macOS 13 Ventura Release Date

macOS Catalina

macOS Catalina (macOS 10.15) is here for the Mac; if you are not already aware, this macOS will kill any 32-bits apps you may have installed on your computer. Apple has been working with developers over the past few years to transition from 32-bit to 64-bit hardware and software technology for the Mac. 64-bit technology can access and utilize significantly more memory and enable faster system performance. At the Worldwide Developers Conference in 2018, Apple informed developers that macOS Mojave would be the last OS version to run 32-bit apps.

You may have noticed the warning, "App" is not optimized for your Mac and needs to be updated... when opening some of your apps over the past few months. This warning appears every 30 days in macOS Mojave, giving users advanced notice that they are running 32-bit software which will not be compatible with future macOS software, starting with macOS Catalina. If you have any software which has not been updated by the software developer as of this writing, you need to contact the developer by opening the app and clicking the application name in the menu bar and choose "About".

If you have purchased your software on the App Store, most of your applications have probably been updated; however, if you have purchased them from a software provider not on the App Store, there is a likelihood some may not have been updated to 64-bit. In addition, some of the 3rd-party accessory software used for printers, scanners, keyboards, etc. may stop working when you upgrade to macOS Catalina, so it is important to check with the manufacturer(s) of your peripherals to verify that updated drivers will are available for macOS Catalina.

If you want to check on the compatibility of your applications prior to installing macOS Catalina, you can do so manually:

• Go to the Apple  Logo in the top left of the menu bar
• Click on "About his Mac"
• Click on the button, "System Report"
• In the Window which opens, go to the list on the left and open the dropdown for "Software"
• Click on "Applications" in the Software list
• When you click on each application, you will see two panes on the right hand side; the upper pane references the application and version, and the lower pane will tell you whether the app is 32-bit or 64-bit. "Yes" means the application is 64-bit and "No" means 32-bit and will need to be updated.

Verifying whether your applications are 32-bit or 64-bit is particularly important if you have critical applications or hardware used in your daily workflow. If you cannot function without that critical app or hardware, contact the software/hardware developer and ask whether a 64-bit version is in progress. If necessary, you may have to look for an alternative. Some accessory device drivers may be found at open-source projects such as CUPS.org or Gimp-print.

Should you choose to not verify the software on your system is 64-bit compliant before installing macOS Catalina, when you do open a 32-bit application, you will see a pop-up box which will tell you that the app or list of apps are "not optimized to run on your Mac". In addition, listed in "Other Features" below Apple says "Restore from snapshot.  If your third-party software is incompatible with an update you just installed, use macOS Recovery to restore from a snapshot of your computer taken right before the installation. macOS and all your apps will work just as they did before you installed the update."

  • Usage reports  Screen Time creates usage reports that show you how much time is being spent on your Mac, which apps are used most, and how many notifications are received. With iCloud, Screen Time combines all your usage information and syncs Downtime settings and App Limits across iPhone, iPad, and Mac.
  • Downtime  With Screen Time, you can schedule downtime so you (or your child) can only use specific apps you’ve approved.

  • Communication Limits*  Communication Limits let you control who your children can communicate with and who can communicate with them throughout the day and during downtime.
  • Managed contact list for children  Parents can use Screen Time to manage the contacts that appear on their children’s devices.
  • Family Sharing  Parents can configure Screen Time from any device — iPhone, iPad, or Mac — and have everything set up for their kids on all their devices.
• Security
  
  • Enhanced Gatekeeper  Gatekeeper will ensure that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time and periodically thereafter. This extends the protection from the app’s source to include automated checks for what’s in the app.
  • Data protections  macOS Catalina checks with you before allowing an app to access your data in your Documents, Desktop, and Downloads folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external volumes. In addition, you’re asked before an app can perform key logging or capture a still or video recording of your screen.
  • Activation Lock  All Mac models with the Apple T2 Security Chip now support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
  • Dedicated system volume  macOS Catalina runs in a dedicated, read-only system volume — which means it is completely separate from all other data and helps improve the reliability of macOS.
  • DriverKit and user space system extensions  Previously many hardware peripherals and sophisticated features needed to run their code directly within macOS using kernel extensions, or kexts. Now these programs run separately from the operating system, just like any other app, so they can’t affect macOS if something goes wrong.
• Find My
  
  • Two great apps in one Find My iPhone and Find My Friends are now combined in a single, easy-to-use app to help you locate the people and devices that are important to you.
  • Find offline devices  Locate a missing device even if it’s not connected to Wi-Fi using crowd-sourced location. When you mark your device as missing and another Apple user’s device is nearby, it can detect your device’s Bluetooth signal and report its location to you. It’s completely anonymous and encrypted end-to-end, so everyone’s privacy is protected.
  • Enhanced location notifications  Location notifications include the ability to schedule notifications for different days of the week, more useful place names, and enhanced privacy controls.
• Approve with Apple Watch
  
  • View passwords  Anywhere you need to type your Mac password, such as viewing passwords in Safari preferences, you can now double-click the side button on your Apple Watch to authenticate on your Mac.
  • Approving app installations  Unlock a locked note, approve app installations, unlock settings in System Preferences, and modify root files, all with your Apple Watch.
    
• Accessibility
  
  • Voice Control  Voice Control is a new way to fully control your Mac, iOS, and iPadOS devices entirely with your voice.
  • Accurate dictation  Voice Control improves on the existing Enhanced Dictation feature using the Siri speech recognition engine, so you get the latest advances in machine learning for audio-to-text transcription.
  • Add custom words  Whether you’re writing a biology report, filling out a legal document, or emailing about a favorite topic, you can add custom words to ensure that Voice Control recognizes the words you commonly use.
  • On-device processing  All audio processing for Voice Control happens on your device, ensuring that your personal data is kept private.
  • Rich text editing  Thanks to rich text editing commands, you don’t have to rehearse before you speak. Making corrections is quick and easy. You can replace phrases by name. Try saying “Replace I’m almost there with I just arrived.” Fine-grained selection also makes it simple to select text. Try saying “Move up two lines. Select previous word. Capitalize that.”
  • Word and emoji suggestions  If you need to correct a word, there’s a new interface just for that. Simply ask to correct a word, and you’ll be presented with a list of suggested replacements.
  • Seamless transitions from dictation to commands  Voice Control understands contextual cues, so you can seamlessly transition between text dictation and commands. For example, say “Happy Birthday. Tap send.” in Messages, and Voice Control sends “Happy Birthday” — just as you intended. You can also say “delete that”, and Voice Control knows to delete what you just typed.
  • Comprehensive app navigation  You can rely entirely on your voice to navigate an app. Comprehensive navigation is provided by navigation commands, names of accessibility labels, numbers, and grids.
  • Navigation commands  Navigation commands give you quick ways to interact with macOS and apps. You can open apps, search the web, open Spotlight, and more.
  • Names  You can easily navigate by telling Voice Control to select the name of an accessibility label for buttons, links, and more.
  • Numbers  Say “show numbers” to see numbers appear next to all clickable items onscreen. Use this to quickly navigate complex or unfamiliar apps. Numbers automatically appear in menus and whenever you need to disambiguate between items with the same name. Just say a number to click it.
  • Grids  If you ever need to touch a part of the screen that doesn’t have a control, use Grid overlays. Saying “show grid” superimposes a grid on your screen and allows you to precisely do things, like select, zoom, drag, and more.
  • Hover Text  Hover Text displays high-resolution zoom of text, text fields, menu items, buttons, and more in a dedicated window. Just press the Control key when hovering over text with your cursor, and a window with zoomed text appears alongside the standard interface — helping you stay contextually aware. Text is crisply displayed in a font and color of your choice. And you can interact with buttons and type right in the zoomed window.
  • Zoom Display*  While using a second display, you can see the same screen up close and at a distance simultaneously. You can keep one monitor zoomed in and another at a standard resolution. Or keep a personal Mac zoomed in while giving a presentation.
  • Simplified tab navigation  VoiceOver users will enjoy simplified keyboard navigation that requires less drilling into unique focus groups. The Tab key more simply advances through selection of elements — such as window stoplights, toolbar buttons, and scroll bars.
  • Punctuation in iCloud  VoiceOver users often customize the way punctuation marks are spoken. These customizations are now stored in iCloud, giving you a consistent experience across macOS, iOS, and iPadOS.
  • Additional international braille tables  macOS Catalina adds more international braille tables and lets you quickly switch between them.
  • Improved VoiceOver support in Xcode  VoiceOver now reads aloud warnings, line numbers, and breakpoints in the Xcode text editor.
  • Display color filters  Users with color vision deficiencies can adjust display colors using new color filter options. Your Mac shifts the colors onscreen, helping you easily differentiate areas of confusion. And you can turn this preference on and off through the Accessibility Options pane using Command-Option-F5.
  • Tint your entire display  A new display option lets you tint your entire screen using a color of your choice. Some users may find that certain color tints help make text easier to read.
• Apple ID Account Information
  
  • One place for your Apple ID account details  Now you can access all your important Apple ID account information right from System Preferences on your Mac.
  • Overview and helpful notifications  A new overview pane allows you to quickly review important tips and notifications to help ensure that your account is properly signed in and secure, and that all the features you expect are set up and working correctly.
  • Basic account and security details  Easily review account details such as your name, contact info, password, security details, payment and shipping info, and email newsletter preferences.
  • iCloud settings  Review and update your iCloud settings and manage or upgrade your storage plan anytime.
  • Media and purchases  Get easy access to your current subscriptions, past purchases, and account settings related to the App Store, iTunes Store, Apple Music, Apple Books, Apple News, Apple TV, and more.
  • blah
  • Family Sharing  View which subscriptions you’re sharing, which services are enabled, who has Ask to Buy turned on, and more.
  • View all your devices  View a list of all the devices you’re signed in to with your account. Review device details such as last backup completed, Find My status, and more.
• QuickTime Player
  
  • Picture in Picture (PiP)  With a single click in the navigation controller, you can play video in a resizable window that isn’t blocked by other windows, allowing you to watch while working on other things.
  • Enhanced Movie Inspector  The Movie Inspector pane shows you even more in-depth technical information about the currently open media file. See key details such as video color space, HDR format, bit depth, scale, and aspect ratio.
  • Open Image Sequence  Create an H.264, HEVC, or ProRes-encoded movie file by navigating to a folder of sequentially numbered images, then choosing your desired resolution, frame rate, and encoding quality.
  • Timecode support  When QuickTime Player opens a media file with embedded timecode, it shows the time information in the onscreen navigation controller.
  • Transparent video support  Transparency in ProRes 4444 files can optionally be preserved when exporting to the HEVC format.
• Home
  
  • HomeKit Secure Video  With a home hub such as an Apple TV or HomePod, securely record video to iCloud when activity by a person, animal, or vehicle is detected by your HomeKit-enabled cameras. Choose to receive notifications when clips are recorded and view them in the Home app on your Mac. In the Home app, a timeline of recordings is available to play from iCloud. You can also share a recording, delete it, or save it to your Photos library.
  • Audio in scenes and automations  HomePod and AirPlay 2–enabled speakers can now play songs, playlists, and radio stations from Apple Music in scenes and automations with your other HomeKit accessories.

  • Cantonese keyboard predictions  The new Cantonese predictions for Traditional Chinese Cangjie, Sucheng, Stroke, and Handwriting keyboards bring more relevant character and emoji predictions to Cantonese users.
  • Improved Japanese predictions  A new neural language model takes words typed earlier in the sentence into account, so predictions are more grammatically consistent and relevant to the subject matter.
  • New fonts for Indian languages  Get 34 new fonts, including four system fonts and 30 document fonts, for languages like Gujarati, Hindi, Kannada, Odia, Punjabi, and many more.
  • New Indian English Siri voices  All-new Indian English male and female Siri voices allow Siri to be more natural and expressive.
  • New dictionaries  New dictionaries include Thai-English and Vietnamese-English.
• Other Features

Mojave macOS and the transition to 64-bit technology

macOS Mojave was released Monday, September 24th and it is amazing. I have been waiting for a very long time for a "dark mode" because I must admit, my eyes need relief since I spend many hours a day on the computer working and gaming.

Apple has been encouraging developers to develop 64-bit software since 2017 and it possible that Apple will prohibit 32-bit software from running on macOS as soon as 2019. Starting with High Sierra version 10.13.4, users will be alerted to update said software to a 64-bit version in preparation for compatibility with future macOS.   So, if you have a 32-bit version of your favorite software, you might want to consider contacting the software developer and asking if and when they will be providing an update.  You can find contact information for your app (when opened) by going to the Menu Bar and clicking on the application name and then "About".  In the meantime, you will be able to use your applications but will receive the following alert every 30 days when you open the app.

How do I find out what applications are 32-bit or 64-bit on my Mac?
