macOS version 10.14.0, called "Mojave," was released on 2018-09-24.
It is a free update to 10.13 High Sierra.
This note describes how to update a computer from an older version of macOS to OS X 10.14 Mojave.
Here is a review of Mojave from Ars Technica .
I have not installed Mojave on any computers yet.
A friend who tried to upgrade two computers to Mojave had one success, and one disastrous failure.
I am waiting until I have more confidence before I install Mojave on any computer.
Mojave ships with new Macs.
The latest version of Mac OS X is version 10.14, "Mojave", released in September 2018.
New Features of Mojave
- dark mode (optional)
- desktop pix changing by time of day (optional)
- finder changes
- QuickLook changes
- screenshot changes
- Continuity Camera: photo integration with iPhone
- 32 people in FaceTime
- some apps from iOS now on Mac
- App Store changes
- emoji in Mail
- APFS for hard drives and Fusion drives
Should I Install Mojave?
WAIT until the OS is debugged before upgrading.
If your computer is working now, there is no urgent need to change your OS,
until you want the new features,
or continuing security updates (High Sierra, Sierra, and El Capitan are still getting security updates).
Apple will probably drop support for older versions of OS X eventually.
Usually they support the current version and the previous version.
Using an unsupported OS will still work,
but if security problems are found in an unsupported version, Apple usually does not patch them.
Eventually, companies will write software that requires features of the latest Apple OS,
and someday you may want to buy and use some of that software.
If your current Macintosh fails and you have to buy a new one,
you'll end up migrating to Mojave whether you were ready or not.
This happened to me.
(10/01) Emacs 25/26 and with it, Aquamacs, are incompatible with macOS “Mojave”.
This is a show stopper for me.
Check MacInTouch for the latest status. As of 10/01/18 it reports problems with
A friend reported being unable to upgrade an iMac, had to restore from backup.
Other users have reported problems installing Mojave, or network failures after installation.
What you Should Do Now to Get Ready for Mojave
to keep all Apple software up to date, including the OS.
- Apply all free updates to other software you use.
- Set up an external hard drive and use Time Machine.
- Add more RAM if you can.
- Fix damaged and duplicate fonts.
If you are running a version of Mac OS X earlier than Snow Leopard, you will have to install Snow Leopard first.
You can buy an installer disc for Snow Leopard from Apple's web site for $20.
Who Can Update
Not everyone can use the new OS version.
Only fairly new Macs can run Mojave.
See the list online at the Apple web site that specifies what Mac models can run Mojave.
If your computer does not meet these requirements, stick with the latest Mac OS X you can run.
(I have a Mac Mini that is too old: "late 2012" is the requirement, and October 2012 doesn't qualify. I think the issue is the graphics card.)
- You need at least 2GB of memory, preferably more.
If you depend on PowerPC programs, the latest version of OS X that you can run is Snow Leopard,
since Lion, Mountain Lion, Mavericks, Yosemite, El Capitan, Sierra, High Sierra, and Mojave do not support Rosetta, the PowerPC emulator.
See the Frequently Asked Questions section about Mojave.
In particular, pre-Lion Quicken, Microsoft Office 2004, and some features of Adobe CS3 will not run on Mojave.
(See Adobe article.)
Stick with OS X 10.6.8a until you upgrade these applications.
You could install VirtualBox (free) on your Mac, and install 10.6 into a virtual machine, and update it to 10.6.8a,
and run your PowerPC programs under the emulated OS.
I tried this on Yosemite, and it worked.
If you depend on the Classic environment to run Mac OS 9 programs from the 1990s, stick with OS X 10.4.
If you have a Mac with a PowerPC processor, Mojave won't work on it.
Stick with OS X 10.5.8.
You can't install Mojave over an ancient version of OS X:
Apple's license terms specify that Mojave is only for Macs that have
Lion, Mountain Lion, Snow Leopard, Mavericks, Yosemite, El Capitan, Sierra, or High Sierra installed, and the installer enforces this restriction.
Old printers and scanners may not work if the manufacturer has not updated the driver software.
Those with PowerPC or 32-bit drivers will not work.
Plan your install
When you decide to install Mojave, do it carefully.
You may find that there are issues that affect you: do your homework.
Check MacInTouch to see if there are problems with macOS 10.13 that affect you.
Make sure you back up your entire disk before starting to install Mojave.
Preferably to more than one place.
Make a list of the hardware you depend on, and search the web to check that each device will work.
Older printers and scanners can have issues.
Leave yourself enough time.
Upgrading will tie up your computer for a big part of a day.
Installing takes an hour or two,
but then your computer will be very slow until it re-does the Spotlight index and does a big backup up to Time Machine.
Particular issues before upgrading
Here is a partial list of minimum program versions needed for Mojave. ================ check
For other programs, check product websites.
|Microsoft Office||2016||See below.|
|Quicken||2018||$35/yr. See below.|
|Adobe Acrobat||XI Pro
||Support ended in 2017. Supposedly still works. See below.
||Known problems. See below.
||Known problems. See below.
|Suitcase Fusion 7||18.2.4||Photoshop and Illustrator issues. $60 upgrade to Fusion 8.|
|Apple XCode||9||free with registration|
|Apple OS X Server||5.4|
System Integrity Protection has new security features that restrict what applications can do.
Mark Aldritt's blog has an informative article,
which pointes out that AppleScript will not support Scripting Additions not provided by Apple, and that
applications will need permission to send AppleEvents to other applications.
Renting Instead of Buying
Adobe no longer sells regular application versions of Photoshop and Illustrator.
Instead they rent
you a Creative Cloud subscription.
Stop paying, the apps stop working.
They tell you that one advantage is that you'll get bug fixes and new features whenever they decide to release them.
(There are a lot of tricky deals, initial teasers, different bundles.
You could pay $20/app/mo or $600/yr for all CC apps.
Adobe also sells Photoshop Elements as a non-cloud application for $70 one-time.)
Similar deal for Adobe Acrobat.. Acrobat Pro DC rents for $179/yr for the rest of your life, for 2 users.
(Acrobat XI Pro may still work on Mojave.)
You might be able to buy a lifetime copy for $449, but websites don't say how many computers are covered.
If you search the web for replacement products, there are some listed.
PC World suggests Nitro Pro 11, $160 lifetime for up to 10 users.
There are alternatives to Adobe products, such as much less expensive
Affinity Photo and Affinity Designer.
There are also free programs such as Polarr Photo Editor and GIMP.
With any of these replacements, you have to learn how to use new programs, and worry about compatibility.
Microsoft wants to rent you "Office 365."
(Again there are multiple deals: for about $70/yr/computer you can get the whole suite.
You can also buy non-cloud Office 2016 Home & Student for $150 one-time. This is what I did.)
Quicken 2007 (Lion update) sort of works on Mojave; won't make a backup to an APFS volume.
Since this is 32-bit software, it won't run on the macOS scheduled for 2019.
Quicken wants to rent you Quicken 2018 for Mac for $35/yr.
This is a show stopper for me.
Programs that will not be upgraded: Some device drivers: check with your device manufacturers.
The free software CUPS drivers may work for some printers.
Gutenprint was marked as incompatible.
Make sure your printers and scanners will be supported.
Some manufacturers don't release updated drivers for their printers for months after a new OS X release.
Clean up and update software before installing.
(If your Mac is running a very old version of OS X, you must install Snow Leopard 10.6.8 first,
in order to get a version of Apple App Store that can download Mojave.
Here is Apple's how to upgrade page.)
Download Mojave from free.
This downloads a large file, the Mojave Installer, to your disk.
You can create a bootable installer volume on a USB key using
(But see the TidBits article "Previously Downloaded OS X Installers No Longer Work".)
Apple's license terms say you can update all your computers with one purchase.
. It is
- Get the applications on your computer ready for 10.14: apply the latest fixes.
- Delete junk files. Carefully.
- Delete Safari, iTunes, and Firefox caches, so your backup will be faster.
If you have customized your desktop background or screensaver, write down your settings.
Some Apple-provided pictures may not be available in the next version.. make a safe copy of anything you will want after upgrading.
- Empty the Trash.
- Clean up damaged and duplicate fonts.
- If you use Apache, save a copy of /etc/apache2/httpd.conf.
If you installed modules via CPAN, Macports, or Fink, make a list of them. In a Terminal window, type
perldoc perllocal | grep :: > cpan_modules.txt
port -qv installed > macports_packages.txt
- Have your software license keys handy in case you have to re-authorize products.
- De-authorize Adobe Photoshop and Illustrator.
- De-authorize your computer from iTunes.
Backup and prepare.
- If you use MySQL, backup the database with mysqldump databasename > db.sql
BACK UP YOUR HARD DRIVE to an external disk.
I used SuperDuper to clone my whole drive.
Some cautious people make two backups.
If you installed a third-party Solid State Disk (SSD),
check the manufacturer's website to see if you need to update its firmware to work with Mojave.
If you connect your Mac to the network using WiFi, select
and delete any WiFi networks you don't want to use.
(I forgot to do this, and my computer connected to a very slow network, which slowed down my install.)
The best way to handle Macports is to uninstall all the old ports and reinstall after updating the OS.
After you list your installed ports, type
sudo port -fp uninstall installed
in a Terminal window.
- If you use a wireless mouse or keyboard, put in fresh batteries.
- Set screen saver to NEVER, and turn off Time Machine.
- Dismount and unplug or power off external drives.
Run the macOS 10.13 installer.
If FileVault is enabled on your computer, the installer will ask for a password to unlock the disk.
It will run for about 15 minutes, then reboot, then run for about an hour, then reboot again.
(The "time remaining" will show wildly varying estimates as the installer proceeds.
Don't panic if you see a gray screen with "30 minutes remaining" for an hour.
Just let it run.)
As the update finishes, it will ask you for your AppleID password. ================ check
If Mojave asks you if you want to enable Desktop and Documents folder syncing to iCloud,
the safest thing to do is to say NO.
If you say YES, these folders will be backed up in iCloud and available on all devices, which you may not want,
and saying YES may also enable "Optimize Storage" which will delete files from your computer's drive if it gets too full.
Adam Engst's TidBITS article on Optimized Storage is very helpful.
to update to latest versions of Apple software,
then run it again to make sure all software is updated. (about another hour)
If you just downloaded the OSX installer from the Apple Store, you will have the latest version of OSX,
but this step may find additional application updates.
Do a "smoke test" to verify that your computer is working OK.
Make sure the applications you depend on are still working.
Try out the applications from Apple that were updated with the OS.
If you have trouble, restore your backup and go back to the old OS version.
When you attempt to re-authorize Adobe Photoshop and Illustrator, or the first time you execute them,
you may see an alert box that tells you that you have to install Java 6 first (even if you have Java 8 installed). ================ check
Click "more Info" and download and install the update. See above for a gotcha regarding the "quarantine" switch.
Re-authorize your computer in iTunes.
Wait for Spotlight to finish indexing (may take several hours).
Performance will suck till it finishes.
Turn on Time Machine and start your backup.
You don't have to repair disk permissions with Disk Utility any more. In fact, you can't; the option is gone.
Restart the computer. Often this speeds things up.
Post Install Tasks
Once you are satisfied that your computer works acceptably,
and you are going to stay on Mojave,
you can make some adjustments.
If your computer seems slow or buggy, try zapping the PRAM.
If you have purchased applications that are OS version specific, like Cocktail, buy updates and install them.
Clean your font caches by issuing the Terminal command sudo atsutil databases -remove and restarting.
If FileVault was on, it will be on after upgrading. Check to make sure.
In Fact, check all the System Preferences. Once in a while something is changed by an update.
You will probably want to set up per-user customizations, such as your desktop background and screensaver.
After each new OS generation this is something of an adventure; functions get renamed and moved around.
I really hate the CAPS LOCK key, so I disable it.
In Mojave, this is done by opening
and changing the action for CAPS LOCK to "No Action."
(I had set this on Yosemite and it was carried over by the upgrade process... hope this works for Mojave too.)
, I uncheck "Scroll Direction: natural" .. it seems UNnatural to me after 30 years.
(I had set this on Yosemite and it was carried over by the upgrade process... hope this works for Mojave too.)
I disable or silence most Notifications.
Under Mojave, Spotlight "shows suggestions from the Internet, iTunes, App Store, movie showtimes, locations nearby, and more."
To do this, it sends your location and query to Apple servers.
You may wish to change this if you are required to keep some information private.
Change it in two places:
uncheck "allow Spotlight Suggestions" in
and uncheck "Safari & Spotlight Suggestions" in
Some kinds of security certificates are no longer accepted. These are the ones using SHA-1, which is deprecated.
Check that your printers work.
If your printer will not work, you may be able to get it working by selecting
deleting the printer and adding the printer again:
for some printers, this will trigger running to get new printer software.
For other printers, you will have to download the correct printer driver from the manufacturer's web site.
If you have a scanner, plug it in and power it on. Mine worked fine.
If the scanner appears in Image Capture.
For other scanners, you will have to download the correct scanner driver from the manufacturer's web site.
If manufacturer-supplied software is not available, and Image Capture does not provide enough features,
you may be able to get it working by purchasing and installing VueScan.
, remove it, and add it again.
For some scanners, this will invoke to add a driver that will let you operate the scanner with
In Terminal, type the command java.
If you don't have Java 8 installed,
this action will bring up a dialog box: click to bring up the Oracle JDK installation page in a web browser,
and trigger the installation of the Java 8 JDK from Oracle over the Internet. ================ check
Java is needed for Eclipse and for other Mac applications,
such as OpenOffice and some Adobe products, and VPN clients such as Cisco.
Java is not dangerous, if you use it to run code you trust: using it to run web page animations has had some problems.
If you use your computer for programming, install the (free) Xcode Developer Tools
by typing xcode-select --install in a terminal window,
or by installing the whole Xcode package using the App Store.
Then type sudo xcodebuild -license in a terminal window to accept the license.
MacPorts: see my instructions for MacPorts page.
Basically the procedure is to list your ports and uninstall them before upgrade,
install the OS,
and reinstall your ports.
Set PERL5LIB=/Users/myname/bin:/opt/local/lib/perl5/site_perl/5.26 or installs will fail with messages about variants.
You will need to disable SIP to complete these installs.
Version 8.0.1 appears to work on Sierra and Mojave. ================ check
Perl 5.26.2 is installed by MacPorts. See my instructions for CPAN. ================ check
Apache web server:
Apache 2.4.28 is provided with Mojave, but is not automatically started and there is no System Preferences interface to enable it. ================ check
The new OS install will not carry over your old Apache customizations.
diff /etc/apache2/httpd.conf against your saved copy and edit as necessary.
Start Apache using the terminal command sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist.
The -w means make it permanent across restarts.
PHP 5.6.30 is shipped with the OS but disabled in httpd.conf, same version as for Sierra. ================ check
I sometimes enable PHP in order to debug programs that will be deployed in safe environments on other computers.
If you enable it, be aware of the risks of making PHP available on the Internet from your Mac, and track and install security updates.
Screen saver: if you patched the duration of a screen saver slide, as I did, you will have to reapply the patch.
Login screen: if you replaced the login screen background, as I did, you will have to reapply the patch.
After all installations are done, re-enable SIP by booting into the recovery environment and typing csrutil enable .
New Features and Changes
Bugs/Gotchas in Mojave
lot of features removed.
even more will be removed in 10.15.
Planning for the next version
Keep a list of the software and devices you use and depend on, so you can check that they are supported.
The next macOS version, macOS 10.15, will probably release in Fall 2019.
Apple has announced the next version of macOS won't support 32-bit execution at all.
Start planning. To list the 32-bit programs on your system,
there is a section in the System Profiler that lists Legacy Programs.
