Oct 13, 2014 While OS X Yosemite is a free download and arrives as a simple to use installer from the Mac App Store, you’ll want to prepare your Mac before jumping into the update to OS X 10.10. That’s what we’re going to cover here with five simple tips to get everything squared away, updated, and ready to go. 1: Should you update your Mac to Yosemite? Join the conversation.

I am trying to make a bootable Flash Drive with macOS High Sierra, but there is two issues that it is happening and are the nexts. The computer where I wish to install it supposedly is an unsupported machine (But I’ve have found on internet, that even this it could be installed, by the way). Jan 20, 2013 ISO image mounting problems under Windows 8 Pro Whenever I try to mount ISO with the inbuilt mounting of Windows 8 Pro it returns 'Couldn't mount file' 'Sorry there was a problem mounting the file' or 'The disc image file is corrupted'.

There are numerous ways to create bootable USB installer for hackintosh, most of them are Chameleon based and Unibeast is just one of them. The installation process is quite simple if you bought your copy from App store. Download Unibeast and just follow tonymacx86 instructions and you are good to go. But you should consider that tonymacx86 is not an open source and therefore is not in OSx86 spirit. Also apparently he stole the code from qoopz , nawcom , AnV and few others that made the legacy kernel. Here is one great explanation why you should not use tonymacx86, and here is another.

But there is another way to install it and even more, it supports raw installESD.dmg instalation, it’s called myHack, it’s Chameleon based USB Instaler + after install utility. MyHack functionality is more less the same as Unibeast + Multibeast, just simplier and better…

When installing Mac OS X, it would be a good idea to use one extra hard disk drive for the installation, to preserve your old operating system, just in case something goes wrong.

You will need USB stick, minimum 8GB, all the data will be erased, so back it up if needed and format back after finish installation.

Also working OS X SL 10.6.8 or Lion is needed to make a bootable Mountain Lion USB. (if u don’t already have a working OS X and using Windows, you can download, burn and temporary install iatkos L1 ISO image (search torrents) and install it like shown on this tutorial (drivers selection depends on your hardware).

Second option, if you are using Windows is to install Snow Leopard or Lion on a virtual machine (Virtual Box), and run Unibeast on there instead. Virtualbox Extension Pack will be also needed to view USB drives from vm. This method will probably not work if your computer uses an Ivy Bridge processor.

With working OS X SL or Lion you can buy and download Mountain Lion from the App Store. If you’ve already bought it you can navigate to the Purchased tab and grab it from here. Once it’s downloaded the Installer will pop up but instead of running it just close it.

Use myHack to create your bootable USB installer

I ran into an interesting macOS error while working with a customer a couple of weeks ago. I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself.

The error was as the screenshot above shows; trying to open a dmg (disk image), macOS showed the error 'no mountable file systems'. If you see the 'no mountable file systems error' while opening a dmg, here's what you should try:

In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. (There's an example of that in my screenshot below.)
Reboot your Mac if you haven't already tried that. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot.
Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:
- Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.
- Type hdiutil attach -verbose into the terminal. Add a space at the end, but don't press enter yet.
- Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.
- Press enter.
macOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to Apple_APFS or error 112, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.
Here's an example of the end of hdiutil attach -verbose output that shows an APFS error due to an older version of macOS:
Think about if you have any kind of security policies on this machine to prevent writing to external drives (thumb drives, optical drives, etc). I haven't seen this one in action, but I read about this being a possibility while researching the issue.
Another suggestion added by a reader (thank you, Markus!) is that filesystem errors on your main Mac drive could be the cause of the disk image mounting errors. Here are instructions from Apple for scanning and repairing errors using Disk Utility. Note that in order to scan and repair errors on your main Macintosh HD drive, you'll need to reboot your Mac into recovery mode. You'll want to choose Disk Utility in the utilities listed in the recovery mode menu.
A new discovery from a reader (thank you, Colby!) is that APFS DMGs won't mount if you're booted in macOS booted in Safe Mode. (Who knew!?!) If you're not sure if you're in safe mode, select the Apple menu  > About This Mac > System Report button, then select the 'Software' heading from the left column. To exit safe mode, restart your Mac, without holding Shift during startup. Or, if you previously set your Mac to always boot into safe mode using nvram, turn off safe mode and have your Mac boot normally on the terminal:
- Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.
- Type/paste sudo nvram boot-args=' and press enter.
- Restart your Mac.
