In general, this OS is an excellent tool for manager, tech support and developer. Easy to use and fast integration with the Apple ecosystem, it allows me to perform my task on time.

The ecosystem integration, and frequency update, are easy to use.

Many IT application does not run on macOS yet.

Overall, I use it as my daily OS and can't wait to get some system improvements.

I went for macOS Big Sur mostly because of its reputation as the best operating system for developers. After a while, I would agree, as it provides a wide support for most of the required tools for every developer.

The learning curve (when switching from e.g. Windows) is quite steep, I know some people, that have problems with that - not particularly my case. Some standard features from other OS (Windows, Linux distributions) are missing and I would welcome them. I would say that if it had them, the transition would be smoother.

Big Sur needed to trust the user more and be more open in regards to under the hood controls. Maybe The next version wiuld be better.

Privacy and data security are the main features that I can commend Big Sur on. Split screen and screenshot shortcuts are reliable and easy to use. Very rare OS crashes, so fairly reliable.

Unfortunately, still not a Mac OS fan despite the Big Sur update. Finder is still clunky and file 'move' is very difficult. Settings such as multi monitor config, IPv6 settings etc are buried away and hard to configure. A more simplified access to system settings would be ideal.

Overall experience has been very positive.

I like that this is for ARM64 based processors, which, I think, are superior to Intel based processors. Also the support for iOS and iPadOS applications.

Desktop design is new. I'm not a big fan of design changes just for the sake of change.

Mac os big sur offers quite a lot of changes for old users of mac such as installing IOS apps natively if on the newest hardware, safari has also been supercharged to make one reconsider using other better relied on apps. Overall, if you are on the newest non intel based mac , big sur is a no brainer, if you were on the previous version ie catalina then all the newer features introduced then are further enhanced in big sur.

Mac os big sur has brought a lot of customizability to mac os, allowing deep changes to safari and the interface. Most apps are also quite fast with notable speed in safari over other browsers like chrome. If you also enjoy certain apps on IOs big sur is your best chance to run them on desktop.

If you are running hardware pre 2013 unfortunately it isnt compatible with big sur. Also the upgrade process has to be done very carefully as the compatibilty with externally installed apps has to be verified individually. Some apps could not activate their licenses after upgrade
