## 项目历史与用法

gptsync is the GPT-to-MBR partition table synchronization utility from the rEFIt EFI boot toolkit. Its niche is Intel Mac dual-boot maintenance, where legacy BIOS-style operating systems expected an MBR view of a disk that was really partitioned with GPT.

### 项目历史

rEFIt began as an EFI boot menu and maintenance toolkit for Intel Macs. Its version history records a first public release on 2006-03-02 and says version 0.7, released on 2006-05-14, added a tool to synchronize GPT and MBR partition tables.

The rEFIt project later stopped active maintenance and pointed users toward rEFInd, a fork. gptsync remains packaged separately in Homebrew as a small system utility extracted from that older rEFIt codebase.

### 采用历史

gptsync mattered most during the Intel Mac and Boot Camp era, when hybrid GPT/MBR layouts were a practical compatibility layer for booting Windows or other legacy systems.

The tool's adoption is therefore narrow but historically useful: it appears in package managers because disk-repair and dual-boot workflows sometimes need the utility without installing the full rEFIt boot menu.

### 使用方式

The utility reads a device's GPT partition table and synchronizes the legacy MBR view. It is a low-level disk tool, so usage belongs in recovery, bootloader, or dual-boot maintenance contexts rather than routine application workflows.

### 为什么软件包爱好者会关心

gptsync is a classic small extracted utility: package managers keep it around because it solves a specific historical systems problem and has almost no substitute inside general application stacks.

### 时间线

- 2006-03-02: rEFIt 0.1 first public release.
- 2006-05-14: rEFIt 0.7 adds the GPT/MBR synchronization tool.
- 2007-03-25: rEFIt 0.9 improves gptsync filesystem and partition handling.
- 2010-03-07: rEFIt 0.14 adds support for additional partition types in gptsync.
- 2013-03-29: rEFIt site states the project is no longer actively maintained and points users to rEFInd.

### Related projects

- rEFIt is the parent EFI boot menu and maintenance toolkit.
- rEFInd is the successor fork named by the rEFIt project page.
- GPT fdisk solves adjacent GPT and hybrid-MBR maintenance problems, but it is a separate project.
