Carbon Copy Cloner and ChronoSync have developed workarounds SuperDuper remains incompatible at this point, although an older version can create data-only backups. Unfortunately, that also makes creating a bootable duplicate difficult. Catalina moved macOS to its own read-only volume, and Big Sur goes a step further by applying cryptographic signatures that make it even harder for an attacker to compromise the operating system. The other app category that continues to have trouble with Big Sur are backup apps that make bootable duplicates. In particular, those who haven’t yet upgraded past 10.14 Mojave may have to upgrade or replace 32-bit apps that ceased working starting with 10.15 Catalina. If you think this applies to you, you might engage us to help you review and plan your upgrade. Most apps have websites which list supported system versions and known issues. You may be able to learn more at RoaringApps, or by checking with the developer of your older apps. Most software under steady development has been updated for Big Sur by now, but some workflows rely on older versions of apps where an upgrade isn’t practical or possible, or on obsolete apps that will never be updated. Some people should continue to postpone moving to Big Sur due to software incompatibilities. There are a few things to watch out for, and preparation is essential.
Upgrading is not an if question it’s a when question.
#SUPERDUPER AND BIG SUR UPDATE#
If you’re more than two versions behind, Apple is no longer offering security updates for your Mac. Most Macs should already be running Catalina today, and you should plan to update to Big Sur in the next six months. Apple makes the upgrade process easy (though time-consuming) but upgrading can create workflow interruptions and may break apps you depend on. At the same time, it’s important to stay in sight of the cutting edge for security reasons and to take advantage of advances from Apple and other developers.
We’re careful when it comes to recommending upgrades to new versions of macOS.
#SUPERDUPER AND BIG SUR INSTALL#
Our experience with Big Sur has been good! If you want to install Big Sur, it should be safe now that Apple has released several bug-fix updates.
