我用OCL制作了一個BOOTABLE USB DRIVE。
插入USB後啟動電腦,按住 OPTION 後看到兩個 EFI BOOT,
但無論選擇哪一個,電腦都會BOOT INTO 現有系統 SONOMA,
沒有安裝 SEQUOIA 的選項,請教教我如何解決。
謝謝。
macOS Sequoia 安裝USB沒製作好,請重新製作

1.先製作一個原本的USB可開機的[安裝macOS系統]

2.完成後,再安裝OCLP [OpenCore Legacy Patcher 2.2.0] 到 USB

3.開機按住 OPTION,可以看到 [EFI BOOT], [安裝macOS系統] ,及原本的作業系統

4.點選[EFI BOOT]進入後,可以再次看到[安裝macOS系統]及原本的作業系統,再點選[安裝macOS系統]即可進行安裝

PS.
1.會看到2個[EFI BOOT]表示你已經在[原本的系統]及[USB]都裝上了OCLP
2.沒看到[安裝macOS系統]表示安裝USB沒製作好

macOS Sequoia...(恕刪)

Problem solved. I did not know I have to keep pressing the OPTION key when
I am using the cursor key to select the EFI.
I had installed the SEQUOIA but what I want is to erase all thing in Fusion Drive and
install a fresh new copy of Sequoia. I had tried to boot into Recovery Mode to erase
the drive but failed to do that. The progress bar won't move at all. I waited for 20 mins already.
Please let me know how to solve this problem.
Many Many Thanks.

試著用ChatGPT來解決你的問題:

### **翻譯(繁體中文):**
問題已解決。我之前不知道,在使用方向鍵選擇 EFI 時,需要一直按住 **OPTION** 鍵。

我已經成功安裝 **macOS Sequoia**,但我想要清除 **Fusion Drive** 上的所有內容,並全新安裝 **Sequoia**。
我嘗試透過 **恢復模式 (Recovery Mode)** 來抹除磁碟,但無法成功,進度條完全不動,等了 20 分鐘仍然沒有變化。
請告訴我該如何解決這個問題。

### **可能的問題與解決方法:**

#### **1. 確保 Fusion Drive 狀態正常**
- 進入 **macOS 安裝工具**(從 USB 開機),打開 **磁碟工具程式 (Disk Utility)**,選擇 **Fusion Drive**,查看它是否顯示為「正常」。
- 如果 **Fusion Drive 已損壞**,可以透過終端 (`Terminal`) 嘗試修復:
```bash
diskutil repairVolume /Volumes/"Macintosh HD"
```

#### **2. 嘗試透過終端完全抹除 Fusion Drive**
如果 **磁碟工具程式** 無法運作,你可以用 **終端 (Terminal)** 來強制抹除整個 Fusion Drive:
1. 在 **macOS 安裝工具**(從 USB 開機)中,打開 **終端**。
2. 執行以下指令來檢查磁碟編號:
```bash
diskutil list
```
找到類似 **Fusion Drive** 的分區名稱(通常是 `disk2` 或 `disk3`)。
3. 先刪除 APFS 容器:
```bash
diskutil apfs deleteContainer /dev/diskX
```
(請把 `diskX` 換成你的 Fusion Drive 編號)
4. 重新建立 Fusion Drive:
```bash
diskutil resetFusion
```
5. 如果 `resetFusion` 不適用,也可以手動合併:
```bash
diskutil coreStorage create Fusion disk1 disk2
diskutil coreStorage createVolume logicalVolume jhfs+ "Macintosh HD" 100%
```
6. 重新啟動,然後用 **磁碟工具** 格式化 **Fusion Drive**,再重新安裝 macOS Sequoia。

#### **3. 嘗試 Internet Recovery (網路恢復模式)**
如果 **Recovery Mode** 進度條卡住,可能是內部磁碟損壞。可以試試 **網路恢復模式**:
1. **關機**,然後按住 **Option + Command + R**,直到看到地球圖案。
2. 進入 **磁碟工具程式 (Disk Utility)** 抹除 Fusion Drive。
3. 下載並安裝 macOS。

如果問題仍然存在,請提供你的 Mac 型號,或錯誤訊息,我可以幫你進一步診斷!

以上,請參考

#### **Possible Causes:**
1. **Fusion Drive corruption** – If the Fusion Drive is damaged or improperly configured, macOS might struggle to erase or reformat it.
2. **APFS Container issues** – If your Fusion Drive is using APFS and has multiple volumes, the installer might be having trouble handling them.
3. **Disk Utility failure** – Sometimes, the built-in **Disk Utility** in Recovery Mode cannot properly erase certain drives.
4. **macOS Recovery Mode issues** – If the Recovery Mode itself is not working correctly, it may fail to erase the drive properly.

#### **Solutions:**

### **1. Use Terminal to Manually Erase the Fusion Drive**
If **Disk Utility** fails to erase the drive, try using the **Terminal** in macOS Recovery:
1. Boot into **macOS Recovery** (restart and hold **Command + R** or **Option + Command + R** for Internet Recovery).
2. Open **Terminal** from the **Utilities** menu.
3. Type the following command to list all disks:
```bash
diskutil list
```
Identify the Fusion Drive disk (usually `disk2` or `disk3`).
4. Delete the APFS container if it exists:
```bash
diskutil apfs deleteContainer /dev/diskX
```
*(Replace `diskX` with the actual disk number.)*
5. If using **Core Storage**, reset Fusion Drive with:
```bash
diskutil resetFusion
```
6. If `resetFusion` is unavailable, manually recreate the Fusion Drive:
```bash
diskutil coreStorage create Fusion disk1 disk2
diskutil coreStorage createVolume logicalVolume jhfs+ "Macintosh HD" 100%
```
7. Once done, exit Terminal, open **Disk Utility**, and format the Fusion Drive as **APFS** or **Mac OS Extended (Journaled)**.
8. Proceed with the macOS Sequoia installation.

### **2. Try Internet Recovery Mode**
If the local **Recovery Mode** is not working, use **Internet Recovery** instead:
1. Restart your Mac and hold **Option + Command + R** until you see a **globe icon**.
2. Wait for macOS Utilities to load and try erasing the Fusion Drive again.

### **3. Create a Bootable macOS Installer and Erase from There**
If neither Recovery Mode nor Internet Recovery works, try booting from a **USB macOS Installer**:
1. Create a **macOS Sequoia Bootable USB** using the following command on another Mac:
```bash
sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB --nointeraction
```
2. Boot from the USB by holding **Option** at startup and selecting **Install macOS Sequoia**.
3. Open **Disk Utility** and erase the Fusion Drive before proceeding with installation.

### **4. Check for Hardware Issues**
If all else fails, the Fusion Drive might have a hardware issue. You can:
- Run **Apple Diagnostics** by restarting and holding **D** at boot.
- If errors are detected, it may indicate a failing SSD or HDD, requiring replacement.

Let me know if you need further assistance!
