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

You need a Apple iMac that has a 64 bit Intel i3, i5, i7 or Xeon processor, manufactured from late 2009 onwards and supports 64 bit EFI.
A Macbook from 2009, a MacBook Pro from mid-2010, a MacBook Air from late 2010, a MacMini from mid-2010 ,or a Mac Pro from mid-2010.
For memory, you need at least 2 GB of RAM (4GB recommended). For hard disk space, you need at least 8.8 GB of free space to install Sierra.
For additional requirements, see Apple's Technical Specs.

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

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 Install macOS High Sierra installation file you downloaded:

a) Locate the Mac OS X High Sierra 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\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ High \Sierra.app --nointeraction

5. How do I install High Sierra?

a) Open the AppStore icon in the dock.
b) Click on Sign In link in the Quick Links.
c) Click on macOS High Sierra icon to purchase (it is free) and download the program (previous versions are available under Purchases).
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 macOS Sierra 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 macOS High Sierra 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.

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 macOS High Sierra?

Mac OS 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 High Sierra:

For example:
a) Office Applications. For Microsoft Office, you need at least Office 2011 ,365 or 2016. You can also use iWork, Open Office, Libre Office and Neo Office.
b) Apple Garageband, iMove, and Photos are available from the App Store.
c) Adobe Creative Suite. Use Creative Cloud.
d) Media Players. As well as iTunes and Quicktime, you can download new versions of players such as VLC Player, Real Player and Flip4Mac.
e) Accounting. Quicken Essentials will work on Mac OS. Alternatives include Home/Business Accountz and IGG Software iBank.
f) DTP. See Adobe CC InDesign, and for Quark XPress you need version 9 or later.
g) Graphics. See Adobe CS6 or later for Photoshop, also try Photoshop Elements 13 or 14 (make sure Java 6 is installed).
h) Games. Games on the App Store or from Steam Powered.
i) To play commerical Blu-Ray discs, you need MacGo Blu-Ray Player.
j) Database. Try FileMaker, Records for Mac and others.

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.

11. The Java client is missing, where can I download Java from?

Boot Manager called rEFInd which allows you to boot and choose an OS to boot from.
