The iCloud and Documents features have been a real relief for me when it comes to organization and storage—they’re truly great. While I enjoy many other aspects of the system, those features are by far the most beneficial for my needs. **What do you dislike about macOS Sierra?** I’m not happy that it’s outdated and no longer gets security updates. That’s a major concern for me, particularly given the existence of infiltration tools like Pegasus, which was developed by the NSA in Israel. **What problems is macOS Sierra solving and how is that benefiting you?** Overall, it's a comprehensive operating system. As with any new OS, there are always fresh features and benefits that stand out—at least until the next update or version arrives.

I use macOS for college **Rating:** 4.5/5.0 stars **Reviewed by:** Pruthviraj P. | I am student, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** August 14, 2025 **What do you like best about macOS Sierra?** One of the new things I really like about macOS Sierra is the integration of Siri on Mac, which makes multitasking easier, like searching files or checking quick updates without leaving my work. Another useful feature is Universal Clipboard, where I can copy something on my iPhone and instantly paste it on my Mac, which saves a lot of time during coding and project work. I also find iCloud Drive Desktop and Documents sync very helpful, because it keeps all my important files accessible across devices. And lastly, the Optimized Storage feature is something I appreciate since it automatically manages space by storing older files in iCloud and freeing up local storage. **What do you dislike about macOS Sierra?** One area where macOS Sierra can improve is in the availability and compatibility of apps. Many apps and games are either costly or not supported on macOS compared to other platforms, which sometimes limits flexibility for students and developers. The Mac App Store still lacks a wide variety of apps, and some professional tools or games require extra effort to install. Another improvement could be in thermal management—since many Mac models don’t include cooling fans or advanced vapor chamber systems, heavy tasks like coding, running simulations, or gaming can cause performance drops and occasional lag. If Apple improves app support and optimizes performance during high workloads, the overall user experience would be much better. **What problems is macOS Sierra solving and how is that benefiting you?** The main problem in Mac OS is sometime is very laggy when you not shut down and restart from 5 to 7 days and very less other software support like photo shops and very costly price. I think Mac want to make optimise software for their devices and improve Apple Intelligence also, Apple Intelligence is not have any knowledge and very slow. I think Apple want to make their Siri and Apple very smart for customer experience. ### 6. macOS Sierra: Fast, Smart, and Seamlessly Integrated **Rating:** 5.0/5.0 stars **Reviewed by:** Urvish M. | Sr. Digital Marketing Executive, Small-Business (50 or fewer emp.) **Reviewed Date:** December 12, 2025 **What do you like best about macOS Sierra?** macOS Sierra delivers a perfect blend of speed, simplicity, and smart features.
