macOS Sierra introduces many new features and refinements to Apple's desktop operating system platform, but one is particularly appreciated by Finder fans. As has been long offered in Windows, Sierra now lets users keep folders at the top of a Finder window when sorting files by name.
In OS X El Capitan and earlier, Finder sorts everything by name, mixing files and folders together. In macOS Sierra, there's a new option in the Finder preferences. With Finder selected as the active application, head to Finder > Preferences in the menu bar (or press the keyboard shortcut Command + Comma) to open the Finder preferences window and click on the Advanced tab.
You'll see a new option labeled "Keep folders on top when sorting by name". When this option is checked, Finder will sort folders by name separately at the top of the list and sort the remaining files by name at the bottom.
This is how File Explorer in Windows operates and it may be a preferred way to manage files in Finder for many people. Pre-Sierra users could still separate files and folders by configuring Finder to sort files by "Kind”, but this method sorted all files by their file type and wasn't always ideal. For longtime Mac users who prefer the old sorting method of mixing everything together, Apple thankfully retains the option to switch back. Just uncheck the "Keep folders on top when sorting by name" box in Finder preferences and file sorting in macOS Sierra will work like it used to in El Capitan and earlier.
When you use the volume controls on a Mac to increase or decrease the sound coming from your speakers, those levels increment in whole steps on a scale from one to ten, press the up volume button once, for example, and the volume goes up one step out of ten. However…
If you hold down Shift and Option (Alt) before pressing the volume keys on your keyboard, you could adjust the volume in quarter-steps instead of whole ones. In addition to using this Shift and Option (Alt) combination to control the volume more finely, you can also use it when you adjust the brightness on your Mac. Press Shift and Option (Alt), then press one of the brightness keys on a Mac keyboard, and you'll notice that the brightness changes in quarter-steps. This is nice if you find your display is just a bit too bright or too dim.
When you get ready to sell or give away your Mac, there are some steps you should take. You'll want to back up your computer, disable some features and services, and erase the hard drive.

• Create a backup. Be sure you have an up-to-date backup of your important files and data. Learn how to back up your data in OS X.
• Sign out of iTunes. Open iTunes. From the menu bar at the top of your computer screen or at the top of the iTunes window, choose Account > Authorizations > Deauthorize This Computer. When prompted, enter your Apple ID and password. Then click Deauthorize. Learn more about deauthorizing your computer using iTunes, including how to deauthorize all the computers you've used with your iTunes account.
• Sign out of iCloud. If you use Find My Mac or other iCloud features on your Mac, you should first archive or make copies of your iCloud data. After that, choose Apple Menu > System Preferences, click iCloud, and then deselect the Find My Mac checkbox. Finally, sign out of iCloud. In System Preferences, click iCloud, and then click the Sign Out button. When you sign out of iCloud, you're asked whether you want to remove iCloud data from your Mac. Your iCloud data will remain on any other devices that are using the same Apple ID.
• Sign out of iMessage. If you're using OS X Mountain Lion or later, sign out of iMessage. In the Messages app, choose Preferences > Accounts. Select your iMessage account, then click Sign Out.
• Erase and reinstall OS X. To reformat your hard drive and reinstall OS X, follow these instructions. After you reformat your hard drive and reinstall OS X, the computer restarts to a Welcome screen and asks you to choose a country or region. If you want to leave the Mac in an out-of-box state, don't continue with the setup of your system. Instead, press Command-Q to shut down the Mac. When the new owner turns on the Mac, the Setup Assistant will guide them through the setup process.
Do you use an external drive or a flash drive to store some of your data? Then you might consider encrypting it. It's a bummer to lose a piece of equipment or have it stolen, but what'd take that from bummer to nightmare is knowing that someone may have access to, say, your private financial information.
Here's all you need to do to encrypt the drive and protect it with a password:
• Connect any external drive to the Mac
• Right-click on the external drives name in the Finder and choose "Encrypt DiskName…”
• Set and confirm a password, then set a reasonable password hint, followed by clicking the "Encrypt" button
Do not forget the password or you will lose access to the data on the drive!
• Wait while the encryption takes place
The encryption process can be very quick for smaller drives like USB keys and SD cards, but can take quite a while for large external hard drives used for backups or personal data. Be prepared to wait a bit for anything larger than a few GB in size, as the general encryption-to-GB time ratio seems to be about 1 GB per minute.
Once the drive has finished encrypting and is disconnected, a password will be required before the data can be accessed from the Mac. To maintain the password protection, be sure to uncheck saving the password to the Keychain when asked.
To do this, choose Look For Duplicates from the Card menu. Contacts will do exactly that and, after looking, produce a sheet that tells you how many duplicate cards and entries it's found. By clicking the Merge button in that sheet, you can merge those duplicate cards and entries. Optionally you can also merge cards that have the same name but different information.
