I want to prevent my Mac from slowing down during long coding sessions on macOS. I'm looking for a general roadmap, especially in areas like memory management, energy efficiency, and disk cleanup. Which settings should I review first, which services should I check, and what routine maintenance steps should I take? What practical methods do you recommend to minimize performance loss when working with various development environments? How do you approach this, and which tools/commands do you frequently use? Care to share your thoughts?
Tips and approaches to improve system performance on macOS

Hey buddy, the most critical thing you shouldn't miss to speed up macOS is that there isn't something like "services.msc" in Windows. You need to open "Activity Monitor" in macOS and identify processes that are consuming high RAM for now; for instance, IDEs like Xcode or Docker can sometimes cause memory leaks. When you compare this to "Task Manager" in Windows, doing the same thing in macOS is a bit more manual but just as effective. Seriously, turning off Spotlight indexing also gives a quick boost; stopping the background indexing service like "Cortana" in Windows has the same effect.
For energy saving, try the "High Performance" or "Optimized Battery Usage" options under "System Settings → Battery → Power Mode." There isn't a tool like "TLP" in Linux, but you can make similar settings via CLI using the "pmset" command. I think, while switching energy settings to "High Performance," disabling "App Nap" as well makes a difference, especially during long compilation times; it's the same logic as setting "Power Options" to "High Performance" in Windows.
For disk cleanup, a third-party tool like "CleanMyMac X" is similar to "Disk Cleanup" in Windows. However, the safest way is to run `sudo periodic daily weekly monthly` commands in the Terminal. This triggers the system's automatic maintenance scripts to clean up temporary files, logs, and caches. Lastly, you can move frequently used development environments (VS Code, PyCharm, JetBrains) to a "RAM Disk" to gain performance boosts similar to "RAM Disk" solutions in Windows. If you repeat these steps weekly, even coding marathons on macOS won't slow down.
