MacBook Pro 15" 2.5 not booting up

A friend has a 2.5 GHZ 15" MacBook Pro and it's not booting, it appears the Apple logo and then the spinning wheel.
What can I tell him to do since he's not in the same city I live and that machine doesn't come with a dvd installer.
Thanks in advance

IF this is the only point of comparison (2.5GHz vs 2.8GHz on the current 15" MBP) you will probably never notice a difference between the two ... unless you are into hardcore video editing, Photoshop or gaming. Even then, a) you will be hard pressed to notice a difference without instruments to measure it and b) there are many other factors that can affect system performance way more than this trivial difference in CPU speed on a top-of-the-line Mac laptop.
If you have the $200 it would take to upgrade to the 2.8GHz CPU, I suggest a better investment would be to apply the money to upgrading to the 1TB Flash Storage or use it to get a good external hard drive to use for backup.

Good Morning,
I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
I also rebooted holding down the shift key and still no Snow Leopard
Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
thank you.

Have you restarted holding down the Opt key? That procedure should give you a gray screen with all of the partitions that exist. Then select the SL partition for boot. Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.

My macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty.

there was a recent software update that seemed to screw HDV up. Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
Worst case scenario, do as Shane suggests. But might I suggest you take a look at the user tips section of the forum. there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.

Late 2013 Macbook Pro Retina 15' will not boot an external disk from a Mid-2012 MAcbook Pro. What should I do?

In order to simplify moving all my files from the previous mid-2012 macbook pro 15' when moving to my new late-2013 macbook pro, i superdup-ed the full hard-disk to an external ssd. Unfortunatelly the new mac resuses to boot from this external disk (i get the grey disk with a line over it). The external disk works just fine so if I boot the new mac from its internal SSD I can read/write the external disk without problems.
Old OS X is 10.9 as is the OS on the new mac.
What I need to do is to boot the new mac from the external ssd, use the same superduper to copy the external content onto the internal ssd.
How can I solve this issue?

Welcome to Apple Support Communities
If you made a backup of your files with SuperDuper, use Migration Assistant (in /Applications/Utilities) to transfer your files from the external drive > http://pondini.org/OSX/MigrateLion.html It will create a new user account with the transferred files, so you may want to merge both user accounts > https://discussions.apple.com/docs/DOC-5472
The Late 2013 MacBook Pro uses a special OS X Mavericks version which makes OS X compatible with it, and older OS X versions do not work with it. That's the reason why you cannot start up from the external drive created from the Mid 2012 MacBook Pro

Macbook pro (snow leopard) will not boot after software update

I helped my mom buy a Macbook Pro for herself for Christmas. Today, I connected it to her old eMac and used the migration assistant to transfer files over. It was unable to estimate migration time on the only user (after 45 minutes) so I didn't migrate the user. Then I tried to pair her macbook to her new bluetooth keyboard, but no magic happened, so I tried to use the bluetooth setup assistant, which crashed. So I ran a software update, hoping that this would fix whatever the bluetooth problem is. Despite having updated on the 23rd, there were 4 updates. None seemed applicable but I installed them anyway. Now the computer won't boot at all.
Software update said that I had to restart for the updates to take effect, so I restarted. The harddrive went whirrrrrr and the grey screen with the apple logo and the spinning circle displayed. Then the harddrive stopped going whirrrr and 10 minutes later, I started looking on the support site for what to do. I found this:
http://discussions.apple.com/thread.jspa?messageID=10564149&#10564149
Per the instructions in the last post, I fscked the drive (although -f, in accordance with the fsck help). This found no problems. The next suggestion was to boot from the OSX install disk. Only one problem-- there was a disk in the disk drive when the problem occurred and the disk eject button apparently only works while in the gui. I can't install from disk if I can't get the existing disk out of the drive.
So, any other ideas on what I can do to get this machine to boot?

Hi Jen:
Since it's new, you're entitled to 90 days of phone support (3 years if you buy AppleCare). It sounds to me like you may have some hardware issue(s) going on - you should not have the sorts of issues you're having with a new Mac. Apple will probably be much better and faster about getting you fixed than this board may be able to if that is the case.

Macbook pro running,lion will not boot

My mac book,pro running lion will not complete the start up/boot have tried single user boot, and command v any ideas

I had the same problem... I was downloading the latest update (whatever it was for, I forget at this point)...
I was really frustrated because I have never had to troubleshoot my MacBook Pro (early 2008 or whatever was before the black bevel/chicklet keyboard), plus I was running Lion, so I did not know how to do any recovery.
Cmd + R worked like a charm. Repaired my disk, repaired my permissions, then reinstalled (or restored) Lion... now my computer is actually running better than before!
The Disk Repair feature in Lion works magic!

Deleted files now Macbook pro 13 2011 does not boot up

Tried following some instructions to delete search.genieo an safari and deleted some files. Now my Macbook pro 13 does not boot up at all. All I see is the screen with small apple and the running circle below indicating it is thinking. any clues anyone. Thxs

Just for the record, in case someone with the same problem stumbles across this topic later, I'll repeat the advice I gave you on another topic:
You did not follow the instructions precisely, and now you have suffered the fate that the giant red text on that page warned you about.
At this point, you will need to try the recovery instructions posted at the end of that page.

My macbook pro Mod A1261 will not boot. It goes to the gray death screen

When I try to boot my macbook Pro it goes to the gray screen of death (to borrow a term fmor the PC world). It will not boot in safe mode. It did this before and I though I had gotten it fixed but I guess not. Any suggestions?
Bill

If you look to the right there are so many examples of the same symptoms - just read them, study them, and see if the solutions about 'Safe Mode' 'Recovery Mode' 'Disk Repair' can solve the issue. After that do report back

Macbook Pro mid 2009 will not boot unless SMC is reset (macbookpro5,5)

Hello!
I have a mid-2009 Macbook Pro (macbookpro5,5) and I've had this weird issue for like a month, and I ran out of ideas.
So my problem is: whenever I turn on my mbp (either on OS X or Windows 7) it will go to sleep (on OS X after it shows the login screen and on Windows when it's loading) and when it wakes up, *it goes to sleep again*!
I kinda panicked back then because I couldn't get to boot the machine for all what was worth, but then I tried resetting the SMC and voila! it booted; and I thought that was it, but no, it wasn't: *I have to reset the SMC everytime I turn on the mbp*, or else the same sleeping loop will happen again and again.
This happened after installing the first March Update that Apple released (which misteriously only addressed iTunes issues - supposedly) on OS X. I already tried looking for SMC or EFI updates (just in case) and I already have the current versions (just EFI, SMC updates were never released for this mbp) so now I have no clue on what to do...
And what really puzzles me is that I disabled sleep when closing the lid on Windows 7, and it worked fine, but after this issue, it just goes to sleep, even when I see the closing the lid option on "do nothing", it's just weird.
Does anybody had some sort of trouble like that?? or anyone has some hints that may help me??

Well, it seems that apple fixed this issue in the 10.6.7 update. I kinda wish there was a little more documentation about the patches released and what files they modify, since no update was released to the SMC, I have no idea why it had to modify it. Anyway, thanks for the help!

1 week old Macbook pro will start but not boot up

This new Mac book pro will start when powered up but does not boot at that point and remains black screen.

Please make a Genius Appointment and take it in for repair or replacement. It's under warranty.

Macbook Pro 15 Mid 09 not booting, Bad MLB :(

I have a macbook pro mid 09 15" that I was using for video editing and production, I take very good care of my computer and even travel with a portable surge guard when plugging it in.
One morning I pressed the power button and nothing happend, screen is blank, no boot sound but the front light was on and the battery was charging.
I took it to an apple dealer here in Jamaica immediately and they confirmed that the problem was the logic board.
My computer is out of warranty and I cannot afford to buy a new $2000 computer every two years, is there anything Apple can do to help me get this fixed cheaper than to buy a logic board or computer?
Is there any current logic board repair/replacement program that the apple stores offer?

Hi w,
There is (or used to be) something called a "flat rate" or "depot" repair. It was under $350 and Apple would fix basically anything that was wrong with your Mac, IF it qualified. You will need to contact Apple to find out if that repair is still available and to determine if your Mac qualifies. Good luck.

MacBook Pro 15" i7 will not boot

My brother just ordered and received the i7 2.66GHz model of the 15" MBP. He had the previous 2009 unibody MacBook Pro. Rather than migrate the older HD to the new one and re-enter his serial numbers for many of his 3rd party apps, he opted to pull the old HD (which is 7200 rpm and the new one is 5400 rpm) and just put in the new machine. When he did this, he gets the Apple log on boot and nothing else. Any reasons for this? I called my local Apple-authorized dealer (and support center) and they said there is no reason they can think of why this is happening.
Any help would be greatly appreciated.
Thanks

Thanks so much for taking the time to answer. I'll let him know there are no shortcuts on this one

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

Macbook Pro 10.6 will not boot

Last night I had a kernel panic. When the system tried restarting it stuck on the grey/blue screen with the Apple logo and spinning wheel. I have tried booting in safe mode: same screen. I have booted with my OSX install disk and run a disk repair, which said the volume was fine. I ran a permissions repair which had errors, but they were the ones that Apple says you can ignore. From here I could not swich to my MacHD drive for start up (bless problem?)I have run a hardware test with my OSX install disk and it says there are no problems with any hardware. I cannot reinstall OSX with disk onto my hardrive as it finds a problem. I cannot erase my harddrive because it now will not unmount. Hoping there is a fix to all of this?? I feel like I have done everything that I have found in the forums with others' related problems. If anyone has ideas, please help. I am checking this forum using my phone and an HP (yikes!)

Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

OS clean install interupted on 2011 Macbook Pro G4. Now computer not booting up

I have a Mac Book Pro G4 (Early 2011) I was in the middle of doing a Yosemite clean install and I I took the memory stick out before the OS finished because I couldn't cancel and I thought it was hung-up. Now it doesn't power up. I get the attached message!
After this message it just restarts, then message appears after 8 secs or so then restarts again... I have the Software Install and Restore disk. It came with two. I tried that but it doesn't automatically open anything. I also tried to open in Safe mode but I don't think it get far enough along to do that... Help!!!!

I had downloaded Yosemite onto my Imac, then followed the instructions to create bootable OS on memory stick, Did that then tried to load that on my Macbook. I then made the mistake of taking it out mid install i think. Now it does what I mentioned above. The computer has tried to reboot with the memory stick in so that doesn't work... ;(
