What you Should Do Now to Get Ready for Ventura

Who Can Update

Not everyone can use the new OS version.

Plan your install

When you decide to install Ventura, 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 13.0 that affect you.

Make sure you back up your entire disk before starting to install Ventura. 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 Ventura. For other programs, check product websites.

Adobe: Renting Instead of Buying

Adobe no longer sells regular application versions of Photoshop, Illustrator, and Acrobat. 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, plus $180/yr for Acrobat. Adobe also sells Photoshop Elements 2020 and Premiere Elements 2020 as non-cloud applications for $100 each one-time, or both for $150.)

There are alternatives to Adobe products. I am using Affinity Photo and Affinity Designer. I need a replacement for Adobe Acrobat: PDFPen ($80) is looking attractive. There is a program called PDF Expert but its web site does not say how much it costs. I am not going to install it just in order to find out.

Microsoft: Renting Instead of Buying

Microsoft wants to rent you "Office 365" for $70/yr, $100/yr for up to 6 people. You can still buy a "forever" Home and Student version of Office 2019 for about $130.

Quicken and Banktivity: Renting Instead of Buying

Quicken has moved to a rental model also. There are various versions, Starter, Deluxe, Premier. Banktivity 7 works for me and is not rental software. Update: Banktivity 8 is going to a subscription model as of 2021. Shucks. Maybe I will look at GNU Cash.

Installing Ventura

(I have not installed Ventura yet, so everything below this point will need updating when I do.)

  1. 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 Ventura. Here is Apple's how to upgrade page.)
    • You can download the Ventura Installer from  ► System Settings...=>General=>Software Update. It is free. This downloads a large file, the Ventura Installer, to your disk. You can create a bootable installer volume on a USB key using these instructions. (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.
    • Get the applications on your computer ready for 13.0: 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.
    • Have your software license keys handy in case you have to re-authorize products.

    For Programmers

    • If you use MySQL, back up your databases with mysqldump databasename > db.sql. Then stop MySQL.
    • 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
    • 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.
  2. Backup and prepare.
    • 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 are using an anti-virus product like Microsoft Defender ATP, disable it, or installation will fail. Some anti-malware programs see the utility that converts HFS to APFS as malware, and prevent it from running. Since most anti-virus software is tightly integrated with the operating system, you may have to install a Ventura-specific version of your software after installing Ventura anyway. Check with the maker of your software.
    • If you connect your Mac to the network using WiFi, select  ► System Settings...=>Network=>Wi-Fi and delete any WiFi networks you don't want to use. (If you don't, your computer may connect to a very slow network during installation, which will slow down your install.)
  3. Install
    • 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.
    • Restart your computer. (I've had problems where my computer hangs on shutdown. Restarting seems to fix it for a while. Don't want this trouble when installing a new OS.)
    • Run the Ventura (macOS 13.0) installer. If you downloaded it, use that copy. Or you can just select  ► System Settings...=>General=>Software Update and install by clicking on the link.
      • If FileVault is enabled on your computer, the installer will ask for a password to unlock the disk.
      • The installer will run for about 15 minutes, then reboot, then run for about an hour, then reboot again. Might ask for your password 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.
      • Eventually you will be presented with a login screen; enter your password.
      • You will see a window about privacy.
      • Next you will be asked if you want to send analytic information to Apple.
      • Then you will be asked if you want light mode or dark mode appearance. (You can change this later.)
      • Then the system will display your desktop. All your files and applications should be there.
    • If Ventura 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" without asking, 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.
    • Select  ► System Settings...=>General=>Software Update and  ► App Store... to make sure you are up-to-date with the latest versions of Apple software. Then run it again to make sure all software is updated. (might take another hour) This step may find additional OS and 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.
  4. Recover
    • Wait for Spotlight to finish indexing (may take several hours). Performance will suck till it finishes.
    • Turn on Time Machine and start your backup.
    • 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 Ventura, you can make some adjustments.


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.


Re-Installing Programming Tools

If you use your computer for programming, you'll need to re-install your tools, which may have release dependent parts. The order presented here worked for me.

  1. (check this) In Terminal, type the command java. If you don't have Java 8 installed, this action will bring up a dialog box: click More Info 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 this) Java is needed for Eclipse and for other Mac applications, such as OpenOffice, 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.
  2. Install the full Xcode package for Ventura using the App Store, and then install the Xcode command line tools from the Xcode menu. This will take a long time, about an hour. (Just using xcode-select won't work for some complex installs, which look for system header files installed by Xcode.)
  3. Homebrew: see my instructions for Homebrew. Basically the procedure is to list your installed software before upgrade, install the OS, reinstall Homebrew, and reinstall your software. You may need new versions of Perl, Python, or Ruby required to install other software: set PERL5LIB correctly or installs will fail with messages about variants.
  4. MySQL: Seems like you can install MySQL 8.0.31 by doing brew install mysql. Have not tried this. If you dumped your database, reload it with mysql < db.sql. MySQL has to be installed before you can install DBD::mysql with CPAN.
  5. MaxMind: If you use Perl module MaxMind::DB::Reader::XS, you must download and install libmaxminddb from before installing the MaxMind module with CPAN. (I had trouble doing this. The instructions say to do ./configure but no such file is provided. Luckily the file left over from Sierra still works.) Install any other libraries that are used by Perl modules at this point.
  6. Perl/CPAN: If you use Perl and Perl modules, install them. Perl 5.26.2 is installed by MacPorts as it installs various modules. ==== check this, might be 5.28.1 ==== See the instructions for installing CPAN for a list of modules I use. This is the time to install Python and Ruby libraries also.
  7. Apache web server:
    • You may need to install Apache using Homebrew. See
    • Homebrew supports PHP 8, 8.1, 8.2. Bout time.

Ventura Observations

Bugs and Surprises in Monterey

The directory :{/usr/local/bin:} is not created by default on Ventura. It is needed for correct operation of Homebrew and Aquamacs. Use Terminal command sudo mkdir /usr/local/bin to create it.

New Features and Changes in Ventura

Lots of new features. Here are a few notable ones.


New "rapid response" security patches can be installed automatically.


A new feature called Stage Manager lets you set up a window with applications related to a task.

Planning for the next version

The next macOS version will released in Fall 2023.

Keep a list of the software and devices you use and depend on, so you can check that they are supported.
