Upgrading to Mojave (Mac OS 10.14)
This is a series of tips that cover Mac OS X client edition. Server forums cover Mac OS X server on the community.
See special note about resetting the SMC during updates and upgrades, later in the tip.
is an article I wrote that everyone updating their Mac should read. No update should be ventured into with operating systems or software without first ensuring your data is backed up in two separate places. Slowing down of your Mac should not lead you to assume an update will fix everything. First isolate why your Mac is slowing down or crashing before installing anything new.
Apple recommends you have these Macs according to: macOS - How to Upgrade - Apple
- MacBook (Early 2015 or newer) [model identifier 8,1 or later]
- MacBook Air (Mid 2012 or newer) [model identifier 5,1 or later]
- MacBook Pro (Mid 2012 or newer) [model identifier 9,1 or later]
- Mac mini (Late 2012 or newer) [model identifier 6,1 or later]
- iMac (Late 2012 or newer) [model identifier 12,1 or later]
- Mac Pro (Late 2013; Mid 2010 and Mid 2012 models with recommended Metal-capable graphicscards) [model identifier 5,1 or later]
bracketed items in quotes were added for additional identification purposes. Your Apple menu -> About This Mac -> System Report or System Profiler gives you the model identifier.
All of the Macs that are older than 10.11, need to be updated to 10.11 first before installing Mojave.
The oldest MacBook Air, Mac mini, and iMac which can upgrade to Mojave shipped with 10.8, Mountain Lion.
The oldest MacBook Pro which can upgrade to Mojave shipped with 10.7, Lion.
The oldest MacBook had Mac OS X 10.10 installed.
The oldest Mac Pro on the list above with the compatible graphics cards, had 10.6 originally installed. Before upgrading to 10.7 or later, read this tip as Apple has not reintroduced a series of software that made older Mac compatible software compatible with Intel Macs since 10.6.8's release.
Apple released Mojave on September 24, 2018. Reports from:
earlier than that date were made with pre-release Mojave versions and can not be relied upon.
September 30, 2018 driver additions from third party update pages:
10.14.3 was released January 22, 2019. Note, some users are reporting 10.14.3 will not successfully apply as an update without an SMC reset as described how to do in this link: https://support.apple.com/en-us/HT201295
Frequently both updates and upgrades will require multiple reboots to successfully apply. Do NOT become impatient if you find the screen go blank during the update or upgrade process. If you press the power button to shut it down while it is rebooting for the update or upgrade, it may quit the process, and leave you stuck.
Use the macOS Mojave forum for operating system specific questions of other end users such as yourself.
are directions for creating a separate partition that will allow you to dual boot into an older operating system
if you find something not compatible with the current. Once you install the older operating system, you can use the Startup manager to dual boot to the older system.
Unsupported Macs may have Mojave installed with a patch from http://dosdude1.com/mojave/
This is at your own risk. Follow the directions given by the patch author.
