Now the Software Update section of System Preferences lets me update to macOS Catalina 10.15. But before completing a 6 GB download, is this going to give me the option to install 10.15 beta on a separate partition or is this going to blindly update my existing 10.14 installation?
Good news. After the 10.15 beta download completes, the installer starts and after accepting the license, you are shown a screen where you can select where to install the OS. It defaults to the current disk containing 10.14 but there is a "Show Disks" button. Clicking it brings up a list of all other partitions attached to the computer. Many will be grayed out. The drive/partition you wish to choose must be formatted using APFS in order to be selectable as an option.
macOS Mojave will be available to Mac users this fall. But what if you want to look at it earlier?Immediately after the keynote, the Developer Beta of macOS Mojave became available to members of the Apple Developer program. We expect that by the end of June, it will also be available as a public beta. This will enable many more people to download and install it.
Which brings us to Mojave, the newest entry in the continuously evolving operating systems from Apple. It is currently available for download as a beta version with the official release slated for the fall of 2018. It should run on most Macs manufactured after 2012 and may work on earlier models as well.
If you are subject to actual data loss during an upgrade to Mojave, Disk Drill can help even if you have not activated Recovery Vault or Guaranteed Recovery. It is fully compatible with encrypted APFS and Fusion drives. Disk Drill scans your storage devices safely in read-only mode to prevent further data loss and can be used on any peripheral or internal drives. It is an economical alternative to data recovery services, and a free download lets you preview the data recovery that the tool will be able to perform.
When the testing period is over, you'll no longer be able to open the beta build. To install the App Store version of the app, download or purchase the app from the App Store. In-app purchases are free only during beta testing, and any in-app purchases made during testing will not carry over to App Store versions.
Note: To automatically download additional in-app content and assets in the background once a beta app is installed in iOS 16, iPadOS 16, or macOS 13, turn on Additional In-App Content in your App Store settings for iPhone, iPad, and Mac.
Download AndreaMosaic is completely free for personal and commerical use but the license requires that you make AndreaMosaic more popular by giving a reference/credit to AndreaMosaic. Just download and run the preferred setup file. It will install and run the program. To create a mosaic follow the tooltips inside AndreaMosaic. But I strongly suggest you take a look at the manual. For any question contact me at the Helpdesk.
