3. What are the minimum requirements to run Yosemite on my iMac?

You need a Apple iMac that has a 64 bit Intel Core 2 Duo, i3, i5, i7 or Xeon processor, manufactured from late 2007 onwards and supports 64 bit EFI.
For memory, you need at least 2 GB of RAM (4GB recommended). For hard disk space, you need at least 8 GB of free space to install Yosemite.
For additional requirements, see Apple's Technical Specs.

4. How do I create a bootable USB disk with Yosemite?

You can no longer create a bootable DVD but you can create a bootable USB stick. You can create it from the disk image from the OS X Mavericks installation file you downloaded:

a) Locate the Mac OS X Yosemite installation file in the Applications folder. If it is not there, download it again from the App Store.
b) Open the Terminal program and start a shell,
c) Insert a blank USB disc in your Mac.
d) Enter the following command in the Terminal window shell. Replace untitled with the name of your USB Stick:

sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction

5. How do I install Yosemite?

a) Open the AppStore icon in the dock.
b) Click on Sign In link in the Quick Links.

d) The program may take an hour or so to download (approx 4 GB).
e) Open the Applications folder and you will find the Install Mac OS X Yosemite icon.
f) I would recommend backing up this file to an external disk if you want to use it again later and prevent having to download it again.
g) Run Install Mac OS X Yosemite to begin installation and follow the prompts.

6. How do I use the Recovery feature?

When you boot up, press the Command-R key combination to enter HD Recovery mode. You can then select one of the following options: Restore from Time Machine Backup, Reinstall Mac OS X, Get Help Online (using Safari browser) or load the Disk Utility.

Restore, reinstall, help and disk utility

a) Time Machine Backup. This allows you restore an entire backup of your Mac OS X installation, applications and files back to a hard disk partition of your choice.
b) The Reinstall Mac OS X will reinstall Mac OS X but it doesn't include all the files to restore, so it will need network access to download the necessary files from the AppStore.
c) Get Help Online will open Safari so that you have access to the internet to access instructions and other information to allow you to restore your Mac.
d) Disk Utility will open the disk tool to partition or repair your hard disk.

7. What applications can I run on OS X Yosemite.

Mavericks can run any Universal or Intel compiled applications. Most of the apps for Mac OS X Lion or later should be able to run on Mavericks:

For example:
a) Office Applications. For Microsoft Office, you need at least Office 2011 or Office 365. You can also use iWorks 9.1, Open Office, Libre Office and Neo Office.
b) Apple iLife. You need a least iLife '11 to run.
c) Adobe Creative Suite. Use Creative Suite 5 or later (there are some compatibility issues with Contribute CS4).
d) Media Players. As well as iTunes and Quicktime, you can download new versions of players such as VLC Player and Real Player for Lion. Flip4Mac is coming soon.
e) Accounting. Quicken Essentials will work on Lion but not the older Quicken versions. Alternatives include Home/Business Accountz and IGG Software iBank.
f) DTP. See Adobe CS4 or later for InDesign, for Quark XPress you need version 9 or later.
g) Graphics. See Adobe CS5 for Photoshop, also try Photoshop Elements 10.
h) Games. Games on the App Store or from Steam Powered.

A complete list of tested applications can be found on RoaringLion.

8. How to I accessed shared resources on Windows systems from my Mac?

Windows computers uses a protocol called SMB (Simple Message Block) and CIFS (Common Internet Filing System) to share resources such a files and folders. On a Windows computer, this uses the Microsoft Client for Networks. Shares can be accessing using the format \\computername\sharename.

Apple Macs can also use SMB/CIFS. To access a Windows share, select CMD+K (to select Go to Server) and enter smb://servername/sharename (you can use an IP address instead of a servername). If you forget the smb: part, it will use the default AFP (Apple Filing Protocol) which will only work on shared Mac resources.

To configure SMB or CIFS, make sure you have configured the Computer Name (hostname) correctly on the Mac (preferably with no spaces) in the Sharing control panel and enable Windows Sharing or File Sharing. In Options, enable Shares file and folders using SMB (Windows). You will also need to create and enable Accounts and set up Read/Write permissions to allow access to shared folders.

To configure membership of a Workgroup and set up a short NetBIOS name, you can do this in the Networks control panel. Select the adapter (e.g. Ethernet), click on Advanced and select the WINS tab to configure a NetBios Name and Workgroup. Not setting the workgroup name, can prevent access to SMB shares or logging in over the network.

SMBX in Mac OS X supports SMB1 and SMB2 but not the old NT Domain Controller features (most people will not use these features any way). Apple has replaced SMB with SMBX due to issues with the GPLv3 licensing requirements.

Use the terminal command 'smbd' to view logs when using smb client.

9. How do I secure may Mac from hackers, viruses and other threats?

You can do several things, including enabling the Firewall in the Security control panel. Make sure that Software Updates are regularly checked and applied and install some security software to check against viruses and malware:
a) McAfee LiveSafe or All Access for Mac which includes SiteAdvisor, a Firewall and anti-virus products.
b) VirusBarrier and Internet Security Barrier products from Intego.
c) The free ClamXav anti-virus scanner.
d) Norton Security from Symantec.
e) Kaspersky Total Security Multi-Device.
f) F-Secure Safe for the Mac.
g) Use Gatekeeper, and restrict app download from just the App Store or from trusted identified developers.

10. How do I check that my NAS backup device is compatible?

NAS (Network Attached Storage) devices are very useful for storing large amounts of data and for backups. OS X Lion has changed the protocols for AFP Netatalk to 2.2 which may break older NAS devices. To ensure that you can connect to your NAS with Lion, please update the firmware and software for your NAS devices. For example, EMC have released a code upgrade for their SAN Celerra. There are also updates for the AFP DHX2 Authenication for Synergy DiskStation Manager , QNAP and DROBO products. Use CIFS protocol instead of SMB for faster file access.
