Note for adding an SSD to a 2012 Mac mini

Oh well. May be someday. SSD is good.

This particular instance affects you only if:

  • You are upgrading a 2012 Mac mini.
  • That 2012 Mac mini shipped with Mac OS X 10.8.2
  • You are adding an SSD to this Mac mini as a second drive, alongside the existing Hard Drive using an OWC Data Doubler Kit.

If your installation involves all three factors, then you need to pay attention, as your installation will be affected. If one or more of these factors are not involved, then you don’t have to worry.

Info comes from here:

Firefox: setting prefs to stop altering copy

Try setting about:config and setting dom.event.clipboardevents.enabled to false. This works for sites which use methods to alter the text you copy to add crap (like famous classified advertisements website ss.lv)

How to Create an OS X Mavericks USB Installation Drive

1. Download OS X Mavericks from the Mac App Store, if you haven’t already. If it tries to start the installation, just close it.

2. Insert your USB drive (you’ll need one that’s 8GB or larger) and open Disk Utility.

3. Select your drive in the sidebar and go to the Erase tab. Format the drive as “Mac OS Extended (Journaled)” and name the drive “Untitled.” (Note: if you already have a drive or partition named “Untitled” connected to your computer, name it something else and change the corresponding variable in step 5’s terminal command, or you might experience data loss!).

4. Click the Erase button and wait for Disk Utility to finish.

Your 8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.

5. Close Disk Utility and open up a Terminal window. Copy and paste this command* into the Terminal:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

Press Enter. The process should take about 20 minutes, so don’t cancel it or eject your USB drive while it’s doing its thing.

You should see something like this:

Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files…
Copy complete.

6. When it’s done, you should get a message stating the process is finished. Now, you can restart your computer, hold the Option key to access the boot menu, and select your new USB drive. From there, you can launch disk utility, format your drive, and do a clean install of Mavericks.

You can then boot up from the USB by holding down the option key, then install the Mavericks from the USB.

Note that this will also install a recovery partition.

Direct Install of Windows 7 from Hard drive

How to Install Windows 7 directly from Hard drive

For example, you have a lapbook or desktop that you want to install Windows 7 onto, but can’t use DVD or USB for whatever reason (my usb stick does not starts, for example). This method will allow you to boot and install Windows directly from the hard drive. This guide involves accessing of hard drive from bootable Bart CD, Hiren’s Boot CD or other bootable solution (or putting into another working computer), preparing the hard drive, copyuing necessary files/folders, and installing Windows as usual.

Part 1: Preparing the HD with Windows 7 setup files.

– Connect the hard drive to another working computer.
– Format the hard drive to NTFS (Quick format works fine; multiple partitions also work).
– Copy the following from your Windows 7 disc:


Part 2: Making the HD bootable

Using Windows XP, Vista, or 7, open CMD as Admin (Windows key + R, type CMD, hit Enter)

Enter the following commands, (replace X with what applies to your hard drive):

 list disk
 select disk X
 list partition
 select partition X
X:\boot\bootsect.exe /nt60 X:

Exit and shutdown.

Note: If you’re working on a 32-bit system, and you want to install 64-bit Windows, you may get problems trying to run the last command (X:\boot\bootsect.exe /nt60 X:).
Solutions: Use a computer with a 64-bit version of Windows
OR a little trick that worked for me: If you have a 32-bit Windows 7 disc, you can copy bootsect.exe from that and replace the 64-bit one (boot\bootsect.exe).

Part 3: Booting and installing Windows

Place the hard drive back into the target machine. Make sure that the BIOS is configured to boot from the hard drive. If you did everything correctly, you should see “Windows is loading files” and setup will load (really fast, too, because it’s loading from the hard drive). Install Windows as usual (but don’t format your drive this time in the installer – otherwise it will erase the Windows 7 setup files too!).

Part 4: Final steps/housecleaning

We’ll have to quickly edit the boot menu once Windows is installed.

In Windows 7, hit the Windows key + R. Type msconfig, and hit Enter.
Click to the Boot tab at the top.
Click ‘Windows Setup (\windows)’, and hit Delete.
Click OK.
Click ‘Exit without restart’.

And lastly, delete the ‘Sources’ folder from your hard drive root (this will free up 2-3gb).
