This is a series of tips that cover Mac OS X client edition. Server forums cover Mac OS X server on the community.

Here is the series of tips for related Macs. 10.6,10.7, 10.8, 10.9, 10.10,10.11,

10.12 ,10.13, 10.14 Mojave, 10.15 Catalina , 11.0 Big Sur.


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 includes many full upgrade installer links on https://support.apple.com/en-us/HT211683


Note: APFS came about with High Sierra, and Mojave continues the practice of auto-reformatting drives into APFS that are solid state like flash drives from HFS Journaled. If you need to downgrade to an older system than High Sierra, you will need to reformat the drive again, or leave a partition with the old formatting available.


Apple released for 10.14.6 users, 2020-003 Mojave security update. If running an earlier version of 10.14, run the 10.14.6 Combo update first.


Apple recommends you have these Macs according to: https://support.apple.com/kb/SP777?locale=en_US


  • MacBook (Early 2015 or newer) [model identifier 8,1 or later]
  • MacBook Air (Mid 2012 or newer) [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, and is the only Mac that shipped with 10.6 that can install Mojave. 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.


Mysql python conda.

September 30, 2018 driver additions from third party update pages:

HP, and Samsung (HP has become the download site for at least some Mojave Samsung printers, if you have Samsung see if any are Catalina compatible)

Silverfast.


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.

Check compatibility

How To Upgrade To Os X Mojave

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.

To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs macOS and related firmware updates.
