Mac OS Extended vs Mac OS Extended(Journaled)

Mac OS X 10.3 also marked Apple's adoption of Unicode 3.2 decomposition, superseding the Unicode 2.1 decomposition used previously. This change caused problems for developers writing software for Mac OS X. Mac OS X 10.3 introduced a number of techniques that are intended to avoid fragmentating files in HFS+. Mar 25, 2009  With Mac OS 10.4.x, add 'UFS' or 'UFS file system' (kind of like ATM machine or SAT test) to the four above. Again, Apple only recommends 'Mac OS Extended' or 'Mac OS Extended (Journaled)'. With UFS, some third-party applications are not compatible. For drive volumes other than the startup disk, add 'DOS File System' (FAT32) to the list.

The Mac OS Extended is a file system that is also known as HFS Plus. This operating system can either be journalled or not, each with its own pros and cons. Journalling is not exclusive to the Mac OS as other operating systems are also capable of having a journalling system.

Journalling is a failsafe method that prevents unwanted data abnormalities in the disk drive due to a system crash during the middle of a file operation. A file operation as simple as deleting a file could be composed of two or more steps in order to ensure that everything is done properly. If a crash occurs before all the steps are completed, the end result might be cross-linked files, unusable sectors, or any other problem. Tracing these problems later on might take a long time due to the increasingly larger drives that are available today, that is why prevention might be the best overall solution. Journalling creates a list of operations that it is about to perform and checks them as they are done. This way, if it is interrupted somewhere in the middle, it can look back at the list and continue where it was interrupted.

The bad side to journalling is that your operating system would usually take a hit due to the processing power that would need to be devoted to the journalling system itself. Saving and updating files that contain the list of operations take up some CPU cycles and some hard drive bandwidth. The amount of performance hit that you take is rather small, especially if you are a casual user who uses a Mac for browsing the internet or creating documents. Only power users would feel the impact of journalling on their system. CPU and hard drive intensive activities like encoding videos can take a little bit longer to finish with journalling.

Journaled

Summary:
1. Mac OS Extended(Journaled) is just the same as the first but with journalling turned on
2. Journalling is not exclusive to the Mac OS as there are also journalling options in other operating systems
3. Journalling is a failsafe system that keeps a record of each operation before it is performed so that it can be traced back once a crash occurs
4. Journalling adds additional overhead that can result in slower overall performance
5. The performance hit is not that significant to most people but might affect power users

The Apple File System (APFS) is the file system used with Mac devices running macOS 10.13 High Sierra and later, while the older Mac OS Extended file system is available for older versions of macOS. You can still use either file system for your hard drives and attached storage devices, with both having their own pros and cons.

If you can’t decide between APFS vs Mac OS Extended for your drive, you should consider your use case first. The newer APFS format is better for some types of drives, including SSDs, while Mac OS Extended is great for older drives and macOS versions. Here’s a run-through of the pros and cons of both to help you decide.

When to Use the Apple File System (APFS)

Mac Os 11

Most users aren’t interested in the type of file system their drive uses—they just expect it to work. That’s exactly what you get with the now-default Apple File System (APFS) that Mac devices have been using since macOS 10.13 High Sierra was launched in 2017. It’s also used with other Apple operating systems including iOS.

CereProc's 5.0 Mac voices are supported on Lion, Mountain Lion, Mavericks, Yosemite, El Capitan, Sierra, High Sierra, Mojave and Catalina. Download size and disk space usage are around 100MB-150MB. Power PC Macs (built before 2005) are not supported. Please note these voices are for personal use only, e.g. A home user on their own Mac. Tts for windows 10. CereVoice text-to-speech v4.0 is available for Apple Mac OS X, bringing CereProc's high-quality voices to computers running Apple's OS X: 10.7 Lion, 10.8 Mountain Lion, 10.9 Mavericks, 10.10 Yosemite, 10.11 El Capitan and 10.12 Sierra. CereVoice can replace the default Mac voices with a wide range of other accents and languages. Sep 07, 2018  Nothing really exciting here, just your typical Mac text to speech voices. Includes the just the normal U.S. Voices, classic Mac OS X including Alex who debuted in Mac OS X Leopard, and the.

APFS offers a number of speed and optimization improvements compared to HFS+, as well as improvements to data handling. For example, file corruption is significantly reduced compared to Mac OS Extended.

You’ll also notice that copying and pasting files on an APFS drive works almost instantly, thanks to improvements in the way macOS handles file metadata with APFS drives compared to the older HFS+.

The biggest downside to using APFS is that Macs with older macOS versions (macOS 10.12.6 Sierra and older) can’t read, write, or otherwise access drives that use it. If you have an older Mac, you’ll need to keep using Mac OS Extended or use an alternative like ExFAT instead.

If you back up your Mac using Time Machine, you won’t be able to use APFS, either. macOS continues to use the HFS+ file system for Time Machine drives for the time being. If you attempt to use an APFS-formatted drive, macOS will want to format it to HFS+ before you can proceed.

Along with APFS and Mac OS Extended (also called HFS+), you also have other file systems that can be used for external drives, including cross-platform options like ExFAT. For most users, however, APFS is the only file system they’ll need or want to use—but only if they’re (only) using modern Mac devices.

Choosing Mac OS Extended (HFS+) for Hard Drives

While Mac OS Extended (HFS+) is no longer the default file system for macOS installations, it hasn’t been completely abandoned by Apple, and it’s still a useful option for macOS users under certain conditions.

As we’ve mentioned, HFS+ is the default file system of choice for macOS Time Machine backup drives. You’ll need to use HFS+ if you plan on formatting a second hard drive or portable flash drive for use as a Time Machine backup—APFS drives won’t work.

You’ll also need to consider Mac OS Extended if you’re using older and newer Macs together, as older versions of macOS won’t support APFS. Other than functionality, however, there are still a few legitimate reasons why you’d choose HFS+ over APFS—the biggest reason depends on the type of drive you use.

Many of the speed and performance enhancements that APFS brings rely on using a high-speed SSD or portable flash memory drive. If you’re using an older, mechanical drive with a disk platter, those enhancements may seem largely minimal or non-existent.

With that in mind, and for cross-compatibility, you may decide to use HFS+ over APFS. You can format a drive with HFS+ using the macOS Disk Utility app, which you can launch from the Launchpad (Other > Disk Utility).

Using ExFAT on macOS and Windows

While you can only use an Apple file system like APFS and Mac OS Extended for your main system drive, another file system is also worth considering for external drives—ExFAT.

ExFAT is an older file system from Microsoft, intended as a replacement for the even older FAT32 file system used with Windows system drives before the switch to NTFS in Window XP. It removes the 4GB file size limit and the 2TB partition size limit of FAT32 drives and is generally considered a better alternative for flash storage.

If you’re thinking about using ExFAT, you’ll likely have a single objective in mind—sharing files across platforms. ExFAT should only really be used for drives that you plan on using with both macOS and Windows devices, as it’s the only file system that both operating systems support natively.

It is possible for Windows to read APFS and HFS+ drives, but it requires external software to do so. Likewise, macOS can read newer Windows NTFS drives, but not write to them.

Mac Os X Leopard

For owners with Windows and macOS devices, using ExFAT for an external drive is a good option but there are alternatives, such as setting up your own cloud storage or sharing files between your devices over your local network instead.

APFS vs Mac OS Extended: Which Is Best?

There’s no winner in the APFS vs Mac OS Extended battle, as it depends on the drive you’re using. Newer macOS installations should use APFS by default, and if you’re formatting an external drive, APFS is the faster and better option for most users.

Update macbook os x 10.6.8. Mac OS Extended (or HFS+) is still a good option for older drives, but only if you plan on using it with a Mac or for Time Machine backups. If you need a cross-platform option, consider using ExFAT for your drive instead—both Windows and macOS can read these drives without any additional software.
