Create a Mavericks USB Key

Something that has been around for  while, but I’ve just stumbled across it, is Diskmaker X

This nifty app will do all the donkey work in creating a bootable Mac OS X USB Key, you just need to following

1. Mavericks Installation app from the Mac App Store

2. Diskmaker X app from their website

3. an empty 8GB USB Key

 

Once you have downloaded the Mavericks app from the App Store and Diskmaker X from their website, then insert your USB Key into your Mac

Run Diskmaker X

When prompted, choose 10.9

It will then look for your Mavericks app, when it finds it, choose ‘Use this copy’

Then if you are using an 8GB USB key, then choose  ‘An 8GB USB Thumb Drive’

If you are using a partition on a larger drive, then choose ‘Another kind of disk’

Confirm the choice of disk by clicking on ‘Choose this disk’

When it warns you about erasing the drive, confirm that you wish to continue by clicking on ‘Erase and create the disk’

You will then be warned that you will need to input your admin password, so click ‘Continue’ and then enter your admin username and password when prompted

The process is fully automated, so from now until completion it will take around an hour, maybe longer on slower machines, you will get a dialog box when it has completed, confirming this and asking you for a donation, it’s not compulsory, but as it is quite a useful app, its always good to encourage future development, so please consider it.

 

You can then boot into the USB from the Startup Disk option in System Preferences, or by holding down ALT when the machine boots up

 

Enjoy

Mac Mail – Ghost Unread Count

Mail

So, after having the problem with ghost unread mail appearing on my iPhone, I then had to deal with this on the Mac Mail app.

This has happened before, and can usually be simply fixed by clicking on the offending folder (usually Inbox), then clicking on ‘Mailbox’ in the menu bar, then clicking on ‘Rebuild’

it takes a little while but usually resolves the issue, this also works pretty well if the inbox is showing no messages at all, just a blank window, anyway, back to the problem, so this time, this didn’t work, so I had to resort to a more drastic rebuild.

First, quit Mail

Once it is no longer running, click on Finder

then press SHIFT, CMD, G

then paste in the following location and click on Go

~/Library/Mail/V2/MailData

In that folder you need to remove all files starting with Envelope (usually Envelope Index, Envelope Index-shm, Envelope Index-wal), normally, I move these to the Desktop until everything is all working again

Once there are no files starting with Envelope in that location, then click on Mail to Rebuild the Index, Once this has finished, your mail should be back to normal, no missing unread items.

 

Re-enable Java 6

Command Line System ConfigIf you are running Mac OS X 10.8 and have installed Java 7, as well as the latest Java Update from Apple (Java 2013-002) and have found that some things don’t work with Java 7, and you wish to change back to having version 6 as your default Java installation, then you can download the script – Enable_Java6.sh from the link below

Enable_Java6.sh

Extract the file, copy it to the desktop

Open Terminal & type the following

cd ~/Desktop
sudo ./Enable_Java6.sh

this script only takes a second to run, once its complete, go to this website to check the version of Java that you have enabled

If you wish to undo this and switch back to Java 7 then you can enter the following into Terminal
