As we know recently Apple formally released OS X Yosemite, its newest operating system for Mac computers. For most Mac users, the operating system has been much anticipated since it was first unveiled at the company’s annual developers conference in June 2014. The Yosemite OS is free, and is downloadable through the Mac App Store. 

Apple says that Mac computers from as far back mid 2007 will support OS X Yosemite, but as we have seen with any other new software releases, sometimes updating your old Mac to a newer software usually does not work out perfectly. One of the problem I encountered after upgrading my Macbook Pro to OS X Yosemite is that the volume icon at the top righthand task bar is greyed out and the audio sound does not work. Well if you ever encountered such similar problem, don't worry! Just follow the following steps carefully and it will fix the audio sound problem on your Mac without any hassle.

Before you start, open finder and on the empty search tab type Audio MIDI Setup, then select search:This Mac. Audio MIDI Setup icon will appear. Double click it and Audio Devices popup window will appear. Select Built-in Output and on the Format dropdown box click and select 48000.0 Hz instead of 44100.0 Hz. Once you have changed the Source format to 48000.0 Hz you will notice that the volume control icon at the top righthand task bar will be highlighted. Now just close the Audio Devices popup window and you are done.

Is your Mac slow at shutdown lately after upgrading your Mac OS X Mountain Lion 10.8 to Mavericks? Apparently some Mac users have reported this problem when trying to shutdown their Mac, such as having a grey screen with a spinning wheel rotating before your Mac actually shutdown. This can be a real nuisance having to wait for your computer to shutdown. Well in this article, I am going to show you how to resolve this problem and restore Mac OS X 10.9.1 Mavericks shutdown back to normal.


Disk permissions are a disk utility that helps to verify and repair your disk for permission differences. In Mac OS X 10.9.1 Mavericks or earlier version, when the user run disk verification or repair disk permissions, Disk Utility searches and reviews each of the .bom files in /Library/Receipts/ and compares its list to the actual permissions on each file listed. If the permissions differ, Disk Utility will report and list out the difference (and corrects them) if you use the Repair feature. You can try running repair disk permissions and see if that makes a difference in speeding up your Mac shutdown time.


1. Shut down the computer (by holding the power button).
2. Turn on the computer. Wait until you hear the boot sound.
3. Press and hold the Command, Option, P & R keys (simultaneously).
4. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
5. Then release the keys.

The PRAM should now be reset to the default values. Now try shutting down your Mac and see if it makes any difference on the shutdown time. Otherwise do a reset of the SMC which will help in your shutdown issues.


The SMC can cause problems related to your Mac built-in fan, lights, video display, power supply and general performance & functionality. So by resetting the SMC it might help to speedup your Mac shutdown. To reset the SMC, just follow the following steps.

1. Shut down your Mac.

2. Plug in the power adaptor onto your Computer.
3. Press Shift + Control + Option keys and the power button at the same time.
4. Release all the keys and the power button simultaneously.
5. Press the power button to turn on your Mac.

Now that your Mac is up and running, try shutting it down and see if it makes any difference. If you think the shutdown speed is still slow then just follow step number 4 below which will certainly restore Mac OS X Mavericks shutdown back to normal. But before you perform step number 4, please backup all your files to an External drive or USB pen drive.


Go to click the apple logo on the taskbar and click System preferences, then click Users & Groups. A popup windows will appear. Click the lock to make changes. Click the + sign located at the bottom of the popup window. Another small popup windows will appear. On new account, click the up/down arrow and choose administrator then enter your (new) name and password. Click create user then click on login options. On automatic login, click the up/down arrow and choose your new user name that you have created. Finally click the lock to prevent future changes and you are done. Now reboot your Mac and it will bootup as a new user. Once your Mac is up and running, you can reload all your files that you have previously backup from your External drive or USB pen drive onto your Mac. Once you have done that, you can try shutting down your Mac and you will notice how fast your Mac shut down.


IBoostUP is a system maintenance tool which can help fix your Mac problems such as slow performance, fans that are constantly running or system error messages that cause crashes. It is an easy friendly software to use and is a very small and fast to download software. You can download it for free from
