seem strange to ask, but why are the Macintosh HD and the Recovery HD text smoothed and the Windows text not? Being a design I see the difference and it makes me wonder why this is. (It is almost like the BSOD icon apple used forwhen connecting with shared PCs)... Anyways, I can boot into windows when clicking this drive.
After getting to windows 7 it will not let me run updated. The OS is activated and I have even installed SP1 manually, but it always tells me that the Update service is not running. When in fact it is. I have checked it and it is set to start automatically. I have reset and shutdown my computer more than 10 times... I can't figure out what the issues are.
Overview:
Why do I get the Tuxera NTFS error?
Why can I see the boot camp partion when manually selecting it form startup, but it does not show in OS X
I can't get Windows to update? Any ideas?
Thanks for any help you can provide.

These various utilities like Tuxera are incompatible with Lion. Partly because MacFuse is incompatible. You need to remove them completely.
As for the Windows partition you might consider using Boot Camp Assistant to remove it. Then make a new partition and install Windows. Remember to use the Windows formatter to format the Windows partition NTFS.

1st series iMac G5: Booting problems, kernel panics, waking from sleep...

Specifications of the iMac described: 1.8 Ghz, 1GB, 80GB, 64 Mb Nvidia VRAM, Airport, 10.5.5
Back in August 2004 my dad bought us kids an iMac G5 for ‘family use’. It had a fresh install of 10.3.5 on it and compared to the (1999) iMac G3 it replaced it was amazingly fast.
The iMac never showed any signs of probable issues, until we decided to upgrade to Leopard in January 2008. Initially, this upgrade was only meant to be able to sync with the latest iPod nano (who demanded a newer version of iTunes).
After the installation the first thing I noticed was a high CPU usage, the machine seemed slower than ever and that with 1 Gb of RAM (the minimum sys. req. for Leopard are 512 Mb of RAM). Anyway, then the real thing started, it wouldn’t turn on anymore. We brought it to an Authorized Apple Reseller, the Tech department said the Logic board had failed. The costs of the fix weren’t the worth the computer anymore, so...end of story. The iMac was indeed one of the bad series, although it hadn’t any swollen capacitors.
My dad already made up his mind and bought himself a Macbook. He then told me that if I was able to get the broken iMac fixed, I could keep it. And so, I bought an ‘as-is’ logic board on Ebay. Last weekend I installed it, and it actually seemed to work! Yet, the problems are during the startup: the first thing I see is a screen full with horizontal lines flickering all the time, like an old TV with bad signal. Mostly it won’t boot and I get the message to restart the computer (kernel panic, I got dozens of logs already!). Sometimes it got stuck during booting (grey apple screen with gear in the middle) making the fans go crazy (after a while) and sounding what others describe as a ‘jetliner taking off’ sound. Sometimes the screen remains black. Generally it takes me 5 to 10 minutes to start up properly. Maybe it’s just me but it seems like when the computer has warmed up a little (by turning on and off on and on) starting up gets smoother. I mean the startup screen suffers from less horizontal flickering lines.
During the use of Leopard, I again get high CPU usage, especially when I use multiple programs at the same time, or when starting multiple programs. My iStat Pro said once that the fans were running at 4700 rpm and the heat of the CPU was about 70 Celsius. If I really want to **** my iMac off I should play a racing game. That just totally freaks him out! These problems could probably be solved by adding more RAM. Right?
The iMac also has a sleep problem. Sometimes after lets say an hour or so, you can’t get it out of sleep mode (by manipulating keyboard and/or mouse, the sleep light stops, but the screen stays off --> only solution is to restart). What happened to me once was that it slept so long that it just got into a deep sleep by turning itself off completely!
Here’s a list of what I tried so far:
- Disk Utility: Resetting the permissions, no problems were found.
- Resetting the SMU, both on the logic board itself as by pressing the power button 5 - 8 seconds, no improvements.
- Resetting the PRAM, no improvements.
- Did the Hardware test of the original install CD, nothing was found, all good.
- Did Archive and Instal, this actually messed my system entirely, cause it wouldn't boot at all and when starting up from the Leopard installation DVD it wouldn't recognize the Macintosh HD.
- Did Archive and Instal with the original disks, this disk did recognize Macintosh HD and so I installed the original system, 10.3. Booting problems and those flickering lines are still there though.
Next phase will be erase and install, but first I want to know what you guys think about all this.
Oh eh, One more thing; The guys at Applecare (phone support) told me that the replaced logic board was also out of warranty and so they couldn’t help me. But as the man on the phone was kind, he told me to go look for a special ‘driver’ on the net. He said that the driver should be able to resolve some of the issues described. He said that I had to give in the name of the LB on google and look for results. Is this bogus? Because I haven’t found anything useful on google so far. What’s the name (rather than a number) of the LB in the first place?
I hope you guys can give me some answers. I'm kinda desperate. But I still feel there's hope...

The symptoms of a flakey power supply are sleep problems and you have done all the right things as far as resetting the SMU and PRAM. Your CPU usage can be tracked by going to Utilities>Activity Monitor - look and see what is hogging the memory. The flickering lines could also be an optical system going south.
The other thing you can do is run DiskWarrior or TechToolPro to see if you have corrupted directories. Preferential Treatment will let you check for corrupted preferences.

MSI P45 Neo-f with intermittent boot problems

Current system:
*CPU: Intel core2duo 4300 1,80GHz
Mobo: MSI P45 Neo-F LGA775
*Memory: 1 Kingston 1GB PC2-5300 667MHz DDR2 and 1 Dane-Elec 1GB PC2-5300 667MHz DDR2
Videocard: Club3D Nvidia 8800GT 512MB GDDR3
*Hard drive: 120GB IBM deskstar 7200rpm Ultra-ATA/100 (yes I realize it is known as the deathstar, but it hasn't failed so far, I do back-up because I'm paranoid
PSU: Real Silent Nexus NX-5000 500 watt
*Soundcard: Soundblaster Audigy
OS: Windows XP home, service pack 2
*Lite-on IT dvd-rom drive
*floppy disk drive
I also have 3 case fans spinning away in a marginally large Chieftec Dragon tower.
The parts I marked with an asterisk (*) are parts that I removed from my old rig and re-used.
I'll try to give a clear rundown of my problem and the steps I've taken so far.
3 days ago I acquired the P45 Neo and installed it into my system, together with the 8800GT videocard. I was still using my old PSU, a Chieftec 360watt. This PSU served me well for 7 years, but it was starting to build up noise while trying to keep up games on my old rig.
I had some trouble getting the system to boot, I tried changing some of the 4 pins wires going to the hard drive and the dvd drive. I don't know if it was luck or if I managed to divide the load properly for the system to boot. But I succeeded into booting up, got into the bios and eventually installed WinXP.
As soon as it was time to install the videocard drivers, it stopped responding. I assumed it was a power issue, since I could only install the 20pin and 4pin cpu, but my Chieftec PSU didn't have a 24pin plug to the mobo - and it needed replacing anyway! So I bought a new 500watt PSU that had all the required plugs and more wattage.
I installed the new PSU, checked every connection and pressed the power button. 'Lo and behold, the computer starts up. I install the videocard drivers and it proceeds with no problems. I try to install the soundcard, but the cd says I don't have one installed. I fix that by going to the System list and install the drivers from there. I install a firewall. By then I have successfully rebooted the computer 3 or 4 times. I decide all is well and turn off the computer. But I realize I wanted to check up something on the internet.
I press the powerbutton. The PC power light go up for just a fraction of a second. I can see the blue LED of one of the case fans switching on just as briefly - then it goes out. The computer keeps trying to turn itself on. It looks like it's hickupping to try and boot!
I turn off the PSU power on the back-side because the computer keeps trying and wait for a bit. After 10 minutes, it still doesn't work. I leave the computer for a bit and return an hour later. The computer then starts up with no problems. I turn it off after a few hours, do a reset, start it up, no problems. But then the next day it happens again.
It's pretty tough figuring out what the problem is because it looks..almost random. I considered it could be a heat issue, but sometimes it *does* start up just after it's been turned down. Checking the bios shows no strange temperature shifts.
Hope anyone can help me, because I do not want to go back to my old Asrock mobo

While powered down I cleared the cmos data, removed the Dane Elec DDR2 module and set the bios to optimized defaults. Computer restarted to WinXP with no problems (it has been off the whole night). I shut down WinXP, wait a few moments and then turn the computer back on. Alas, it won't start and starts hick-upping. I turn power off at the PSU again, so it stops.
Now I try switching out the Kingston module instead. By now the computer has been off for 10 min (while I write this entry on laptop). I press the power button on the PSU and then the power button on the front. There is a short pause, lasting a second. The computer turns on, longer now, but it only lasts 2 whole seconds before it turns off again and goes on again (I believe now you can call it powercycling). It repeats this process until I shut off the PSU.
I check to see if I have installed it properly and try again but it starts powercycling again.
15 min pass, I put the Kingston module back in, press the power button and voila, this time it does start. WinXP shows up, no problems. I leave it on for a bit and then shut down. And when I press the power button again - the feeling of dread returns, when it starts hickupping again.
I'm going to see if I can install one of the memory modules from my housemate. Then hopefully tommorrow, I'm going to try if I can test a different PSU, since I see someone else on the forum - who recently posted, has the exact same power supply and also has boot problems, coincidence... or not ^^;.

I have an early 2008 Mac Pro, which has re-booting problems. Also what does the spinning beach-ball indicate?

Hi, I have an early 2008 Mac Pro which has re-booting problems.
Processor speed is: 2.8
Memory: 2GB 800 MHz DDR2 FB-DIMM
2 x 28GHz Quad Core Intel Xeon
I am running OSX Yosemite Version 10.10
My Mac Pro keeps re-booting. Last year I had to replace my graphics card. My original card was the ATI Radeon HD 2600 XT 255MB, and that is what I have now. At this precise moment my Mac Pro is running perfectly, except that it is slow and the spinning beach-ball keeps appearing. I have managed to do some work with the disk utilities, verifying, cleaning and partitioning. Some errors were found and when it was cleaned this seemed to help my Mac Pro to function properly. Although I am able to use my Mac Pro now, from day to day I still experience re-boot problems. Also quite unexpectedly my mac dictionary has an error, it closed itself down and will not open at all, I had the message to say that a report will be sent to Apple.
I have tried starting my computer with an external hard drive fitted via a USB cable, I use for back-ups. This worked and I was able to wipe my hard drive clear and replace all info from the back up I had done only a few days ago.
This worked for a few days and then the same problem started again.
I am beginning to wonder if I need to buy a new hard drive.
If there is anyone who has some answers to help me solve my problem, I would be most grateful.
Robert

Windows 8.1 pro boot problems

I upgraded my OS on a hp pavilion g6-1d73us from windows 7 home premium to windows 8.1 pro and ever since I have had boot problems. I took all the software off since I thought that might be the problem but the boot problems persist. The computer's self diagnosis helps but I still have problems. Is my laptop incompatible with windows 8.1? Windows 8.1 was a download and I still have recovery disks for windows 7. I originally thought the problem was incompatible software but now I am not sure.

Hi @hifive11 ,
Thank you for visiting the HP Support Forums and Welcome. I am glad you have recovery disks for windows 7, smart thinking. I have looked into your issue about your HP Pavilion g6-1d73us Notebook and having issues with the Windows upgrade to 8.1. Here is a link to the drivers page for your product. I do notice there are drivers for Windows 8.The Updates you need for the system are the Chipset. These are located on the driver page link above.
One of the things that can cause an issue is things connected USB. The computer can not load the drivers so it causes an issue. Once the machine is up to date then return the USB devices.
Then I recommended to restore the BIOS to factory defaults.Here is a link to restore the BIOS.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
Please note remove any and all USB devices. Disconnect all non-essential devices.
Hope this helps.
Thanks.
