“This copy of the Install OS X Mavericks application can’t be verified” FIX

by

Just a quickie fix here.

If you are experiencing the above error whilst trying to do a fresh install of OS X Mavericks (from a USB stick) there is a good chance all you need to do is change the date that your machine believes it to be.

So for example it is now 17.15 hrs on 15th March 2014.

To fix this error go to the ‘Utilities’ Menu and run ‘Terminal’ (from within the Mavericks’ installer).

Once in terminal enter the date as follows (of course making it the correct current date and time, this simply illustrates the format)…

date 031517152014

Press Enter.

Now close ‘Terminal’ and attempt the fresh install.

Things should now go your way!

Good luck.

Show hidden files Mac OS X 10.7 Lion and 10.8 Mountain Lion

I have found that on ocassion you may need to see some of the hidden files and folders in OSX, mainly for troubleshooting. When enabled things can appear very messy and untidy so in my opinion it is best to make things visible, then when you are done, hide them again.

Good luck.

To enable hidden files/folders in finder windows:

– Open Finder

– Open the Utilities folder

– Open a terminal window

– Copy and paste the following line in:
defaults write com.apple.Finder AppleShowAllFiles YES

– Press return

– Now hold ‘alt’ on the keyboard and right click on the Finder icon

– Click on Relaunch

You will now see all the hidden files and folders. Once you are finished, perform the steps above however, replace the terminal command in step 4 with:

defaults write com.apple.Finder AppleShowAllFiles NO
