MacBook Pro :: Can't Boot My System After Erasing Log Files?
Dec 15, 2010
I was doing some cleanup on my macbook pro, deleting old log files and suddenly the system froze. I turned off and then on the laptop and to my surprise, the Mac partition doesn't show up on bootcamp menu, and I'm taken directly to Windows.I tried booting from the install disk and repairing the disk with Disk Utility, and although all my data seems to be all right (I can see all of it from Windows), and Disk Utility did not find any errors, when I reboot (while holding the option key) only Windows shows up.

is there a way to keep the menu bar open always, without altering system codes or erasing system folders? when anything is in full screen, it disappears and I want to see the clock.

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

I shut off my iMac the other day and now when it boots I get a start up bar that looks like on my iPhone when uploading new os. And then it gets half way and starts over. It seems that my hard drive has an issue. I tried booting from snow leopard DVD. But I can't remember how to install a new system folder without erasing the drive. I tried making a bootable DVD of tech tool pro on a friends windows machine but it doesn't seem to work.
Info:
iMac, Mac OS X (10.6.7), 4GB ram. 3.06Ghz Core 2 Duo

I couldn't find it on OS X. On windows I used to right click the CD/DVD and click erase, but I don't see a similar option on my Mac. Do I need any special application for this?

I am a complete n00b when it comes to OSX just to warn you lol. Im just wondering, if one did a dual boot of windows alongside OSX, is it possible to access those files on the windows partition from OSX and likewise, is it possible to access those files on the OSX partition from wndows? Also, will Time Capsule only back up files from OSX or from across the whole mac? Sorry if this is a stupid question, as I am looking into buying a macbook and was wondering if this is possible.

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

Files remain after "erasing" disk iMac 10.6.x. I'm trying to reinstall leopard and for some reason 2 folders and 2 files (totaling 90mb) were left on. I'm thinking this is just preprogrammed files for my HD but just want to make sure this is the case and not some lingering 'infected' files.

I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.
Current Setup:
13" macbook pro
Snow Leopard and Windows XP through Boot Camp

My early-2010 i7 MBP keeps freezing within minutes of boot. I just tried booting in safe mode, and it just froze for the 6th time in 24hrs (like the 4th in a row). I've never performed a time machine backup with this computer (I got it about a month ago), so a full restore would be an absolute last ditch option. Like I said, this keeps happening within a minute of boot. The screen is on, but everything completely locks up. The cursor can't be moved, keyboard doesn't do anything, etc. I have to keep forcing it to shut off w/ the power button.

I'm just not having luck with my last 3 MacBook Pros. My new 2.8ghz 15" now takes over 7 minutes to boot to the login screen. Before this happened, I recently copied 139 GB in sound libraries to my system drive. Before I went to work, I quickly closed the laptop and put in my bag. When I took it out of my bag several hours later, the unit was off and battery practically at full charge. When I started it shortly afterwards, it took forever to boot. It would sit there at the grey screen with the spinning circle, then get to the blue background (just before you get to the login screen) and wait there for a while. Most of the time I think you can hear the hard drive churning.
Once you log on, everything seems to be normal. I'm curious if perhaps that 139GB copy did something to the OS to slow it down. FYI it has 274/ 500 GB of free space left. Perhaps the hard drive didn't have a chance to park when I quickly put the laptop in my bag and I damaged it? To complicate matters, I have the MCE optibay installed with a 320 GB hard drive loaded in it. The only thing I can think of is to back up, and reload the OS. This should tell me if it's software or hardware related.

I have a macbook here that is stuck in a restart loop. It boots until it gets to the blue screen and flickers and goes back to a post screen and keeps retrying. It also displays a message that a crash log was written to file xxxxxxx.I can boot into single user mode and found the folder containing the crash log, how do I view that file in single user mode? If I can't read it in single user mode how can I read it, transfer it onto usb and view on my imac?

My dads MacBook Pro started acting weird first the screen would freeze up and the cursor could still move but there would be about an inch wide black line that would follow on top of the cursor wherever you moved it.
We thought it was a software problem so we booted it up off an external drive and it did the same thing after a few seconds of loading the finder, now it won't even boot, it loads the white screen with the apple, then it stops at the blue screen where it usually shows the loading of everything, once in a while it will get past that but it freezes with black lines over the cursor.
I've tried zapping the pram and i've held the power button down till it beeps i've also reset the pmu, so im out of ideas.

I have a macbook with OSX 10.5.7 and 4gb ram. Having fallen victim to the current scare tactics out on the web, I downloaded and installed PC Tools's iantivirus. All went well with install. About half way through the initial system scan, iantivirus hung up and locked my system. I had to do a hard power off with the power button. Now, my mac will not boot past the Apple logo. I don't even get the spinning wheel. I have booted to my install disk and ran disk utilities and everything checks out ok. I reset the pram and removed the battery and power supply and held the power button down for 10 or so seconds. Nothing. After several minutes, the system restarts and the cycle begins again. I cannot get into safe mode.

I have a 2.0ghz unibody macbook, and i installed windows xp on the boot camp partition, installed drivers, up until here everything was working fine.. i decided it would be a good idea to upgrade to bootcamp 2.1 and then suddenly the boot camp icon in my system tray went away,
and so did the nvidia panel and the sound no longer worked.. now im stuck and i have no sound. I tried reinstalling the drivers using the cd and it still doesnt work.. also when i remove my headphones there is a red light coming from the jack.. how do i get my sound back?

When I press the power button the system stays with the image of the apple, and the "thinking" timer in the screen, but it wont proceed to the main frame, it is just stuck there.

Sooooo I just got my brand shiny new CTO 4GB 13.3 MBA this morning at about 9:45 am yesterday in Illinois. I was sposed to go to bed because I am working nights at the moment but i stayed up for hours setting it up and playing with it (my first MAC) and so I finally get home after working a 12 hour night shift and open up my new MBA expecting instant on and....nothing. The damn thing will not turn on and I tried all the tricks of the trade (suggested by apple support page) and nothing. It was fully charged when I left it in the morning. Also, my magsafe charge light is green which means it is still fully charged right??? Man what a super disappointment. My first MAC and it freaking dies immediately. My Win 7 desktop at least started...good ole faithful (granted it took about 55 seconds...pff)
I'm so sad!

The other day my 1st gen MBP functioned without any probs, until it suddenly powered down. After I removed the question marks from my eyes, I offcourse tried to reboot it.
But it never makes it beyond the grey screen, sometimes untill the apple logo, sometimes not even that far.
Offcours I googled around first to gather some info before I decided to put this problem down on this board. I found this could be a HDD failure, but in those cases, with other people, it could be powered holding apple + s, and doing some checks that way.
Mine doesn't even come that far
I have a second hand 1st gen MBP with upgraded HDD and RAM, snow leopard, and coincidently since last week no more battery... so i may have powered down a completely unprepared mac by tripping over the wire, once or twice...

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?

Since a few days ago my Macbook Pro 13" from last June started to freeze randomly for atleast 30 seconds and then it would come back and most of the time freeze again after a while (in OSX only it seems, Windows 7 I did not have such problems, though I didn't use it often). Sometimes it occured frequently, other times it didn't and this morning I had the same thing again, I just held the power button and shut it down, did this two times in a short period of time and when trying to boot it for the second time all I get is a gray screen with no Apple logo or anything.
Searched the forums, tried the install DVD and C button to no avail, same thing with trying to reset the PRAM and NVRAM...Is the logic board broken or anything? I don't understand how this could happen...And if I do take my laptop to Apple, should I remove the Intel SSD drive I got in it right now and put in the stock?
