Snap is a feature that debuted in Windows 7 at its release in 2009. It allows users to drag windows to the edges of their computer screen to quickly snap them into a specific size. If you drag the window to the top, it maximizes the window. If you drag it to the left or right, it fills that half of the display. Then you can adjust them to your liking from there too.
Despite being such a popular feature for several years, OS X only recently caught on to this useful organizational tool in El Capitan. There’s a built-in feature that works similarly to Snap hidden at the top of every OS X window. Still, the way it functions is a bit different from Windows. For more power and control over your window sizes and placement, we’ll also have to turn to a third-party app.
Install snapcraft on macOS. On Apple macOS Yosemite (or later), Snapcraft 3 can be installed via Homebrew and used to build snaps within the macOS environment. Prerequisites: Make sure you have the Homebrew package manager installed; Download and run the Multipass installer to install Multipass; To install snapcraft, open 'Terminal` and enter the following. Apr 13, 2016 Mac’s Split View OS X El Capitan (and presumably future versions of OS X to come) has a feature called Split View built in that mimics Snap for Windows, though it doesn’t work for every. May 27, 2020 Greenshot is completely free, open source, and it runs on both macOS and Windows. LightShot is a Mac Snipping Tool alternative and arguably the fastest way how to take a customizable screenshot. The application features a simple and intuitive user interface, which allows you to select any area on your desktop and take its.
Snapshots are a feature of the Mac's APFS file system that allow you to roll back your Mac to a previous state. A good tool to have when you upgrading the OS. Snapshots are a feature of APFS (Apple File System) that has been part of the macOS since High Sierra. Fujitsu has posted this 'ScanSnap for Mac' compatible driver in order to enable Mac OS users to scan with ScanSnap S300M / S510M / S500M / fi-5110EOXM scanners.
Mac’s Split View
OS X El Capitan (and presumably future versions of OS X to come) has a feature called Split View built in that mimics Snap for Windows, though it doesn’t work for every application.
Split View is hidden behind the green full-screen button at the top left of every window. All you need to do is press and hold this green button. You’ll see that the current app window will automatically resize to take up the left portion on your screen.
Over on the right, an array of windows you have open that are compatible with Split View will appear so you can pick one to fill in the other side.
Tip: Not all applications will work with every Split View because some require more than half of the screen. If this is the case, windows you have open will sit as thumbnails at the bottom with the message “Not available in this Split View.”Just click a compatible window to fill your display with two applications simultaneously. You can even drag the slider in the middle to adjust the sizes of each one.
Tip: You can also launch Split View by four-finger swiping up on your touchpad to open Mission Control. Drag one window up into the Spaces toolbar, then drag another window on top of that to merge them.More Advanced Window Management with Magnet
If you really want to go all out with your window management on a Mac, try out Magnet. It’s currently on sale for $0.99 in the Mac App Store so there’s no better time to get it. Plus it does everything Windows Snap can do and more.
At its core, all Magnet really does is enable windows to intelligently resize at your comment. In addition to having them fill up half the screen like Split View already does, you can fill four corners with four different windows, have three windows with one at the top and two at the bottom, one on the left and two on the right… the possibilities are extensive.
When you first launch Magnet, be sure to grant permissions in System Preferences as it prompts you to do. Once that’s complete, you have one of two options. You can drag a window to the corner or side you want, or use my own preferred method which is the menu bar icon. Magnet’s menu bar icon lists all the sizing shortcuts and even some extras like centering a window. Just click a window, click the icon and choose its position.
Split View and Magnet combined, not only can you mimic Snap, you can go above and beyond what Windows can do.

How to Add Special Characters in Mac and Other Tricks
Snapshots are a feature of APFS (Apple File System) that has been part of the macOS since High Sierra. A snapshot captures the state of an APFS formatted drive, and preserves all the files on the drive, as they appeared when the snapshot was taken. If you ever need to, you can roll back the drive to its previous state.
Apple makes use of the snapshot feature whenever a system update is performed. Before the system update is applied, a snapshot is taken of the startup drive, ensuring that if something goes wrong with the update process, you could recover from the problem quickly and be back right where you were before you started the system update.
In this Rocket Yard guide, we’re going to take a look at APFS snapshots, how they’re created, managed, and deleted, as well as the advantages and disadvantages of snapshots.
Snapshots Take Up No Space, But Can Magnify the Amount of Data Blocks Used
When a snapshot is initially created, it takes up no additional space on the volume. A snapshot essentially marks all the currently used data blocks on a volume to be preserved; that is, no changes can be made to them. At the moment a snapshot is taken, there’s no increase in the space used on a volume.
Note: Apple has supported local snapshots on HFS+ formatted drives since OS X Lion. APFS-based snapshots use an entirely different mechanism even though Apple has continued to use the “local snapshot” nomenclature for both types of file system snapshots. In this guide, we’re specifically dealing with the APFS snapshots.
Snapshots leverage the APFS’s copy-on-write system. When there’s a need to write data, such as when you’re editing a file, a new data block is used to hold the changes you’re making, instead of writing the data back to the original block.
Normally the old data block can then be marked as free and available for use. However, if the block is marked as preserved, such as when a snapshot has been generated, the old block remains and is not freed up for use.
Editing a file can significantly magnify the amount of space being used, as the old versions of the file are retained in the snapshot, while outright deleting a file frees up no space at all since the snapshot will retain all the preserved data.
Creating a Snapshot and Rolling Back a Snapshot is Fast
A big advantage to snapshots is how quickly they can be created. Only the volume’s metadata is being copied, so the process is lightning-fast, especially when compared against conventional backups. Rolling back to a snapshot is also quick; just the metadata needs to be restored since all the actual information in a snapshot data block was never changed.
Deleting a Snapshot is Difficult
Unwinding a snapshot can be a difficult process, as the system needs to go through each data block and remove the preserved setting, decide if the data block still contains active information, and free up the data blocks that aren’t currently in use where it can.
Snapshots Are Not Backups
On the surface, it looks like snapshots perform the same function as a backup, but have the added advantage of being quick and easy to create, as well as providing the ability to use a snapshot to recover from a problem quickly.
Seems pretty good, but snapshots have a few downsides. First up, snapshots are part of the startup drive. They don’t exist anywhere but on the same startup drive as the data you’re trying to protect. That makes snapshots vulnerable to any issues the volume may encounter. Accidently erase the startup drive and the snapshot is gone as well. Drive having some type of errors? The snapshot is likely experiencing the same problem. The point being, don’t rely on snapshots as a backup. You still need a dedicated backup that keeps data stored on a physically separate device. ![Snap Snap](/uploads/1/2/6/5/126589130/153254391.jpg)

Creating Snapshots
APFS snapshots are only supported on drives using the APFS format. If you’re using any other file system, such as HFS+, APFS snapshots will not be available. If you’re using a drive with APFS, you have a few options available for creating and managing snapshots.
Time Machine:Time Machine gained support for APFS snapshots with macOS High Sierra. Some sharp-eyed Time Machine users may have noticed an addition to the description of the types of data Time Machine keeps. When you open the Time Machine preference pane, you’ll see “Local snapshots as space permits” is now part of the description of what Time Machine does.
Time Machine will use APFS snapshots of your startup drive provided it’s APFS formatted, isn’t in Time Machine’s list of excluded items, and there’s a significant amount of free space available.
Time Machine performs the following snapshot management functions:
- Creates a snapshot of the startup volume approximately every hour, and keeps it for twenty-four hours before it is automatically removed.
- Creates a snapshot of the last successful Time Machine backup, and keeps it unless space is needed.
- Creates a snapshot before installing any macOS update.
tmutil: tmutil is a command line tool for controlling Time Machine. It offers a number of actions for creating and managing APFS snapshots. The Terminal app is used with the tmutil commands.
You can find information about using Terminal in the guide:
Tech 101: Introduction to the Mac’s Terminal App, Part One
How to create an APFS snapshot:
Open Terminal and enter the following at the prompt:
tmutil localsnapshot
Press enter or return.
A new snapshot will be created with the current date and time appended to its name.

How to list existing APFS snapshots:
Enter the following at the Terminal prompt:
tmutil listlocalsnapshots /
Press enter or return.
Terminal will list the snapshots stored on the startup drive. You can specify a different drive by replacing the “/” in the command with the full pathname to another drive.
How to delete an APFS snapshot:
To delete a specific snapshot, you need to know the creation date of the snapshot you wish to delete. The easiest way to find the date is to use the listlocalsnapshots command above. It will list each snapshot by name, which includes the data and time appended to the name.
Update outlook for mac high sierra. As an example, if I list local snapshots on my Mac in Terminal I get:
tnelson@Toms-Mac ~ % tmutil listlocalsnapshots /
Snapshots for volume group containing disk /:
com.apple.TimeMachine.2019-12-06-152818.local
com.apple.TimeMachine.2019-12-07-171533.local
The portion of the name after TimeMachine. and before .local are the date and time. If I wanted to delete the snapshot named com.apple.TimeMachine.2019-12-06-152818.local, I would enter the following Terminal command:
tmutil deletelocalsnapshots 2019-12-06-152818
Press enter or return.
Mounting a Snapshot
Aero Snap Mac Os X
It’s possible to mount a snapshot on your Mac’s desktop and use the Finder to restore an older file from the snapshot. There doesn’t seem to be any advantage to doing this versus just using the normal Time Machine interface to find and restore a file, however, it may be interesting to see all the files in a snapshot.
In order to mount the snapshot, you need to create a directory that will be used as the snapshot’s mount point. I suggest using the /private/tmp folder to create a directory named snappy so the mount point will be removed automatically when you log out of your Mac.
At the Terminal prompt, enter the following:
mkdir /private/tmp/snappy
Press enter or return.
Snap For Mac Os X 10 13 Download
To mount a snapshot, you need to know the snapshot’s name, which you can find out using the listlocalsnapshots command outlined above. Once you have the name, you’re ready to mount the snapshot. In this example, I will mount my snapshot named com.apple.TimeMachine.2019-12-07-171533.local.
At the Terminal prompt, I would enter:
mount_apfs -s com.apple.TimeMachine.2019-12-07-171533.local / /private/tmp/snappy
and then press enter or return.
![Snap Snap](/uploads/1/2/6/5/126589130/153254391.jpg)
The snapshot will be mounted on the desktop.
With the snapshot mounted on the desktop, you can use the Finder to browse through the snapshot’s information. You can copy files from the snapshot, but you cannot move, delete, or add to the snapshot.
After examining the snapshot, you can remove it from the desktop by ejecting it (right-click on the mounted snapshot and select Eject from the popup menu).
Restoring a Full Snapshot
If you need to roll back your Mac to the state it was in when a snapshot was taken, such as after a software upgrade that went bad, you can do so by booting into the Recovery environment and using the instructions from the Rocket Yard guide:
How to Restore Data From Time Machine Backups
Cinch For Mac
Use the instructions in the “Restoring a Full Time Machine Backup” section. When you get to the step for selecting a Restore Source, be sure and select the startup drive that holds the local snapshots, and not your Time Machine drive. Outlook for mac high sierra 10.13.3 supplemental update.
Aero Snap For Mac
After that, just follow the onscreen instructions to restore from a selected snapshot.
Warning: All information added after the selected snapshot’s date will be lost when the snapshot is restored.
Snapshots and You
APFS snapshots are a relatively new tool that can be used as part of an effective backup and recovery strategy. Time Machine users have an advantage with the Time Machine app able to manage snapshot creation and deletion for them.
It may be tempting to keep a number of snapshots around to allow you to recover to various points in time. But snapshots should be kept to a minimum so they do not excessively impact your storage usage. Instead, use Time Machine or another favorite backup app for the bulk of your backup needs, and just be aware that snapshots are a recovery option should something go wrong when you install new versions of the macOS.
