Mac Os X Catalina Update


Open 'System Preferences' and click on the 'Software Update' icon. If you have an update available it will list the version of macOS that you will be updating too, and what is going to change. To start the update there will be an 'Update' button. Note: this is on macOS Catalina as older versions require that you use the 'App Store' to update. We’ll be using the third party macOS Catalina patcher tool to download the full installer on to your Mac. Simply follow the steps below to get started. Head over to the dosdude1 website and click on “Download Latest Version” to begin downloading the macOS Catalina Patcher on to your system. Once the download is complete, click on the.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:

  • macOS Catalina 10.15 hardware requirements
  • macOS Mojave 10.14 hardware requirements
  • macOS High Sierra 10.13 hardware requirements
  • macOS Sierra 10.12 hardware requirements
  • OS X El Capitan 10.11 hardware requirements
  • OS X Yosemite 10.10 hardware requirements

Download macOS using Safari on your Mac

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

  • macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
  • macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
  • macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion

Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

  • macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
  • OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
  • OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Recommend switching to Docker

I finally switched to using Docker for local development on macOS. While the following tutorial works for macOS Catalina, it has limitations. I recommend following my latest tutorial on installing Apache, MySQL, and PHP on macOS using Docker.

Note: This post assumes you followed installing Apache, PHP, and MySQL on Mac OS X Mojave and have since upgraded to macOS Catalina. If you did not follow the original post, you should follow installing Apache, PHP, and MySQL on macOS Catalina.

When Mac OS X upgrades it overwrites previous configuration files. However, before doing so it will make backups. For Catalina the original versions may have a suffix of mojave or be copied to a backup folder on the Desktop. Most of the time, configuring your system after updating Mac OS X is simply a matter of comparing the new and old configurations.

This post will look at the differences in Apache, PHP, and MySQL between Mac OS X Mojave and macOS Catalina.

Updating Apache

Mac os x catalina download

Mac OS X Mojave and macOS Catalina both come with Apache pre-installed. As noted above, your Apache configuration file is overwritten me when you upgrade to macOS Catalina.

There were a few differences in the configuration files. However, since both Mojave and Catalina run Apache 2.4, you could simply backup the configuration file from Catalina and overwrite it with your Mojave version.

However, I encourage you to stay up-to-date. As such, you should take the time to update Catalina's Apache configuration. First, create a backup and compare the two configuration files for differences.

Now edit the Apache configuration. Feel free to use a different editor if you are not familiar with vi.

Uncomment the following line (remove #):

In addition, uncomment or add any lines you noticed from the diff above that may be needed. For example, I uncommented the following lines:

Finally, I cleaned up some of the backups that were created during the macOS Catalina upgrade. This will help avoid confusion in the future.

Note: These files were not changed between versions. However, if you changed them, you should compare the files before running the commands.

Updating PHP

Mac Os X Catalina Update Apple Id Settings

Mac OS X Mojave came with PHP version 7.1 pre-installed. This PHP version has reached its end of life. macOS Catalina comes with PHP 7.3 pre-installed. If you added any extensions to PHP you will need to recompile them.

Also, if you changed the core PHP INI file it will have been overwritten when upgrading to macOS Catalina. You can compare the two files by running the following command:

Note: Your original file may note be named something else. You can see which PHP core files exist by running ls /etc/php.ini*.

I would encourage you not to change the PHP INI file directly. Instead, you should overwrite PHP configurations in a custom PHP INI file. This will prevent Mac OS X upgrades from overwriting your PHP configuration in the future. To determine the right path to add your custom PHP INI, run the following command:

Note: It appears Catalina does not include the PHP Zip extension. This is a popular extension used by many packages. This was one of the reasons I switched to using Docker.

Updating MySQL

MySQL is not pre-installed with Mac OS X. It is something you downloaded when following the original post. As such, the macOS Catalina upgrade should not have changed your MySQL configuration.
