Preparing for macOS 10.13 High Sierra / macOS Server 5.4-5.6.3

WARNING: As of 21st April 2022 OS X Server/macOS Server is no longer available as Apple has discontinued it.

Here is a check list to do before installing macOS 10.13 High Sierra / macOS Server 5.4-5.6.3:

Check whether you have a compatible Mac from this list:
- MacBook (Late 2009 or newer)
- MacBook Pro 13" (Mid 2010 or newer)
- MacBook Pro 15" (Mid 2010 or newer)
- MacBook Pro 17" (Mid 2010 or newer)
- MacBook Air (Late 2010 or newer)
- Mac mini (Mid 2010 or newer)
- iMac (Late 2009 or newer)
- Mac Pro (Mid 2010 or newer)
NOTE: All Xserve models are now unsupported.
NOTE: If you are not sure whether you have a compatible Mac check our High Sierra FAQ before proceeding.
Check you do not need any of the following as Sierra does not directly include them:

Safari 13 for High Sierra does not support .safariextz packaged Safari Extensions - see our Catalina Third Party Product Compatibility Information article
Safari in High Sierra does not support legacy NPAPI browser plug-ins except for Adobe Flash
Messages support for AIM, Yahoo and Googla Talk accounts - Jabber is still supported
PPTP VPN support
Rosetta for running PowerPC software - Mac OS X 10.6 Snow Leopard users only
Web Sharing - see our High Sierra FAQ for alternatives or buy/use macOS Server 5.4-5.6.3
Xgrid Sharing - see our High Sierra FAQ for alternatives

If you have a third party SSD installed in your computer check to see if it needs a firmware update before installing High Sierra.
Make sure you are connected to the internet (preferably with a fast connection and with a large or no data cap in place).
Make sure you have an Apple ID (use the iTunes or App Store application to create one if necessary e.g. go to Macintosh HD > Applications > App Store > Store menu > "Create Account…" to get started if you don't have an Apple ID).
Consider whether you want the Mac App Store Apple ID to be the same for services such as iCloud, iTunes, etc if you are going to use them.
Make sure your that Apple ID "account" has enough credit on it or has a credit card on file (with enough credit on it).

Go to Macintosh HD > Applications > Utilities > Disk Utility:

Select the volume under the disk you are going to use for High Sierra on the left, check at the bottom that it states "Format: Mac OS Extended (Journaled)". If it doesn't state "(Journaled)" you will need to turn journaling on by going to File menu > Enable Journaling.
Repair your boot disk's permissions.

Backup and/or clone your computer.

Check that your favourite software is High Sierra compatible.
Temporarily disable any third party disk encryption software.
