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... ;(

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.

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.

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.

Windows 7 install on late 2011 MacBook Pro without bootcamp (performance issues)

Hey guys I'm hoping I can get this issue resolved. I have purchased a late 2011 MacBook Pro (radeon 6750m 1gig). I installed a fresh copy of windows 7 without bootcamp. Having real issues with game performance like world of Warcraft. I have done this with an older unibody Mac and it ran great (for any non believer)... But now this time around I'm getting horrible fps in game. I'm thinking it may be driver related it buy I am having trouble finding the right drivers to see if that's then issue. Any help on this would be greatly appreciated.

That is completely false. There is no real need to leave OS X on the Mac if you don't want to, especially with Win 7 or 8. That may of been true with Windows XP but not anymore.
The problem with leaving OS X installed is then you are really limited with what you can do with the drive. You can only have one Windows partition and if you fool with it at all Windows will no longer boot. you can't even change the OS X partition otherwise Windows would boot
Windows 7 will install all by itself. No need for any Boot loaders or Hack Boot system. Pop the Win 7 DVD in the DVD drive and restart. Windows will be installed all by itself. But you do need the Apple support files.
In the end if you are going to run Windows on a computer by itself then you really should not buy a Mac. The hardware is the same and as to the OPs perceived better built quality I personally do not see it. And if you actually read some of the posts on this and other Mac forums you will see that perceived build quality is just a bunch of hype, in my opinion.
To the OP. You aren't missing anything.
If you had carefully read what I wrote, I merely said that doing the install on a blank drive wasn't a good idea. That's because it can create issues the OP is having. A Mac's hardware is no different than a comparable Windows machine, but the EFI/BIOS/Firmware is. Macs are in something of a no-man's land in this regard, as they have neither an old-school BIOS or modern UEFI of recent Windows-based notebooks. I'm willing to bet that the performance problems the OP is having relates to the fact that a straight EFI install on a modern MBP "enables" (for lack of a better word) automatic graphic switching. The capability manifests, but the functionality is not there. Enterprising individuals have been trying to get graphic switching in Windows to work as it does on the OS X side ever since MacBooks debuted with this abliity but with zero success.
Using Boot Camp bypasses this, as the discreet GPU is enabled full-time in Windows. Thus, you will realize proper performance.
As far as perceived build quality, Apple machines are at the high end of the consumer notebook spectrum. They're certainly better than most of the other machines you can pick up at your local Best Buy, but they fall short of business-class machines such as the Dell Latitude/Precision, HP ProBook/EliteBook, and Lenovo ThinkPad.

Since installing Mavericks on my MacBook Pro, I have many (not all) documents that cannot be opened in either Pages '09 or Pages 5. They show on my doc lists, but are greyed out so I can't try to change extensions or anything else. Some are PDFs.

Since installing Mavericks on my MacBook Pro, I have many documents, but not all, that cannot be opened in either Pages 5 or in Pages '09. The names show in my document lists, but are greyed out. They do not show any extensions, but I'm sure at seast some of them are PDFs. As I cannot open them, I am unable to try to experiment with any solutions - I am not tech savvy, but can sometimes fix things by trial and error. I have no issues with sharing documents as I have no other devices. I just want to be able to open my saved documents! Also, the documents I can open have to be persistently coaxed to open to a point that it is extremely aggravating. I am not so happy with this recent "upgrade." Any advice would be greatly appreciated.

You use Finder to find stuff. It is what you use to look at where your files are kept and to rename, move or trash them. If you double click on a file in Finder it finds the right software to open it for you.
To open particular files you use the right software for each type. Usually, but not always, the software that made the file.
Pages opens files ending in .pages. Also .txt, .rtf, and doc.
Pages 5 is the latest (but certainly not the greatest) version of Pages. It has trouble opening all sorts of files including the older Pages '09 files but it will still do it.
Unfortunately Apple has chosen for Pages 5 to also save its files as exactly the same file extension .pages despite it being a different format that can not be opened by the older Pages '09.
As we all know Apple is wise and great beyond belief and would not do something that on the face of it looks extraordinarily stupid and shortsighted. Therefore we know that it must be our fault and we are not holding the software right. Because we are bad users, we must be punished, by either having to use Pages 5 or jump through hoops to avoid using Pages 5.
If you have installed Pages 5 any .pages file (old or new) will be opened by Pages 5. If you then save the file, Pages 5 will change the file format. So don't open your files with Pages 5 and don't save them if you do.
To stop Pages 5 opening and resaving your old files, you need to drag it to the trash and empty it.
When it is no longer around to annoy you, you can go back to using Pages 09.

New hard drive, clean install of Lion, but MacBook Pro is still freezing

Hi everyone,
Even the folks at the Apple store don't seem to know what's going on with my MacBook Pro.
My hard drive crashed a few weeks ago. I bought a Western Digital Scorpio Blue and replaced it myself. The MacBook didn't seem to like it (lots of freezing, going really slow, etc) and so, after reading online that many MacBook Pro users did not like the WD Scoprio Blue, I returned it and bought a 320 GB Hitachi. Before replacing the WD drive with the Hitachi drive, I used SuperDuper! to make my external hard drive a clone of the WD hard drive. I replaced the WD with the Hitachi, booted from the external, and then restored all my stuff to the Hitachi. The computer still didn't work so well, so I did a zero-out erase and a clean install of Lion. I dragged my files over individually (only about 100 GB of word documents, music, and photos). For the first two days, everything worked perfectly. Then I started getting these error messages:
Word: Word cannot save or create this file. The disk may be full or write protected. Try one of the following. *Free more memory. *Make sure that the disk you want to save the file on is not full, write-protected, or damaged.
Chrome: Your profile could not be opened correctly. Some features may be unavailable. Please check that the profile exists and you have permission to read and write its contents.
Dragging files to trash: The operation can't be completed because an unexpected error occured (error code -50).
Fireforx: Close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time.
In addition, the computer kept freezing. I also had problems with Mail and iTunes. Disk verify, permission verify, S.M.A.R.T. utility all said that the hard drive was working fine though.
So, I brought the computer to Apple. They did a zero-out erase, reinstalled Lion, and did what they called a "software repair". They said it should work fine. I just got home from the store, booted up the computer, and it's barely working. All sorts of error messages, safari won't work, it keeps freezing, and I was only able to open disk utility once. I verified disk, and it came up with no problems. I verified disk permissions, and when I tried to repair disk permissions, it kept saying it was "unable" to.
I don't know what it could be. It's not the hard drive...I've run disk utility, S.M.A.R.T., and an app that checks the hardware associated with the drive. All of these programs say the hard drive is absolutely fine. I've also reset PRAM. Another thing worth noting is that I'm currently booting/working off of my external, and it works absolutely perfectly.
Any ideas? One of my friends suggested I go back to Snow Leopard, but I don't see what difference that would make. Please help! Anything would be very much appreciated! Thanks!!

The theory is that you have a weak bit in one of the modules, and sometimes (rarely) it flips over. The trick is to try and catch it.
If you move the modules, the weak bit will be at a different Address in memory. Different things will be loaded into the word with the weak bit, and the symptoms may be different.
It may not do anything at all. But it is so easy to try, it is worth a shot.
On a multi-module memory, you need to keep your wits about you when doing this, or you put them back the way they were originally. So you should pick a direction and always move them your "regular" direction.

How to clean install os x on macbook pro late 2013 using usb (offline) (without recovery direct download)

hi,
Im trying to clean install OS X from last month using inbuild recovery partition method. Due to slow internet connection Im unable to complete the installation. I tried many times using this intallation process but it failled to complete the installation. My internet connection is steady but due to "time out" the whole installation process is skiping. So Im not able to use my brand new macbook pro late 2013 from last month beginning. Please provide an alternative solution to install os x.

For several years now, Apple has acted as if everyone on the planet has high speed Internet access. That is obviously not the case for many people, and for them installing or reinstalling any OS X version since Lion has been a problem.
I can only suggest that you take your MacBook Pro to a location that has a faster, publicly accessible Internet connection and download it there. An Apple Store would be ideal, but if that is not an option, a public library may offer high speed Internet, as do many hotels, coffee shops, or similar locations where you may have to pay a small fee.
When the download completes, you can copy the Install OS X Mavericks icon to another folder or an external storage device such as a flash drive, where it will remain available to use again, as often as you wish. Do that before proceeding with the Mavericks upgrade, otherwise the installer will erase the file.
The installer icon resembles the following
(Launchpad)
The following will also appear in /Applications:
Copy that to another location, such as Documents, by holding an option key while you drag it there.
Of course, every time Apple releases an OS X update you will need to download another, rather large file.

Clean install of Lion on MacBook Pro

Hello - I have been using Lion for a while now, with no problems, but am now having permission problems with such actions as emptying trash, downloads, upgrading certain apps, using Dropbox, etc. I think it has something to do with my user settings, but have tried in as many ways to repair this, to no avail. I am backing up my files on a Time Capsule - and the only things I am really wanting to keep are my iTunes files and my iPhoto files. (I upgraded from Snow Leopard to Lion.)
My questions:
1. Once everything is backed up to TC, what is the best way for me to do a clean install of Lion?
2. How do I then go about reinstalling my apps/files (iTunes, iPhoto, movie files, documents, etc)?
Also, is there anything one needs to be aware of when installing Lion in regards to user name, administrator, etc?
Thanks in advance.

Late 2011 MacBook Pro; one USB port not recognising anything

Hi,
I've had my MacBook Pro since January 2012, so I believe it is the late 2011 13" model. I'm currently running OSX 10.9 although the problem I've been having has been going on around 3 or 4 months, I think I had OSX 10.7 installed when the problem started.
One of the USB ports on my Mac (the one on the left when looking at them face on) is not recognising my external hard drives, or recognising/charging my iPhone when plugged into the USB. The other USB slot works fine and recognises external hard drives, however when I insert the hard drive into the faulty USB input, although the hard drive lights up and starts whirring as if it is ready to start functioning, it does not appear under the 'Devices' tab of the Finder screen, but does appear and function when using the other port.
Similarly, when I plug my iPhone 5 into the faulty port it is not recognised/does not start charging, however if I leave it running and come back later I often have at least a level of increased battery life which suggests that it does intermittently charge from time to time, and again it functions normally when using the fully functional port.
I've tried the NVRAM reset as I have read in another post but to no avail. Is this likely to be a mechanical fault over a software problem, and if so what could be wrong with it?
Thanks for the help in advance.

thank you shootist, at least now I know the problem is as serious as I dreaded, but will not loose hope waiting for a miracle and the port works again

Installing New Hardrive into Macbook Pro 13" and can't boot

I have installed a new 500Gb 5400rpm drive into my macbook pro 13. Before I swapped the drives I used time machine to back-up onto my Lacie drive. Now the new drive is in. I turned on the computer, pressed the option button and nothing came up. I have now put my old HD into an enclosure and booted up from that drive. I copied my whole hd over to the new drive once it was formatted and tried to boot but this didn't work. I thought once I had the time machine back-up on a drive I would be able to press option when I turn on the computer and then that would workj. I don't have my OSX 10.6.8disk so am now just booting up off my old hd which is pointless. Can anyone help as I am losing my mind.

What happens when you install the original HDD in the MBP? If it does not boot , the connecting cable may be faulty.
Ciao.

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??
Message was edited by: piku9000

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!

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.
