Most of the online discussions about macOS Tahoe have revolved around the UI design, what Apple calls Liquid Glass. Personally, I like the design, but it’s understandable that some people have grown used to the previous, more staid interface. What’s surprising is that so much ire has been focused on graphic design elements (such as pixel alignment), rather than looking at the big picture. I’ve found that Tahoe is not only extremely stable, but has the best backwards application compatibility I’ve seen in years. The only bothersome issue I’ve experienced on my Mac is Safari occasionally freezing on some websites. This may have been resolved in Tahoe 26.1.
For anyone using Sequoia, it’s probably safe to upgrade to Tahoe at this time, with the caveat that anyone running professional applications should check with their app developers. Some professional applications might not be officially supported yet. As an example, Final Draft doesn’t list Tahoe as being supported. When I reached out to its tech support, I wasn’t able to get an answer on compatibility.
