It can't find the kernel files. When you turn on your Mac make sure you pressing and holding the the "Option" key then selecting the USB flash? If you are still having difficulty, then the creation of the USB flash disk didn't go so well. I am assuming that you have a good DMG image of the Snow Leopard DVD. You can't just "copy" or restore the image to ...

I do this on my MacBook using Bootcamp which comes with the Mac OS. It allows me to partition off my hard drive into 2 and by holding down the Alt key when the Mac boots, it asks which OS I'd like to start. I can only use one at a time though. Recently I prefer to just run a VM of Windows from inside my Mac OS using VirtualBox.

I figured it out, my hd was getting mounted under Volumes and had to be removed with diskutil unmount /Volumes/Macintosh\ HD Don't know why unmountdisk wasn't fixing this but whatever

Quite simply, you purchase a license for OS X by buying a Mac. It is licensed only for Apple hardware. There is no other way to legitimately run it, either natively or in VM. Running it on any other hardware would be against Apple's EULA & would also be off-topic for StackExchange.

The boot problem seemed to have been related to a disk error on the hard disk of the mac. I ran the disk utility and it detected a problem with the macbook's HDD (something with doubled file links), which it then repaired. The computer was still slow and unresponsive after the disk repair. After that the boot from the USB worked fine, and I was able to clean ...

This one is already answered in the other discussion forum: Open SystemPreferences->StartupDisk and choose the SnowLeopard Disk, then restart. Lex

An installed OS X can be specific to older models. People that administer Macs professionally call this situation "forked" and no one likes to be "forked" by surprise. Boot the new Mac to the setup assistant (or if you have made an account there already consider making a new test user account and backing up everything on the new mac that you need to save). ...

I have answered a similar question here on stackexchange and you can do some diagnostics with Ultimate Boot CD. First thing...can you boot into "single user mode?" 1) Press the power button to start the computer. 2) Immediately press and hold the Command-S If you are presented with a black screen and the system didn't crash then we are off to a good ...

Follow these steps to start up into safe mode. Start or restart your Mac. Immediately after you hear the startup sound, press and hold the Shift key. Release the Shift key when you see the Apple logo appear on the screen. After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac ...

This was apparently some known issue because when I took the computer to be fixed, they simply replaced the motherboard for free.

Well I've finally found an answer: just use a Windows 8 install CD ROM with the standard 'install Windows 7 or later option' selected. Do not install Windows 8.1. It seems the problem is with the latter messing around Boot Camp normal procedures rendering audio and some other components unusable. Where my MBP 13″ mid 2012 wouldn't complete my installation ...

I upgraded several Macbooks with Samsung SSDs. But they were EVO 840. Here is what I noted for myself: SDD had to be plugged instead of the original HDD. Plugging in instead of DVD gives issues. The connector is very hard to plug and unplug to Samsung SSDs. It is much easier with Apple HDD. So you have to press firm to plug in the SSD. To unplug, gently ...

Just reinstall rEFInd http://sourceforge.net/projects/refind/ This way this runs before Grub which seems to not work very well to boot the Mac OS side of the system

I've just recovered a Macbook (OS X 10.5.2, Leopard) which failed to boot because it got eternally stuck at a grey screen with an Apple logo and a spinning wheel. The culprit was a corrupted configuration file (/etc/authorization), and below I'll describe how I found and resolved the issue. First, I checked whether the hardware was okay, by rebooting and ...

Basically you have to delete the linux partitions (disk0s4 and disk0s5) and then expand your CoreStorage volume (Macintosh HD) to the full size. Boot to Internet Recovery Mode by pressing altcmdR while booting Open Terminal in the menubar -> Utilities enter diskutil list and diskutil cs list to get the partition and the CoreStorage listing. Now unmount all ...

Update 2 Based on the current state of your MBR and GUID partition tables, I recommend the following steps to finish fixing your computer. I do not think it is necessary to boot to Internet Recovery Mode before entering these commands. Make a Time Machine or other form of backup. (Just in case.) Execute my Update 1 on /dev/disk0. Upon completion, the ...

Disk Utility repair functions are (from what I have heard) just a front end to FSCK, so that will likely give you the same results. You could try another disk repair utility (diskWarrior, techtool, etc...), or if you have a recent backup I would be tempted to wipe the drive and start over. If you have another Mac you could put that Mac into target disk ...

Try the following: Open the "Keyboard" preferences pane In the "Keyboard" tab, turn on the "Show Keyboard and Character Viewers in menu bar" checkbox Go to the new menu (it looks like a box with a command key clover-leaf in it) and choose "Show Keyboard Viewer" You'll now see a window shaped like your keyboard, with every key shown, and each pressed key ...

It sounds like there is a problem with the USB installer. To confirm this, restart holding Option + R to return to Disk Utility, and verify you formatted the drive as "Mac OS X Extended (Journaled). If you have a working bootable usb, holding the "option" key should show you the Startup Manager menu: https://support.apple.com/en-us/HT204417 Here are a ...

I brought the macbook to an Apple dealer to get it checked. They repaired it under the "MacBook Pro Repair Extension Program for Video Issues", and I did not have to pay for it. This means the culprit was the video card.

It seems that you may be trying to fsck the wrong partition. You can use duskutil to find which disk is your boot disk diskutil list You're looking for something named usually "Macintosh HD" or "Yosemite". Try the fsck on that, and if you're still getting the "Resource busy" error, try to unmount it, either in the Disk Utility in recovery, or by using ...

A couple of things to check: reset your NVRAM since the startup disk is stored there set the desired startup disk from OS X (or by blessing it manually from OS X) after the NVRAM clear use a third party boot manager - Boot Runner is about the best there is, but you have lots of options from free to open-source

Try this http://www.macworld.co.uk/news/mac/steps-take-when-your-mac-wont-start-3423817/ You could start with resetting the NVRAM. Just try a few things from the above URL—might help to resolve the issue. Reset the NVRAM, because why not? In the PowerPC days, we talked about resetting the PRAM. On modern Macs, the real term is resetting the NVRAM. ...

There is no software utility to check if a cable is defective. your symptoms are odd and could point to an issue with NVRAM that booting into the boot selector allows you to force EFI to pick a boot device manually. I would zap the PRAM (boot holding COMMAND, OPTION, P, R) and let it bong three times. Failing that try resetting the SMC (power off the Mac, ...

I don't know the precise technical reason, but unless your NVidia is specifically flashed for Mac it doesn't load the drivers until you reach the desktop. As you can see, this makes dealing with anything prior to that quite difficult. For boot camp the simplest workaround is to define the startup disk before rebooting. As you've noticed, keeping the ...
