I am not really sure why you would want to install Windows 8.1 without BootCamp. The USB stick needs to be a little bigger than the .iso file you are going to be burning. It doesn't matter if there is any data on it, this will totally erase the whole thing. Steps To Achieve Victory Download the ISO you want to use Open Terminal (in /Applications/Utilities)...

Background and explanations Please read all of this post at least once from start to finish before taking any action. All MacBook Pros from 2011 have a serious design defect.

I’m going to jump out on a limb here and make the assumption that you’re probably a Chrome user and before you went away you updated Chrome. If so, you're probably the victim of a Chrome updater bug and your issues are not related to your Apple hardware nor a bug with macOS. NOTE: If you're running Mac OS X El Capitan or later and have not disabled SIP, ...

No, your Mac is not possessed. And Yes, it’s trying to tell you something! A looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware. In other words, the Snow Leopard disc you’re trying to boot from contains a version of Snow ...

You might try resetting the pram on your mac. I understand that startup disk settings are stored there. If the disk is bootable on other Macs, it stands to reason that it should boot on this one. You can reset the pram by doing the following: Shut down the Mac. Locate the following four keys: option, command, p and r. You'll need them in the next step. ...

Before you're able to create a bootable OS X installer, you'll need to do the following first: Download the OS X Installer app from the Mac App Store.

You can then use the createinstallmedia tool to ...

Bootcamp can create a USB for PC. Just only check the "Create a Windows 7 or later version install disk" checkbox. A similar question from How to create a Windows 7 installation USB from OS X? shows that Bootcamp has the "ability to create install USBs" for Windows.

The command sudo launchctl unload -w /System/Library/LaunchDaemons/ will force-disable all launch daemons in /System/Library/LaunchDaemons/ and add respective entries in a disabled.plist. The command – entered accidentally – doesn't affect the "unforced" load state of a system daemon but overrides any existing state (loaded/unloaded). Removing the disabled....

It cannot be done in hardware Mac OS 10.0 through 10.3 only run on PowerPC machines. 10.4 and 10.5 could run on both (10.4 had separate versions for the two platforms, but 10.5 used a unified install). 10.6 and later can only run on Intel CPUs. Thus, there is no computer in existence that can run both 10.3 and 10.6. Also, 10.7 only supports 64-bit Intel ...

Your friend has no idea what he's talking about. You don't even need to use a Linux disc - you can use single user mode or a Mac OS X install disc to copy things or make changes to the filesystem. To prevent someone from booting into single user mode or from an unauthorized disc or external drive, your friend can set a firmware password. However, this, too, ...

You can try this but please make sure you backup first: Boot to single-user mode, hold down the command (i.e. cloverleaf or Apple) and "s" keys as the system begins to boot.

You can try to force fsck_hfs to rebuild the catalog by running fsck_hfs -Rc -d /dev/disk0s2 or (if you want to avoid having to answer the prompts) fsck_hfs -y -Rc -d /dev/disk0s2 Of course this will only fix logical damages and keep failing if the disk itself is damaged.

This is an older post, but I came across it today and figured I'd share what I found. The 'bless' command seems to make this work. First make sure the disk is mounted, find out which folder it is mounted to, and: sudo bless --folder <mount_path> -label <desired_label> For example: sudo bless --folder "/Volumes/Mac OS X Lion Install ESD" -...

The best you can do is set a firmware password in hopes that someone won't change the boot options stored in NVRAM or let the keyboard select an alternate software to boot and bypass your administrative passwords.

I was having the same issue, this is how I fixed it. As we are not able to get to Single User Recovery Mode by using the key sequence, Command + R + S at startup to run csrutil disable, it is not taking you to Single User Mode. Start by booting the computer in standard Single User Mode using Command + S. Once you are at the command-line, run the following ...
