I got it sorted, it was probably my fault not understanding the options properly. The actual install can only be started by that last option that says eider: remove windows 7 or later version OR install windows 7 or later version So if you already have a Windows partition created you will see remove windows 7 or later version, you need to remove it and ...

The answer appears to be a qualified yes. A post in the Apple discussions link says that there would be firmware logs (note Target Disk Mode is activated in the EFI before the OS loads) in /var/log/system.log: kernel: hfs: mounted YourDiskName on device diskXsX Note this looks like a kernel log to me, so I'm not sure I believe it, but it may well be the ...

Most of what you are looking for is recorded, the issue is finding the right log. This question (unix.stackexchange.com) is similar to yours and has a couple of good answers.

Ok, the solution was ridiculous... Really. My MacMini got any signals from infrared like maybe only the light or any remote control or whatever in room. It works normal when I put anything on the infrared-receiver on my MacMini. The signal was like an option-keypress (menu on remote control) Hope that helps people in future

I'm reloading the OS on a MacBookPro3,1, and was having the same issue. I inserted a cable into the FireWire 400 port and wiggled the cable (gently) and the problem went away, so it seems like it was just some junk built up on the connector...

If none of the disk utility and external boot options are working for you try this: Run diskutil list to get the device address Use sudo diskutil unmountDisk force /dev/disk2 to force unmounting (replace disk2 with the right name from the first step!)

If you can't boot to a grey screen after resetting the SMC and then connecting a working charger for 15 minutes, you have a hardware issue. The steps a hardware technician would perform are as follows: Disconnect everything you can from the Mac Try a power on when connected to power. (Observing whether the charge LED goes green or orange is an important ...

It could be something as simple as the MagSafe DC board or it could be the whole logic board. See below: Normally, I wouldn't recommend that a user change out this part as Apple goes out of their way to make a complex assembly, but since you have an oscilloscope on your workbench.... The part is relatively inexpensive as compared to a logic board and I ...

Nothing stands out in your log, there are two options... You can download the 10.10.4 combo update on to another Mac, and using target disk mode on your broken Mac, you can reinstall the update again, ensuring to click Your broken Mac in the installer window, not the local machine... If you do this do a backup first. Or you can simply do an Archive and ...

I have a 13" MacBook Pro (late 2011) running OSX 10.9.5. To resolve this issue go to system preferences > Start Up Disk > select Macintosh HD

I've been struggling with the same problem but this works for me: convert the .dmg image with power iso to iso put the iso on a usb stick (drag it into your mac hard drive and mount it) format your usb stick with the disk utility tool. (Make sure the usb is partitioned as mac bootable then use use the image recovery and put your mounted OS X iso into the ...

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 ...
