In previous versions of OS X, you were able to download via App Store and using the Disk Utility you could create a USB Installer. Mavericks is not as straight forward but still achievable.
What you need
- An 8GB or larger USB flash drive
- The Latest download of OS X 10.9.x Mavericks Installer from the Mac App Store.
- Latest version of Diskmaker X app
- An Admin account for use when creating disk
We won’t be covering the Diskmaker X option as it might be too easy for most OCD folks out there. Instead here’s some terminal action:
With the assumption you have the OS X Mavericks installer in your Applications folder and your USB Driver is formatted as OS X Extended (Journaled) with volume name “Untitled”. Type the following command into Terminal.
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ Mavericks.app –nointeraction
The command will erase the disk and copy the install files over. Go have a cuppa tea, this should take a bit.
When you try to boot 64bit Windows 7, or Vista SP1 and later, it requires an EFI firmware that is also 64-bit which the iMac lacks. The “fix” is to modify the ISO and reburn it.
0 – create 3 folders c:\windows64iso c:\windows64exe c:\windows64dvd
1 – download this (http://sergiomcfly.googlepages.com/oscdimg.exe) .exe file and put into c:\windows64exe
2 – put .iso you downloaded from ms (or an .iso you created from your retail windows disc) into c:\windows64iso and unzip it
3 – move .iso file out of c:\windows64iso and trash / delete it (won’t need it anymore)
4 – open a dos prompt in c:\windows64exe and type:
oscdimg -n -m -bc:\windows64iso\boot\etfsboot.com c:\windows64iso c:\windows64dvd\windows64dvd.iso
The windows64dvd.iso is the file you gonna burn onto a new DVD

Different versions of OS X have different formats for screenshots.
Mac OS X 10.2 (Jaguar): jpg
Mac OS X 10.3 (Panther): pdf
Mac OS X 10.4 (Tiger) and later: png
In Mac OS X 10.4 and later, the default screenshot format can be changed, by opening Terminal (located at /Applications/Utilities/Terminal) and typing in:
defaults write com.apple.screencapture type image_formatkillall SystemUIServer
OS X’s TimeMachine software had native support for network backup until the OS X Leopard 10.5.2 was released. Apple had its own reasons for the decision to remove network backup, but many of us would like to be able to still back up over the network.
How do you do it?
Fortunately there is an option to turn-on network support for TimeMachine by running the following command in terminal:
defaults write com.apple.systempreferences
We can finally see network hardrives in selection for backup places. The problem might seem solved, however this is just the beginning.
If you select a network drive for backup, you will see a very familiar message:
the backup disk image could not be created
TimeMachine only supports Mac OS Extended (Journaled) file system.
The solution is to create a place on the network, which will trick TimeMachine, into thinking that it holds data in Mac OS Extended (Journaled) file system. This trick is accomplished via copying a sparsebundle image (with special name) to a network share. You have to do following steps for to make TimeMachine successfully run a backup.
- Enable network hardrive support in TimeMachineMount network shared place for backup data
- Create a sparsebundle virtual image
- Copy the sparsebundle virtual image to the network shared place
- Set up TimeMachine for network backup
- Optimisation and other information
1. Enable network hardrive support for the TimeMachine software
Network hardrive support for TimeMachine is turn off by default. For changing this fact we have to type following command to the terminal:
defaults write com.apple.systempreferences
After that, you should see mounted network harddrive in TimeMachine’s locations for backup. If it is not this case, probably a restart is needed.
2. Mount Network shared place for backup data
If you have a shared location for backup data on Linux server, you can map the directory as a drive to Mac in Finder application. You have to do following steps:
Click GO and then “connect to server” in finder menu.
Write following path if your sharing is based on protocol samba (SMB): SMB://<IP_ADDRESS_or_COMPUTER_NAME>/<NAME_of_SHARED_PLACE> (e.g. SMB://192.168.1.25/Backup)
3. Create a sparsebundle virtual image This step is very important, because the TimeMachine doesn’t allow to backup data to a network drive, which has any file system except “Mac OS Extended (Journaled)”. So we have to create a disk image in “Mac OS Extended (Journaled)” format.
We have two ways to do it:
Open disk utility (Disk Utility) and create new virtual disk with following atributes:
Save As: <computer hostname>_<hex mac address of en0 interface>.sparsebundle (e.g. MacJohn_00ef9a048c4f.sparsebundle, if you forget to add .sparsebundle, it will be added automatically)
Volume Name: Backup of <computer hostname> (e.g. Backup of MacJohn)
Volume Size: the max amount of space you’re going to set aside for backups. (The volume size is depends on amounts of backup data. I have chosen 150 GB)
Volume Format: Mac OS Extended (Journaled)
Partitions: No partition map
Image Format: Sparse bundle disk image
Note: Disk utility automatically mounts the image to system volumes. We won’t need the image mounted, so we can safely unmount it.
The previous step can be done by one command in terminal: hdiutil create -size 150g -fs HFS+J -volname “Backup of MacAlec” MacAlec_00ef9a048c4f.sparsebundle
3. Copy the sparsebundle virtual image to the network shared place
You can copy the sparsebundle image to the network shared place using one of the following steps:
Copy the file to shared place by drag and drop operation in Finder application.
If you prefer to work with the terminal, you can type this instead: cp -r <sparsebundle_image_disc_location>/<computer hostname>_<hex mac address of en0 interface>.sparsebundle /Volumes/<NAME_of_SHARED_PLACE>/(e.g. cp -r /Users/Alec/Documents/MacAlec_00ef9a048c4f.sparsebundle /Volumes/Backup/)
Now we can safely delete the sparsebundle image copy on local computer once we are sure that it has been copied to the shared location.
Set up the TimeMachine for network backup
Open TimeMachine preferences (in SystemPreferences).
Click on Change Disk button for select the network drive for backup. (We have to select the “Backup”in our case.)
The first backup will start in two minutes. TimeMachine supports incremental backup, thus the first backup can take very long time (it is depends on network bandwidth and amount of backup data).
If you want to eject the mapped shared volume (/Volumes/Backup in our case), you have to do it within the two minutes countdown before backup starts or after backup is finished. TimeMachine has its own mechanism for mapping network hardrives, so a backup process isn’t interrupted by your hard drive mounting or unmounting. TimeMachine will automatically mount the virtual sparsebundle image, when the backup starts. You will see Backup of <computer_name> as connected device on your desktop, so you won’t need to manually mount the network hard drive later.
4. Optimisation and other information
in order to avoid long delays in backup process caused by Spotlight indexing, You should set the Spotlight application to not index the mapped network drive. Here’s how to remove spotlight indexing for a hard drive:
Open up the Spotlight software preferences in system preferences window
Move to privacy options and add the network drive by plus symbol
If you’d like to back up a little less often, you can modify the file
com.apple.backupd-auto.plist which is located in /System/Library/LaunhDaemons/ to change backup time interval. Open up the file in text editor and find the section: <key>StartInterval</key> <integer>3600</integer> You should change the number 3600 to the number of seconds of your backup interval.

The above may occur when the end-user took down the wrong email via Phone or while typing

Open up your Applications folder, go to Utilities folder and double-click on Terminal. You’ll want to move into the following directory:
/Applications/Microsoft Office 2004/
In Terminal type the following
cd “/Applications/Microsoft Office 2004/”
Make sure you aren’t running any office application at this point!
go one directory deeper ie. Office and delete the Office PID file.
Now close off Terminal and open up Word or Excel. You will now(hopefully) be prompted to enter in your license key and credentials
