Although personal computer processor speed has increased around one-thousandfold since the first Mac was introduced in 1984, storage capacity has easily increased a million times over. Compare 1984’s 400 KB floppy to today’s average desktop drive at 500 GB, which is roughly equivalent to 524,288,000 KB, or 1.4 million 400 KB floppies. Users have responded by moving thousands of pictures and hundreds of hours of music and video, historically stored in analog form, to the convenience and dynamism of digital storage. Likewise, enterprise customers have replaced filing cabinets and storage rooms with Redundant Array of Independent Disks (RAID) arrays and backup tapes. Even though the Internet recently changed our perception of what a computer is used for, it’s clear that the computer’s primary task is still that of a tool to organize, access, and store our stuff.
In this chapter, you will examine the storage technology used by Mac OS X. Storage hardware like disk drives and RAID will be covered alongside logical storage concepts like partitions and volumes. Naturally, you will learn how to properly manage and troubleshoot these storage assets as well. Finally, you will also learn to manage storage security through ownership, permissions, and access control lists (ACLs).
File System Components
Before you begin managing storage on Mac OS X, it is important to understand the distinction between storage, partitions, and volumes. Traditionally, computer storage has been defined by disk drive hardware. After all these years, disk drive hardware still maintains the storage lead, as it has moved from removable floppy disks to enclosed hard disks. However, other more convenient removable formats have become extremely popular as they have increased in capacity. This includes optical media like CDs and DVDs and solid-state storage like SSD, USB key drives, and CompactFlash cards. All are equally viable storage destinations for Mac OS X.
Without proper formatting, though, any storage technology is nothing more than a big empty bucket of ones and zeros, and consequently not very useful to the Mac. Formatting is the process of applying logic to storage in the form of partitions and volumes. Partitions are used to define boundaries on a storage device. You can define multiple partitions if you want the physical storage to appear as multiple separate storage destinations. Even if you want to use the entire space available on a device as a single contiguous storage location, the area must still be defined by a partition.
Once partitions have been established, the system can create usable volumes inside the partition areas. Volumes define how the files and folders are actually stored on the hardware. In fact, it’s the volume that is ultimately mounted by the file system and then represented as a usable storage icon in the Finder. Obviously, a storage device with several partitions, each containing a separate volume, will appear as several storage location icons in the Finder.
Partition Schemes
As mentioned earlier, drives must be partitioned in order to define and possibly segregate the drive’s usable space. Every disk requires at least one partition, but Mac OS X can support up to 16 partitions per disk. You learned the advantages and disadvantages of using single or multiple partitions in Chapter 1, “Installation and Initial Setup.”
Mac OS X supports three different types of partition schemes. This may seem excessive, but it’s necessary for Macs to support multiple partition schemes in order to boot computers using modern Intel processors, support older Mac drives, and use standard PC-compatible volumes.
The three partition schemes supported by Mac OS X are:
GUID Partition Table (GPT)—This is the default partition scheme used by Intel-based Macs. This is also the only partition scheme supported for Intel-based Macs to start up using disk-based storage. However, PowerPC-based Macs running Mac OS X version 10.4.6 or later can also access this type of partitioning, but they will not be able to boot from it.
Apple Partition Map (APM)—This is the default partition scheme used by older PowerPC-based Macs. This is also the only partition scheme that PowerPC-based Macs can start up from. However, all Intel-based Macs can also access this type of partitioning.
Master Boot Record (MBR)—This is the default partition scheme used by most non-Mac computers, including Windows-compatible PCs. Consequently, this is the default partition scheme you will find on most new preformatted storage drives. This partition scheme is also commonly used by peripherals that store to flash drives such as digital cameras or smart phones. Even though no Mac can boot from this type of partitioning, all Macs can access MBR partitioning.
Obviously, if you have any additional drives formatted with APM or MBR, you will have to repartition those drives in order for them to be bootable on an Intel-based Mac. But if you don’t plan on ever using the additional drives as a system disk, there is no advantage to repartitioning. Also, you should keep MBR drives unmodified if you intend to keep those drives backward-compatible with generic PCs or peripherals.
Volume Formats
The volume format defines how the files and folders are saved to the drive. To maintain compatibility with other operating systems and provide advanced features for newer Mac systems, Mac OS X supports a variety of storage volume formats.
Volume formats supported as startup volumes for Mac OS X:
Mac OS Extended (Hierarchical File System Plus, HFS+)—Mac OS Extended, also known as HFS+, is the legacy volume format designed and supported by Apple for Macintosh computers. HFS+ itself is an update from the earlier Mac OS Standard (HFS) format. HFS+ supports all the advanced features required by Mac OS X, including Unicode filenames, rich metadata, POSIX Permissions, access control lists (ACLs), UNIX-style links, and aliases.
Mac OS Extended, Case-Sensitive (HFSX)—This Mac OS Extended format adds case sensitivity to the file system. Normally Mac OS Extended is case-preserving but case-insensitive. This means that a normally formatted Mac volume will remember what case you chose for the characters of a file’s name, but it cannot differentiate between similar filenames where the only difference is the case. In other words, it would not recognize “MYfile” and “myfile” as different filenames. By adding support for case sensitivity, Apple resolved this issue. However, this is generally an issue only for volumes that need to support traditional UNIX clients, like those shared from Macs or Xserves running Mac OS X Server.
Mac OS Extended, Journaled (JHFS+) or Mac OS Extended, Case-Sensitive, Journaled (JHFSX)—This feature, enabled by default on Mac OS X, is an option for the Mac OS Extended format that adds advanced file system journaling to help preserve volume structure integrity. The journal records what file operations (creation, expansion, deletion, and so on) are in progress at any given moment. If the system crashes or loses power, the journal can be “replayed” to make sure operations in progress are completed, rather than being left in a half-completed, inconsistent state. This avoids both the possibility of volume corruption and the need to run a lengthy check-and-repair process on the volume after a crash.
Volume formats supported as read/write in Mac OS X:
Mac OS Standard (HFS)—This is the legacy volume format used by the classic Mac OS. This format, though a precursor to HFS+, is not supported as a startup volume for Mac OS X.
File Allocation Table (FAT)—FAT is the legacy volume format used by Windows PCs and still used by many peripherals. This format has evolved over the years, with each progressive version supporting larger volumes; FAT12, FAT16, FAT32. Apple’s Boot Camp supports running Windows from a FAT32 volume, but Mac OS X itself cannot start up from such a volume. Boot Camp is covered in Chapter 6, “Applications and Boot Camp.”
UNIX File System (UFS)—UFS is the legacy native volume format supported by Mac OS X. UFS served as the default UNIX file system for decades. Starting with Mac OS X v10.5, though, UFS volumes are no longer supported as startup volumes. Further, Disk Utility does not support the creation of UFS volumes.
Volume formats supported as read-only in Mac OS X:
NT File System (NTFS)—Windows 7, Windows Vista, Windows XP, and Windows Server all use this as their native volume format. Once again Boot Camp supports running Windows from an NTFS volume, but Mac OS X itself cannot write to or start up from such a volume. Further, Disk Utility does not support the creation of NTFS volumes.

ISO 9660 or Compact Disk File System (CDFS)—This is a common standard for read-only CD media. Note, however, that “Mac formatted” CD media can contain HFS-formatted volumes.
Universal Disk Format (UDF)—This is a common standard for read-only DVD media. Again, note that “Mac formatted” DVD media can contain HFS-formatted volumes.

Just like the Windows operating system, the MacOS operating system has a hidden Library folder full of settings you shouldn’t really touch. Deleting some or all of these settings will at best force you to reinstall certain apps, and at worst, cause the whole system to collapse and require a complete reinstall.
But there may be times when accessing the Library folder is necessary. For example, many apps put backups in the Library folder and you may want to back up the backup. Or you might be customising your Mac, which will need access to certain library folders.
Here is how to get there and not cause your Mac to collapse in a cloud of dust in the process.

What Is The Library Folder On MacOS?
The library folder is the area of your MacOS computer where app settings are stored. When you install a program, a folder is created in the Library for all of the essential settings. This can be anything from plugins, preference files and log files.
It’s hidden because basically some people are just plain clumsy and quite often don’t know what they are deleting. It’s only when it’s too late when they realise that something they just deleted should have been kept.
So you could say that Apple is protecting you against your own worst impulses!
How To Find The Hidden Library Folder On MacOS
There are two ways to get to the hidden Library folder if you are confident enough of not triggering a nuclear apocalypse. But the second way is only really feasible when you know where to look.
First Method (The Easiest)
Go to Finder and drop down the “Go” menu. You’ll see that the Library folder is not listed.

To make the Library folder appear, press the “Alt” key (also known as the Option key) at the bottom left of your keyboard. The Library folder will now appear.
Click on the Library folder option to be taken straight to the folder.
The problem though with this method is that this is very temporary. As soon as you take your finger off the alt key, the Library folder will disappear again.
Second Method (Not Difficult)
Once you know the path to the folder (by following the previous method), you can then use the path to go directly to the Library folder.
At the top of the Library folder, you will see the exact path (location) of the folder on your computer.

With that in mind, go back to Finder’s Go menu and at the bottom, you’ll see this option :

Choosing “Go to Folder” will bring up a box where you can type the path to the Library folder. Hitting the “enter” key will then take you straight there.
Even better, until you input the path to a different folder, the path to the Library will remain in the “Go to Folder” box.

When it is gone, dropping down the menu arrow on the right hand side will show you a list of previous folders you went to, and the Library one will be there too.
Conclusion
There used to be a way to keep the Library folder showing permanently. But as of High Sierra, the Terminal command no longer seems to work.
However, keeping the folder permanently visible isn’t a good idea since you might delete a system-critical file. Besides, as you have just seen, it is not difficult at all to go to the folder when you need it.
