Plist files can become corrupt when a Mac shuts down or restarts unexpectedly or when an app freezes or crashes. As a result, the app may not open. When you delete a bad preference file, the Mac creates a new plist file that contains all the app's defaults automatically. You have to reconfigure the app's preferences afterward. So, I would appreciate it if someone can let me know how I can get the FULL Catalina Installer from the App Store, NOT just the update. This used to be so simple, and in actuality, I was able to download the full OS 10.15.1 installer from the App Store sometime last month.
The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
Apple’s latest Mac update, macOS Catalina, was released earlier this week, and with it came a flurry of complications both minor and major. For one, this update is the first for Apple to drop 32. Nov 11, 2019 Office 2011 and older versions of Microsoft Office simply do not run in Catalina. They are 32-bit. Apple stops support for 32-bit apps with Catalina. See How to Set up Your Catalina Mac to Run 32-bit apps. Alternatively, you can restore your Mac to pre-Catalina. Restore your Mac from a backup - Apple Support.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.
/best-apps-to-get-on-mac.html. If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
The warning prompt reappears, and you can click Open.*
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
We've updated most current apps to 64-bit architecture. The following versions work in Catalina, but have these known issues.
| Adobe app | Version(s) compatible with Catalina |
|---|---|
| Adobe Creative Cloud apps | 2020 2019 |
| Acrobat Pro & Standard DC | 2019 (subscription or non-subscription) |
| Adobe Acrobat Pro & Standard 2017 | 2017 |
| Adobe Connect | 10 |
| Adobe Digital Editions | 4.5 |
| Adobe Photoshop Elements | 2020 |
| Adobe Premiere Elements | 2020 |
Most older Adobe apps were created using 32-bit architecture and do not work in Catalina. We have no plans to update apps that we no longer support or develop. The following table lists some common 32-bit Adobe apps that are not compatible with Catalina. (It is not a comprehensive list of all older 32-bit Adobe apps.)
| Adobe Product | Status and alternatives |
| Creative Cloud apps – 2018 release and earlier | No updates planned. We recommend that you upgrade to the latest release of Creative Cloud apps. |
| Captivate | Update scheduled end of 2019 |
| Creative Suite apps | No updates planned. We recommend that you upgrade to Creative Cloud. |
| Fuse | No updates planned. Find free characters on Mixamo. |
| Presenter Video Express | No updates planned. We recommend moving to Adobe Captivate. |
| SpeedGrade | No updates planned. Certain features have been integrated into Premiere Pro, which is 64-bit compliant. |
Before you upgrade to Catalina, we recommend that you uninstall your 32-bit Adobe apps. Older uninstallers are also 32-bit apps and don't work in Catalina.
If you already upgraded to Catalina, you can use the Creative Cloud Cleaner tool to uninstall older versions of Creative Cloud apps.
If you've kept Acrobat DC or Creative Cloud apps up to date, they are already 64-bit compliant.
You can update your apps using the Creative Cloud desktop app. See how to update your apps to the latest versions.
