With OS X 10.8, Mountain Lion, we are able to stop our Macs from sleeping for a period of time from our command line with the caffeinate command. Let's take a look at how to use this command, and some alternatives for older machines.

There's nothing more annoying than a slow or crashing computer.^[1] It doesn't matter if you use Windows or Apple device, you still want it to boot quickly and work fast. However, during the time, computers might become sluggish, and you might find yourself daydreaming about a new device. Though, new Mac might not be the priority in your shopping list. Fortunately, you start fresh without spending the money. It's enough to restore Mac to the earlier date to make it faster or get rid of annoying errors.

Falling Time Mac Os Catalina

Windows computer users have System Restore^[2] feature that allows reverting computer to the previous date. Thus, they can travel back in computer's time before the error, ransomware attack or other problem has occurred.

However, Mac OS X users can take advantage of this feature as well. It's not hard to restore Mac to the previous date. Thus, if you want to speed up your beloved PC, read further to learn more how to perform this task.

Reasons why computers become sluggish

Often Mac or Windows computers become sluggish due to various cyber infections:

• you might accidentally install potentially unwanted program (PUP) during freeware installation;
• you might download illegal content that brought spyware or cryptocurrency miner^[4] to the computer;
• you may have incorrectly uninstalled or deleted applications and corrupted program-related files that caused system errors;
• ransomware attack;
• etc.

However, not only viruses or malicious programs can cause system slowdowns. Even if you are responsible computer users, everyday tasks still diminish Mac performance. Thus, system restore can help to start fresh and enjoy your PC like the first day you got it from the Apple store.

Instructions on how to restore Mac OS to the previous date

Mac restore requires setting up a Time Capsule and using Time Machine. It's a built-in backup software in macOS. It allows creating data backups and restoring them. However, it's not an offline storage utility.^[3] Thus if you are afraid of losing your files or want to backup all your life and keep it safe and sound, you should use external storage device or look up for other Mac backup solution.^[5]

Step 1. Configure a Time Capsule

You won't be able to restore Mac until you set up a Time Capsule. You can perform this task either manually or automatically. However, you will need to use an external drive and connect it to your computer.

However, if you cannot perform this task due to some computer-related problems or virus infection, you will need to repair the hard disk or reinstall the operating system. However, we hope that you won't need these methods.

Automatic Time Capsule set up

Once you connect your external storage device to the computer, you should receive a prompt saying:

'Do you want to use the drive to back up with the Time Machine?'

You should choose Use a Backup Disk Drifteam mac os. option to start the process. After a while, your Time Capsule will be configured, and you will be able to restore Mac.

Manual Time Capsule configuration

However, in some cases, Mac does not deliver previously mentioned pop-up. For this reason, you cannot set up Time Capsule automatically. For this reason, you have to do it manually by following these steps:

1. Open Apple menu.
2. Access System Preferences and choose Time Machine.
3. Click Select Backup Disk option.
   
4. Now you have to choose your external storage device from the available disks list. Then click Use Disk button.

If you want to ensure that your files are protected and cannot be accessed by third-parties, you should hit 'Encrypt Backup Disk' option and create a strong password.

Wait until backup process is over. Indeed, it might take some time if your Mac is full of documents, video files, image and other data. Thus, you have to be patient!

Step 2. Use Time Machine to backup your data

Time Capsule creates backups every single day. Thus, once you set it up, it automatically creates backups for the previous 24 hours. Additionally, it also creates daily backups of the previous month. However, you can speed up this process; you can create a backup immediately after setting up a Time Capsule.

All you have to do is to choose Backup Up Now option from the Time Machine's menu. Wait until it finishes the task and proceed to the third step.

Step 3. Restore Mac to the earlier date

When preparatory work is done (previous two steps), you can start the main task – computer restore with OS X Recovery Tool. Follow these steps:

1. During the system startup, hold down the command key + R to open the recovery tool.
2. Choose Restore From Time Machine Backup option.
   

   Choose 'Restore From Time Machine Backup' option from the macOS Utilities window.

3. If you have few backups, choose the one that was created before particular Mac error or around the date you have noticed system slowdowns or other problems.

Then, you have to wait until Mac restore is finished. One it's done, you can enjoy your PC's performance again!

MAC times are pieces of file systemmetadata which record when certain events pertaining to a computer file occurred most recently. The events are usually described as 'modification' (the data in the file was modified), 'access' (some part of the file was read), and 'metadata change' (the file's permissions or ownership were modified), although the acronym is derived from the 'mtime', 'atime', and 'ctime' structures maintained by Unix file systems. Windows file systems do not update ctime when a file's metadata is changed^{[citation needed]}, instead using the field to record the time when a file was first created, known as 'creation time' or 'birth time'. Some other systems also record birth times for files, but there is no standard name for this metadata; ZFS, for example, stores birth time in a field called 'crtime'. MAC times are commonly used in computer forensics.^[1][2] The name Mactime was originally coined by Dan Farmer, who wrote a tool with the same name.^[3]

Modification time (mtime)[edit]

A file's modification time describes when the content of the file most recently changed. 11042 mac os. Because most file systems do not compare data written to a file with what is already there, if a program overwrites part of a file with the same data as previously existed in that location, the modification time will be updated even though the contents did not technically change.

Access time (atime)[edit]

A file's access time identifies when the file was most recently opened for reading. Access times are usually updated even if only a small portion of a large file is examined. A running program can maintain a file as 'open' for some time, so the time at which a file was opened may differ from the time data was most recently read from the file.

Because some computer configurations are much faster at reading data than at writing it, updating access times after every read operation can be very expensive. Some systems mitigate this cost by storing access times at a coarser granularity than other times; by rounding access times only to the nearest hour or day, a file which is read repeatedly in a short time frame will only need its access time updated once.^[4] In Windows, this is addressed by waiting for up to an hour to flush updated access dates to the disk.^[5]

Quotations on good luck. Some systems also provide options to disable access time updating altogether. In Windows, starting with Vista, file access time updating is disabled by default.^[6]

Change time and creation time (ctime)[edit]

Unix and Windows file systems interpret 'ctime' differently:

• Unix systems maintain the historical interpretation of ctime as being the time when certain file metadata, not its contents, were last changed, such as the file's permissions or owner (e.g. 'This file's metadata was changed on 05/05/02 12:15pm').
• Windows systems use ctime to mean 'creation time'^{[citation needed]} (also called 'birth time') (e.g. 'This file was created on 05/05/02 12:15pm').

This difference in usage can lead to incorrect presentation of time metadata when a file created on a Windows system is accessed on a Unix system and vice versa.^{[citation needed]} Most Unix file systems don't store the creation time, although some, such as HFS+, ZFS, and UFS2 do. NTFS stores both the creation time and the change time.

The semantics of creation times is the source of some controversy.^{[citation needed]} One view is that creation times should refer to the actual content of a file: e.g. for a digital photo the creation time would note when the photo was taken or first stored on a computer. A different approach is for creation times to stand for when the file system object itself was created, e.g. when the photo file was last restored from a backup or moved from one disk to another.

Metadata issues[edit]

As with all file system metadata, user expectations about MAC times can be violated by programs which are not metadata-aware. Some file-copying utilities will explicitly set MAC times of the new copy to match those of the original file, while programs that simply create a new file, read the contents of the original, and write that data into the new copy, will produce new files whose times do not match those of the original.

Some programs, in an attempt to avoid losing data if a write operation is interrupted, avoid modifying existing files. Instead, the updated data is written to a new file, and the new file is moved to overwrite the original. This practice loses the original file metadata unless the program explicitly copies the metadata from the original file. Windows is not affected by this due to a workaround feature called File System Tunneling.^[7]
