Hi, and welcome to JustAnswer/Pearl! My name is XXXXX XXXXX I am excited to get started with you.So I can better assist you, I will need additional information. What displays on your screen when you are attempting to boot?
it veries... normal boot
normal boot> grey blank screen after apple logo and rolling circle
if i try recovey mode cmd+r i get a blue screen
safe mode is pretty much the same with grey blank screen at the end
Thanks for the additional info. When you receive a spinning gear, it could either be related to your hard drive or a corrupt operating system. What operating system are you running?
single user mode work ok... it thells me that my root drive is read-only
fsck -fy commads tells me that my files were modified
Are you able to boot into Safe mode?
and the second time it tells me that my drive appeares to be ok. then i reboot and grey screen.
nope, safe mode also takes me to grey screen
or sometimes blue
Do you at least get the progress bar at the bottom of the apple logo
Does it try to fill up?
at the verbose boot i see that the bootchache.plist is missing
yes it is
Safe mode takes a very long time to boot. Do you remember how long you waited after the progress bar filled up?
it does take longer and i thing it doesnt fill all the way..
iv just started a safemode boot
Ok, lets wait to see if it boots into Safemode. If not, next we will reset your Computers PRAM and then attempt to boot into the lion recovery partition again
ok, iv done it before... proggerss bar dissapeared
ok now lets wait for it to boot
now only gear and an apple
it can take 5-8 mins from the spinning gear
it stopped at a blue screen
Do you have a backup of your data?
Do you still have your snow leopard install disk?
yes, its in the drive
Ok, so here is what we may need to do. First I still would like you to try to boot into recovery mode again. Make sure you are holding both command and r keys immediately after your computer boots and continue to hold until you see the apple logo. If that fails, you can then boot from a snow leopard install. You will then need to erase the hard drive and re-install snowleopard (since you can not go back in operating systems) from snow leopard you will then need to upgrade to lion
ok, dont you want to reset the ram first?
Yes, that comes before booting into recovery mode.
.Shut down the computer.
2.Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3.Turn on the computer.
4.Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears. Let computer chime 4 times
5.Hold the keys down until the computer restarts and you hear the startup sound four time.s
6.Release the keys and immediately press and hold Command+ R until the apple logo appears
I will stand by while you try that
Ok now lets see if it will boot into the recovery partition
Ok. give it a few more minutes
with the blue screen on?
It normally can take 2 mins
depending on the condition of your drive, it may take longer
thought that the blue screen is a dead end. you are saying that there is a progress in the background...?
The blue screen is an indication that it is loading the contents that will be displayed. If you notice when you start your computer, a blue screen will flash before it loads your desktop items. Whenever there is a prolonged bluescreen, it may be having issues loading the operating system. It looks more like an OS issue and not a hardware issue
im not sure but i think that this blue screen is different than the login one. this look more like a pattern of thin black lines and thicker blue lines
Ohh that it very different from a blue screen which is what you mentioned earlier. When you see vertical lines, that is related to the logic board. Before we draw that conclusion indefinitely can you connect your drive that has a bootable snow leopard install
Shut down your computer and boot while holding the option key until you see hard drive images
i see the cd in the menu
Ok, click on the CD
now logo and gear
While we are waiting, does the lines on your screen look simular to this one?
not quite.. its only when the blue screen is on, never on generic UI image
now i got a solid grey/white screen, the gear and logo went away
By the way, when you saw the CD image, did you also see the Hard drive image?
my lines a much thinner and with small 1px black gapes
yes, two of them the normal one and the recovry one.
Ok. Good. Has snow leopard came up yet?
no, still blank screen.
Lets give a bit longer, if not. Boot into the recovery partition again this time booting holding down the option key. I will like you to leave it for 15 mins. This will determine if the issue is with your logic board. Whenever you have booting issues, it normally stems from the logic board
a logic board is the motherboard?
Apple uses Logic board terminology
deos my apple care covers this?
Yes it does
but it will only take two month... :/
Are you near one or will you need to mail it in?
an apple lab?
Yes an apple store.
there is one of an ressellers, i live in Israel and there is no apple store here. my mbp is from thailand
Ohh ok I see. So you will need to mail it in then. Lets wait 15 mins first. Can you Option boot again and then choose the recovery partition
does RAM upgreads harms the apple care?
No. That is considered a user installable part
The Ram and hard drive are the only parts you can touch without voiding the warranty. (unless you upgraded the hard drive and the hard drive failed, that will not cover the hard drive )
i hear the fans are working very hard during every blank screen
my HD is still the stock one...
Is you computer unusually warm at the bottom or anywhere
its usually between 60-91 deg. i do alot of rendering aswell
OK. Have you option booted into the recovery partition yet?
no, im still waiting at the blank screen.should i reboot?
holding opt down..
choosing recovery 10.8
Now let that sit for 15 mins
Ok now choose your language
Then in the Utilities screen choose disk utility
Choose macintosh HD and then choose verify disk
Just to make sure, I know it was performed in single user mode
By the way, there are no distorted images on your screen correct?
Great. So the culprit may have been a corrupt operating system. Under format at the bottom, what does it read?
Mac Os Extended (Journald)
verification complited with no errors
Ok that is the correct format. (not sure why you received a read only notifications)
Ok now we will need to re-install your operating system
If for some reason your issue persist, you will need to perform a clean install
will it erease my installed apps?
Re-installing your operating system does not erase any data
So all you applications and stuff will still be there
let go for it
Ok, go ahead and exit disk utility. You will now be at the utility screen again. Choose re-Install Mac OSX
Choose Mac HD as the destination and then just continue to hit continue until the install begins
This will take about 45 mins to complete. So leave our chat open and give me an update when the install is done
it estimates 3 hr. ....
Wow How fast is your internet
Ok so then yes it is going to take some time
it has all started from a sudden crush during rendering... would i every be able to diagnose what caused it? before we started i did a hardware test that completed with no errors. should i keep relying on this computer as my main and only working station? my trust is damaged . does these kind of malfunctions happen often? this is my first mac ever and im using it for about a year and a half. how can i be more secure?
sharing my thoughts...
there were two operetions that might have caused it maybe...1. using "clean my mac" to scan and remove leftover components. 2. seting up time-maching backup on an old drive..???
I am not sure what exactly happend that caused your issue to occur. I can say that computers are not 100% and can have issues relating to either the hardware or software. With that being said, it is normal to experience issues related to yours where you will need to re-install your operating system (which is why the recovery partition exist). The first things you have mentioned can defiantly put you in the same issue if completed again. Some times "Clean my mac" deletes junk files that you do not need and some times it deletes system files that you do need for your computer to function correctly. Setting up time machine machine from an old drive is safe as long as the drive is in working condition
Time machine just backs up to the drive, it does not delete anything or transfer anything to your computer
How is it going?
3 min left
installing time remaining 34 min
So it rebooted?
It is suppose to reboot after the install. Did it reboot and then continue the installation process?
yes. it rebooted and logged in to the installation screen. its different than the download screen
OK so approx.. 30 more mins
Did it boot to your desktop?
there is 1 px left in the bar
Ha ha. Ok
If it is successful, it should boot to your desktop
Yay! That is great new. There are few more steps
what are they?
Since you had to re-install your OS, it puts the generic version on. This means some of your applications will not work properly until you perform your software updates. Click on the apple logo in the upper left corner and choose software updates. You will need to repeat those steps until you have no more updates left
its trying to open all my previosly opened apps
Thats is a feature in Lion. It opens all your applications and documents that were open when your computer shut down
should i force quit them?
Yes you can if you wish
If you do not need them
You are pretty much set from here. All that is left is to run all your updates over and over until it says "your software is up to date"
dont need web browser and mail at the moment :)
You may need to close all your apps anyway so your updates can run
Would you like me to stick around while you are running your updates?
I dont think so... :)
Ok you are all set. Thank you so much for your patience and I am glad you are up and running again
