Question: Q: GUID partition map or Apple partition map
I have seagate external portable hard-drive 1 TB, and I will be using with following Mac’s.
- 13″ White MacBook (Intel Core 2 Duo) running Snow Leopard
- 13″ MacBook Air (Intel Core i5) running Lion
- iMac running Lion
What partition map I should use, GUID or Apple when formatting external portable hard-drive?
Once more question, I want to format it with HFS+ type. Is HFS+ synonym for Mac OS Extended Journaled type?
MacBook, Mac OS X (10.6.8)

GUID + OS X Extended Journaled (aka HFS+)
Apr 26, 2012 11:25 AM
The solution I used when couldn’t save files on my Seagate external hard drive from my MacBook Air was to do a partition on my Seagate 1TB external hard drive. If you follow the next steps it will take you 5 minutes to do it from step 3. I hope this helps
- Connect your external hard drive to your MacBook Air
- Save all the information you already have on your Seagate external hard drive on your Mac or any other device that allows you to do so.
3. Go to Finder and click on the Applications option from the Favorites section
4- Click on Utilities and double click on Disk Utility
5- Click on your Seagate external hard drive to select it
6- Click on the Partition tab that appears at the top on the right hand pane
7- Click on the Current tab to select how many partitions you want from the drop down (you can select from1 to 16) it is totally up to you.
I will assume you only want 2 partitions
8- Click on the top window (partion1) and give a name on the Name field. I’ll assume you want the first partition is for Windows so you would call it WINDOWS if you want.
9- On the Format field select MS-DOS (FAT) from the drop down.
10- On the Size field Select how many GB you want to reserve for this first partition; I selected 200 GB
11- Now, click on the second window (partition2)
12- Give a name on the Name field. I’ll assume you want the second partition to be Macintosh so you would call it MACINTOSH if you want to.
13- On the Format field select Mac OS Extended (journaled) from the drop down.
14- On the Size field Select how many GB you want to reserve for this second partition; I selected 800 GB,
15- Click the Options button to select PC Partition Scheme to enable a partition for use on a Windows computer. Select Master Boot Record.
16- Click on the Apply button

КАК: Типы разделов Apple на жестком диске — 2021
40+ скрытых функций iOS 12 для iPhone и iPad. Apple про это не рассказывала! (Декабрь 2021).

Table of Contents:
Типы разделов, или как Apple относится к ним, схемы разделов, определяют, как карта разделов организована на жестком диске. Apple напрямую поддерживает три разных схемы разделов: таблицу разделов GUID (глобально уникальный идентификатор), таблицу разделов Apple и главную загрузочную запись. С тремя доступными картами разделов, которые следует использовать при форматировании или разделении жесткого диска?
Понимание схем раздела
Таблица разделов GUID: Используется для дисков запуска и без запуска с любого компьютера Mac с процессором Intel. Требуется OS X 10.4 или новее.
Маки на базе Intel могут загружаться только с дисков, использующих таблицу разделов GUID.
На компьютерах Mac на базе PowerPC, работающих под управлением OS X 10.4 или более поздних версий, можно монтировать и использовать диск, отформатированный в таблице разделов GUID, но не может загружаться с устройства.
Карта Apple Partition: Используется для запуска и без запуска дисков с любым Mac на базе PowerPC.
Mac на базе Intel может монтировать и использовать диск, отформатированный с помощью Apple Partition Map, но не может загружаться с устройства.
На компьютерах PowerPC можно монтировать и использовать диск, отформатированный с помощью Apple Partition Map, а также использовать его как загрузочное устройство.
Основная загрузочная запись (MBR): Используется для запуска компьютеров DOS и Windows. Может также использоваться для устройств, для которых требуются форматы файлов DOS или Windows. Одним из примеров является карта памяти, используемая цифровой камерой.
Выбор и изменение схемы раздела
Изменение раздела схема требует переформатирования диска. Все данные на диске будут потеряны в процессе. Будьте уверены, резервное копирование чтобы вы могли восстановить свои данные, если это необходимо.
Запустите Disk Utilities, расположенную в папке / Applications / Utilities /.
В списке устройств выберите жесткий диск или устройство, схема разделов которого вы хотите изменить. Обязательно выберите устройство, а не какие-либо базовые разделы, которые могут быть перечислены.
Перейдите на вкладку «Разделение».
Дисковая утилита отобразит используемую схему томов.
В раскрывающемся меню «Схема тома» выберите одну из доступных схем. Обратите внимание: это схема томов, а не схема разделов. Это выпадающее меню используется для выбора количества томов (разделов), которые вы хотите создать на диске. Даже если отображаемая в данный момент схема тома совпадает с той, которую вы хотите использовать, вы все равно должны сделать выбор из выпадающего меню.
Нажмите кнопку «Option». Кнопка «Option» будет подсвечиваться только в том случае, если вы выбрали схему тома. Если кнопка не подсвечена, вам нужно вернуться к предыдущему шагу и выбрать схему тома.
Из списка доступных схем разделов (GUID Partition Scheme, Apple Partition Map, Master Boot Record) выберите схему разделов, которую вы хотите использовать, и нажмите «ОК».
Чтобы завершить процесс форматирования / разбиения, просмотрите Disk Utility: Разделите свой жесткий диск с дисковой утилитой.

Question: Q: GUID or Apple Partition Map
I have two (and a half) questions:
I have an WD 250GB IDE Hard Disk I want to use for Time Machine.
1. Does it matter if I choose GUID or Apple Partition Map for an IDE drive?
2. If I don’t intend to use this drive as a start up disc can I just use Apple Partition map anyway?
2.5 Whats the advantage of GUID anyway?
iMac 2.0, iBook G4, Mini G4, Mac OS X (10.5.1)

1. My understanding is that Time Machine will not recognize a drive that is not GUID. Period.
2. Extrapolating from http://en.wikipedia.org/wiki/Applepartitionmap and some experiences of other users who were having trouble with Boot Camp because their drives were not formatted GUID, it sounds like if you wanted your external disk to be bootable for both your Intel iMac and your PPC iBook and mini, then you would want the Apple Partition Map. I won’t claim that my extrapolation is accurate, but it’s derived from the idea that an intel mac can boot from an APM partition, but I don’t know if the PPC will boot from GUID. So because you don’t intend to use the drive as a startup disk, you can use GUID anyway. 🙂
2.5 See http://en.wikipedia.org/wiki/GUIDPartitionTable GUID is for Intel machines and is an improvement over MBR (Master Boot Record).

As long as you do not plan to use it to install a fresh version of OS X then it doesn’t make a real difference. Intel Macs can boot from both APM and GUID partitioned drives. You just cannot install an Intel version of OS X on an APM partitioned drive.
GUID provides for on the fly altering of existing partitions non-destructively. It also permits the creation of both HFS and MSDOS partitions on the same drive.
Dec 29, 2007 5:48 PM
Well, I would recommend go GUID if you are using an Intel Mac, and using the drives for Time Machine backup.
But *Mr. Lobotomy*, here’s an interesting thing you might want to know — when I first connect my Maxtor One Touch 1TB FW 800 drive to my iMac for Time Machine backup, I formatted it as a normal Journaled disk (that was before I read about the GUID partitioning), the back up actually went well. i.e. Time Machine «sees» the drive and performed the back up as usual.
But after I read about GUID, I just reformat/repartition it and re-run Time Machine again, so far so good.

Thanks for your help guys!
I have a mixture of Intel and PPC Macs & don’t intend to use this for booting OSX and so I chose to use Apple Partition Map.

«Use «Apple Partition Map» partition scheme if the disk will be used with Time Machine and a PowerPC-based Mac.
Use «GUID» partition scheme if the disk will be used with Time Machine and a Intel-based Mac.»
APM does not work for both so you need to partition if the drive is big enough or get another drive.
Dec 30, 2007 1:24 AM
I originally just plugged in my old backup disk that was formatted for APM & everything worked fine with my intel mac.
Then I read that you are supposed to use GUID with an intel mac. so I reformatted it to GUID.
After this but I had problems with Time Machine stopping during the first backup i.e. *WITH* GUID so..
I finally formatted the disk as Apple Partition Map — even though its attached to an Intel Mac and everything works wonderfully again.
Seems very temperamental!
Thanks for all your help though:) I will buy a new disk later on in the spring.

The Different Partition Format Types on Mac
When you attach a storage disk to a Mac with the purpose of erasing or repartitioning it, you’ll be presented with the option of selecting one of the three available partition maps: GUID Partition Map, Master Boot Record, and Apple Partition Map. In this article we will explain what a partition scheme is and which one to pick when formatting a drive.
What Is a Partition?
The fixed-sized subset of a disk drive treated as an individual unit by the operating system (in our case macOS) is defined as a partition. On every drive there are multiple partitions, and for this you will need a partition table or partition map – maintained by the operating system – to detail the status of the partitions.
Download CleanMyMac X from MacPaw’s website and clean up to 500MB of junk data from your computer while enjoying all the features of the software without major limitations.
GUID Partition Map
This is a standard for the layout of the partition table on a storage disk using globally unique identifiers (GUIDs). As part of the Unified Extensible Firmware Interface (UEFI) standard, GUID is a bootable standard for systems with EFI firmware such as macOS. Non-Intel Macs won’t support this bootable standard, hence the only option available to them is the Apple Partition Map (APM).
Apple Partition Map
Used on disks formatted for use with 68k and PowerPC Macs, the Apple Partition Map is the scheme that defines how the data is organized. Starting with OS X Tiger, both APM and GUID partitions can be used for accessing volumes, but PowerPC-based Macs can only boot from APM disks. While Intel-based Macs generally boot from a GUID Partition Table, they are all able to start the operating system from APM and Master Boot Record (MBR) using the BIOS-Emulation called EFI-CSM.
Master Boot Record
Introduced by IBM in 1983 to support the 10MB hard disk, the Master Boot Record is a type of boot sector developed for use with IBM PC systems. It is currently used for Windows partitions formatted as MS-DOS (FAT) or ExFAT.
Choosing a Partition Map
Now you know which partitioning map is which, the next time you insert an external drive or want to partition the built-in storage disk of the Mac, it will be easier to choose between the available options.
When formatting or erasing a volume with Disk Utility, you’ll see a format menu prompt asking you to choose from:
- Mac OS Extended (Journaled)
- Mac OS Extended (Journaled, Encrypted)
- Mac OS Extended (Case-sensitive, Journaled)
- Mac OS Extended (Case-sensitive, Journaled, Encrypted)
- MS-DOS (FAT)
- ExFAT
- APFS (macOS High Sierra’s new file system)
- APFS (Encrypted)
- APFS (Case-sensitive)
- APFS (Case-sensitive, Encrypted).
Be aware that APFS is compatible only with macOS High Sierra and higher, so earlier versions of OS X or macOS won’t mount an APFS volume. If you want maximum reach, Mac OS Extended (Journaled) is the right choice.
Below the file system format, the Disk Utility dialog box will list another contextual menu, the partition map scheme, which gives you another great tool to create targeted volumes. If you are looking to format a disk that will be shared with Windows users, the MBR scheme and MS-DOS (FAT) are the best choices. For drives used with Intel-based Macs only, the GUID Partition Map should the option to go for.
If you don’t see the partition map scheme option, it is likely because Disk Utility doesn’t list all volumes. This will prohibit Disk Utility from erasing the disk and show you an error message. To address this issue, you should click on the View button located in the top-left side of the Disk Utility dialog box and select “Show All Volumes”. From that point on, Disk Utility will ask for your partition map preference, and the formatting process will be smoother.
