Preparing For macOS 13 Ventura

Preparing for macOS 13 Ventura

1. Check whether you have a compatible Mac from this list:
   • MacBook (2017 or newer)
   • MacBook Air (2018 or newer)
   • MacBook Pro (2017 or newer)
   • Mac mini (2018 or newer)
   • Mac Studio (2022 or newer)
   • iMac (2017 or newer)
   • iMac Pro (2017 or newer)
   • Mac Pro (2019 or newer)
   NOTE: If you are not sure whether you have a compatible Mac check our macOS 13 Ventura Frequently Asked Questions article before proceeding.
2. Ventura has a dedicated Signed System Volume - this means if you install it in the same APFS "container" as another version of macOS you will have issues booting. If you wish to install macOS Ventura on the same storage device as older versions of macOS (such as a dual boot configuration) you must create a new "container" (partition) for macOS Ventura and install it to that separate container/partition!
3. Check you do not need any of the following as Ventura does not directly include/support them:
• PostScript and Encapsulated PostScript files are no longer available in the Finder Quick Look Preview - you will need to open them manually in a supported graphic application
• PHP - use Homebrew to install it or install via a third party software stack such as MAMP/MAMP PRO
• Kernel extensions used by online storage services such as Microsoft OneDrive, Google Drive, Box, and Dropbox - if you use any of these applications update to the latest versions before installing Ventura and make yourself aware of the changes to the way cloud storage works. Microsoft has in-depth information on the new "Files On-Demand" feature and TidBits has great coverage in their Apple's File Provider Forces Mac Cloud Storage Changes article.
• Python 2.x - use Python 3 instead (once macOS 12.3 is installed, run the stub /usr/bin/python3 in Terminal which will prompt you to install the latest Xcode developer tools that includes Python 3.x)
• legacy System/Kernel Extensions (KEXTs) - no longer supported
• VPN connections via L2TP over IPSec now require "HMAC-SHA-256" security at the third-party server end - make sure your VPN server is compatible!
• 32-Bit Applications - no longer supported
• Legacy media formats - no longer supported
• TLS certificates signed with the SHA-1 hash algorithm - no longer supported
• Apple's hardware RAID and Apple's RAID Utility - application removed
• Installing on and booting from FireWire storage - no longer supported
• .safariextz packaged Safari Extensions - Safari 14 in Ventura does not support them
• Legacy NPAPI browser plug-ins including Adobe Flash - Safari 14 in Ventura does not support them
• Playlist XML files - Ventura splits iTunes into separate applications but also removes support for Playlist XML files - many popular DJ applications no longer work in Ventura and will need to be upgraded
• The Dashboard feature - it is no longer available in the Mission Control System Preferences
• Legacy smart card support that uses TokenD - no longer supported
• The ability to run AppleScripts/use Scripting Additions - see this in-depth article
• The ability to run macOS Server
• The ability to fully run applications that utilise OpenGL
• Back To My Mac - no longer supported
• Proxy Automatic Configuration (PAC) via FTP or File URL schemes - no longer supported
• Messages support for AIM, Yahoo, Googla Talk and Jabber accounts - no longer supported
• PPTP VPN - no longer supported
• Rosetta for running PowerPC software - no longer supported
• Web Sharing - no longer included
• Xgrid Sharing - no longer included
• X11 - XQuartz may need to be reinstalled if you use it
4. If you have a third party SSD installed in your computer check to see if it needs a firmware update before installing Ventura.
5. Make sure you are connected to the internet (preferably with a fast connection and with a large or no data cap in place).
6. Make sure you have an Apple ID (use the iTunes or App Store application to create one if necessary e.g. go to Macintosh HD > Applications > App Store > Store menu > "Create Account…" to get started if you don't have an Apple ID).
7. Consider whether you want the Mac App Store Apple ID to be the same for services such as iCloud, iTunes, etc if you are going to use them.
8. Check you have enough disk space:
• macOS 13 Ventura installer = ~12.5GB
• macOS 13 Ventura installation (from macOS 10.12 Sierra or later) = ~30GB
9. Backup and/or clone your computer.
10. Check that your favourite software is Ventura compatible.
11. Temporarily disable any third party disk encryption software.
12. Temporarily disable any anti-virus/malware software.
