Anyone with an iPhone or iPad would benefit from having a macOS-based computer. Additionally, the learning curve for a new user is much less steep than for a Windows computer. Apple has updated its OS for 20+ years, however, still maintains the same basic functionality (turn on/off, open/close apps, etc), the same cannot be said for Windows (Windows Vista, 8, 8.1, 11).
SLES is a good fit for running supported enterprise applications like SAP, HANA, oracle,.. We use it to run all our SAP workloads, and so far everything has worked great. All libraries are right in the repository, all documentation is correct and the support answers really fast in case you have problems.
The support window for service packs after a new SP is released is too short.
Community engagement is low.
There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.
For the breadth of services, features and overall performance, I believe Suse Linux is a great choice for any enterprise. It still has to grow a bit in areas like online help forums and documents, but we are pretty much satisfied with our choice.
It's great for basic support issues. But it's less suited for anything that is either obscure or uncommon, and it is very hard to escalate, unless you've built a relationship with your vendor/salesperson.
macOS just makes sense to me. Each OS has its pros and cons.. macOS works for me. It's well designed, intuitive, and efficient. But it's not cheap... well, macOS is basically free, but you need the hardware to run it, and the hardware isn't cheap. Pick the right tool for the job and for you. And even though macOS may not be thought of in an enterprise environment, it works remarkably well if configured properly. Tools like DEP and ABM from Apple enable device management and lock them to the company. Use an MDM like Jamf to push policies and packages. Jamf can also manage accounts and authentication. JumpCloud is another great product for account management. Although it might not be all included in the box, with the right knowledge, you can build a robust and versatile enterprise Mac infrastructure. You can even do zero-touch deployment in most cases with the correct setup. And Apple employs engineers to help you get it set up right.
SUSE Linux Enterprise Server works well with the SUSE Manager, it really simplifies everything. We also do have SUSE 4 SAP, and the SUSE Manager is able to manage them all, even other (up to date) Linux distributions. Patching has never been that easy and the SALT integration is also working without any problems.
It allows a very small team to manage a large number of servers, due to its automation and manageability.
SAP supports it very well, making it straightforward to manage. There are also "recipes" for Oracle which has all of the requisites to install an Oracle DB; which helps with deployment immensely.
It lets us run large SAP instances in SLES on Power, helping us with support, manageability, and performance.
Support costs are high, but required for SLES for SAP.
