Machine + peripheral management – The operating systems controls the whole machine and all the components in there. It also controls peripherals like keyboards, mouse, printers etc. For example Windows control monitor by changing the resolution, mouse by setting the click speed etc.	Machine + peripheral management – MacOS control of computer components are very similar, but almost all of devices need to be bought especially for Macs. For example MacOS can control keyboard by changing the input language. For other devices like iPhone MacOS controls screen by changing it to landscape mode.
Security – Operating systems need to make sure that everything works properly and there is no unauthorised access that can harm your data. Windows has security functions like user accounts with password protection, firewalls which is completely useless and other functions that can be easily bypassed by going to safe mode.	Security – MacOS got security features like blocking the ports that are potential security issues. It also got security features that checks if the downloaded content is safe or not. In email programs attachments are not opened automatically so they can’t harm user computer without his knowledge.
File management – Operating system needs to have file management to show files, create new files, deleting, editing and other functions linked to the files. Windows has his process called explorer.exe to handle the file management.	File management – The program for file management that MacOS use is called Finder. It is pretty the same as Windows’ explorer, it got appropriate icon for every file type, the tree navigation system and trash on desktop.
Device drivers – Drivers are programs that tell the operating system what and how to do with this particular device. For example when you buy new graphic card, to make it work properly with all of its power and efficiency you need to install drivers provided with the card.	Device drivers – Same as Windows’, the drivers are programs that controls the devices. In MacOS case, when the system is closed and you can’t really upgrade anything, every needed driver to run the computer is included in system. But when you want to install new printer, you got to install version of driver for MacOS.

MAC/Apple have always been ahead of windows in the sense of releasing new handy features. For example the MAC has 'DOCK which is essentially task bar of MAC however they allowed you to add or it would automatically add most used programs for example your browser. You can now pin things to the task bar on windows however 'DOCK' was three or so years prior to this. Another feature of the MAC is time machine, it is a built in feature which automatically back up all of your system files,emails and well everything. The part that makes time machine so unique and superior is it's ability to not just keep a spare copy of everything but a copy from each day so you can view how for example a document was one day and choose that over the previous or next day. Time machine does hourly, daily and weekly back ups until your drive is full. Another helpful feature of MAC is dashboard. It provides quick and easy access to widgets. Widgets often include things such as contacts, calendars, events and so on. This is helpful because you don't even have to open the app so if you need to check the date, or message a contact it can be done much more efficiently. The last MAC feature that I'm going to cover is 'cover flow'. Cover Flow was introduced in OS X 10.5 and is based on the iTunes feature which basically allows you to see the contents of a file as a thumbnail.
This is helpful in situations like if you have 2 files with similar names or you forgot what you saved the name as you can view the thumbnails instead of searching through all of your files.
